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.AMD Set Fan Speed and Other Powerplay Memory/CPU Timings with a Linux script
You can do other things but this particular script is just to set all AMD cards to 80% fan speed (remember this script needs to applied everytime you reboot). You could set it is a cron or just throw it into /etc/rc.local
basepath=/sys/class/drm
for hwmon in `ls -1 /sys/class/drm|grep card[0-99]$`; do
echo card=$hwmon;
hwmonname=`ls $basepath/$hwmon/device/hwmon|grep hwmon[0-99]`
hwmonpath=$basepath/$hwmon/device/hwmon/$hwmonname
echo "echo 1 > $hwmonpath/pwm1_enable"
echo "echo 205 > $hwmonpath/pwm1"
echo 1 > $hwmonpath/pwm1_enable
echo 205 > $hwmonpath/pwm1
done
The way it works is as follows:
The card power play settings are located in:
/sys/class/drm/cardNumber/device/hwmon/hwmonNumber
The card number is also the same order that you'll find in say Claymore and the hwmon number is usually 1 less than your card number. So as you can see below card4's hwmon path is hwmon3.
In the script I account for that just in case it may be different though.
cat /sys/class/drm/card4/device/hwmon/hwmon3/pwm1_enable
2
#enable pwm (if the value is not 1 it is not enabled so setting the fan speed would have no effect)
echo 1 > /sys/class/drm/card4/device/hwmon/hwmon3/pwm1_enable
The parameters for fan speed are a percentage or number out of max 255. So 80% would be the number 205 (it also seems to round to the nearest 5% I believe)
cat /sys/class/drm/card4/device/hwmon/hwmon3/pwm1_max
255
cat /sys/class/drm/card4/device/hwmon/hwmon3/pwm1_min
0
# 210/255 is about 82% fan speed (this still resulted in 80% actual fan speed)
echo "210" > /sys/class/drm/card4/device/hwmon/hwmon3/pwm1
The results of higher fan speeds
In one of my test rigs see that on some cards the temperature reduced by about 14C degrees!
Before:
ETH: GPU0 t=72C fan=64%, GPU1 t=72C fan=63%, GPU2 t=69C fan=23%, GPU3 t=84C fan=0%, GPU4 t=69C fan=27%
After:
ETH: GPU0 30.457 Mh/s, GPU1 30.455 Mh/s, GPU2 29.473 Mh/s, GPU3 29.498 Mh/s, GPU4 29.484 Mh/s
GPU0 t=65C fan=80%, GPU1 t=71C fan=80%, GPU2 t=55C fan=80%, GPU3 t=57C fan=80%, GPU4 t=55C fan=80%

genisoimage errors with long filenames and deep directory structures
You'll have to violate the iso9660 standards but it is necessary if you want to preserve your filesystem and filenames and shouldn't be an issue as long as you are using a modern OS like Linux.
genisoimage -o Backup-Myfiles.iso -r -J -joliet-long /some/path/
You will get errors like below (even enabling joliet-long didn't help)
genisoimage: Error: /some/filename.pdf have the same Joliet name
Joliet tree sort failed. The -joliet-long switch may help you.
#the best way
genisoimage -o /tmp/Backup-Myfiles2.iso -U -iso-level 4 -R /source/dir
This was the only way I could get unmodified long file names and VERY deep directories onto the iso image as original otherwise they get renamed and truncated which breaks a lot of things and makes it confusing. But be warned this breaks the iso9660 standard so many OS's especially Windows may not be able to read it.
==========
#this fixes it
-R is for Rock Ridge and allows for more than 8 deep folders
-U allows for untranslated filenames
genisoimage -o /tmp/Backup-Myfiles.iso -R -U .
#with an exclude
genisoimage -o /tmp/Backup-Myfiles.iso -R -U -m WebSites/blabla .
Warning: creating filesystem that does not conform to ISO-9660.
I: -input-charset not specified, using utf-8 (detected in locale settings)
#the -m causes a shrink error unless you put it earlier
genisoimage: File 'blank.html' did shrink.
Files must not be changed while genisoimage runs!
genisoimage -m WebSites/blabla -o /tmp/Backup-Myfiles.iso -R -U .

Once you have cpqsetup you can use the binary for other BIOS updates. For example if you can only find the Windows .exe BIOS update you can extract the BIOS file and replace the original file above.
You can use the Windows BIOS file by unzipping the .exe and then copying the actual firmware to the name of the old file from an older Linux flash download (it uses the new file that you give the old name):

var/tmp is out of space the same as tmpfs
#this normally happens when Proxmox first uploads it to a place in /tmp on your / filesystem and if you have used a small HDD for testing it's easy for a simple ISO upload to fail for this reason. You'll have to wget directly to the main filesystem or datastore with more space.
Cannot install moodle
After starting the install it stalls here:
admin/index.php?cache=0&agreelicense=1&confirmrelease=1&lang=en
If you manually refresh you get a Plugins check screen:
Installation
System
Moodle second step fails just blank screen:
https://domain.la/user/editadvanced.php?id=2
Solution: give up and choose something else it shouldn't be this hard to just install this moodle software!
MySQL change for Antelope format to Barracuda error solution
Your database uses Antelope as the file format. Full UTF-8 support in MySQL and MariaDB requires the Barracuda file format. Please switch to the Barracuda file format. See the documentation MySQL full unicode support for details.
In /etc/my.cnf under [mysqld]
180827 21:43:14 InnoDB: 5.5.59 started; log sequence number 1589339
180827 21:43:14 [ERROR] /usr/libexec/mysqld: unknown variable 'db_file_format=Barracuda'
#instead set this:
innodb_file_format=Barracuda
You will also need to run mysql_upgrade after changing the format and restarting mysql:
mysql_upgrade -u root -p

default 0.0.0.0 192.168.1.1 vmk0
Have you set internal IPs in VMWare and cannot ping between them on servers? It is probably because you are using an older than 6.5 version of VMWare's switch without MAC learning. To fix it you'll need to enable Promiscuous mode on the port group or change the software version ot 6.5 which has MAC learning and will make things work fine again.

