First of all, we have a firewall that only allows certain people to access the computers that are set up on it. So in order to access the other computers, they must SSH into the firewall macine and then rlogin or telnet to the others. No one has any problem SSH'ing into the firewall. There are 5 computers that they can connect to from there, all of them Alphas. 4 of them work just fine, the other has problems and they've just started happening recently. It's an AlphaPC running RedHat 6.2. It's very random as to when this happens but sometimes you will trying to login to it and it will just say disconnected and won't allow you to login. This machine has worked fine for months and no changes have been made to it or to the firewall settings that I am aware of. Does anyone have any ideas as to why it is doing this? Thanks in advance.
