Change SSH Welcome Banner on Ubuntu

Every time I connect to my Ubuntu development server through my ssh client, I receive the same message and I'm getting tired of seeing it, so I decided to change the message to something else.

Here's the message that I get every time:

Linux superfast 2.6.20-16-generic #2 SMP Thu Jun 7 19:00:28 UTC 2007 x86_64

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:

/etc/motd

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:

/etc/ssh/sshd_config

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 a superfast system. Please max out the cpu accordingly.

Linux is really great.
