OpenVZ has made vzctl version 4.7 default to using ploop which is a big annoyance.  No one wants it otherwise we'd use Xen or KVM.

Make sure to manually specify vzctl 4.6.1 or you will have issues with old scripts breaking since it defaults to using ploop (a single image like Xen/KVM).

Here's a list to old versions of vzctl.

It's always bothered me how Wordpress basically forces the user to provide their hosting credentials to install themes and plugins.  How do know for sure the data is not being saved, intercepted and being provided backdoor access to the NSA or other agencies or even just being misused by others with access?

Here's how to close the security hole above and if you're already given Wordpress your credentials make sure you change everything associated it with it.  Eg. change your ftp username and password, database password and if the same login gives you access to your hosting account/control panel you'll need to change all of your e-mail passwords too.

1. Search for themes from their website directly.
2. Download it to your computer, extract the zip file.
3. FTP/Upload the extracted directory to your hosting account to the "wp-content/themes" directory for your domain.
4. Activate it from your Wordpress

Yes the above takes a few extra steps but is well worth the peace of mind.

Error: database disk image is malformed

Solution:
yum clean all

On primary node

drbdadm connect all

On secondary node
drbdadm -- --discard-my-data connect all

 

fdisk unfortunately can't do this and I'm not sure if there's any updated version that handles it but parted can do it.

Here's an example of how to do it:

parted /dev/sda print

1      17.4kB  1024MB  1024MB  ntfs         primary
2      1024MB  16144MB  15120MB  ntfs          primary

/dev/sda1 would be the first partiton

/dev/sda2 would be the second partition

You can then just access them like any other normal partition.

Hit Alt + F10 before the system boots and you'll boot into the recovery drive and be able to restore your system, of course note that all of your data will be wiped out.

Start -> Administrative Tools -> Server Manager

Under "Computer Information" click "Configure Remote Desktop".

Under "System Properties" choose the type of "Allow connections" you want.

That's all there is to enabling RDP Access in 2008 server.

"Detecting hardware, please wait..."

Solution

This occurs if you are installing with low RAM such as 128MB
Bump it up at least to 512MB for the install

lvextend -L +10G /dev/kvmvm/w2k8r2evalstandard
  Extending logical volume w2k8r2evalstandard to 20.00 GiB
  Logical volume w2k8r2evalstandard successfully resized

The above adds 10GB to the logical volume.  Of course you must resize the filesystem using other tools to take advantage of the space.

This problem seemed to happen recently but was likely causing issues before.

Now there are a few reasons why this can happen especially if your adapter has DND mode enabled (disable it).

However that wasn't my issue and I only figured it out the other day  when  by fluke if you're on the phone (making a call) then  calls will come in.

That's when I figured out the solution:

This likely applies to other adapters but in a Sipura/Linksys you'll find this under "Advanced" settings for your line.

Enable both of those especialy the Keep Alive as otherwise the PBX/Asterisk/server won't realize your phone is alive and ready to receive calls.

The above seems to have solved it for me.

yum installed the wrong version, the devel does not match the actual running kernel!
 

This seems to mainly affect new installs of Windows and especially on XP randomly.

There are whole pages dedicated to the subject but none of them have a simple proper solution.

They and Microsoft say to use "Microsoft Fix It", the only problem is it requires .NET and many new installs of Windows don't have it by default.

The simple solution you asked for

Just reboot Windows and that is how I fixed it.

http://deepxw.blogspot.ca/search/label/Universal%20Termsrv.dll%20Patch

The above site has the patch that does this essentialy turning a Desktop Windows into a full fledged RDP server.

mencoder -fps 30 -ss 00:00:38 -oac lavc -ovc copy 152408.mp4 -o soundedit.mp4

The -ss flag means to start at 38 seconds (so the first 38 seconds of video will be removed).

 cat /etc/some.conf|grep -Ev '^#|^;|^$'

This assumes that comments start with # or ; (adjust as necessary).  Also note that the ^$ omits blank lines.

