Hi all,

I'm running a huge task on a Linux server (CentOS), and the interface is displayed locally on a Windows desktop using X-Win32, which crashes after one and half day. Does this mean my task on the server is dead too? Or the server should be able to finish the task and then kill himself?

Is there anyway to detach the session from my desktop machine and just let it run on the server? For now, I have to keep my Windows Desktop running all the time just to keep the session alive.

Thank you.

To determine whether the process is still running on the server you'd have to login and run "ps -ef" and look through the running processes (or grep for more specific information if you know it). Sometimes if a session gets detached from a workstation it is still alive on the server but you have no way of reconnecting (unless you set it up for that beforehand).

There ARE utilities that let you run things from one session and detach then reattach again from same workstation or even another workstation.

If what you opened was a terminal window in X so that you could run a command from command line you should use the "screen" utility. You can see a discussion of screen here:

If what you ran was an actual X application and not a terminal under X there are equivalents which are discussed in this thread:

If you install vncserver and xrdp, you can connect to your server through Windows Remote Desktop Console (mstsc.exe). This allows you to disconnect and then re-connect from anywhere to pick your session back up again.

If you are running a cmd line prog on the server, the simplest way to 'detach' is
screen is handy if you actually need to re-attach to that session itself, as opposed to just letting the prog run on it's own.

Problem solved using nohup /dir/myprog >myprog.log 2>&1 &

but I'm definitely gonna check out the other two.
