    can't do "screen" as normal user


    I'm having some problems with my Debian server since I updated today.

    When logged in as normal user, I can't do screen anymore:
    web<AT>v:~$ screen
    Must be connected to a terminal.
    web<AT>v:~$ tty
    not a tty
    When switching to root, everything works fine:
    v:~# screen
    [detached from 27600.pts-6.v]
    v:~# tty
    v:~# ll /dev/pts
    total 0
    crw--w---- 1 root tty 136, 13 Nov 17 19:19 13
    crw--w---- 1 root tty 136, 21 Nov 17 20:07 21
    crw------- 1 web  tty 136,  6 Nov 17 20:10 6
    v:~# ll $(which screen)
    -rwxr-sr-x 1 root utmp 364088 Jul 29  2009 /usr/bin/screen
    "su"ing back to a normal user simply reveals the same problem.

    I tried to search for people with the same problem, but did not really find anything except a 10 year old mailing list that claimed clib6 was faulty at that time.

    I checked the apt log for today's update, but there was no libc6 in there.

    Since I don't really know that much about terminals with Linux I have no idea what else to try. Anyone got an idea?


  2. #2

    after some more update/upgrade and a reboot it seems to work again.

    However this time it does either not create new pts when suing or before all this happened my pts had always o+rw permissions.

    Bottom line: It's fixed, I don't know how, as long as it stays this way, i don't care.