This can happen when you install RPMForge or other repos with the wrong architecture and here's how you fix it (simply uninstalling won't usually fix it):

The above in some cases I've seen is a sign of a DOS attack or can occur if users are using services like torrenting, proxy, VPN etc...  Do not take it lightly as the above can knock a server offline if the table becomes full and I've also seen full crashes and kernel panics shortly after.

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Edit all repos in /etc/yum/repos.d/* to exclude=php* (the problem is that repos like rpmforge elrepo, epel have PHP and it ends up conflicting and creating upgrade/install issues with the PHP that comes from the main Centos repo)

I'm not sure what is causing this and have never seen it on any server before.

One way with CPanel is just to use /scripts/easyapache and rebuild everything since who knows what else has gone wrong if the config file got messed up like that.

This is the entire contents of httpd.conf, it became corrupted somehow.

I never found a solution to do it live (nothing worked that I found) so it looks like a relogin is required.

Check your maximum file limit

 cat /proc/sys/fs/file-max
824460
 

This is different than your actual's user limit which you'll see below

ulimit -n
1024

Try and set it higher but it won't work

ulimit -n 65000
-bash: ulimit: open files: cannot modify limit: Operation not permitted

Set system wide defaults

sudo vi /etc/security/limits.conf
*             hard    nofiles           600000
*             soft    nofiles           500000

Making it live from a shell session (it won't work for your GNOME/XWindows session itself)
sudo su
root@homebox:/home/one# ulimit -n
1024
root@homebox:/home/one# ulimit -n 60000

ulimit -n
60000

root@homebox:/home/one# ulimit -n 60000
root@homebox:/home/one# ulimit -n
60000
root@homebox:/home/one# su - one
one@homebox:~$ ulimit -n
 

It's not as simple as "yum install" as you can see below and it doesn't stop there.

Run what is below to avoid dependency hell that I decided not to paste.

yum -y install package-cleanup
package-cleanup --problems
package-cleanup --dupes
package-cleanup --orphans
rpm -Va --nofiles --nodigest
#this fixed it
yum clean all


This will require downtime but I couldn't fiind another way that worked:

 echo y|yum remove php-*;echo y|yum install php53*

yum -x php53-odbc64 install php53*

Your php.ini will probably be wiped out and overwritten so make sure you enable short tags or PHP code with

/etc/php.ini
short_open_tag = On


Cannot find /usr/include/openssl/ssl.h.
Did you run the pre-install commands?

I was worried the server was hacked, I was logged in already as root but couldn't login to CPanel or a new SSH session.  I even reset the password from the shell and it did not work still.

The reason is CPanel Hulk, it detected a brute-force attack so it locked down the root account entirely even from the correct password.  According to cPanel the best way around this is to whitelist your IP.

http://forums.cpanel.net/f5/password-not-working-whm-cpanel-root-administrator-297262.html

I was aware of CPanel Hulk but didn't know it completely locks an account even if the password is correct from non-offending IPs so this is something to be aware of, someone could potentially create a denial of service against any of your services/accounts just be intentionally bruteforcing them.

There was an error creating the child process for this terminal

Failed to create pipe for communicating with child process (Too many open files)

I get this when trying to open a new tab or new window even.  I've had far more sessions open (literally dozens) before without getting this error.

Movie-Aspect is undefined - no prescaling applied.
videocodec: libavcodec (720x1280 fourcc=34504d46 [FMP4])
[mpeg4 @ 0x2c91c00] timebase not supported by mpeg 4 standard
Could not open codec.
FATAL: Cannot initialize video driver.

That is the error I would get, I thought it was a codec error something else.  By fluke I saw something about ffmpeg where someone recommended manually telling it to the "fps" and it worked.  My phone uses 30fps so I knew to do the following:

mencoder -fps 30  -vf rotate=1 -o output-copy.avi -nosound -ovc copy 25825.mp4
All I had to do was specify "-fps 30" and it worked whereas before the resulting video was just 1 frame with nothing basically.

This seems like it will be common with Samsung phones or maybe a lot of Androids.

ssh -L 5905:localhost:5900 root@yourserver.com

The "-L" means to create a port forward to a port on your server.

