How to change ssh-greeting under ubuntu

Every time I connect to my Ubuntu over SSH, I see the same dreary message :

Linux superfast 2.6.20-16-generic #2 SMP Thu Jun 7 19:00:28 UTC 2007×86_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.

Here's how to change it. It will be necessary to edit a couple of files.
The first three paragraphs of this "cart" are here:
/etc/motd
The build number and disclaimer of warranties - the information is not very useful for me, I just replaced it all.
To disable the last login message (which I do not recommend doing), you need to edit this file:
/etc/ssh/sshd_config
Find this option and replace yes with no:
PrintLastLog no
Now, when you enter, you will not see this message. For security reasons, I still do not recommend it.
Here is what my login looks like now:

This is a superfast system. Please max out the cpu accordingly.
