dpkg -l | grep service will show the enabled modules for that service. -s | packagename shows the version available. 64 bit on Debian is called amd64, not x86_64
32bit on 64bit
To use 32bit applications on Ubuntu 10.04 64bit you will need the following package: ia32 libs

apt-get upgrade option
bind9 fails to start
ubuntu none:0: open: /etc/named.conf: permission denied
The below fix is not related to the above error in the box.
This can be caused because the Operating System is Ubuntu 12 (as of 28/01/13), and there is a bug with Plesk version 11 servers.
cd /etc/apparmor.d/disable ls -lah ln -s ../usr.sbin.named .
Restart apparmor by doing one of the below:
/etc/init.d/apparmor restart service apparmor reload
or it could be this. Then restart bind:
/etc/init.d/bind9 restart

Follow the above guide and then before you get to starting ezstream section do the following:
FTP your .mp3 music files to /var/www/vhosts/yourdomain.com/httpdocs/FolderOfYourChoice as either files or folders. Folders will work as when you index the files it picks them up anyway.
cp /usr/share/doc/ezstream/examples/ezstream_mp3.xml /var/www/vhosts/yourdomain.com/httpdocs/FolderOfYourChoice/
vim /var/www/vhosts/thesixts.com/httpdocs/mu/ezstream_mp3.xml
Ensure these are set correctly.

Plex

You need to set the Web URL to be http://127.0.0.1:port/web to be able to remotely manage the settings externally.
Once installed to access the panel, go to http://ipaddress:32400/web
If the settings menu disappears, do:
/etc/init.d/plexmediaserver restart

Install Xuggler. Go to http://www.xuggle.com/xuggler/downloads/
cd /usr/local wget http://com.xuggle.s3.amazonaws.com/xuggler/xuggler-3.1.FINAL/xuggle-xuggler.3.1.818-i686-pc-linux-gnu.sh chmod a+x xuggle-xuggler.3.1.818-i686-pc-linux-gnu.sh ./xuggle-xuggler.3.1.818-i686-pc-linux-gnu.sh
Put Xuggler into PATH
vim /etc/profile
Add the following at the bottom of the file
export XUGGLE_HOME=/usr/local/xuggler export LD_LIBRARY_PATH=$XUGGLE_HOME/lib:$LD_LIBRARY_PATH export PATH=$XUGGLE_HOME/bin:$PATH
Install LAMP
apt-get install lamp-server^ phpmyadmin
Install SSL on Ubuntu 12.04 with Apache 2.2.22
This is for a fresh install, unmodified in any way from apt-get install apache2.
a2ensite default-ssl a2enmod ssl service apache2 restart /etc/init.d/apache2 restart
Then go to https://yourhostname (either your domain or IP address), accept the certificate warning and you should see your website.
mkdir /etc/apache2/ssl vim /etc/apache2/sites-enabled/default-ssl /SSLCertificateFile
Press insert and edit the filepath of:
SSLCertificateFile
SSLCertificateKeyFile
SSLCACertificateFile
to direct to your files with the Certificate (.crt format), the Private Key (.key format) and the Intermediate Root CA Bundle (.crt format).
Then vim each of the above filepaths and enter the certificate, key and Chain CA in their respective files.
chmod 600 /etc/apache2/ssl/SSLCertificateKeyFile /etc/init.d/apache2 restart
To mitigate the BEAST attack and disable SSLv3 enter the following into /etc/apache2/sites-enabled/default-ssl
SSLHonorCipherOrder On
SSLProtocol -all +TLSv1
SSLCipherSuite ECDHE-RSA-AES128-SHA256:AES128-GCM-SHA256:RC4:HIGH:!MD5:!aNULL:!EDH
To disable Apache and OS version put the following in /etc/apache2/sites-enabled/default-ssl outside of the VirtualHost tags:
ServerTokens Prod ServerSignature Off TraceEnable Off
/etc/init.d/apache2 restart
Tokens is the header
Signature is the footer
To get 100 on SSL, see HN.

