No Sockets found in /var/run/screen/S-root. when using `screen`

Question

I want to screen on a machine with fedora the result is:

   [root@kitch udp]# screen -ls
    No Sockets found in /var/run/screen/S-root.

    [root@kitch udp]# screen -ls listen_for_exception
    No Sockets found in /var/run/screen/S-root.

how to deal with this? thanks

Don't use -ls. -ls tells screen to print out a list of open screen sesstions, and then quit. It's complaining about "No sockets" because you do not have any screen sessions running. Try:

screen -S listen_for_exception
