Setup Basic Ubuntu Mail Server

If you are like me when you setup a new Ubuntu Server, you select SSH when prompted at the end. If you would like to setup a basic mail server using Postfix and Dovecot, all you need to do is run tasksel mail-server as root or using sudo.

Unmountable Boot Volume Windows XP

If you ever receive this error in Windows XP or Server 2003 this will typically fix the problem.

1. Boot to a Windows Installation CD
2. Press R to enter recovery console.
3. Run chkdsk /p
4. If it finds errors run chkdsk /r (I don't recommend running this, unless it finds errors, as it takes a lot longer to run).
5. Run fixboot, then press y.

This should resolve the problem, at least it has for me.

Ubuntu Virtual Server Cloning

If you have ever cloned an Ubuntu server machine, you may have noticed that you now have eth1 instead of eth0.  Another issue that commonly happens, is eth devices aren't even recognized as you change MAC addresses for the virtual network devices.  To stop this from happening, run these 2 commands as root before exporting the base hard drive.

• rm /etc/udev/rules.d/70-persistent-net.rules
  
• rm /etc/udev/rules.d/75-persistent-net-generator.rules
  

This will stop Ubuntu from regenerating eth devices for each new mac address that you generate, making the image that much more generic and portable.
