Session "hijacking" - Recover lost session

Hi Guys,

Is there a way to recover a lost session? I was working in a server and that lost the connection, now, I have a new session but all the previous processes that I was running, like scripts, etc, are still running.

Is there a way to bring them to my session?

Best regards,

Marco.

I dono't think so, which is why I prefer to have an Xvnc on each UNIX box. If I lose connection, or go home, I just reconnect to my vnc desktop. Depending on settings, two or more can connect to same desktop. If a box is rebooted or crashes, I lose only the local desktop.

You can tusc/truss/strace into your old processes, if you want to try to collect output of such. This generally slows them down. If they start writing to the dead terminal, they may die before you see anything.

For the future, perhaps you should configure a utility called "Screen"

I had forgotten about screen reconnect, thanks.

Both require forethought. However, VNC gives you full X and, rather than an additional step, it is a different tool.

You can always use xming or export your session in case you need it, though you will lose the graphical display in a redirection scenario.
