RealTechTalk (RTT) - Linux/Server Administration/Related

We have years of knowledge with technology, especially in the IT (Information Technology) industry. 

realtechtalk.com will always have fresh and useful information on a variety of subjects from Graphic Design, Server Administration, Web  Hosting Industry and much more.

This site will specialize in unique topics and problems faced by web hosts, Unix/Linux administrators, web developers, computer technicians, hardware, networking, scripting, web design and much more. The aim of this site is to explain common problems and solutions in a simple way. Forums are ineffective because they have a lot of talk, but it's hard to find the answer you're looking for, and as we know, the answer is usually not there. No one has time to scour the net for forums and read pages of irrelevant information on different forums/threads. RTT just gives you what you're looking for.

  • ImageMagick Convert PDF Not Authorized


    You'll have to edit the policy.xml file to fix this:

     convert -density 300 output.pdf agreement.jpg
    convert.im6: not authorized `output.pdf' @ error/constitute.c/ReadImage/454.
    convert.im6: no images defined `agreement.jpg' @ error/convert.c/ConvertImageCommand/3044.

    sudo vi /etc/ImageMagick*/policy.xml

    #change
    #   <policy domain="coder" rights="none" pattern="PDF" />
    # to

      <policy domain="coder" rights="read|write" pattern="PDF" />

     

    After this conversion should work and it applies to other file types in policy.xml


  • ImageMagick Converted PDF to JPEG some files have a black background solution


    Use these flags:

    convert -alpha flatten -alpha remove "output.pdf" ljll.jpg
     

    And even the pesky black backgrounds should be gone after converting to jpg


  • Linux Mint Mate Customize the Lock screen messages and hide username and real name


    This is a security hole in my opinion and should be plugged by editing the lock screen ui layout:

     

    vi /usr/share/mate-screensaver/lock-dialog-default.ui

     

    #find these objects and set the visible property to false
    object class="GtkLabel" id="note-tab-label"
    object class="GtkLabel" id="auth-username-label>
    object class="GtkLabel" id="auth-realname-label"

     

    Actually I had to remove the entire child statement:

     


  • Ubuntu/Gnome/Mint/Centos How To Take a partial screenshot


    By default printscreen or alt print screen will get the whole desktop or the application in focus, respectively.  But what if you want to select a portion of the screen?

    gnome-screenshot:

    ksnapshot

    compiz

    This is a nicely integrated solution

    sudo apt-get install compizconfig-settings-manager

    Then open the settings wizard and go to Extras and check off the "Screenshot" Option

     

    You should be able to hold the Windows Key and drag to take a screenshot now (does not work on Linux Mint 18 though).

    You can also change the initiate key by clicking on Screenshot in Compiz:

     

     


  • ssh how to verify your host key / avoid MIM attacks


    SSH helps keep us secure in many ways, one of those is the host-key fingerprint which is unique.  If you have been connecting to an SSH server that you've made no changes to and suddenly ssh warns that the key doesn't match then you have a problem.

    But how about connecting to an existing server for the first time on a new machine or client?

    A lot of new clients calculate it using an SHA256 hash but it is not as easy on your host machine to produce the same style hash without some hacking around.

    The authenticity of host 'somehow (172.16.5.2)' can't be established.
    RSA key fingerprint is SHA256:alalalalleieieieieiala.
    Are you sure you want to continue connecting (yes/no)?

    So we can get the MD5 hash by using this option:

    ssh -o fingerprinthash=md5 user@host
    The authenticity of host 'somehow (172.16.5.2)' can't be established.
    RSA key fingerprint is MD5:aa:sldka;:ksdkjd::kala:kfdkls:1.
    Are you sure you want to continue connecting (yes/no)?
     

    How do we get the md5 hash on our host?

    ssh-keygen -l -f /etc/ssh/ssh_host_key.pub
    aa:sldka;:ksdkjd::kala:kfdkls:1 /etc/ssh/ssh_host_key.pub (RSA1)
     

    On newer versions you will need to do it like this:

    ssh-keygen -l -f /etc/ssh/ssh_host_key.pub -E md5


  • Cisco IP Phone CP-8845 8800/8900 Series How To Reset To Factory Settings Instructions


    This would be crucial especially if the phone is hardened, not being able to reset or change settings could prevent a phone registering in a new environment or even when migrating from office to office.

    Here is Cisco's guide (timing is everything and it is more tricky than trying to jail break your iPhone):


    Step 1 -- While powering up the phone, press and hold #.

    Step 2 -- When the light on the mute button and handset light strip turns off and all other lights (line button, headset button, speakerphone button and select button) stay green, press 123456789*0# in sequence.

    When you press 1, the lights on the line buttons turn red. The light on the select button flash when a button is pressed.

    If you press the buttons out of sequence, the lights on the line button, headset button, speakerphone button, and select button turn green. You will need to start over and press 123456789*0# in sequence again.

    After you press these buttons, the phone goes through the factory reset process.

    Do not power down the phone until it completes the factory reset process, and the main screen appears.

    Here is an alternative description some have had better luck with:

    Step 1   Unplug the phone:
    • If using PoE, unplug the LAN cable.
    • If using the power cube, unplug the power cube.
    Step 2   Wait 5 seconds.
    Step 3   Press and hold # and plug the phone back in.
    Step 4   When the light on the Mute button and handset light strip turns off and all other lights (Line button, Headset button, Speakerphone button, and Select button) stay green, press 123456789*0# in sequence.

    When you press 1, the lights on the line buttons turn red. The light on the Select button flashes when a button is pressed.

    If you press the buttons out of sequence, the lights on the line button, headset button, speakerphone button, and Select button turn green. You need to start over and press 123456789*0# in sequence again.

    After you press these buttons, the phone goes through the factory reset process.

     

    *Just be forewarned again that it may take a few tries but it does work.

  • ls how to list ONLY directories


    The key thing is the "-d" flag and the */ at the end of the path. 

    Just do this:

    ls -d */

    It would list all directories in the pwd

    If you want a path do this:

    ls -d /var/log/*/

    /var/log/apt/         /var/log/hp/         /var/log/samba/
    /var/log/ConsoleKit/  /var/log/installer/  /var/log/speech-dispatcher/
    /var/log/cups/        /var/log/mdm/        /var/log/upstart/

  • How to encrypt your SSH private key file id_rsa


    ssh-keygen -p -f /path/to/your/id_rsa

    Enter new passphrase (empty for no passphrase):

    After that your rsa private key will be encrypted which is a layer of protection and security in the event that somehow someone acquires your key and tries to access servers that the key is authorized on.

  • Firefox Cannot Hit Enter Key In Address Bar and Location History Not Working


    Opening Firefox from the CLI reveals the following as the cause of the error:


    Query failed: Error: Error(s) encountered during statement execution: no such table: moz_favicons

    The symptoms of this issue are that in the address bar you cannot hit enter to browse to a site/url/address and your history cannot be accessed, nor does your history show up in the address bar when typing previously used addresses.

    This usually happens because you've restored places.sqlite from a NEWER version of Firefox where the structure of the database has changed.  The solution is to upgrade to a newer version of Firefox.

    Eg. your source browser is Firefox Version 65 and your destination was running Firefox 50 so this is why it happens.


  • Cisco Unified Communications Manager / CUCM IP 8.6,10,12 Install Error Solution


    Install Errors on Version 12:

    This error happened on QEMU emulator version 2.11.1 pve-qemu-kvm_2.11.1-5
     on Proxmox/Debian but installing on QEMU .12 on Centos 6 did not produce the error.

    *Update it is not related to the OS or QEMU version.  This happened in Centos 6 too after a second install. 

    What really causes this even though you successfully installed already using the same settings and same machine?

    The problem is related to IO, I believe there is some sort of timer on the database install portion and the install declares itself dead and stops if a certain amount of queries or files are not copied within a certain amount of time.  Don't believe me, take a normal HDD and load it up with a few VMs, see if CUCM installs.  Then add more CUCMs and try to install again and you will at some port have too little IOPS to successfully complete the install. 

    I have installed successfully but CUCM seems picky about the order of steps (eg. if you configure the wizard later or now).  It also seems to need 4096MB of RAM at the most and a single CPU to avoid the error.  I am going to make a step-by-step guide as it seems very finicky to avoid this problem on the DB install process.

    Critical Error

    The installation has encountered a unrecoverable internal error.  For further assistance report the following information to your support provider.

    "/usr/local/cm/script/cm-dbl-install install PostInstall 12.01.10000 12.0.1.10000-10 /usr/local/cm/ /usr/local/cm/ /common/log/install/capture.txt" failed (1)

    The system will now halt.

