Customized Welcome Banner in Ubuntu

Every time I connect to my Ubuntu server through putty, I get to see the default message which is kind of scary.
Here's the message that I get every time:

Linux trap 2.6.9-67.0.1.ELsmp #1 SMP Fri Nov 30 11:51:05 EST 2007 i686 i686 i386 GNU/Linux

The programs included with the Ubuntu system are free software;
the exact distribution terms for each program are described in the
individual files in /usr/share/doc/*/copyright.

Ubuntu comes with ABSOLUTELY NO WARRANTY, to the extent permitted by
applicable law.

Changing this message requires editing two different files. The first three sections can be modified by editing the following file:


This file contains the linux build number as well as the Ubuntu warranty message. I don't find this particularly useful, so I removed all of it and replaced it with my own message.

To disable the last login message (which I don't recommend doing), you will need to edit the following file in sudo mode:


Find this line in the file and change the yes to no as shown:

PrintLastLog no

Now when you login, you'll get a blank prompt, although I wouldn't necessarily recommend it because it's useful to see the last login to the system for security reasons. This is my prompt now:

This is development system.