Old Version of Plesk and an update fails
If you get the following error when upgrading Plesk using the updates section in plesk:
Installation could not be started: Unable to install packages because of package dependency problems. Not all packages were installed. ERROR: An error occurred on attempt to install packages. Attention! Your software might be inoperable. Please, contact product technical support.
Check what Ubuntu OS you are running. To do this via command line run cat /etc/issue.
Repositories
The below repository issue most commonly happens on Ubuntu 6.06 as it is out of support now and the repos have changed. Edit the following file by using vim /etc/apt/sources.list
Comment out the old Ubuntu repository list using # (leave any others such as Plesk) and put in the below.
For Ubuntu 6.06 (Dapper Drake):
#Old-Release Sources deb http://old-releases.ubuntu.com/ubuntu/ dapper main universe multiverse deb-src http://old-releases.ubuntu.com/ubuntu/ dapper main universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ dapper-security main restricted universe multiverse deb-src http://old-releases.ubuntu.com/ubuntu/ dapper-security main restricted universe multiverse
If you get the following error via SSH:
Err karmic/main Packages 404 Not Found Err karmic/restricted Packages 404 Not Found Err karmic/universe Packages, 404 Not Found Err karmic-updates/main Packages 404 Not Found Err karmic-updates/restricted Packages 404 Not Found vim /etc/apt/sources.list.d
karmic.list is Ubuntu 9 which many hosters did not offer (hence no mirrors). If you are using lucid (Ubuntu 10), comment out the lines in this file. Apt should now update with no errors.
For Ubuntu 8.04 (Hardy Heron):
deb http://archive.ubuntu.com/ubuntu hardy main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu hardy-updates main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu hardy-security main restricted universe multiverse # Plesk deb http://autoinstall.plesk.com/ubuntu/PSA8 hardy all
For Ubuntu 10.04 (Lucid Lynx):
deb gb.archive.ubuntu.com lucid main restricted universe deb gb.archive.ubuntu.com lucid-updates main restricted universe deb gb.archive.ubuntu.com lucid-security main restricted universe
Note: change mirrors from gb.archive.ubuntu.com to your own/your hosting companies if need be.
Subversion repository guides: 1, 2, 3, 4, 5
Additional repos:
deb http://archive.ubuntu.com/ubuntu lucid universe deb http://archive.canonical.com/ lucid partner
Then run the following afterwards:
apt-get update /opt/psa/admin/bin/autoinstaller
This should provide more information as to which packages are causing the problem. Also try looking in the following log as this should have the info:
#/tmp/autoinstaller3.log Depending what is broken you may be able to force the install or configure the packages: apt-get -f install dpkg -a configure-all
If neither of those fix then rebuild the VPS. Also check if there have been any custom upgrades such as PHP as that can break it.
For Ubuntu 12.04 (Precise Pangolin):

VNC
apt-get install vnc4server vnc4server
You will be prompted for a password. This password will be used to log into the vnc session. After providing a password, you will get output that looks like: New 'IP.IP.IP.IP:1 (laptop)' desktop is IP.IP.IP.IP:1
Take notice of the number after the colon (:), in this case it is "1." Starting the vnc4server will cause a .vnc directory to be placed in your home directory.
vnc4server -kill :1
Open the .vnc/xstartup file for editing.
vim ~/.vnc/xstartup
The file will look like:
#!/bin/sh # Uncomment the following two lines for normal desktop: #unset SESSION_MANAGER #exec /etc/X11/xinit/xinitrc [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic & xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & twm &
Type :wq and hit enter. Uncomment the lines that start with unset and exec. Comment out the lines that start with xsetroot, vncconfig, xterm, and twm.
The final file should look like:
#!/bin/sh unset SESSION_MANAGER exec /etc/X11/xinit/xinitrc [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources #xsetroot -solid grey #vncconfig -iconic & #xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & #twm &
OR
#!/bin/sh unset SESSION_MANAGER exec /etc/X11/xinit/xinitrc [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic & x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & x-window-manager &
Change the permissions on the /etc/X11/xinit/xinitrc file to make it executable. Run the server, install Ubuntu Desktop.
chmod 755 /etc/X11/xinit/xinitrc vnc4server apt-get install ubuntu-desktop
Remember the number after the colon (:). Log into your remote desktop to check the configuration.