    Continuing will allow you to view diagnostic information before halting.

    This is a hack but is the simplest fix to this bug:

    echo "mkdir -p /var/run/sshd;service sshd restart" > /etc/rc.local
     

    Basically we just need to create /var/run/sshd and restart SSHD and it will be good and SSH will start once again.


  • nmap how to scan for all ports and not just the 1000 most common ports


    nmap by default only scans the most common, 1000 ports.

    How about if you want all ports because some services may be listening on non-standard ports?

    Just use the -p- switch for all ports or -p1-65535

    nmap -p- somehost.com


  • Windows 7,8,10 and Server 2008, 2012, 2016, 2019 Read Only Attribute Won't Go Away


    I have seen this in a few rare cases after a reboot, where all folders and files will have the Read Only Attribute.  If you uncheck it, it will just come back.  It is more of a filesystem issue in Windows than a configuration issue and it looks like when Windows detects a badly corrupted filesystem that it will make things read-only, sort of like Linux would.

    If you are Administrator or the owner of the folder and this is happening it is probably due to the reasoning mentioned below:

    You can try this command:

    attrib -r +s c:somepath

    If it's just Windows being annoying/buggy the above should work.

    But if it won't work and you may start noticing all folders have this read only attribute.

    This issue is normally caused by filesystem errors and running chkdisk can normally fix it.

  • Cisco Unified Communications Manager 12 Install Errors on Proxmox/KVM


    The strange thing is that usually the first install or two will work on any new machine but then it suddenly won't.  I had this experience on  QEMU 2.13 on a different machine. There is something finicky or buggy about the CUCM installer even when choosing the same virtual hardware specs.

    qemu-kvm command:

    /usr/libexec/qemu-kvm -version
    QEMU PC emulator version 0.12.1 (qemu-kvm-0.12.1.2-2.506.el6_10.1), Copyright (c) 2003-2008 Fabrice Bellard

    This is the critical part and it is found by mounting /dev/sda6 using libguestfs:

  • Local Vs Universally Administered MAC Address NIC Refuses to come up


    2,6,A or E is what the second digit of your MAC address must be otherwise a lot of OS's will not work.  They will say the NIC is down/not connected even though it is.

    This is because if the second digit is not set properly it will not view as a valid MAC or device uplink.  This is especially an issue with VMs whether in QEMU etc.. if you are making your own MAC.

    MAC address is invalid

    c4:d1:aa:e5:10:05

    To fix it just change the c4 to c2, c6, ca or ce

    MAC address is valid / correct

    However the one not enabled by default is the one in "Enterprise Phone Configuration".

    Enable "Cisco Camera" and then reboot your phones to enable it.


  • Windows 7, 8, 10, Windows Server 2008, 2012, 2016, 2019 How To AC97 Audio Drivers and Other Unsigned Drivers


    Oops did you get this error trying to install an oldschool driver and think it is hopeless in a new version of Windows?

     

    First of all it is almost never a program compatibility issue:

     

     

    Solve it by going to the control panel and booting into the F8 mode startup options:

    Click "Troubleshooting Common Computer Problems"

     

    Click on "Recovery" on the Left side menu and then click on "Restart now"

     

    After your PC restarts click on Troubleshoot

     

     

    Then click on "Startup Settings"

     

     

     Click on "Startup Settings" below and then the "Restart Button"

     

    Choose the "Disable Driver Signature Enforcement" option, this will allow us to install our oldschool drivers properly.

     

    Now install your driver whether from the setup.exe or if you manually install from the Control Panel (in this case we are installing AC97 sound drivers)

     

     

     

     

     

    Now instead of faililng like last time you will be prompted to install the driver or not to install it. Obviously you will click "Install this driver software anyway" so the install completes!

     

      

    After that you're all good.

  • tftp Linux xinetd verbose logging


    It is much more useful to have meaningful and detailed logging from tftp to see what is or isn't happening especially for VOIP and other embedded device appications:

    Edit the file:

    vi /etc/xinetd.d/tftp

    Change the server line like this:

            server_args             = -s /var/lib/tftpboot --verbose
     

    Restart xinetd:

    service xinetd restart


  • Linux delete unused tap devices automatically


    This will find all tap devices and try deleting all of them.  Of course don't run this if there is a chance an unused tap device is necessary and would not be created by the script ro application using it.

    tunctl -d $tap

    done


  • Linux qemu-kvm How To Enable Soundcard in Guestl

  • QEMU-KVM Windows and Server Guest Installs Mouse Tracking Pointer Location Solution


    You may have noticed if you are running QEMU/KVM manually that in Windows the the position of the physical mouse does not match where the mouse is positioned within Windows.

    There is an easy command to pass to qemu-kvm or qemu-system (whatever you call your binary):

    -usbdevice tablet

    The above flag will fix your mouse pointing problems whether you are running Windows 95, 98, NT, XP 2000, 2003, Vista, 7, 8 10 or Server 2000, 2003, 2008, 2012, 2016 or 2019 etc... 


  • SSH Keep Alive To stop Disconnections


    Are you tired of coming back to your computer only to find your SSH connections have been broken?  Even worse are the ones that hang where it appears to be connected but it is really not.

    The one option you have is an SSH client side modification to send KeepAlive packets, sometimes this can also keep up your WiFi connection and stop it from disconnecting you as well.

    To make the keep alive changes for your just yourself (not system wide)

    vi ~/.ssh/config

    Host *
        ServerAliveInterval 60
        ServerAliveCountMax 2
     

    ServerAliveInternal 60 = keep alive time of 60 seconds (change according to your needs)

    ServerAliveCountMax 2 = how many packets in that time that can fail before we disconnect or declare ourselves a dead connection.

    To make the changes system wide (by default for all users) then edit the /etc/ssh/ssh_config file

    vi /etc/ssh/ssh_config

    Host *
        ServerAliveInterval 60
        ServerAliveCountMax 2


  • Linux How To Disable SATA NCQ For Better Performance


    This is the closest way to disabling it without using the "libata.force=noncq" kernel boot option is to set the queue to a depth of 1 which doesn't actually disable it.

    Change the sdc below to match the device you want to disable NCQ for.

  • the sign-in method you're trying to use isn't allowed. For more info, contact your network administrator - solution for active directory


    This is usually because the Group Policy forbids that user or group from logging in.

    1. run "gpmc" (not "gpedit.msc" as that is for local computer settings when you are not using Active Directory) or go to Administrative Tools and Group Policy Management.
    2. Edit the default domain policy like below

    You should also check under "User Rights Assignment" that your user or group is listed under the "Allow logon locally setting"

    Domain Active Directory Group Policy Security Settings, User Rights Assignments Allow User Group To Logon Locally

    After that check policies like "Deny logon locally".  Any user or group there won't be able to login, so make sure you remove them if they are supposed to have access.


  • gsmartcontrol for Windows to Check the SMART S.M.A.R.T status


    gsmartcontrol is a free tool that let's you see the status of the SMART parameters so you can check things like temperature, reallocated sectors, bad sectors etc.. to give you a better idea of your drive health.

    Download it here.

    gsmartcontrol is a very useful tool in Windows to check your HDD / Hard Drive health status.

    In my experience you should NEVER trust that everything is OK just because SMART says  it has passed the health check.

  • WebRTC Vulnerability Shows Local IP Address Even When Using a Proxy or VPN Firefox Fix And Disable Solution


    If you visit a site that exploits the WebRTC vulnerability including whatismyipaddress.com it may show "Local IP Address" which would be the real IP of your machine.

    The vulnerability works on Windows and Linux machines (contrary to false information on the web which claims it only affects Windows).

    The above works and happens even if you are using a proxy or VPN account like ProVPNAccounts.com

    It is easy to fix the WebRTC IP Address Leak Vulnerability in Firefox and similar browsers in About:Config

    Go into about:config and then search for "peerconnection.enabled"

    Set it so the value is "false" like the screenshot from Firefox below.


  • chroot in Linux Howto Simple and Easy Guide


    chroot which stands for change root allows you to virtually operate in another operating system even though you haven't booted it.  It is commonly used to deploy new distros, applications and to fix a broken Linux/Unix install or prep a new system image without having to physically boot the drive or disk.

    So in this example let's say we have a drive that has a Linux OS installed on /dev/sdb1 and we have mounted this partition on /mnt/sdb1

    The key point is to edit the "chrootdevpath" to match where your intended chroot target is actually mounted to.