The 5905 means the port on your computer that will be used to access the port 5900 on the remote server.

localhost is the IP that you use to access the port forward (you can change it to 0.0.0.0 which will be all IPs on your system/computer but localhost is good for security and privacy unless a whole network of people need access).

On some CPanel installs we see complaints of "/usr/local/cpanel/bin/apache_conf_distiller" causing 100% cpu usage without any solution.

Killing the process causes it to spawn again, actually it seems it tends to spawn multiple processes itself.

Restarting CPanel itself is a temporary but not permanent solution.

[Wed Jan 08 18:50:07 2014] [emerg] (28)No space left on device: Couldn't create accept lock (/etc/httpd/logs/accept.lock.15449) (5)

This may happen when trying to restart Apache and you find it dies right after starting and check /var/log/httpd/error_logs.

What is the cause of this?

1. You could be out of disk space (if you're not then see #2 and below)
2. You're out of Semaphores, you need to kill all the old ones.

Check to see current Semaphores, if Apache has stopped it should have none.  If you run the command below and see them you need to manually kill them.

ipcs -s

0x00000000 13336595   apache    600        1        
 

The bash script below will kill all the old semaphores and you should be able to start Apache succesfully after that.

for ipcs in `ipcs -s|awk '{print $2}'`;
do
echo "ipcs=$ipcs"
ipcrm -s $ipcs
done

Just in case anyone is wondering that is the case, it can make troubleshooting impossible if you're making changes to php.ini but don't realize the webserver must be restarted for those changes to apply (contrary to running php-cgi which always looks up the current .ini settings).

I was having an issue with only certain random/jpeg files with the functions imagecreatefromjpeg imagecreatetruecolor and other related ones.

This issue was annoying basically it seems like a libgd issue/bug with newer versions of PHP and it was difficult to trace-out.  One very useful thing that helped me was using "php-cgi" and passing the query string as an argument eg:

php-cgi images.php source=IMG.jpg (that way you get all the error messages which lead me to below):

PHP Warning:  imagecreatefromjpeg(): gd-jpeg, libjpeg: recoverable error: Premature end of JPEG file

The solution is to tweak the PHP GD settings to ignore this warning

/etc/php.ini

[gd]
; Tell the jpeg decode to ignore warnings and try to create
; a gd image. The warning will then be displayed as notices
; disabled by default
; http://www.php.net/manual/en/image.configuration.php#ini.image.jpeg-ignore-warning
gd.jpeg_ignore_warning = 1

The above is how I did it, if you don't do it properly you'll find that you are still using the old version (so verify in About that it is the new version).  I've verified the above method works perfectly, it's great if you're using an older version of Linux and need to update the most commonly used programs like Thunderbird and Firefox.

"Static Leases"

Fill out an empty line:

Those first 3 fields are mandatory, if you miss it then the changes will be lost even if you try to save.

Make sure you've done it right but clicking "Save" and then "Apply Changes" at the bottom to make them active.

Then get a new DHCP lease and make sure the IP is correct.

This server has been running for weeks without issue, it's currently only using 1 of 2 CPUs as it is running in the office as a test bed (mainly due to the handle 12 bay storage/great for testing HDDs).  The errors below seem to mainly be from AMD CPUs, it's only happened a single time and in the days since I got that error it hasn't occurrred.

Interestingly enough /proc/cpuinfo still shows all 4 cores of the CPU (Opteron 2373 Quadcore HE) and the functionality doesn't seem to be affected (nothing crashed etc..)

I'm not sure what the issue could be, I wonder if it's the power supply?  It was getting a little whiny/noisy around the time this happened (the pitch it was making is also the beginning stages of power supply failure in my experience).

Failed to load VMMR0.r0 (VERR_SUPLIB_OWNER_NOT_ROOT)
 

In most cases the error above is useful, it generally means /usr or /usb/lib or /usr/lib/virtualbox is not owned by root and this is the cause of the error.

Solution

sudo chown root.root /usr/lib

Go to:
"Server Configuration" -> Basic cPanel & WHM Setup
Scroll to: "Nameservers" (at the bottom)

From there you can set the names of the nameserver and their IPs.
It's very weird and confusing that nothing under IP Functions/DNS has or links to this.

