My VNC/NX/ssh session freezes almost every 2-3 minutes. When that happens I cant do anything except for moving the mouse pointer which also doesnt move on the remote machine. I cant type or do anything. Which is very annoying. I am running red hat 5 with gnome 2.16. Please help find a solution to this problem.

What your logs say?

Where do I check the logs?

logs are under " /var/log "

to sort so the last one is the last updated log file.

Thank you for replying again. There are so many logs present in that directory. Which one do I check?

Post your output please