To apply it properly you may need to reboot after the above
vi error solution E166: Can't open linked file for writing
This is not so much of a vi error as it is a physical filesystem error in the sense that the file you are trying to write to is a symlink and the destination doesn't exist or for some other reason is inacessible.
So vi is tellng you "you're writing to a symlinked file and the file the symlink points to cannot be written to". This is especially highlighted byt he fact that if you are using wq! to write and you still get the error.
Supermicro IPMI / KVM / BMC Remote Console Screen Resizing Issue - Window Cut Off Solution
It could just be my specific Java but other KVM/IP works ok on my machine but with Supermicro's IPMI for some reason the console window doesn't resize and even putting it in full screen leaves the window cut off as shown below:
As you can see above the screen is cut off you can't see the "I agree" on the right side.
The window resize option is on and it is clearly not working properly. Even choosing full screen doesn't change anything.
Solution - Here's how you can fix it with the Macro option:
- Macro Menu/Settings and click the option for "Hold Left Alt Key"
- Then click and hold and the mouse pointer becomes a hand.
- You can then drag to the right to expose what is cut off or whereever else you need to see.
- After you've moved the screen to where you need and want to click something make sure you disable the "Hold Left Alt Key" in macro or you won't be able to click or interact with anything.
See the example below after using the process above:
Linux bash shell doesn't show username, hostname or current path fix solution
Usually this is because when you created your user you added a user but didn't create their home directory and/or for some reason your .bashrc and .bash_profile in ~ (home) is broken/missing.
In your home just create the following files with the following content to solve it:
.bashrc and .bash_profile.
To apply it just relogin/start a new bash session
# .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
# 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

zenity popup messages, windows, dialogs, error messages calendars and more howto on Gnome Linux including Ubuntu, Linux Mint, Centos and more
zenity is a nice utility as part of the gnome window manager that allows you to script from bash and retrieve the input from the user. It could also be helpful in just notifying a user when they login with a popup window.
I'll give an overview of what's available with zenity:
Application Options: --calendar Display calendar dialog --entry Display text entry dialog --error Display error dialog --info Display info dialog --file-selection Display file selection dialog --list Display list dialog --notification Display notification --progress Display progress indication dialog --question Display question dialog --warning Display warning dialog --scale Display scale dialog --text-info Display text information dialog --color-selection Display color selection dialog --password Display password dialog --forms Display forms dialog --display=DISPLAY X display to use
A few quick examples:
Note you can even use zenity remotely from an SSH session and make a zenity window popup.
zenity --info --text="hello" --title="hithere" --display=:0
Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.
As you can see below I've chosen the "info" dialog type and the text inside it will be "hello" and the title of the window is "hithere" and it is going to show on X Window Display ":0" (the default). The --display portion is only necessary if you have multiple displays or if you are running from a remote SSH session.
Debian/Ubuntu/Mint Linux How To Set VLAN in /etc/network/interfaces
You can find many ways to specify the VLAN in your network configuration but I find this is the simplest and quickest.
In this case we are talking about a bridged adapter "vmbr0" but it works even if you just had a normal non-bridged interface.
The key here is that in vmbr0 you'll notice there is no IP address. We just specify "manual".
Below it is a similar stanza for "vmbr0.58" in this case 58 represents the VLAN (change the 58 to the number of your desired VLAN). Then below it we set the IP address or we could have used DHCP as well.
auto lo
iface lo inet loopback
iface enp2s0 inet manual
auto vmbr0
iface vmbr0 inet manual
bridge_ports enp2s0
bridge_stp off
bridge_fd 0
auto vmbr0.58
iface vmbr0.58 inet static

moodle install error Error reading from database
Error reading from database
More information about this error
It is usually not possible to recover from errors triggered during installation, you may need to create a new database or use a different database prefix if you want to retry the installation.
Solution:
This happened when I was running MySQL 5.1. Assuming your database details are right and the DB is up then make sure you are using the correct and required MySQL 5.5
After upgrading to MySQL 5.5 things were good.
PHP Displaying Blank Page on Apache
Almost always the reason will be that the php.so file is missing but also that php.conf is misconfigured.
In the problem machine it is actually PHP 7 installed so if you reference PHP 5 of course things wil be broken!
Take for example here:
cat /etc/httpd/conf.d/php.conf
#
# PHP is an HTML-embedded scripting language which attempts to make it
# easy for developers to write dynamically generated webpages.
#
LoadModule php7_module modules/libphp7.so
#
# Cause the PHP interpreter to handle files with a .php extension.
#
AddHandler php7-script .php
AddType text/html .php
#
# Add index.php to the list of files that will be served as directory
# indexes.
#
DirectoryIndex index.php
#
# Uncomment the following line to allow PHP to pretty-print .phps
# files as PHP source code:
#
#AddType application/x-httpd-php-source .phps
moodle displays code instead of outputting HTML
cat /etc/httpd/conf.d/php.conf|grep -i addhandler
AddHandler php5-script .php
Fix it and then restart Apache
sed -i s/"php5-script"/"php7-script"/g /etc/httpd/conf.d/php.conf
service httpd restart
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/geoip.so' - /usr/lib64/php/modules/geoip.so: undefined symbol: GeoIP_country_code_by_name_v6 in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/geoip.so' - /usr/lib64/php/modules/geoip.so: undefined symbol: GeoIP_country_code_by_name_v6 in Unknown on line 0
Solution:
Edit geoip.ini
vi /etc/php.d/geoip.ini
Comment out the .so like so:
;extension=geoip.so
service httpd restart
Starting httpd: httpd: Syntax error on line 221 of /etc/httpd/conf/httpd.conf: Syntax error on line 6 of /etc/httpd/conf.d/php.conf: Cannot load /etc/httpd/modules/libphp5.so into server: /etc/httpd/modules/libphp5.so: cannot open shared object file:

