Dear Michael,

Thanks for your answer. You are absolutely right that the admin is doing
good.

But here is my situation: my professor has no money to buy me a workstation
or a second PC to install Linux. Also it would be difficult for me erase my
current PC's Windows system and change everything to Linux. There are some
utilities that only available in Windows.

I did talk with our admin. They suggested me to unhook network connection
while doing long simulation, thus avoid update and auto-restart.

Now the problem comes back to X-session that can be interruped and resumed:
since "unhook the network" and "auto-restart" are the same problem that I
lost connection to the remote workstation.

How to setup the Exceed, or my SSH, or SecureCRT and/or the remote session
to stay around while the connection is lost temporally?

Thanks for your help,