    After that the bash script below mounts dev, proc and sys into the chroot path so you can interact with all hardware and devices (you can even use this to install grub to sdb).

    chrootdevpath=/mnt/sdb1

    for mount in dev proc sys; do

    mount -o bind /$mount $chrootdevpath/$mount

    done
    #now let's chroot into our dev path /dev/sdb1
    chroot $chrootdevpath

     

    The above is what I find to be the easiest way of chrooting  since you don't have to type any commands aside and you just have to modify one variable and the rest is done for you.

  • Linux Over VNC VMWare How To Switch Virtual Terminals Console Without Using Ctrl+Alt+F1


    This is a common issue that I haven't seen many answers for on the internet.  When you are using Linux as your host machine and you are connecting to another Linux machine over VNC you CANNOT use Ctrl+Alt+F1 to change virtual consoles as it sends the keys to your actual local machine.

    In many versions of Linux you can cycle through virtual terminals including over VNC using this:

    Alt + Left Arrow or Alt + Right Arrow

    This does not seem to work if you are running Xorg already though (at least in Linux Mint). 


  • Skype For Business 2015 and 2019 Guide, Reference, Howto and Troubleshooting Solutions


    https://docs.microsoft.com/en-us/powershell/module/skype/?view=skype-ps

     

    Troubleshooting Client Connectivity Issues

    The first step is to enable full logging in the Skype Client itself and then check the log on the client side.  In Windows this normally means going to the Skype client "settings" and then "Enable Full Logging".

    After that you can open Event Viewer, click on the Application Log and see what entries for "Lync" come up (yes it is known as Lync despite the fact the product itself is now called Skype 2015 or 2019 for business).

    Further Troubleshooting on the Front End Server Pool or Edge Server Pool

    The first step here is to really just check th "Lync Server" log under "Event Viewer" and the "Applications and Services Logs"


  • Centos 6 or 7 no DHCP IP during startup on first boot or reboot solution


    This is usually because of STP causing a delay in the negotiation.

    Edit your ifcfg script eg:

    /etc/sysconfig/network-scripts/ifcfg-eth0

    Add a LINKDELAY of 30 seconds or whatever works for you:

    LINKDELAY=30
     

    After that you should have an IP during bootup.


  • Debian / Mint / Ubuntu net-tools packages provides netstat, ifconfig, route, arp and other classic network admin tools


    The net-tools command brings back all of the oldschool tools that we're used to:

    • /bin/netstat
    • /sbin/ifconfig
    • /sbin/ipmaddr
    • /sbin/iptunnel
    • /sbin/mii-tool
    • /sbin/nameif
    • /sbin/plipconfig
    • /sbin/rarp
    • /sbin/route
    • /sbin/slattach
    • /usr/sbin/arp
       

    To install it just do an:

    apt-get install net-tools

    Of coures this applies to all of the main Debian distros whether we are talking Ubuntu, Mint etc etc..


  • Linux Mint XWindows Ubuntu MATE or Cinnamon How To Restart The GUI / Graphics / Session if it freezes without losing current windows or programs


    Uh oh, so you're working on some super l33t code or other stuff that is super important and Linux Mint's MATE or Cinnamon window manager freezes.  This means maybe you can move your mouse but you can't click anything, you can't Alt + Tab to another program but everything appears to be working other than that.

    The first thing you would do is Ctrl + Alt + F1 (or whatever virtual terminal you want) and get into the Linux bash prompt (the black screen where things really happen :))

    Sometimes people will try killing the mint-panel or filemanager as this can sometimes be the cause of it.

    So you've tried the basics, tried to restart the mint-panel or caja filemanager but it doesn't work?

    You're probably close to rebooting, or booting your PC out of the window at this point.  But wait there is Ctrl + Alt + Backspace (but don't do this).  You would lose all of your current open windows

    Linux MINT Mate How To Restart the GUI without losing open windows

    DISPLAY=:0 marco --replace&

    Linux MINT Cinnamon How To Restart the GUI without losing open windows

    DISPLAY=:0 cinnamon --replace&

    Ubuntu Linux How To Restart the GUI without losing open windows

    DISPLAY=:0 unity --replace&

    The key thing is to use the --replace because that means to replace the existing session so the windows and open programs you have are preserved.


  • Linux bash prompt why does it not show username@host and the current directory?


    Perhaps you've just seen this in the bash prompt:

    -bash-4.1#
     

    Instead of the expected user@hostname#

    It is probably because you are missing .bash_profile or .bashrc in your home directory

    Check for yourself:

    ls -al ~/|grep -E ".bash_profile|.bashrc"
    -rw-r--r--.  1 root root       176 May 20  2009 .bash_profile
    -rw-r--r--.  1 root root       176 Sep 22  2004 .bashrc

    If you are missing either just take these default files that pull from /etc/bashrc and will give you what you want:

    .bash_profile

    # .bash_profile

    # Get the aliases and functions
    if [ -f ~/.bashrc ]; then
        . ~/.bashrc
    fi

    # User specific environment and startup programs

    PATH=$PATH:$HOME/bin

    export PATH
     

    .bashrc

    # .bashrc

    # User specific aliases and functions

    alias rm='rm -i'
    alias cp='cp -i'
    alias mv='mv -i'

    # Source global definitions
    if [ -f /etc/bashrc ]; then
        . /etc/bashrc
    fi
     

    Once you've sorted this out just login again or open a new bash shell and things should be all good again


  • Microsoft SQL Server Check What Version is Running

    Complete!

    Create your first container!

    Let's check the available templates first:

    ls /usr/share/lxc/templates/
    lxc-altlinux   lxc-busybox  lxc-cirros  lxc-download  lxc-gentoo        lxc-opensuse  lxc-plamo  lxc-ubuntu
    lxc-alpine  lxc-archlinux  lxc-centos   lxc-debian  lxc-fedora    lxc-openmandriva  lxc-oracle    lxc-sshd   lxc-ubuntu-cloud

    We use the lxc-create command, the relevant parts below are as follows:

    -n = the name of the container

    -t = template type (so if we see lxc-debian) we would type "debian"

    -r = release (in Debian there is wheezy, sid, stretch etc..) that correspond to specific versions

    -a = architecture (most commonly amd64 for 64bit or i386 for 386)

    -p = the path this is optional but if you want it somewhere else like /mnt/sdb1 you would use this flag

    lxc-create -n realtechtalk.com -t debian -- -r stretch -a amd64
    /usr/share/lxc/templates/lxc-debian: line 574: type: debootstrap: not found

    Oops, we have a debootstrap missing command error.  For Debian machines we need debootstrap:

    Try again:

    How to reset the Web Admin/GUI Username or Password in CUCM

    Oops you forgot the username or even the password and can't login to your CUCM?  As long as you can login to the CLI you can use these commands:

    Reset the username (eg. you don't recall what username you specified as the web admin GUI user!)

    utils reset_application_ui_administrator_name

    You need to reset the web admin GUI password

    utils reset_application_ui_administrator_password

    Network will not work after changing VM NIC Mac Address:

    I have even mounted the image using: guestmount -a cucm12-publisher.img -m /dev/sda1 mount

    I have tried the below but it still not work.  Neither does setting the IP manually or by DHCP or by setting the network up and down.

    Then I deleted /etc/udev.d/rules.d/70-persistent-net.rules since it has the old MAC address.  It then gets regenerated by udev properly upon reboot.  You could change the file and edit the MAC but that breaks things for SELINUX

    # line, and change only the value of the NAME= key.

    # PCI device 0x1af4:0x1000 (virtio-pci)

  • SSH persistent and automatic login script for proxy


    #!/bin/bash

    sshcommand="ssh -N -R 20000:localhost:22 user@8.8.8.8"
    result=`ps aux|grep $sshcommand"|grep -v grep`

    if [ -z "$result" ]; then
       echo "we are going to connect"
       $sshcommand
    else
      echo "we are already connected"
    fi

    This is a handy script you can use and then add it to cron.

    Save it as proxy.sh and add this to your cron (this will check every minute and start the SSH proxy if it is not running):

    crontab -e

    *1/ * * * * /home/user/proxy.sh


    Server Side

    What happens is that the connection breaks for some reason.  Now your client will reconnect but it won't be able to listen on the port possibly because the server side still has the stale SSH process listening on your proxy port.

    We need a script to check that the proxy port is open and SSH is accessible.  If the port is open but we don't get served SSH then we will find the process for the port and kill it so a new, working connection can be made.

    Put this into a cron as "checkproxy.sh":

    #!/bin/bash

    proxyport=20000
    checkstatus=`nc -w 3 localhost $proxyport|grep -i openssh`

    if [[ $checkstatus == *OpenSSH* ]]; then
      echo "OK proxy is up and working"
    else
      # find the related sshd process
      pid=`netstat -anptu|grep $proxyport|grep sshd|awk {'print $7'}|cut -d "/" -f 1`
      echo "it is not working let's kill the process so the client can reconnect"
      kill $pid
    fi
     


  • SSH proxy/command in the background or from cron script


    If you have an SSH proxy that you need to run automatically from cron you will need it in the background to work.

    ssh -N -D 22000 user@domain.com

    Basically the -N let's it continue running in the background.