This is basically caused by the PHP module specified in php.conf being non existent. The error tells us it couldn't fnd /etc/httpd/modules/libphp5.so
OK let's see what PHP module we do have:
ls /etc/httpd/modules/libphp*
/etc/httpd/modules/libphp7-zts.so /etc/httpd/modules/libphp7.so
If you have one there that works for you then just update php.conf to match.
sed -i s/"libphp5.so"/"libphp7.so"/g /etc/httpd/conf.d/php.conf
sed -i s/"php5_module"/"php7_module"/g /etc/httpd/conf.d/php.conf
prosody xmpp server "Failed in all attempts to connect to proxy.eu.jabber.org"

No clue why it tries to use a proxy not explicitly specified. This could be because the proxy specified for the domain fails when someone is trying to send a file. I wish this could be disabled for security reasons in prosody.

qemu-img resize howto
The Correct Way To Resize In Place
qemu-img resize kvmuserwindows2008dcetest.img +1G
Image resized.
Below is a common mistake that some users make they are trying to specify a new image name but it can be resized in place (just make sure the VM is NOT running and you've backed up the data in case something goes wrong).
qemu-img resize kvmuser453111.img kvmuser453111-larger.img +5G

A user complained that their e-mails weren't being delivered but they actually made a small typo and used gmail.con so it wasn't working as expected of course!
VMWare Hardware virtualization is selected and cannot be deselected due to selection of VBS Insufficient resources to satisfy configured failover level for vSphere HA.
There is no such option as "VBS" that I can see in vSphere 6.7 I believe this is actually an issue because of using old hardware in this case L5420 doesn't support Nested Virtualization I believe.

migration/4 migration 4 is using too much CPU but not sure why. I think it was due to heavy IO or swapping at the time possibly.

I've been getting this error in ImageMagick on some .tif files even though it seems to actually convert properly.

Linux How To Rename Files
To remove all spaces from all files in the current directory
linux rename remove spaces
rename "s/ //g" *
The above won't work in Centos but in Debian based distros as rename in Centos doesn't work that way.
See this more comprehensive article.

=======
The Solution
Edit the vhosts that are having the trouble they probably have a hardcoded IP.
Change it like so:
<VirtualHost some-ip.here:443>
To
<VirtualHost *:443>
================
[root@thetor2017 conf]# grep 10.2.5.101 *
hostdomain.com.conf:
hostdomain.com.conf-orig:
========
apache shared ssl returns wrong certificate vhost
I believe it has to do with the IP they are hitting:
[root@thetor2017 conf]# host seconddomain.com
seconddomain.com has address 10.2.5.55
seconddomain.com mail is handled by 10 mail.seconddomain.com.
[root@thetor2017 conf]# host realtechtalk.com
realtechtalk.com has address 10.2.5.55
realtechtalk.com mail is handled by 10 mail.realtechtalk.com.
[root@thetor2017 conf]# host thirddomain.com.com
thirddomain.com.com has address 10.2.5.102
thirddomain.com.com mail is handled by 10 mail.thirddomain.com.com.
[root@thetor2017 conf]# host onedomain.com
onedomain.com has address 10.2.5.102
the IPs with .55 work fine with SSL
The IPs with .102 serve domain.cn because I believe it is the first vhost and cert by alphabet on that IP
the problem is in this vhost# domain.cn.conf:
it applies to onedomain.com and thirddomain.com.com because they use the same IP as domain.cn 10.2.5.102
Normally when using .55 the first domain it would find and search is the default 00-defaultsite.conf which points to the generic cert
On top of that domain.cn.conf has the IP as the vhost "
So it defaults to the first IP and cert it finds which is domain.cn rather than sending the default 10.2.5.55 generic cert

The solution is to update to the latest Ethereum client and wipeout your "chaindata" if that doesn't work. Ethereum is a work in progress and unlike stable currencies like Bitcoin and Litecoin it must be updated to the latest version or things won't work (which means almost weekly updates!).
PayPal IPN Failed "result: IPN Handshake Invalid"
This is often the result of PayPal's "item name" or another name having invalid characters or not supporting Unicode.
173.0.81.1 - - [17/Jul/2018:13:39:45 -0400] "POST //modules/gateways/callback/paypal.php HTTP/1.1" 406 - "-" "PayPal IPN ( https://www.paypal.com/ipn )"
A good clue is if you check the debug output of the IPN and find a mandatory column empty.
item_name =>
Obviously item_name has to be populated or things will usually break. Login to your PayPal settings and update your character encoding settings:
See how to do this in PayPal below:

ImageMagick How To Convert Specific PDF Pages or a Range
A very handy feature of ImageMagick's convert command is that it can convert PDF's to other image formats like jpg but did you know you can even manually select a range or specific pages from the PDF?
Here is an example of converting a range of pages from a PDF in this case pages 25 to 36:
convert -density 300 "vSphere 6.5-1.pdf[25-36]" vsphere.jpg
Here is an example of converting a list of specific pages from a PDF in this case pages 45,54,69:
convert -density 300 "vSphere 6.5-1.pdf[45,54,69]" vsphere.jpg
Linux How To Free Wasted Memory RAM in Buffers
We all know Linux is known for good memory management but is it really? It seems all on its own with hardly anything running that you can come back in days or weeks and find that almost all of your RAM is used!
And many will say "no don't worry it's buffers for optimization" but it doesn't seem to help because what is in buffers is not available to use for new programs running or ones that allocate more RAM as far as I can tell.
The reason I know this is because you can see that SWAP will get used so if there was enough RAM not eaten by buffers it should be freed for new or growing memory allocations but it is not.
So how do we fix this or clear out Linux's memory buffers to free RAM?
[root@realtechtalk.com ~]# free -m
total used free shared buffers cached
Mem: 3851 3738 113 0 3269 222
-/+ buffers/cache: 246 3605
Swap: 2999 0 2999
[root@realtechtalk.com ~]# echo 3 > /proc/sys/vm/drop_caches
[root@realtechtalk.com ~]#
[root@realtechtalk.com ~]#
[root@realtechtalk.com ~]# free -m
total used free shared buffers cached
Mem: 3851 146 3705 0 0 9
-/+ buffers/cache: 137 3714
Swap: 2999 0 2999
Now we can see that we have our RAM back!
Linux How To Eject and Insert a CD-R/DVD-R/BD-R Disc
Many people are aware of the "eject command" which works as you would expect.
To eject the disc:
sudo eject /dev/sr0
To insert the disc again you still use the same command but with the "-t" close try toggle:
sudo eject -t /dev/sr0
Linux Mint 18 Screen Goes Dark or Black After Screensaver or even when using the Desktop Solution
You can search for this bug and it seems like it may be related to ecryptfs and is many years old.
The symptoms are that you return to the computer and the screensaver was active or the screen was asleep/black and it doesn't seem to come back. But you check by SSH the computer is running fine and are frustrated you'll lose your running programs and have to reboot.
There is a simple solution:
Ctrl + Alt + F1
Ctrl + Alt + F8
Basically you are switching to another virtual console/screen and then back to screen 8 which is your Desktop. This removes the black screen and presents the login prompt and doesn't cause any loss of data or interruption to your session.
This also works if you are using your computer normally and the screen becomes partially dark or very dark. It seems related to the above bug.
It may also be related to a bug in the Intel i915 driver but this issue seems to plague Nvidia and AMD users too.
Some related syslog or dmesg errors you may see:

