Example #1: [root(2)@ironclad RPMs]# screen -r rawhide There is a screen on: 12107.rawhide (Dead ???) Remove dead screens with 'screen -wipe'. There is no screen to be resumed matching rawhide. [root(2)@ironclad RPMs]# screen -wipe There are screens on: 12107.rawhide (Remote or dead) 12410.mirror (Remote or dead) 2 Sockets in /root/.iscreen. Example #2: [root(2)@ironclad RPMs]# screen top <detach> [root(2)@ironclad RPMs]# screen -S top top <detach> [root(2)@ironclad RPMs]# ps ax | grep top 5223 ? S 0:00 SCREEN top 5224 pts/3 S 0:03 top 5228 ? S 0:00 SCREEN -S top top 5229 pts/4 S 0:02 top 5237 pts/2 S 0:00 grep top [root(2)@ironclad RPMs]# kill -9 5223 5228 [root(2)@ironclad RPMs]# screen -ls There are screens on: 5223.pts-2.ironclad (Dead ???) 5228.top (Remote or dead) Remove dead screens with 'screen -wipe'. 2 Sockets in /root/.iscreen.

Does this problem persist in the latest screen-3.9.4 from Raw Hide?
Comment 2 Jeff Johnson 1999-08-23 23:35:59 UTC
Yes, the problem persists in screen-3.9.4.
Comment 3 Jay Freeman 1999-08-25 05:22:59 UTC
Sorry, have had a hard time checking e-mail lately, upgraded my motherboard and luck would have it my harddrive went bad too. From what I can tell, the problem is simply in how screen keeps track of information, in the filenames of the pipes. It performs the following check to see if it is a Remote socket or a Dead socket: if (matchlen || (*n == '.' && n && strncmp(HostName, n + 1, strlen(n + 1)) == 0)) Named sockets don't include the terminal nor the hostname in the filename, therefor causing the local hostname check to fail. A possible solution to this is to modify screen to store the name of the screen after (or before, whatever) the existing terminal and hostname data as opposed to replacing it. That way it could perform that check just like it is, and continue to work without MAJOR design modifications. (This might be something for the screen people though since it isn't really a bug as much as a misplaced feature.)

As this is more of a 'feature request' than a bug, we probably won't fix this here - contacting the screen developers would be your best bet.
