The server I am using is Ubuntu 10.10. To ensure security I want to edit the banner the server sends to the client.
If I telnet to my host on port 22 it tells me the exact version of SSH I am running (SSH-2.0-OpenSSH_5.3p1 Debian-3ubuntu4). The situation is the same with MySQL and Cyrus.
Any suggestions? At least for SSH?
Thanks

Almost universally, identifying banners are part of the compiled code and do not have configuration options to alter or suppress them. You will have to recompile those pieces of software.