Of course change --dport and -s to suit your needs
#allow certain IP to access port 22

Postfix How To Change Sending IP Address To Specific IP Binding or Interface
I thought I'd post this becuase there is some bad information out there. Some guides tell you to edit /etc/postfix/master.cf (-o smtp_bind_address=) but this doesn't work. The same guide also says if you don't change it there you end up changing the listening IP/bind interface which is also not true.
Here is a simple and effective way to change Postfix's sending/binding/outgoing IP address (very important for reverse DNS and so mail servers don't block you):
vi /etc/postfix/main.cf
#add this option
smtp_bind_address=192.168.5.80
*Obviously change the 192.168.5.80 to the outgoing address you want to use for Postfix
How to qemu-kvm enable bridged networking in Debian Ubuntu Linux Mint on KVM containers
I've read a few guides about this but they didn't work for me.
sudo apt-get install bridge-utils
#don't think the above is enough it won't work still even though you have by default an /etc/qemu-ifup that handles it if you have the right tools and setup
sudo qemu-system-x86_64 -net tap -net nic -enable-kvm -cpu host,vmx=on ~/VirtualBox VMs/vsphere-vcenter/vsphere-vcenter.vdi
W: /etc/qemu-ifup: no bridge for guest interface found
vi /etc/networking/interfaces
Add the following br0 adapter and make sure you replace eth0 with your network adapter name such as "enp3s0"
auto br0
iface br0 inet dhcp
bridge_ports eth0
bridge_stp off
bridge_maxwait 0
bridge_fd 0
#restart your network/networking
sudo service networking restart
sudo qemu-system-x86_64 -m 11G -net tap -net nic -enable-kvm -cpu host,vmx=on ~/VirtualBox VMs/vsphere-vcenter/vsphere-vcenter.vdi
There is no more error or complaint about no bridge interface being found not that we've installed bridge utils and created a br0 bridge.
VirtualBox Nested Virtual Machine Containers with KVM Not Working no SVM or VMX module in the guest
I can't get vmx cpu extensions to show up in Virtualbox guests despite enabling nested paging and
enable vmx in virtualbox guest but this doesn't help that you check VT-X or the AMD Virtualization SVM it enables it for the guest to use BUT does not pass it through. This means if you check cat /proc/cpuinfo in the guest you will see the CPU doesn't support virtualization. It looks like VirtualBox still hasn't implemented this!
But there is good news I was able to install qemu-kvm and run straight from the VirtualBox .vdi directly and also enable the nested virtualization no problem.
#it looks like it is just not supported it's just easier to use KVM directly on the .vdi file!
qemu-system-x86_64 -enable-kvm -cpu host,vmx=on ~/VirtualBox VMs/test/test.vdi
Virtualbox is a great project and way for virtualizing but it is disappointing that they don't just pass through the virtualization CPU flags for nesting.
VSphere InternalServerError - Error When Adding Permissions
InternalServerError (com.vmware.vapi.std.errors.internal_server_error) => {

I was getting the error but it almost seemed delayed as if it were from the previous operation a minute before and not the current. You can just refresh and try again but it seems like a bug. The permissions show they have applied but hopefully they really have and nothing is broken!
NFS Share Won't Mount Solution - mount: wrong fs type, bad option, bad superblock on 10.10.2.20:/tmp/nfsmount
nfs mount failed:
mount 10.10.2.20:/tmp/nfsmount /mnt/nfs/
mount: wrong fs type, bad option, bad superblock on 10.10.2.20:/tmp/nfsmount,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so
In this case the client machine didn't have nfs-utils installed! You would think that when trying to mount that the error would indicate this!
yum -y install nfs-utils
So make sure you have nfs client utilities installed on the machine you are trying to mount the nfs share from!

Install NFS (Network File System) On Debian Linux Ubuntu Mint Howto
sudo apt-get install nfs-kernel-server #oops there are no exports so it won't startsudo /etc/init.d/nfs-kernel-server start
* Not starting NFS kernel daemon: no exports.
#we will use the /tmp/nfstestshare directory for our NFS share
mkdir /tmp/nfstestshare
#add it to /etc/exports (basically what NFS checks to determine what to make an NFS share)
/tmp/nfstestshare 192.168.1.5(rw,sync,no_root_squash)
As you can see the brackets take 3 variables as follows:
- ro (readonly) or rw (readwrite)
- sync means no changes to the directory until changes are committed
- no_root_squash allows root to access the directory

I had this error in an unsupported CPU on VMWare 6.7 and apparently this sometimes works especially on older VMWare versions like 6.5 5.5 etc (but in my case it did not).
- To make sure it proceed when you see "Loading VMWare"
- Hit "Shift+O"
- Then add "ignoreHeadless=TRUE"
See an example below:
Usually it will get you past the mentioned screen but may fail with other errors such as an Unsupported CPU.
In the case your computer/server/CPU is supported and this is just a bug you will be able to complete the install. But you'll want to make the boot option above permanent as each time you'll need to manually specify ignoreHeadless=TRUE or you won't be able to boot.
Enable SSH on the ESXi host, login and type the following command to make it permanent:
[root@localhost:~] esxcfg-advcfg -k TRUE ignoreHeadless

For most people they will probably choose the smartly placed #1 .json option on VMWare's list as it applies to the most use cases I would think:
embedded_vCSA_on_ESXi.json
Contains the minimum configuration parameters that are required for deployment of a vCenter Server Appliance with an embedded Platform Services Controller on an ESXi host.
In plain English you have an ESXi host and want to setup the vSphere/vCenter management off the same server.
OK think you're ready now?

