I have a fresh install of Ubuntu Server 10.04 and all is well when using the local term. However, when I use ssh to admin it remotely (it is on the same switch and in the same room) I can login and work for about 2 min. Then the term just stops responding, no errors, nothing. The server is still working fine.
If I kill the terminal and open a new one then login again all is well for another 2 min.
