ls -ld /var/run/screen/
drwxr-xr-x. 3 root root 60 dic  6 12:23 /var/run/screen/

chmod 777 /var/run/screen


Note: The folder was changed to 777 prior to reboot

Can you please check that your screen binary has correct permissions?

-rwxr-sr-x. 1 root screen 475072 Sep  3 10:36 /usr/bin/screen

Sorry for the delay but I didn't had this computer at a hand, the file has incorrect permissions, I've reverted it to the ones you listed, so I'm closing the case.

Thanks!
Pablo

This happens for me on Fedora 19.

$ screen /dev/ttyUSB0 115200
[screen is terminating]

strace shows the last error to be:
write(1, "Directory '/var/run/screen' must"..., 49Directory '/var/run/screen' must have mode 777.

However it "fixes itself" if I wait a few minutes (without me
taking any other actions).  This is pretty strange.  I wonder
if it's something to do with tmpfiles periodically waking up
and fixing the directory permissions?

$ ll /usr/bin/screen 
-rwxr-sr-x. 1 root screen 471104 Jun 18 15:31 /usr/bin/screen
$ ll -al /var/run/screen
total 0
drwxrwxr-x.  3 root   screen   60 Jun 18 15:31 .
drwxr-xr-x. 47 root   root   1420 Nov 25 13:30 ..
drwx------.  2 rjones rjones   60 Nov 26 11:49 S-rjones

[lnykryn@notas ~]$ cat /etc/tmpfiles.d/screen.conf 
# screen needs directory in /var/run
d /var/run/screen 0775 root screen

So systemd-tmpfiles can create that dir with correct permissions. But I think that that error message is a little bit misleading and maybe should be changed. And also I am not sure why that configuration file is put into /etc it should be in /usr/lib/tmpfiles.d

I see the same on my machine. I fedup'ed today from FC17 to FC19. It worked fine in FC17. Now it does not (waiting does not help). On my Laptop (also FC19) everything is fine. Permissions are identical to the non-working machine.

I run screen without any parameters. The output and strace looks like Richards output.

Hi,

i may have found the solution :)
my screen was exiting with [screen is terminating] like in this ticket and in:
-http://unix.stackexchange.com/questions/93892/screen-is-terminating
-https://bugzilla.redhat.com/show_bug.cgi?id=725886
-https://bugzilla.redhat.com/show_bug.cgi?id=813607
-https://bugzilla.redhat.com/show_bug.cgi?id=828174
-https://bugzilla.redhat.com/show_bug.cgi?id=844167
-https://bugzilla.redhat.com/show_bug.cgi?id=845671

i was having these lines in my /etc/fstab (it's a dedicated server so it's not a standard install of Fedora 19 from the cd)

proc           /proc   proc    defaults                0       0
sysfs          /sys    sysfs   defaults                0       0
tmpfs          /dev/shm        tmpfs   defaults        0       0
devpts         /dev/pts        devpts  defaults        0       0
dev            /dev    devtmpfs        rw      0       0

so /dev/pts was mounted like:
devpts on /dev/pts type devpts (rw,relatime,seclabel,mode=600,ptmxmode=000)

instead of:
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,seclabel,gid=5,mode=620,ptmxmode=000)

just remove all the unneeded lines in /etc/fstab and reboot

--- Additional comment from Rolf Offermanns on 2013-12-20 07:45:01 EST ---

For a fix without reboot (if you can't reboot right now):
sudo mount -o remount,gid=5,mode=620 /dev/pts

Well, finally screen.conf file is located in /usr/lib/tmpfiles.d directory.

scm-commit for F20 (http://pkgs.fedoraproject.org/cgit/screen.git/commit/?h=f20)
scm-commit for F19 (http://pkgs.fedoraproject.org/cgit/screen.git/commit/?h=f19)

It should fix the problem. Hopefully.