  • ssh reverse proxy to enable remote access behind a LAN and firewall


    So say you are behind a typical NAT/LAN setup whether at home, work or while travelling.  What if you have a computer or server that you need to connect to from the outside?

    Yes you could use a VPN but a quick and dirty, temporary and secure way is to use SSH's Reverse Tunneling Proxy feature.

    Requirements

    On the remote ssh server host you need the GatewayPorts option enabled in sshd_config (be sure to restart sshd after making the change)

    Your sshd_config needs this:

    GatewayPorts yes
     

    On the client / machine that is behind the firewall run the SSH command

    ssh -R 33000:localhost:3389 username@remoteip

    33000 means when we connect to remoteip:33000 we will be connected to port 3389 o the localhost.

    Now we can change the localhost to another IP on our LAN if we wanted to.

    Now if we connected to remote ip's 3389 we could connect to RDP even though the machine is firewall'd (this works even if all ports are closed and nothing is forwarded to your machine since the ssh -R reverse proxy command is what handles our inbound connections through the remoteip).


  • How To Use Letsencrypt SSL/TLS Encryption to Create Certificates without installing on the target machine


    For some reason, perhaps you don't want to run a daemon or let Letsencrypt have access to your production server.

    There is a way to use it like a normal CSR/CA setup in manual mode.

    ./letsencrypt-auto certonly --manual -d realtechtalk.com - www.realtechtalk.com
     

    Eventually you will get prompted to create a certain path and file with certain data:

    Create a file containing just this data:

    CasdfasfadsfsadfsdafsdafdsafdsafdsuKVQ

    And make it available on your web server at this URL:

    http://realtechtalk.com.well-known/acme-challenge/C-asdfasfdsafdsQciE_IQ8

    - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    Press Enter to Continue

    #edit this script to suite your vhost path and then run it:

    #!/bin/bash

    fullurl=$1
    data=$2

    if [ -z $fullurl ] || [ -z $data ]; then
      echo "Usage $0 http://url/.well-known/file data"
      exit 1
    fi

    #replace http://www
    if [[ $fullurl == http://www.* ]]; then
     path=`echo $fullurl|sed s#"http://www."##g|cut -f 1 -d "/"`
     #echo "path with www"
    else
     path=`echo $fullurl|sed s#"http://"##g|cut -f 1 -d "/"`
    fi
    fullpath=/www/vhosts/$path/httpdocs/
    createpath=`echo $fullurl|sed s#"http://"##g|cut -d "/" -f 4`

    # put your main vhost path here
    cd /www/vhosts/$path/httpdocs
    mkdir -p .well-known/acme-challenge
    echo "$data" > .well-known/acme-challenge/$createpath

    Then run the script:

    the first argument is the URL they wanted you to create the second is the data they want in the file.

    ./letsencrypt-realtechtalk.com http://realtechtalk.com.well-known/acme-challenge/C-asdfasfdsafdsQciE_IQ8
    CasdfasfadsfsadfsdafsdafdsafdsafdsuKVQ

    Then hit enter on the letsencrypt screen

  • bash if statement with wildcard string matching


    In this case if fullurl started with http://www. then it is a match

    Note that you CANNOT put quotes around it or it becomes a literal match which will not work as intended in the bash script example below.

    if [[ $fullurl == http://www.* ]]; then
       echo "do something"
    fi

    Another example say we want to delete every file or dir in a path except sometihng that starts with "hellothere":

    for file in `ls -1`; do
      if [[ $file == hellothere* ]]; then
        echo "oops electrum $file - do nothing"
      else
        rm -rf $file
      fi
    done
     

    We could also change the if above to match "hellothere" at the end or in the middle eg. $file== *hellothere*


  • Cisco Router Setup Guide and Tutorial Howto With Commands and Examples


    In most of the Cisco router IOS I find the ports like ge0/0 ge0/1 and ge0/2 or whatever your ports are down.  They will not even give you a link light.  So one of the first tasks should be getting the port you are working with up.

    In my case the first goal is often connectivity with the LAN and WAN.

    LAN = your local area network (eg. in the office/home )

    WAN = your ISP/public internet (eg. fiber/cable/dsl/ethernet).

    In these examples I assume we have 3 x gigabit ethernet interfaces.

    GE0/0, GE0/1, GE0/2

    GE0/0 plugged into the WAN / public internet

    GE0/1 lugged into the LAN / local net

    Login and bring up GE0/1 (your LAN port) which should be plugged into another switch

    #you can also use int gi0/1 for short

    Router>enable
    Router#conf t
    Router(config)#interface gigabitethernet0/1
    Router(config-if)#no shutdown
     

    *Mar 25 20:39:21.151: %LINK-3-UPDOWN: Interface GigabitEthernet0/1, changed state to down
    *Mar 25 20:39:23.695: %LINK-3-UPDOWN: Interface GigabitEthernet0/1, changed state to up
    *Mar 25 20:39:24.695: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/1, changed state to up
     

    Assign an IP address to an interface:

    Router(config-if)#int gi0/1
    Router(config-if)#ip address 192.168.1.1 255.255.255.0

    You should be able to ping this IP from devices connected to the switch provided that they are on the same VLAN as the port that you have plugged into on the switch.  You should also be able to ping other devices on your LAN from the router interface successfully.

    Create a DHCP Pool for this network:

    #let's run our own DNS
    R1(config)#ip dns server
    R1(config)#ip dhcp pool nat
    R1(dhcp-config)#default-router 192.168.1.1
    R1(dhcp-config)#network 192.168.1.0 255.255.255.0
    #specify ourselves/own DNS as the DNS server for clients to use
    R1(dhcp-config)#dns-server 192.168.1.1
    #go back to our main config and make sure we exclude the router address
    R1(config)#ip dhcp excluded-address 192.168.1.1

    The error above where you do not get a password prompt from SSH is caused by your client and also Cisco.  You see if you check the logs, it will often try to send your RSA key to authenticate, when that fails it also says your password failed (even though it never prompted you!).  I am thinking it is a bug.  If you have client-side SSH keys you need to make sure you DO NOT send them by using this option on the client side:

    ssh -o PubkeyAuthentication=no user@10.10.10.1

    debug ip ssh

    Revised More Efficient/Better Version:

    I like this version better becaues it uses the same data from netstat because even a few seconds later the table may have changed and the connection will no longer be visible.  This way is also quicker and more efficient since there are no more multiple calls to the netstat binary.

    rawoutput=`netstat -nt`
    ipoutput=`echo "$rawoutput"|awk '{ print $5 }'|cut -d ":" -f 1|tail -n +3|sort|uniq`

     for ip in $ipoutput; do
         echo $ip;
         sourceconn=`echo "$rawoutput"|grep -i $ip|awk '{print $4}'|sort|uniq`
         whois=`whois $ip|grep -Ei "netname|range:|route:|cidr:"`
         if [ -z "$whois" ]; then
             whois=`whois $ip|grep -vE "^$|^#|^$|^["`
         fi

         echo -e "$whoisn$sourceconnn---------------------------"
      done
     

    More Advanced/Slower Version

    The above version doesn't always capture the name of the network, here is a more advanced script that is more inclusive and also shows the IP ranges associated with the IP and also the IPs and ports it is actually connected to.

     

     for ip in `netstat -nt|awk '{ print $5 }'|cut -d ":" -f 1|tail -n +3|sort|uniq`; do
         echo $ip;
         sourceconn=`netstat -nt|grep -i $ip|awk '{print $4}'|sort|uniq`

    To enable global "Switch DHCP Snooping":

    Switch(config)#ip dhcp snooping

    To enable DHCP snoop debugging

    Note this only works IF the global dhcp snooping is enabled

    debug ip dhcp snooping packet

    To disable the DHCP debugging:

    no debug ip dhcp snooping packet

    Enable Port As Trusted:

    You cannot broadcast DHCP unless the port is trusted so here's how you enable trust on a port (it does not work on a vlan I suppose for security reasons):

    Switch(config-if)#int fa0/1
    Switch(config-if)#ip dhcp snooping trust

    Enable Snooping on VLAN:

    Switch(config)#
    Switch(config)#ip dhcp snooping vlan 1

    Allow Untrusted Port:

    int fa0/3

    ip dhcp snooping information option allow-untrusted

    Disable Option 82

    If the relay or destination DHCP server doesn't support Option 82 Information it will break your DHCP and you will NOT get an IP/lease.