I don't know why but some installations don't have this in the database by default.

To fix it to an:

sudo apt-get update;sudo apt-get install openssh-server

and then it will work

Fatal error: Out of memory (allocated 6291456) (tried to allocate 7680 bytes)

This is usually caused by Wordpress, Drupal or other ridiculously inefficient CMS' out there, as a temporary fix you can increase PHP's memory limit but it's best to find the actual culprit, by disabling add-ons and other scripts etc...

Requirements:

1.) Enter your root wordpress directory.

2.) Download the latest wordpress.zip to it.

#backup your current files just in case

cp -a . wp-current-bk`date +%Y%m%d`

unzip wordpress-3.7.1.zip
rm -rf wp-includes
rm -rf wp-admin
echo y|cp -a wordpress/wp-includes .
echo y|cp -a wordpress/wp-admin .
echo y|cp -a wordpress/wp-content/* wp-content

This is different than Centos 5, you have two services btu they are called "smb" and "nmb".

You need to enable and start "nmb" in order for your samba server to be listed.

chkconfig nmb on; chkconfig smb on


service nmb start;service smb start

DELETE FROM `wp_comments` WHERE NOT comment_author_email IN ('user@hotmail.com','another@hotmail.com')

The above is an example of specific records you type out, but you could also base it on a subquery.

*Note this will delete all comments indiscriminately.

DELETE FROM `wp_comments`
 

To delete all but save specific comments based on "author e-mail use the following".  Add more e-mails below in the same format if you have more.

DELETE FROM `wp_comments` WHERE NOT comment_author_email IN ('user@hotmail.com','another@hotmail.com')

Dell CS24-NV7

Unusually the Virtualization was enabled when I got this server but all the NICs were diabled in the BIOS including PXE boot!

Advanced -> Advanced Chipset Control

PCI Slot 1 Option ROM: Enabled
Onboard LAN1 Control: Enabled
LAN1 Option ROM Scan: Enabled (you need it for PXE boot)
Onboard LAN2 Control: Enabled
LAN2 Option ROM Scan: Enabled

*you will need to reboot and enter the BIOS again before the NVIDIA Boot Agents for the NICs/PXE Agent is visible in the Boot section and boot options.  You'll also need to enter the "Boot section" and hit "x" to enable each one of them for booting and assign them the correct boot order ou prefer.

Boot:

PCI BEV: 2-NVIDIA Boot Agent 277.05 (eth0)
         NVIDIA Boot Agent 277.0547 (eth1) 

When manually running it for some reason it decided to ask for/use the CD as a source which I never set.

Disabling the CD as a source stops this from happening, otherwise apt-get will keep respawning and use 100% CPU.

user the "--spider" switch and you can see what it would do.

VBox/Virtualbox solution to NS_ERROR_CALL_FAILED error

This is likely because you have 2D/3D acceleration enabled and your card doesn't support it.
Eg. you switched video card drivers or video cards that did support it.

The funny thing is that you CANNOT disable those options as they are "greyed" out in the VBox client GUI.
The config file has to be manually changed and fixed with these options "accelerate3D="false" accelerate2DVideo="false"



Here's how you fix it:
1.) Close all instances of the VBox Client
2.) Run the sed command below (replace XP.xml with the path to your VBox machine's configuration file)
*Note I recommend sed because there are actually usually multiple instances where the acceleration is enabled in the config file.

sed -i 's/accelerate3D="true"/accelerate3D="false"/g' XP.xml
sed -i 's/accelerate2DVideo="true"/accelerate2DVideo="false"/g' XP.xml

After the above I didn't get the error and was able to boot.

Or in AdminCP it can be done.

This happened after a customer migrated their hosting and the issue was being unable to access PHP sessions.

Warning: session_start(): open(/var/lib/php/session/sess_3e0oms763m6mrqekdnnmodlhs3, O_RDWR) failed: Permission denied (13) in /register.php(202) : eval()'d code on line 1

Solution: (use the correct ownership/permissions)

chown apache.apache -R /var/lib/php

shuf -n 1 /path/to/your/file.txt

The above will give you a random line from the file using the "shuf" command.