Hard Drive Serial Number Examples
The reason for this article is because a lot of us don't physically see our hard drives they are often remote in a datacenter etc and the actual serial number we see in SMART is not enough to check for some manufacturers.
A good example is our first one the Toshiba
=== START OF INFORMATION SECTION ===
Device Model: TOSHIBA DT01ACA200
Serial Number: 33FMDW4AS
If you enter the serial in Toshiba's site above: https://myapps.taec.toshiba.com/myapps/admin/jsp/webrma/addRequest1NoLogin.jsp
You will get the following result:
| 33FMDW4AS | Warranty could not be determined for this Non-HDD serial number. If you have any questions you may contact Toshiba at 1-855-898-1905. |
That is because you are missing the "TZ5" at the end. See when you add the TZ5.
| 33FMDW4ASTZ5 | HDKPC09A0A01S | Out Of Warranty | Out of warranty. Exp Date: 2015/03/26 |
Hard Drive Full Serial List Examples
The format will be that the extra characters before or after the serial number are what you have to add on your own.

OpenVPN auth-user-pass-verify ENV script error
Starting with newer versions of OpenVPN I believe 2.2+ you need to have "script-security 3" set or you can't execute a third party script.
Prior to that you could also use the auth-user-pass-verify like this:
auth-user-pass-verify ./validate.pl "$username $password $ip" via-env
Options error: the --auth-user-pass-verify directive should have at most 2 parameters. To pass a list of arguments as one of the parameters, try enclosing them in double quotes ("").
However this no longer works. The way env works no longer gives you the variables as variables that you can pass as arguments.
It now works as normal so for example in a shell script you call from OpenVPN.
Just referencing $username and $password gives you the login information the user sent. This seems to have taken effect in version 2.3 or 2.4 or possibly even 2.2
OpenVPN error ERROR: Cannot ioctl TUNSETIFF tun: Operation not permitted (errno=1)
This basically means that you are running as non-root and you need to be root to create the tun0 or tap0 device on OpenVPN. You could try sudo or adding the openvpn binary to the list of sudoers.
Howto install ioncube loader to PHP by Zend
First of all download the raw .so file from zend:
Copy the one relevant to your PHP version to /usr/lib64/php/modules/
eg.: cp ioncube_loader_lin_5.3.so /usr/lib64/php/modules/
Then in your /etc/php.d/ directory create the file:
vi /etc/php.d/zend.ini
zend_extension = /usr/lib64/php/modules/ioncube_loader_lin_5.3.so
After that restart apache/httpd and you'll be good to go!

not allowed to execute '/usr/bin/apt-get install eclipse' as root linux sudo user permisson issue and solution
This is most likely to happen on a normal GUI system like Ubuntu or Linux Mint. If you or the user is meant to have sudo / root privileges it is as simple as editing the following files:
Now assume your username is "iamtheuser"
vi /etc/group
adm:x:4:syslog,iamtheuser
sudo:x:27:anotheruser,iamtheuser
Find the above lines and add a comma and "iamtheuser" right after as shown in the example above. You'll have to log out and login and things will be fine after that. If you want to stay logged into the GUI you could always just ssh in to localhost and that ssh connection would give you the new privileges.
Database Error One or more of the WHMCS database tables appear to be either missing or corrupted. Please check and repair. - WHMCS Solution
Database Error
One or more of the WHMCS database tables appear to be either missing or corrupted. Please check and repair.
This error can be misleading especially if you know you are using a known good backup or restoration of the WHMCS database. The error can also be that the user lacks permissions to read and write to the database.
To check to this in MySQL shell:
GRANT read,write to dbusername@localhost on dbname;
After that things should work again.
postfix errors fatal: no SASL authentication mechanisms /usr/libexec/postfix/smtpd: bad command startup -- throttling solution
Jul 3 22:12:17mailserver postfix/smtpd[6195]: fatal: no SASL authentication mechanisms
Jul 3 22:12:18mailserver postfix/master[4881]: warning: process /usr/libexec/postfix/smtpd pid 6195 exit status 1
Jul 3 22:12:18mailserver postfix/master[4881]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling
This only ever happens in my experience when the authentication method is actually Dovecot. Usually the problem will be that Dovecot cannot start due to a misconfiguration and or permissions issue.
The solution is to try to trace through /var/log/maillog and find out what is wrong with Dovecot (assuming it cannot start).
After this postfix should work fine.
You should also enable debug info in dovecot.conf like this:
auth_debug = yes
auth_debug_passwords = yes
auth_verbose = yes
To give you an idea of what commonly goes wrong after a new Dovecot migration or install:
dovecot: auth: Error: passwd-file /etc/dovecot.passwd: open(/etc/dovecot.passwd) failed: Permission denied (euid=97(dovecot) egid=97(dovecot) missing +r perm: /etc/dovecot.passwd, euid is not dir owner)
Solution:
chmod +x /etc/dovecot.passwd
Another error:
dovecot: lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Connection refused
In this case you need to make sure /var/run/dovecot/auth-userdb and also /var/mail is set to the correct user id and group id or username/groupname as in your /etc/dovecot/dovecot.conf
first_valid_gid = 502
first_valid_uid = 501
last_valid_gid = 502
last_valid_uid = 501
mail command line examples of how to send an email using Linux / Unix and the Bash Shell or Scripting
A simple way that may work for a lot of people who just need basic output for their scripts or daemons to announce an action is this:
echo "body or message" | mail -s "realtechtalk.com" user@domain.com
If you want to send a text file as the body just do this instead:
mail -s "realtechtalk.com" user@domain.com < /tmp/sometxtfile.txt
These are some very basic but simple and powerful examples that could assist in basic shell scripting such as taking the output of a command and e-mailing it based on a cronjob etc..
An excellent resource on this is also here.
named [FAILED] - zone 1.168.192.in-addr.arpa/IN: not loaded due to errors. - bind error solution
Centos when copying old files and restarting it seems load everything fine and then says [FAILED] with no log or other message.
service restart named
named [FAILED]
Check more thoroughly you may have missed the error if you have lots of zones!
service named restart|grep error
zone 1.168.192.in-addr.arpa/IN: not loaded due to errors.
zone 2.168.192.in-addr.arpa/IN: not loaded due to errors.
zone 3.168.192.in-addr.arpa/IN: not loaded due to errors.
Check the zone file you probably made a mistake that was accepted in an older version of bind/named:
$TTL 60 ; 172800 seconds
$ORIGIN 3.168.192.IN-ADDR.ARPA.
@ IN SOA ns1.rtt.com. ns2.rtt.com. (