    So disable Option 82 unless you are sure your network supports it:

    Switch(config)#no ip dhcp snooping information option

    Configure interfaces

    100M Ethernet is normally known as fa0

    So for port 1 you would use fa0/1

    int fa0/1

    or

    int fastethernet0/1

    1Gig Ethernet known as gigabitethernet or gi0

    int gigabitethernet0/1

    or

    int gi0/1

    You can configure vlans in the same way:

    int vlan 1

    Working with a range of ports (example of ports 1-12)

    int range fa0/1-12

    Enable Port(s)

    int fa0/1

    no shutdown

    The no in front of shutdown means turn on the port (the opposite or !)

    How to Assign ports to vlan

    #how to assign ports to vlan in this case it is ports 1-24 and they are being assigned to vlan 1

    Switch(config)#int range fa0/1-24
    Switch(config-if-range)#switchport access vlan 1

    Port Security

     

    Maximum MAC addresses/devices

    Where 8 below  is the maximum number of MAC's

    rtt(config)#int fa0/3                         
    rtt(config-if)#switchport port-security maximum 8

    To Disable MAC Limit

    rtt(config-if)#no switchport port-security maximum

    How To Disable Port Security On A Port

    no switchport port-security
    no switchport port-security violation protect
    no switchport port-security mac-address sticky
    no switchport mode access

    BPDU Guard

    This can be the source of a lot of pain for end users and network admins.  To understand this, first let's talk about STP (Spanning Tree Protocol) which is designed to prevent routing loops that would otherwise kill a network.  A routing loop could be something as simple as an ethernet cable that has both ends plugged into the same switch.

    STP works by exchanging BPDU (Bridge Protocol Data Units) which are multicast messages sent out and contain info like the source MAC, switch ID, originating switch port, switch port priority.  It then uses an algorithm based on the BPDU information to create an STA (Spanning Tree Algorithm) at the layer 2 level and will shut down a port if it is creating a loop.

    Now BPDU Guard in the world of Cisco just means that if it receives a BPDU it will shutdown the port in errdisable.

    I say this is good in terms of keeping a network secure and running well, but a pain for end users who need to run a managed switch and for network admins who were unaware that BPDU was enabled.

    Check a port's settings and you may see this:

    rtt#show run int gi0/1
    Building configuration...

    Current configuration : 335 bytes

    How to assign IP to VLAN

    Choose your interface eg vlan 777

    Where below 10.25.20.2 is the IP and the netmask is 255.255.255.0

    Switch(config-if)#ip address 10.25.20.2 255.255.255.0

    Assign the default gateway:

    Switch(config-if)#ip default-gateway 10.25.20.1

    How To Set Administrative "enable" mode Password

    Switch(config)#enable password realtechtalk.com
     

    DHCP Server Creation for VLAN

    Create VLAN and assign IP 10.25.2.2 and DFGW 10.25.2.1

    switch(config-if)#int vlan 1800                     
    switch(config-if)#ip address 10.25.2.2 255.255.255.0
    switch(config-if)#ip default-gateway 10.25.2.1

    #you could add Option 150 if this VLAN is for phones and you have a CUCM Server (specify the CUCM server IP)

    switch(dhcp-config)#option 150 ip 10.25.2.8

    Create DHCP Pool for VLAN 1800 range 10.25.2.0

    switch(config)#ip dhcp pool Update
    switch(dhcp-config)#network 10.25.2.0 255.255.255.0
    switch(dhcp-config)#dns-server 8.8.8.8 4.2.2.1
    switch(dhcp-config)#default-router 10.25.2.1

    Exclude Relevant Addresses

    switch(config)#ip dhcp excluded-address 10.25.2.1 10.25.2.2
     

    Troubleshooting

    Why can't I ping or connect to my VLAN IP?

    • Make sure the VLAN that has the IP is assigned to a port
    • Make sure the IP address is correct and it has the appropriate default gateway if necessary
    • Make sure your client side machine has an IP on that subnet AND that you have a route to it through the right adapter (eg. in Linux  ip route add 10.10.25.0/24 dev eth0)*Remember to specify the /24 or whatever mask you desire and the right device.
    • Is the port and VLAN in a noshut state?

  • How To Boot Cisco CUCM UCSInstall 8.6, 10, 11 and 12 on KVM/Proxmox


    The key thing is that you must use a "machine" id of "pc-1.3" or it will say your hardware is not supported.

    Additionally you MUST use a virtio disk or you will get a ks_pre.sh error as soon as the install starts (a look at logs will show it can't find a disk).  This is funny because even though the OS finds the disk and an fdisk -l shows it, it looks like the script looks for a /dev/vda device (virtio) and nothing else, so if you didn't use Virtio as your disk and you have a /dev/sda it won't work.

    In Promxox you will have to edit your config file like this:

    bootdisk: sata0
    cores: 12

  • VBOX VirtualBox How To Import Raw .img Disk File


    What you need to do if you have taken a dd or real raw image dump of a hard disk:

    VBoxManage convertdd windows2019-eval-template.img windows2019.vdi --format VDI

    The .img is the raw dd dump and the .vdi is the output file.

    --format VDI specifies to output to .vdi format

    If you are in a pinch you can always use qemu-kvm binary and manually specify the .img as your disk and it will just work.

     

    *Even the above didn't work for some reason with VBOX

    VBoxManage convertdd windows2019-eval-template.img windows2019.vdi --format VDI
    Converting from raw image file="windows2019-eval-template.img" to file="windows2019.vdi"...
    Creating dynamic image with size 21474836480 bytes (20480MB)...

    *Note if you are mounting the .vdi over SMB or SSHFS you may still get the below error (sometimes it only works well locally)

    VD: error
    VERR_NET_OPERATION_NOT_SUPPORTED

    What doesn't work if you have taken a raw image / dd of an LVM or Physical Hard Disk:

    I tried the raw image and you get:

    Could not get the storage format of the medium (VERR_NOT_SUPPORTED).

    Then I converted it to qcow2:

    qemu-img convert -f raw -O qcow2 windows2019-eval-template.img windows2019-eval-template.qcow2

    But I still got the same error.

    So then I tried to convert it to .vdi:

    qemu-img convert -f raw -O vdi windows2019-eval-template.img windows2019-eval-template.vdi


    VD: error
    VERR_NET_OPERATION_NOT_SUPPORTED

    The original partition of the .img looks like this:

     

    fdisk -l windows2019-eval-template.img

    Disk windows2019-eval-template.img: 21.5 GB, 21474836480 bytes

    As we can see the tap devices went disabled which makes sense BUT they didn't come back so all VMs now have no network connection (the equivalent of basically unplugging the cable from the server):

  • Linux ln symlink how to update existing symbolic link


    ln -s --force newfile.jpg existingsymlink.jpg
     

    All you do is use the --force flag to force/update the existing one.

    The above modifies a symlink called "existingsymlink.jpg" and points it to "newfile.jpg" as the source.


  • Ubuntu 18.04 / Linux Mint 19.1 Cannot Type or Login - solution


    It was broken because of this package for xorg I installed:

    xserver-xorg-core-hwe-18.04

    Just remove it even if you have to chroot from a live USB/CD:

    sudo apt-get remove xserver-xorg-core-hwe-18.04


  • LUKS Hard Drive Encryption on Linux Mint Ubuntu Debian etc how to mount encrypted hard drive


    The key thing here is to know the actual partition that is encrypted.

    Often in Linux Mint's installer that ends up being partition 5 or /dev/sda5

    sudo cryptsetup luksOpen /dev/sda5 anynamehere

    You will then be prompted for your irrecoverable passphrase:

    Enter passphrase for /dev/sda5:

    If all goes well it won't say anything further.  If it says ""No key available with this passphrase." it means you have entered the wrong password.

    How to mount

    The above command will create a device based on the third argument that you passed to cryptsetup (anynamehere) in the above example.

    So you would see i/dev/mapper/anynamehere

    From there just go ahead and mount it (assuming it is not using LVM-read on if you are).

    mount /dev/mapper/anynamehere /mnt/crypteddisk

    Chroot

    To make it more practical perhaps you are trying to modify or fix your OS.

    From here if we were using many OS's we would then do an "lvscan".  It will then show us the LVM volumes and you can then mount the vg-root to /mnt

    You can then do something like this:

    mount /dev/vgname/vg-root /mnt

    #use the bash script to mount /dev /proc and /sys to your /mnt (chroot) root dir so stuff works when you chroot

    for mount in dev proc sys; do

    mount -o bind /$mount /mnt/$mount

    done

    #now let's chroot in!

    chroot /mnt


  • How to use nmap locate other machines/computers/servers on your network using nmap


    A lot of people think arp wil do it but the arp table will only show devices you have communicated with.

