I'm having the same problem. I'd would prefer to have screen log in and see entries using the 'w' command. From the end of 'man screen':
· Screen must be installed as set-uid with owner root on most systems in order to be able to correctly change the owner of the tty device file for each window. Special permission may also be required to write the file "/var/run/utmp".
So, I suid'd /usr/bin/screen. (was sguid)
-rwxr-sr-x 1 root utmp 291K 2005-02-28 16:23 /usr/bin/screen*
$ sudo chmod u+s /usr/bin/screen
-rwsr-sr-x 1 root utmp 291K 2005-02-28 16:23 /usr/bin/screen*
After that I tried again and got:
$ screen -RD
Directory '/var/run/screen' must have mode 755.
$ ll -d /var/run/screen
drwxrwxr-x 3 root utmp 4.0K 2006-01-22 15:08 /var/run/screen/
(looks like 775)
$ sudo chmod 755 /var/run/screen
Same error
Could Not Write /var/run/utmp: No such process