)

3 IN PTR dubmail-smart-www.testdns.com.
4 IN PTR path-mail-vlan20.testdns.com.
17 IN PTR testdns.com.
18 IN PTR tehka.testdns.com.
19 IN PTR khyra.testdns.com.
20 IN PTR skulda.testdns.com.
21 IN PTR thehip.testdns.com.
22 IN PTR ccipe.testdns.com.
Notice above how the IN NS does NOT have a period at the end of the TLD or .com
This is a mistake and not allowed and not tolerated in modern versions of bind but clearly in previous ones it was fine and working!
So just add the dots at the end like below and it will be good.
IN NS ns1.rtt.com.
IN NS ns2.rtt.com.
The above is just a real life example and there was no mention specifically of this being the issue in the output or logs on the server.
OpenVPN cannot ping remote IP routing loop issue after connecting
Sometimes if you have a very basic configuration OpenVPN on the client side for some reason sends all traffic to the OpenVPN server IP through the tun0 which is of course impossible and creates a block or routing loop.
This is because you need to use your normal ISP/LAN gateway to hit the OpenVPN server if it is remote/offsite as is usually the case. So if you are connected to the OpenVPN through say a tun0 device and your routing is set to connect to the OpenVPN server via the tun0 device this breaks everything!
Example below:
I am very familiar with OpenVPN servers but I can't seem to ping the gateway or the DNS server for some reason.
Mon Jul 9 21:46:56 2018 [access] Peer Connection Initiated with [AF_INET]92.85.42.11:1194

Notice how the route for the VPN server 92.85.42.11 above is going through tun0. Of course this breaks everything. How can you connect to the remote IP server when it is going through a tunnel already running to it. It is basically like a routing loop. You connect to the Public IP of the OpenVPN server and then you are telling all traffic to that VPN network must first go over the tunnel but really all you've done here is broken the connection to the VPN server!
tun0 IP: 10.45.58.249
fix routing loop:
ip route del 92.85.42.11
Simply just delete the erroneous route to the VPN server IP and this will force traffic to pass properly through the tunnel and allow you to stay connected to the VPN tunnel this way and actually use it. Alternatively you also could have manually specified that the VPN IP of 92.85.42.11 be specifically routed over a particular interface such as 192.168.1.1 or interface such as eth0 or enp3s0 etc..
Maximum number of connections from user+IP exceeded (mail_max_userip_connections=10) Dovecot Solution
This happens because Dovecot limits the maximum IMAP connections per IP to just 10. This may be fine for a single client side IP but if an entire office or multiple users are behind one IP or a single heavy user is active then you will get bizarre errors in your e-mail clients such as "Password Incorrect" or similar in Thunderbird. It won't be obvious on the client side as to what the problem is and they will probably just think the server is misconfigured.
dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=10): user=<user@domain.com>, method=PLAIN, rip=10.15.12.5, lip=10.15.12.59, TLS
Jul 10 14:16:21 mailserverdovecot: imap-login: Warning: SSL alert: where=0x4008, ret=256: warning close notify [10.15.12.5]
add this to dovecot.conf:
mail_max_userip_connections = 50
Restart dovecot and after that you should be good to go.
Note that some users say you have to put the above in an imap stanza like this (but it was not necessary for me):
protocol imap {
mail_max_userip_connections = 50
}

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Apache/2.2.15 (CentOS) Server at testdomain.com Port 80
Check your apache log and find something like this:
.htaccess: No comments are allowed here
the issue was .htaccess literally not allowing comments after a rule:
deny from 207.114.253.34 #blocked user
Look at the line above. Apache certainly didn't help with its cryptic "no comment allowed here". I wish it would mention what line but it literally meant "no comments allowed at the end of a rule". This is crazy because it worked fine in a previous version of Apache. Another caveat and gotcha of upgrading from an older Apache server that what worked before no longer does.
Linux Mint Black Screen after boot no graphics solution
This is not the normal "black screen" issue and I was shocked to eventually find out why. The normal advice of reconfiguring Xorg didn't work. Even booting into "Recovery Mode" did not help.
Here is the short end of the stick that fixed it:
sudo apt-get install mdm mate-desktop-environment
Yes you got it right, mdm and the mate-desktop-environment / gnome were somehow uninstalled. This must be when removing a related package sometimes you just say Y and it uninstalls other important and necessary things! This is just a guess.
I also couldn't login after that it would kick me right out. This has something to do with Virtualbox (I wasn't using it) so I just uninstalled it.
Linux Mint 18 has so far been a very finicky environment compared to the previous 17.
Here is my saga:
sudo service mdm restart