    Using nmap is a quick and simple way to scan a range to find a machine you may not know the IP for:

    eg:

    nmap -sP 10.1.5.0/24

    Just change the above to your subnet


  • Linux Mint 18.2 Create Config File To Start Application Upon Login


    This is not about systemd/systemctl and not about "onboot" so there's no rc.local trick here but it's the GUI/Gnome etc when a user logs in that a command is launched.

    Put this in your home dir
     

    The .config/autostart directory is where Linux Mint/Ubuntu checks for autostart application config files


    mkdir -p ~/.config/autostart

    Create a new entry/file that starts an application:


    vi realtechtalk.com.desktop

    The name can be anything but must have  ".desktop" as the extension.

    [Desktop Entry]
    Type=Application
    Exec=/usr/bin/firefox http://realtechtalk.com
    Hidden=false
    X-MATE-Autostart-enabled=true
    Name[en_US]=firefox
    Name=firefox
    Comment[en_US]=Visit realtechtalk.com!
    Comment=

     

    The key point from above is the "Exec" variable and Name variable.  Change exec to what you want to execute and change the name to something meaningful

    For most of these machines you just have to power the unit on while holding the "Del" key and you'll enter the BIOS. 


  • sudoers file in /etc warning about comments/includes!


    If you see this in /etc/sudoers it is NOT a comment but an include.

    #includedir /etc/sudoers.d
     

    For example in Linux mint sudoers.d contains the following files:

    casper  mintupdate  README
     

    casper for example contains the following sudoers line:

    mint  ALL=(ALL) NOPASSWD: ALL
     

    So if you are messing around with sudoers or creating a new file understand that #includedir is absolutely not a comment and may be critical to properly functioning sudo functionality for your machine or user.

    Of course this is contrary to most Unix based config files where often a pound # is a comment.


  • Centos 7 Reallocate logical volume space to another


    Do you hate how Centos 7 defaults to allocating most of your valuable space to /home even though it is a production server?

    Here is a quick guide on how to take back that space live, while online (of course make sure you have backups just in case something goes wrong!):

    First we will reduce our home dir by 100G:

    lvreduce -L -100G /dev/mapper/centos-home
      WARNING: Reducing active and open logical volume to <5.12 GiB.
      THIS MAY DESTROY YOUR DATA (filesystem etc.)
    Do you really want to reduce centos/home? [y/n]: y
      Size of logical volume centos/home changed from <105.12 GiB (26910 extents) to <5.12 GiB (1310 extents).
      Logical volume centos/home successfully resized.
     

    Now let's give it back to /root:


    lvextend -l 100%FREE /dev/centos/root
      Size of logical volume centos/root changed from 50.00 GiB (12800 extents) to 100.00 GiB (25601 extents).
      Logical volume centos/root successfully resized.

    OK but now what does our filesystem magically know what we did with the LV/logical volume?  No


    [root@disc livefilesystem]# df -h
    Filesystem               Size  Used Avail Use% Mounted on
    /dev/mapper/centos-root   50G   35G   16G  70% /

    tmpfs                    379M     0  379M   0% /run/user/0

    Maybe we could just remount it? No



    [root@disc livefilesystem]# mount -o remount /
    [root@disc livefilesystem]# df -h
    Filesystem               Size  Used Avail Use% Mounted on
    /dev/mapper/centos-root   50G   35G   16G  70% /

    How do we resize the filesystem?  xfs_growfs of course!


    xfs_growfs /dev/mapper/centos-root
    meta-data=/dev/mapper/centos-root isize=512    agcount=4, agsize=3276800 blks
             =                       sectsz=512   attr=2, projid32bit=1

    realtime =none                   extsz=4096   blocks=0, rtextents=0
    data blocks changed from 13107200 to 26215424

    Now it's all good!


    [root@disc livefilesystem]# df -h

  • SSH error cannot Forward or Listen "bind: Cannot assign requested address"


    debug1: Local connections to LOCALHOST:18006 forwarded to remote address 192.168.1.93:8006
    debug1: Local forwarding listening on 127.0.0.1 port 18006.
    debug1: channel 0: new [port listener]
    debug1: Local forwarding listening on ::1 port 18006.
    bind: Cannot assign requested address

    What we are seeing is that we can't listen on an IPV6 address of ::1.  We need to tell SSH to stop using IPV6 so we'll edit ssh_config to take care of this issue. 

    Solution:


    sudo vi /etc/ssh/ssh_config

     

    Set this:


    Host *
    AddressFamily inet
     

    Formerly the "inet" would say any which means it would be IPV6 too but we can't have that since it breaks out forwarding!

    The "inet" in address family disables IPV6 because we can see in the SSH verbose output earlier that it was trying to listen on ::1 (which is an IPV6 address).  This breaks if you don't have IPV6 enabled in your OS which is why we get the message from bind.


  • X11 SSH Linux Forwarding Error


    Jan 30 17:16:10 localhost sshd[25385]: error: Failed to allocate internet-domain X11 display socket.
     

    The solution for me on the server side was the following in sshd_config:

    AddressFamily inet

    *Remember to restart sshd and also reconnect from the client side.
     

    I had all the normal X11 settings on the server but it just stopped working for me randomly:

    X11Forwarding yes
    X11DisplayOffset 10

    I am thinking this is a client side error in the sense that perhaps newer SSH clients cause this bug because things were working fine for months and nothing changed on the server side.

    This happened on Linux Mint/Ubuntu/Debian based machines.

    Choose your domain/computer and then navigate like below and create a new menu entry for IE11 or whatever your version is.  Don't be worried if the highest version is IE10 it means that it applies to IE10 AND above.

     

     

     

     

     

    Make your changes

    After that close the GPME and the settings will apply to users once they login again.

    Of course you can use GPME for other apps, settings etc.. so customize as you need.

     

    Don't forget to run "gpupdate" on existing clients or they may not get the GP changes you've made (eg. meaning what you did will have no effect on the user).

  • LVM How To Create Pool (dynamically allocated and not fully allocated)


    The main use I have for this is virtual servers being able to use an LVM volume but not occupying all of the space.  It saves time in deploying machines and copying them so you are only copying the space they are using (eg. 5GB / 60GB vs the full 60GB).  There are some disadvantages which is mainly the fact that thin pools by their nature allow you to "overallocate" disk space which is that you could use more space than is available on the disk itself and corrupt your data.

    So in my opinion it is best to avoid thin pools EXCEPT if you have a testing environment you need to get up quickly or if you REALLY know what you are doing (eg. you are sure the disk space won't be overallocated or you have some other safeguards).

     

    How To Create An LVM Thin Pool

    -L = the size of the pool

    --thinpool = specifies we are creating a thin pool

    vmthinpool = the name of our thinpool

    vms = the name of the vg / volume group we are creating it on.

    lvcreate -L 500GB --thinpool vmthinpool vms
      Using default stripesize 64.00 KiB.
      Logical volume "vmthinpool" created.
     


  • VMWare Pro Workstation Nic Disconnected and No IP Using NAT


    By default VMWare Workstation often doesn't work as we would like.

    If you create a VM with a default NAT IP it won't work you will find the NIC is disconnected (even though on the VMWare side it says connected including at Power On).

    How To Solve It

    1.) Create New VMNet for NAT

    Click "Edit" -> "Virtual Network Editor"

    Click "Add Network"

    Select Network To Add "VMNet1" (or the next available name).

     

    Click on "NAT" under "Network Information"

    It should by default enable DHCP and a default range of 192.168.*.*

    and hit OK.

     

    2.) Edit your VM and assign it the VMNet you created above.

     

     

     


  • Linux How To Create A RamDisk


    size = the amount of RAM (m for megabytes)

    /mnt/ram = the mount location of the ram disk (change to the path you want it mounted to)

    mount -t tmpfs -o size=4096m tmpfs /mnt/ram/
     

    Example test in an old server:

    You can see that when reading if you don't specify bs1=M the read speeds are several times slower (eg. 450MB/s vs 2.1GB/s)

    mount -t tmpfs -o size=4096m tmpfs /mnt/ram/^C

  • Proxmox Breaks Storage/LVM Backing If Killing QEMU-IMG


    I tried to stop a qemu-img copy or clone and it broke everything. It was fine to "stop" it from the GUI but a process still persisted so I killed the relevant qemu-img and the kernel went crazy. It also may not have helped that I tried to lvremove a different volume (an unused disk). But either way it breaks LVM (you cannot even run lvdisplay) so a reboot is necessary.

