Re: [screen-devel] [screen is terminating] version screen-4.0.3-16.el6.x86_64

[Kumar, Amit]

Dear All,

Any idea how can I troubleshoot this?
I straced this process and found the following:

tracescrenn.11817:chown("/dev/pts/20", 0, 0)              = -1 EPERM (Operation 
not permitted)
tracescrenn.11818:setpgid(0, 11818)                       = -1 EPERM (Operation 
not permitted)

Any thoughts on this?
Looking at the source of screen.c
.....
.....
  if (ServerSocket != -1)
    {
      debug1("we unlink(%s)\n", SockPath);
#ifdef USE_SETEUID
      xseteuid(real_uid);
      xsetegid(real_gid);
#endif
      (void) unlink(SockPath);
#ifdef USE_SETEUID
      xseteuid(eff_uid);
      xsetegid(eff_gid);
#endif
    }
  for (display = displays; display; display = display->d_next)
    {
      if (D_status)
        RemoveStatus();
      FinitTerm();
#ifdef UTMPOK
      RestoreLoginSlot();
#endif
      AddStr("[screen is terminating]\r\n");
      Flush(3);
      SetTTY(D_userfd, &D_OldMode);
      fcntl(D_userfd, F_SETFL, 0);
      freetty();
      Kill(D_userpid, SIG_BYE);
    }
  /*
   * we _cannot_ call eexit(i) here,
   * instead of playing with the Socket above. Sigh.
   */
  exit(i);
.......
.......
====
It seems to be that either I am not able to open the socket for some reason, 
which is surprising because I am a root user while I try this. Other 
possibility is it has to do something with the display? Any idea on what kind 
of display does screen reply on?

Any help is greatly appreciated.
Thank you,
Amit


Dear Screen,

[screen is terminating] for both Root and regular user ...

Running into this strange problem on a handful of systems. It works great on 
some of our other systems with the same version of OS etc.,. I have googled 
enough with various suggestions and solutions to this problem but none has 
worked for me. And I am ready to pull all hairs out....
Hope I can find some peach with this oddity.

RHEL6 OS
# screen -v
Screen version 4.00.03 (FAU) 23-Oct-06

I have made sure my fstab has this line:
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
$ getent group 5
tty:x:5:

$ ls -ld /var/run/screen
drwxrwxr-x. 3 root screen 4096 Jun  8 11:20 /var/run/screen
$ getfacl /var/run/screen
getfacl: Removing leading '/' from absolute path names
# file: var/run/screen
# owner: root
# group: screen
user::rwx
group::rwx
other::r-x


$ ls -ld /usr/bin/screen
-rwxr-sr-x 1 root screen 387488 May 20  2011 /usr/bin/screen
$ getent group screen
screen:x:84:

Any help here is greatly appreciated.
Thank you,
Amit