Duplicate entry '2147483647' for key 'PRIMARY' MySQL Error Solution
This usually happens when you are using something like an INT and try to insert a larger value than the maximum which is larger than "2147483647"
On a practical term I have seen this and been guilty of this error when using scripts like PHP and generating large random numbers:
$hash = mt_rand(5,9999999999999);
Obviously that many 9's are more digits than the maximum of an INT resulting in that error. Change your code accordingly to avoid the problem:
$hash = mt_rand(5,2147483647);

Now restore the "places.sqlite-fixed" to places.sqlite and reopen Firefox
After doing this my address bar history worked fine and perfectly! No need to start with a fresh database and lose valuable history and shortcuts to key sites you visit!
sign_and_send_pubkey: signing failed: agent refused operation - SSH Solution
sign_and_send_pubkey: signing failed: agent refused operation
This happens when you don't manually add your ssh key with ssh-add it is some weird new feature in SSH or Ubuntu/Debian that causes this weird problem.
Solution:
ssh-add
Identity added: /home/user/.ssh/id_rsa (/home/user/.ssh/id_rsa)
Centos PXEBoot NetInstall Failure - Pane is dead
ValueError: new value non-existent xfs filesystem is not valid as a default fs type
Pane is dead
From what I read this is misleading and has to do with the fact that the initrd and kernel are mismatched.
This is a hard situation because for some older hardware I am using the Centos Plus kernel which has modules that I require for an older server/NIC. This seems to have cropped up in the past few months and there is no simple fix which is quite frustrating.
I wish RHEL/Centos would provide a CentosPlus kernel for their PXE boot image as this essentially stops things from working and creates a PXEBoot/NetInstall scenario that cannot be relied on because it seems to pull other image data from the Centos repo which ends up breaking in the event that the repo has been updated and your kernel/initrd are mismatched.
But it worked before the whole time so something unexpected or undesirable has changed upstream unfortunately. For now I am not sure of the solution short of creating my own PXEBoot initrd image and kernel.
Intel NUC J3455 Linux Kernel freeze slowness 4.4.98 errors
It looks like this has something to do with APIC but I am not sure. I have similar CPUs with a different MB and BIOS that work fine on the same type of kernel. A lot of time the issue is because of the C-step setting in the BIOS.
The same thing happened on the 2.6 kernel with Centos 6 but this is a homebrew 4.4 kernel so I am not sure why it is happening when even Centos 7 (3.2) kernel works OK.
Solution - It comes down to the BIOS settings:
*The most critical part is this:
Boot:
OS Selection "Linux" (now note this is weird but even if you are booting without UEFI this setting applies still).
If you don't choose Linux as your OS everything runs snail slow.
Security:
Disable "Execute Disable Bit"
Disable "Intel Platform Trust"
Power:
Disable "Enhanced Intel Speedstep Technology"
Disable "OS ACPI C2 Report"

