After upgrading some servers to Debian Linux 6.0, from time to time I find the server hostname reset to (none). How could I track what process does that and avoid this situation?
I am a programmer, not an administrator. As I don't know all the specifics of Linux, I am using Virtualmin and Webmin to administer those servers.
You should follow HowTo/ChangeHostname - Debian Wiki and set it to whatever you want, however it sounds like Webmin and/or Virtualmin is misbehaving (try to update it to latest version, if problem still there you might want to submit bug report).
