How to Enable or Disable Login Messages

I do a lot of remote remote maintenance via ssh on my machines and one thing that I’ve long wondered about is the message outputted when you login.  You know, the system information output plus the notice concerning the warranty, etc.  Here is the output I’m referring to when connecting to my Sun Sparc Ultra 10 server via ssh:

 

Linux sparc 2.6.15-51-sparc64 #1 Tue Oct 23 21:46:00 UTC 2007 sparc64 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.
Last login: Sun Dec  9 12:50:43 2007 from 192.168.0.6

Now, that information is not ultra annoying by any means, but sometimes after repeated connections I just really don’t want to see it.