Example:

basename /var/log/messages
messages



As shown above the "basename" utility gives you the end filename separately.

dirname /var/log/messages
/var/log

As shown above the "dirname" utlity gives you just the utility even if you pass it a specific file.

The above two utilities are very helpful in Bash scripting when working with files and directories constantly.

cat Xorginfo.txt|grep -nr "xserver-xorg"

Result:

9:    sudo apt-get remove --purge xserver-xorg
13:    sudo apt-get install xserver-xorg
17:    sudo dpkg-reconfigure xserver-xorg

sedcommand="$line"s
sed -i $sedcommand/.*/"$newline"/ $location

The variable "line" should be the actual line number you want to replace.  The above format is necessary otherwise (to break the "$line"s into it's own variable for it to work.

vmx seems to be the issue
 

Get the new version here that actually works:

https://github.com/haad/proxychains

heredoc=$(cat < stuff here
SETVAR)


sudo mount -o user /dev/sr0 cd

You need the "user" option otherwise non-root or non-owners cannot view the CD and this would make it so no anonymous access to the CD/DVD mount would work.  Note that most distributions including Ubuntu DO NOT work unless you manually mount and share as shown above (I couldn't find any other way in Ubuntu).

On the same OS with the same kernels basically I cannot boot FreeBSD installer, I believe the issue is the host CPU.

One host runs an Intel and works, while an Opteron 2373 does not work despite suggestions from this thread: http://149.20.54.209/showthread.php?t=36761

I've tried cpu options like "kvm64" "Opteron_G3" and none of them worked.
 

The bootloader hangs with the following:

I found the solution based on these threads

forums.freebsd.org/viewtopic.php

freebsd.1045724.n5.nabble.com/amd64-175780-Crash-on-KVM-boot-due-to-xsave-instruction-issue-td5783169.html

You need to specify these cpu options:

-cpu core2duo,-xsave

I couldn't get it to boot with -cpu host and the -xsave (disables the xsave CPU function which is the other cause of the crash).

wget --accept "*.pdf" -r http://somewebsite/page

This happens because of a permissions or ownership issue.

Generally /var/lib/mysql should be all owned by mysql.mysql (check that).

To fix it use chown -R mysql.mysql /var/lib/mysql

Also make sure the files are at least readable and writable by mysql (eg. 700).

Run top then press 'O' (capital letter o) followed by 'p' then 'enter'. Now processes should be sorted by their swap usage.

even setting privvmpages to a specific setting DOES not affect "free -m" in containers.
This is probably a kernel issue

Sipura / Linksys PAP/VOIP/SIP Adapter Issue

Can't receiving incoming phone calls and you're behind a NAT router (99% of people)?

• 1. Login to the adapter.
• 2. Click on "Advanced" (location varies but usually somewhere on top)
• 2. Click on "SIP"
• 3. Scroll down to "NAT" (usually at the bottom).

You'll find 2 columns with 4 rows of drop-down boxes (they're probably all set to no and this is your problem).

Set the first 3 rows in both columns to Yes.

Save the settings and after that you should be able to receive phone calls.

This was caused by some weird dmraid setup which kind of takes control of drives even if they're blank/unused.

1. Check the table.

dmsetup table
ddf1_44656c6c202020201000006010281f0b3f5195b77cf86172: 0 3905945600 linear 8:0 0

ddf1_44656c6c202020201000006010281f0b3f5195b77cf86172p2: 0 283496448 linear 253:0 1050624
ddf1_44656c6c202020201000006010281f0b3f5195b77cf86172p1: 0 1048576 linear 253:0 2048



2.) Delete the entry

dmsetup remove ddf1_44656c6c202020201000006010281f0b3f5195b77cf86172
device-mapper: remove ioctl on ddf1_44656c6c202020201000006010281f0b3f5195b77cf86172 failed: Device or resource busy
Command failed


*Delete the partitions first (eg. ending with p3 p2 p1 and then delete the main one)

After that mdadm will be happy.

tar -czf yourfile.tar.gz .

