My apologies in advance if this question has already been asked or if I use incorrect terminology; I have tried searching for nearly an hour without any luck.

Is there any way to change the active TTY for a session? I was monitoring a long (~5 hour) process through an SSH connection and the network went down. The box is still running the job, but my SSH connection is no longer associated with it.

I tried doing a tail -f on the file descriptor in /dev/pts but get no output. Is there a straightforward way to change my session's pts?

Thanks,
Tres

If the job is no longer associated with a pseudo-terminal then (as far as I know) it cannot be re-attached from outside the process.

Is the process "1" the ultimate parent of the group of tasks?

No, it is still associated with a pseudo-terminal - I'm just wondering how I can set that pseudo-terminal as the active one for my session. Here is one process that was active when the network went down:

How can I set pts/5 as my active pseudo-terminal?

I must admit I don't know.

Traditionally there are the pairs /dev/ptyXX and /dev/ttyXX where one side was the terminal for the program, the other was for a controlling program.

But the /dev/pts/XX come from being created by opening /dev/ptmx, this will create new pairs as required as the previously mentioned mechanism didn't scale.

I don't see how you could open /dev/ptmx and get a previously created /dev/pts/XX.

Thanks for trying! If anyone else has any ideas, I'd love to hear them.