Other symptoms are that everything seems to run very slow such as basic keyboard input there is a lot of lag even when opening top or waiting for the output of dmesg etc..When typing it basically feels like you are on a dialup modem connecting to a server on the other side of the world with packet loss or that is saturated.
named[1525]: error (broken trust chain) resolving 'min-api.cryptocompare.com/A/IN': 173.245.58.78#53 solution
So you restarted your router/dhcpd server or for some other reason you wonder why DHCP is not working on any of your clients? You go and check that named is in fact running fine.
But then you check /var/log/messages and see this error for everything hostname:
named[1525]: error (broken trust chain) resolving 'min-api.cryptocompare.com/A/IN': 173.245.58.78#53
I've only ever seen this when the time on the server was off. It is important to make sure you are running ntpd or ntpdate on boot and at all times. Once you change your time to the correct time things will work again.
Linux Ubuntu Mint Debian cannot play xvid,x264,mp4 or any videos codec issue - xplayer Could not initialize supporting library.
In xplayer I get the following error "Could not initialize supporting library.". It actually looks more like a gstreamer issue.
For those wondering what the default video player is called it is "xvid" and not "totem" anymore like previous versions.
Basically it looks like some codecs are missing when I uninstalled another program it uninstalled other programs and codecs that it shouldn't have.
I've tried installing all the gstream packages and other codecs but nothing has helped so far.
There is also this console output:
libva info: VA-API version 0.39.0
libva info: va_getDriverName() returns -1
libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)
Solution:
sudo apt-get remove gstreamer1.0-vaapi
wget howto output to terminal or script instead of file
wget -qO
You just need the -qO switch and you'll be good to go, the output then goes to your console/screen/script rather than a file.
imagemagick convert to chop off top of image
convert -crop -0-400 image.jpg image.pdf
The -crop -0-400 is what does it. The 0 says not to chop anything from the left. If you want to chop the left of course change 0 to whatever pixels you want chopped from the left. The 400 says to chop 400 pixels off the top.
This is useful if you have a bunch of images/scans where the same area at the top needs to be chopped.
Sometimes the -trim option (such as the case of white space on top) is wrong and ends up cropping the image and losing some text.
ImageMagick's convert is very useful but tricky to find some things out as I find it to be less than intuitive sometimes.
How To Set or Change Useragent in Firefox and Seamonkey
In your browser go to "about:config"
Right click and choose "New" -> "String"
The name should be:
general.useragent.override
String Value:
Mozilla/5.0 (Linux; U; Android 2.2.1; en-ca; LG-P505R Build/FRG83) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
You don't even have to restart to make this work.
How To Turn Any .iso file into a bootable USB drive
This works for almost all ISO's I find (at least Linux based):
sudo dd if=CentOS-6.9-x86_64-minimal.iso of=/dev/sdg bs=20M
20+1 records in
20+1 records out
427819008 bytes (428 MB) copied, 118.233 s, 3.6 MB/s
Of course change the .iso filename above and the /dev/sdg to your desired USB drive!
Linux Mint Ubuntu Debian How To Disable Webcam Automatically Onboot To Prevent Spying and Privacy Violations
It is well known hackers, the NSA, CIA and other groups have created malware to secretly turn on your webcam and microphone on your phone, tv etc.. But fortunately on our computers and laptops we have some options.
Most webcams use the "uvcvideo" kernel module / driver. You can disable this in two ways on boot. I recommend both just as a failsafe.
Disable it on rc.local once your system boots automatically
Add the following to /etc/rc.local:
/sbin/rmmod uvcvideo
Even if the kernel module was loaded during boot this will unload it.
Disable it from loading at all in blacklist.conf
Edit /etc/modprobe.d/blacklist.conf
blacklist uvcvideo
Now of course note a hacker who gains access as root/admin could still load this driver and spy on you but it is a reasonable amount of privacy. To increase security you should use electrical or duct tape over your microphone and webcam itself.
As a more invasive mode you could also edit your initramfs and kernel not to even contain the driver (but the issue is that on kernel upgrade the uvcvideo driver will be back).
You could also use a cronjob like this every minute:
sudo crontab -e
*/1 * * * * /sbin/rmmod uvcvideo
This would try to unload the driver every minute just in case something malicious did activate it again.
IcedTea Java Web Viewer Config Utility How To Enter
In at least Ubuntu and Mint there is nothing intuitive about configuring Java.
Execute it to get to it:
itweb-settings
You'll be able to configure different options and variables.
You can also check under Security as some of those settings could prevent applets from starting or prompting to be accepted (because they are insecure-like most things Java :))
Debian Linux Mint Ubuntu Disable Automatic apt-get update
sudo chmod 000 /etc/cron.daily/apt-compat
This is the easiest way to disable the cron without anything more invasive like deleting the file.
After that you won't have anymore apt-get's starting.
This can be critical for systems without much extra RAM that is not in use. I've seen systems that have swapped and crashed over apt-get.
How To Install Seamonkey Web Browser on Debian Ubuntu Linux Mint
It's a little tricky if you are running a 64-bit OS which most people will be.
The weird thing is that the Seamonkey website for Linux seems to only provide a 32-bit download.
seamonkey-2.49.2.tar.bz2
First unpack it
tar -jxvf seamonkey-2.49.2.tar.bz2
Try to run it
./seamonkey
XPCOMGlueLoad error for file /home/queenlazina/Downloads/seamonkey/libmozgtk.so:
libgtk-3.so.0: cannot open shared object file: No such file or directory
Couldn't load XPCOM.
Seems that libgtk is installed:
ls /usr/lib/x86_64-linux-gnu/libgtk-3.so.0
/usr/lib/x86_64-linux-gnu/libgtk-3.so.0
But note it is 64-bit and you need the 32-bit library since Seamonkey is 32-bit.
We need to enable i386/32-bit architecture and add the libgtk for 32 bit
sudo dpkg --add-architecture i386
sudo apt-get install libgtk-3-0:i386
After that you can run Seamonkey finally!
Prevent SSH Bruteforce and Hacks By Disabling Password Authentication
One simple way to keep your server public but almost impossible to hack via SSH is to disable password authentication over SSH. This means the only way in is via your own private key that only you should have.
Edit your /etc/ssh/sshd.conf file
Set this option
PasswordAuthentication no
Restart your SSH server.
service sshd restart
Now your server will be much more secure, even if someone has the password they cannot login remotely no matter what (so long as no one has stolen your private key). This makes bruteforcing absolutely impossible, so long as they don't enter another way, get root access and enable password login again.
SMF Forums / Simple Machines Forums Not Displaying Images Theme or Styles Properly using 127.0.0.1
This is one thing that has me wondering about SMF. It is apparently a known issue but in the latest version and new install nothing looked right because it was using http://127.0.0.1 to find everything! How on earth would it ever do this or think it is normal?
Excerpt of crazy html code it produces that causes the issue:
<link rel="stylesheet" type="text/css" href="http://127.0.0.1/smf/Themes/default/css/index.css?fin20" />
<script type="text/javascript" src="http://127.0.0.1/smf/Themes/default/scripts/script.js?fin20"></script>
<script type="text/javascript" src="http://127.0.0.1/smf/Themes/default/scripts/theme.js?fin20"></script>
<img id="upshrink" src="http://127.0.0.1/smf/Themes/default/images/upshrink.png" alt="*" title="Shrink or expand the header." style="display: none;" />
<img id="smflogo" src="http://127.0.0.1/smf/Themes/default/images/smflogo.png" alt="Simple Machines Forum" title="Simple Machines Forum" />
</div>
To repair it you need to get a tool from the SMF site: https://wiki.simplemachines.org/smf/Repair_settings.php#Download_the_Repair_Settings_Tool
Get the tool run it and you'll see some output like this:
Almost always aside from MySQL DB you should change 127.0.0.1 to the domain name of your server.

solution mysqldump: Got error: 1044: Access denied for user 'user'@'localhost' to database 'thedb' when using LOCK TABLES
It is simple the user just needs to be given the "LOCK TABLES" privilege.
As root run this command:
GRANT LOCK TABLES ON yourdatabase.* TO yourmysqluser@localhost;
MySQL How To Grant Access To ALL Databases For Export and Backup Purposes
GRANT SELECT, LOCK TABLES ON *.* TO yourmysqluser@localhost;
All you need to do a full MySQL dump on all databases is the SELECT and LOCK TABLES privileges. This way you don't have to use the mysql root user. Data could be compromised this way but at least no harm from manipulation, changes or deletion are possible by locking down the privileges to the minimum for a full MySQL dump and backup.
Here is a command you could use to dump all databases.
mdadm how to stop or start a check
It's fairly simple to start or stop a check but I do wish mdadm's command had this built in. Sometimes it will do a check at the worst time causing the server to crawl to a halt.
Stop check on md126:
echo idle > /sys/block/md126/md/sync_action
Start check on md126:
echo check > /sys/block/md126/md/sync_action
vzquota : (error) Quota on syscall for id 4532: No such file or directory vzquota on failed [3] OpenVZ Error and Solution
Starting container...
vzquota : (error) Quota on syscall for id 4532: No such file or directory
vzquota on failed [3]
Solution
vzquota drop 4532
Then start the container and it should work. It actually happened after migrating the VPS manually to another location (very common).
Another way of doing essentially the same is the following:
