Re: Reconnect to a specific TTY session?
Then the dropped ssh connection had not caused the ssh daemon to terminate yet, and the screen session was still attached... usually screen only offers to reattach detached sessions. Well, that's the point of screen, it doesn't terminate when parent terminates. Plus you can detach screen that is running with -d, and attach it back with -r Regards, Atis -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

For per user settings use .screenrc If you use the command line a lot for certain applications, why not put them in your .screenrc and run screen all the time. If you log in and often and think you might forget then put screen on a line on its own at the end of your .bash_profile + .bashrc files.

It's been some time since I used screen so I'm not sure what the above options are, but your problem is that you start screen in the shell and when ssh dies the shell dies and takes with it all it's children. One solution I can think of is to start screen as a background process (server screen). Not sure if 'screen ' is enough or you may need to use the 'at' command. You can then start another screen session to connect to the original. This one will die on exit but leave the master running. There may may be a command line option for this, possibly then one mentioned above (I don't have it installed at the moment so I can't check) -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