  • Proxmox trying to acquire lock... TASK ERROR: can't lock file '/var/lock/qemu-server/lock-102.conf' - got timeout


    If Proxmox won't start aVM with an error like this:

    trying to acquire lock...
    TASK ERROR: can't lock file '/var/lock/qemu-server/lock-102.conf' - got timeout

    rm /var/lock/qemu-server/lock-102.conf

    Then try to restart the VM and it should be good.


  • Debian 9 SSH root password authentication failure password not working problem / solution


    In Debian a lot of times SSH disables the root user to login by password by default.  This means you will get an authentication failure as if you typed in the wrong password.

    The logs also indicate the password is wrong but what is often the case is in the config file

    Check /etc/ssh/sshd_config

    cat /etc/ssh/sshd_config|grep -i permitrootlogin

    Make sure it says:

    PermitRootLogin yes
     

    If not change it and restart SSH and it will work again.

    Enable Bridged Networking

    First of all you need a bridged NIC, see this post on how to do that.

    If you get this message it basically / usually means you have no networking eg. no NIC or it is not connected to anything.

    qemu-system-x86_64: warning: vlan 0 is not connected to host network

    Take the same qemu-system command from earlier one and add this:

    The below assumes you have a bridged tap adapter called "tap2019".  You will also need to bring the tap adapter up:

    ip link set dev tap2019 up

    qemu-system-x86_64 -m 4096 -drive file=skype.img -cdrom ~/Downloads/SfB-E-9319.0-enUS.ISO -net nic,model=virtio -net tap,ifname=tap2019,script=no,downscript=no


    You can change the model=virtio to something else like Intel's e1000.  The ifname=tap2019 is obviously going to be set to the tap device you have.

     

    Nice Script To Tie Basic QEMU-KVM Usage Together:

    tapdev=`tunctl -b`
    macaddr=`openssl rand -hex 6 | sed 's/(..)(..)(..)(..)(..)(..)/1:2:3:4:5:6/'`
    iso=/mnt/vms/iso/linuxmint-19.1-mate-64bit.iso
    drive="-drive somefile.img,if=virtio"
    ram=4096
    cores=8
    qemubin="/usr/libexec/qemu-kvm"
    vncport=5
    cdrom="-cdrom $iso"
    $qemubin -smp $cores $cdrom -boot once=d  -vnc :$vncport -m $ram $drive -net nic,macaddr=$macaddr,model=virtio -net tap,ifname=$tapdev,script=no,downscript=no&
    ifconfig $tapdev up
    #or
    #brctl addif br0 $tapdev

    # proxy arp only needed if you are not using a bridge

    # if not using a bridge you need proxy_arp AND you need to do add the route of the VMs IP to the tapdev eg. ip route add 10.10.25.20 dev tap20194
    echo 1 > /proc/sys/net/ipv4/conf/$tapdev/proxy_arp

    tapdev= name of your tap device

    tunctl -t $tapdev creates this device

    iso= path of your iso

    ram= ram in megabytes

    cores=8 how many SMP/processors the VM gets

    qemubin= the path to your qemu binary

    vncport= your port number a number of 5 means port 5905

    cdrom= the $iso is the path to the iso you specified above

    the actual execution of the script is somewhat dynamic.  For example if you don't specifiy "$drive" in the command line there won't be any hard disk (useful for livecds).  Or commenting it out as shown above achieves the same result.
     

    The "ifconfig" part actually puts up the tap device or is kind of the equivalent of plugging in a cable to the virtual NIC on the VM.

    The echo 1 to proxy_arp makes it so your tap device can broadcast and receive arp requests.  This way you can assign any IP to it and have it work.

    Now the caveat not listed here which is very important is the routing.

    You need to statically assign an IP to your VM and then add the routing (assuming you don't have a bridge which in this case brctl add if br0 $tapdev will automatically make the route work

    If you don't have a bridge then you will need to do a "ip route add yourip dev yournic"

    This will need to be done each time you start the VM or restart the host machine.

  • PHP Issues With Decoding Strange Smart Quotes And Non-Standard ASCII Characters


    When using strip_tags and html_entity_decode with PHP it often breaks and produces annoying diamonds with question marks.

    It is probably because of characters like these:

    … (looks like 3 dots but it is a single weird character).

    ’ (looks like a normal apostraphe but it is not)

    ” (looks like a normal double quote but it is not).

    An easy way to sort this out is to copy the above and search in an ASCII table to extend the functionality below.

    Basically the first array has a list of "all the bad stuff" and the second array is what to replace it with.

    <?


    function CleanupSmartQuotes($text)
        {
            $badwordchars=array(
                                chr(145), // weird apostraphe
                                chr(146), // weird apostraphe
                                chr(147), // weird quote
                                chr(148), // weird quote
                                chr(151), // weird dash
                                chr(133), // three dots
                                '&nbsp;',
                                );
            $fixedwordchars=array(
                                "'",
                                "'",
                                '&quot;',
                                '&quot;',
                                '&mdash;',
                                '...',
                                '',
                                );
            return str_replace($badwordchars,$fixedwordchars,$text);
        }

    ?>

  • iptables how to log ALL dropped incoming packets


    A lot of people just have a -j DROP to drop all unwanted traffic or traffic not explicitly allowed but there is a better solution if you want real and proper logging:

    Take an example iptables rules file

    -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
    -A INPUT -i eth1 -p icmp -j ACCEPT
    -A INPUT -i lo -j ACCEPT
    -A INPUT -i eth1 -j ACCEPT
    -N LOGGING
    -A INPUT -j LOGGING
    -A LOGGING -j LOG --log-prefix  "ipt denied: " --log-level 4
    -A LOGGING -j DROP

    Add the above in bold below your last allowed incoming traffic rule and all dropped packets can be seen in dmesg or /var/log/messages

    1. We create a new chain called "LOGGING"  -N LOGGING
    2. We are then passing all of our packets to that chain. -A INPUT -j LOGGING
    3. Log all packets that are about to dropped with prefix "ipt denied:" (of course change it how you like) -A LOGGING -j LOG --log-prefix  "ipt denied: " --log-level 4
    4. Drop all packets in the LOGGING Chain -A LOGGING -j DROP

    So in essence we change the -j DROP to the 4 lines in bold so that we have logging.

     

    Checking dmesg or /var/log/messages should show similar to the following:

    How can I log the messages to a separate file eg. /var/log/iptables.log or /var/log/iptables-dropped.log?

    The file name below can be arbitrary but it should have meaning to you.

    Note that I am searching for the string "ipt denied: " this depends on what you have set as your log prefix in the example above.

    vi /etc/rsyslog.d/10-iptables.conf

    :msg, contains, "ipt denied: " -/var/log/iptables.log
    & ~

    #note we need the "& ~" below the first line otherwise it will still send the log to where ever it would have been (eg. often /var/log/messages).
    #the & ~ means to delete


    service rsyslog restart

     

    You should now notice that /var/log/messages has nothing for iptables and that you have /var/log/iptables.log

  • DRBD Errors Caused By Physical Corruption


    In a RAID array I had a have periodically lost a drive here and there over the past several months.  I was always able to readd and resync without losing data.  However at some point it looks like some minor corruption happened and this makes DRBD unhappy.

    Using fsck did not help either.

  • mdadm: add new device failed for /dev/sdb4 as 3: Invalid argument solution


    mdadm --manage /dev/md125 -a /dev/sdb4

    mdadm --manage /dev/md125 -a /dev/sdb4

    mdadm: add new device failed for /dev/sdb4 as 3: Invalid argument



    Solution / this is the only thing that fixed it (basically do more than just zero-superblock)

    dd if=/dev/zero of=/dev/sdb4
    ^C77149+0 records in
    77149+0 records out
    39500288 bytes (40 MB) copied, 5.35553 s, 7.4 MB/s

    #success!

    mdadm --manage /dev/md125 -a /dev/sdb4
    mdadm: added /dev/sdb4
     

    The weird thing is that you can see zero-superblock was NOT enough to fix it and sometimes you have to wipe a little further than zero-superblock does and it will fix it.  I didn't find this solution anywhere so I thought I'd share it.


  • Linux named / bind how to dump, view and clear the cache!


    Do you hate it when your ISP has old cached records because of a high TTL on the DNS record of the relevant domain?  In plain English this means you often can't connect to a site or service because your ISP's DNS servers haven't gotten word of the new IP address (probably because they haven't checked).  There are also some that are notorious for ignoring TTL and not updating records for days!