The . dot is the crucial part, normally many will use * and that will exclude hidden files by default which is very undesirable as many hidden files are important such as .htaccess and conf files in your home directory etc..  It seems the default behavior of tar should be the opposite but these are all very old tools.

Add this to htaccess:

Options +Indexes

After that people will be able to browse files and directories of your site.

This is a great way to upgrade your RAID array or move it/copy it to a new set of hard drives.

Eg. you have a current RAID 1 array on older/slower drives.

Just add at least 1 of the new drives to the array, update grub/install it and then boot into it.  Then you have a transparent data migration that is fully synchronized.

mdadm --grow /dev/md126 --raid-devices 3


     
md127 : active raid1 sdc1[3] sdb1[0] sda1[1]
      153599936 blocks [3/2] [UU_]
      [>....................]  recovery =  0.8% (1281216/153599936) finish=119.7min speed=21202K/sec
 

 guestmount -a yourimage.img -m /dev/sda1 --ro /mountpoint

Change "yourimage.img" to the actual disk image.
Change "/dev/sda1" to the device on the disk image you want to mount.
--ro is specified only if you don't want write access (good to ensure you don't mess anything up if you just want to recover data).

echo 120000 >/proc/sys/dev/raid/speed_limit_min

This will increase the speed, note that sometimes a rebuild is slow due to current disk activity/iowait.

If that is not the cause then you may have a hardware issue (controller, cable or a bad drive).

Basically these cards are a stripped-down version of Dell Perc 6/i only  they (SAS 6/ir) support JBOD.

The Dell Perc 6/i are basically useless because it doesn't have JBOD support and requires software or BIOS commands to add or remove any hard drive-defeating the purpose of hot swapping convenience and ease).  I tried loading other firmware to the 6/i's but it wouldn't work or boot with Dell's Perc BIOS.  I tried using other methods which actually bricked the Perc 6/i (never try those ones that erase the BIOS first without testing to see if the program that writes the new BIOS can actually detect your card!).

date -d @timestampgoeshere +%c

It's very handy and simple as shown above.

I read this article and still don't understand the issue.

If I understand correctly the client negotiates after the first SSL connection and then gets the correct hostname and thus correct certificate.

http://wiki.apache.org/httpd/NameBasedSSLVHostsWithSNI

To their credit I know I'm not using SNI becuase I get this message in the Apache log :)

[warn] Init: You should not use name-based virtual hosts in conjunction with SSL!!

But once again I don't get the issue.  SSL works fine with my name based vhosts and allows me to use a shared certificate by default and if I want a "real certificate" I just buy another IP from my provider, assign it to the right domain and buy the new certificate and set it up.

To put it in perspective I've used this for years on my own manual websites, using Name Based vhosts and a shared SSL certificate AND sites with separate IPs that have their own without issue.  SNI sounds like it is not as widely as supported by clients as normal SSL connections.

I guess the only real benefit of SNI is the ability to serve multiple unique certificates without a separate IP being required, but I don't see this being an issue for most people unless they're on a real budget.

I do agree at some point in the future it may be a problem, but by then IPV6 should be widely adopted and IPs will no longer again be an issue.

Visit the above URL, choose your version and architecture and install it.  EPEL has a lot of missing and extra packages that rpmforge does not.

Everyone should be running with safe_mode on in /etc/php.ini (on Centos) as it makes exploiting your system more difficult is PHP can't execute anything on the system if a script is exploited.

For example with Safe_Mode on the only executable files on the system are ones in the safe_mode_exec_dir = /safephp

This is crucial, if you must execute anything from PHP then you have to copy the binary and assign to the user that Apache runs your site under.  This makes things much more secure.

130917 17:57:09 [ERROR] Fatal error: Can't open and lock privilege tables: Incorrect key file for table 'user'; try to repair it

Solution

Restore a proper user.* file for mysql and restart

PHP5 Centos 6 displays part of code from PHP file for some scripts

Solution

edit /etc/php.ini change  short_open_tag = Off to:
short_open_tag = On

Then restart Apache and it should be resolved (assuming the scripts failing used )
