how to set ssh/putty session running in disconnected mode


Hi All,

How can we put ssh/putty session running even after in standby or disconnected mode.

The idea is to have run a long running job from my notebook, which may take 6-8 hours, and if i come next day, there should be interrupt with it.

Regards,
Amir

Not sure this or anything will work with the server in standby mode but here is a workaround to Keep Your Linux SSH Session From Disconnecting.

Hope this helps,

Ian

I think what you might need is Screen (or link here)

good luck

I assume the OP means if the client is disconnected from the server.
The screen command will allow the client to disconnect without the running process being stopped.

If you're trying to keep the SSH connection from disconnecting, try the link iChase posted. Otherwise, check out screen (from lithos' post) or the "nohup" command.

I haven't used screen that much so can't comment on that, but nohup is pretty easy. Simply put "nohup" before the command and it will continue to run even if the session is disconnected.

Code:
# nohup somecommand
nohup: ignoring input and appending output to `nohup.out'
This will keep the command running and put all of the results to a file called 'nohup.out' in your current directory ...

Re nohup; I usually use
Code:
nohup /dir/prog > /dir/prog.log 2>&1 &
dir spec may be optional depending on your PATH and where you want the log

Good call. Otherwise all of the error info (everything on stderr) won't be seen.