    But if you are lucky and smart enough to have your own Linux based DNS server you can do the following:

    rndc dumpdb -cache

    This let's you see the cached entries by writing the bind cache to /var/named/data/cache_dump.db

    If you just want to clear your DNS cache:

    rndc flush

    The above flushes all of your DNS cache which is never a bad idea since it saves memory and increases the performance potentially.


  • Centos 6 / 7 / 8 How To Change Default nameservers in /etc/resolv.conf when using DHCP / dhclient


    First we need to create dhclient.conf if it doesn't exist or edit it:

    vi /etc/dhclient/dhclient.conf


    #add this line at the top add the IPs as commas they will be the highest priority nameservers and whatever your ISP gives you will be used after these one (good for DNS backup)

    prepend domain-name-servers 127.0.0.1,10.10.25.8;

    After you restart your network or run dhclient again you should see the contents of /etc/resolv.conf are as you expect.

    This is mainly when you are running a local router and local DNS (and usually your own local DNS is quicker and more reliable than your ISP in my experience).

     

     


  • Adobe Acrobat Reader for Linux to use and view XFA Fillable Forms


     

    The reason for not being able to read one of these dreaded/ fillable "XFA" forms is because no Linux PDF reader that I'm aware of supports them. Part of this reasoning is for security.  It is really silly, they should ban these XFA forms or at least replace the Please Wait with the non-fillable version. 

    Download Adobe Reader 9.5 for Linux from here:

    This is the solution but only so much, at least for me I was able to view the PDF and fill it but printing it produces a blank page (even print preview shows it as  blank).  I tried converting it to a normal pdf with print to file including postscript but none of that worked either.

    With that said you too can get this broken version of the Linux Adobe Acrobat version :)

    Perhaps a previous 9.5 (older version) even though the latest is from 2013 may work better?

  • Debian Linux Mint Ubuntu iptables save and restore settings automatically onboot and reboot


    First you need the "iptables-persistent" package.  This gives you an init script that loads your settings from /etc/iptables/rules.v4 and rules.v6

    When you install it, it wll save your default setings in /etc/iptables.

    sudo apt-get install iptables-persistent


  • Why SMART is not smart at all and doesn't properly predict disk errors that cause a kernel panic or crash


    Before getting into the output here is my typical experience with SMART, there is what I call a "bad disk" with pending and uncorrectable sectors that cannot be reallocated.
It has caused a kernel panic and system crash repeatedly as we can see from the logs.
But SMART says it has "PASSED" its self assessment.  SMART is still useful to me but it is more about looking at Current_Pending_Sector.
Any time I have had anything but 0 for that attribute it means the disk is bad and is unusable (eg. will cause kernel panics).
In this case even RAID doesn't help when the bad disk taints the kernel.

First let's check this disk and see what SMART thinks

  • scp: ambiguous target error and solution


    scp -rp Week09 one@10.10.5.80:"/some/remote/path/with a space/"

    Gives me an error:

    scp: ambiguous target
     

    The issue is caused by the space in the remote path which needs to be escaped like this:

    scp -rp Week09 one@10.10.5.80:"/some/remote/path/with a space/"

    Basically you add a backslash in front of each space.


  • VirtualBox How To Add iSCSI Storage using VBoxManage


    #to show all
    VBoxManage list vms

    #show ONLY running vms
    VBoxManage list runningvms


    VBoxManage storageattach test --storagectl "SATA" --port 0 --device 0 --type hdd --medium iscsi --server 192.168.1.91 --target "iqn.2018-12.local.abcrandom.target:sdb" --initiator "iqn.1982-01.ca.bla.tld:abc123" --tport 3260 --lun 1

    --server = the IP address of the iSCSI target server

    --target = the target on the iSCSI srever

    --initiator = your initiator name (eg. the equivalent of /etc/iscsi/initiator.iscsi)

    --lun 1 (or whatever LUN number

    Troubleshooting

    If the disk creates successfully but VBox says it is inacessible it means you have probably specified something wrong in the flags above.  Eg. a typo in your target, initiator, forgetting your LUN

  • iSCSI on Centos 7 Configuration and Setup Guide for Initiator and Target


    initiator = client

    target = server

    These are the first concepts you should understand which is that in iscsi essentially the "initiator" is the client and the "target" is the server.

    iSCSI is derived from the old fashioned SCSI that us oldtimers grew to love.  The "i" stands for Internet and the SCSI stands for "Small Computers Systems Interface" (SCSI).

    iSCSI Target (Server) Setup

    targetcli is the package that creates the iSCSI server and allows you to export your devices. 

    yum -y install targetcli

    Created block storage object areebsfault using /dev/sdb.

    Create our target

    The "iqn" must go first and then year-time and then local and finally the "host name" and after the colon the target name "sdb".  IQN= iSCSI Qualified Name

    • iqn
    • Date (1982-01)
    • Reversed domain name of the authority (eg. target.abcrandom.local) becomes local.abcrandom.target
    • Optional “:” that prefixes a storage target name specified by the naming authority

     

    cd /iscsi

    /iscsi> create iqn.2018-12.local.abcrandom.target:sdb
    Created target iqn.2018-12.local.abcrandom.target:sdb.
    Created TPG 1.

    2. Listening on the wrong IP or port in your portal.
    3. Specifying the target instead of the initiator name/ACL name.
    4. Not creating an LUN
    5. Mixing up different target names with the wrong initiator name.
    6. The client side is using the wrong initiator name (often a random generated one by the OS).

    How To

    Login To All Targets

    iscsiadm -m node -l

    Login To Specific Target

    iscsiadm -m node -l -T iqn.target.name:bla

    Delete your iscsi target

    /iscsi> cd /iscsi/
    /iscsi> delete iqn.2016-06.localb.a.bla:123
    Deleted Target iqn.2016-06.localb.a.bla:123.

    Disconnect your client from a target

    iscsiadm -m node --logout -T iqn.2018-12.local.abcrandom.target:sdb
    Logging out of session [sid: 1, target: iqn.2018-12.local.abcrandom.target:sdb, portal: 192.168.1.91,3260]
    Logout of [sid: 1, target: iqn.2018-12.local.abcrandom.target:sdb, portal: 192.168.1.91,3260] successful.
     

    Disconnect from ALL targets

    iscsiadm -m node --logout all
    Logging out of session [sid: 2, target: iqn.2018-12.local.abcrandom.target:sdb, portal: 192.168.1.91,3260]
    Logout of [sid: 2, target: iqn.2018-12.local.abcrandom.target:sdb, portal: 192.168.1.91,3260] successful.
     


  • Python and BeautifulSoup4's BS4's Decompose Method To Remove Unwanted Inner Tags


    <div class="c-shca-icon-item__body-name">

        < a href="/Products/MX72244">
            < span class="c-shca-icon-item__body-name-brand">

                ADATA
                < / span>
                    XPG SX8200 PCI - E 3.0 x4 M .2 NVMe SSD, 480 GB
                    < / a>


    The problem in the html above is that there is a "span" inside the "a" and this is unusual except for a few products with ADATA.
    Otherwise it would print out ADATA with the other product information "XPG SX8200 PCI - E 3.0 x4 M .2 NVMe SSD, 480 GB".  So we just want the product info and not the ADATA inside span.

    The solution is to use beautifulsoup's "decompose method below".



        hddname = prices.find("div", {"class": "c-shca-icon-item__body-name"})
        hddname=hddname.find("a")
        hddname.span.decompose()
        hddname=hddname.get_text().strip()

     

    Once we have the "a" tag contents which contain a "span inside".  We just use the decompose() method.

    The format is as follows

    soupname.tagname.decompose()


  • httpd AH00534: httpd: Configuration error: No MPM loaded. solution


    httpd
    AH00534: httpd: Configuration error: No MPM loaded.

    Simple Solution (assuming you don't have this line in httpd.conf aleady:


    echo "Include conf.modules.d/*.conf" >>  /etc/httpd/conf/httpd.conf

     


  • bash script to remove modules from httpd.conf that are not actually installed


    confmodules=`cat /etc/httpd/conf/httpd.conf |grep -v ^#|grep  "modules/"|awk '{print $3}'|cut -d "/" -f 2`

    for module in $confmodules; do
      echo "module=$module"
      if [ ! -f /etc/httpd/modules/$module ]; then
        linenum=`awk /"$module/{ print NR; exit}" /etc/httpd/conf/httpd.conf`
        sed -i "$linenum"s/.*// /etc/httpd/conf/httpd.conf
        echo "hey we don't have this $module in /etc/httpd/modules"
      fi
    done

    Basically the script checks all of the modules your httpd.conf tries to load.  Then it checks if the file actually exists in /etc/httpd/modules/ and if it doesn't it edits httpd.conf by removing the relevant line for the module that doesn't exist.
