I am running solaris 10 on 3 different workstations
each have modems on serial ports "a" and "b"
Somehow after power outages the permissions on the following files get changed. This causes restricted access to the modems based on the permissions.
As root, I cannot change these permissions to make the modems accessible again. Can someone explain the "c" that is returned with the "ls -l" command output? And, can you help me understand how or where these permissions are set and how to manually correct this?
Machine names are sun0, sun1, sun2
these are device files with symbolic links that point from other places and they control "cu" and "ppp" modem access of users on the workstations.
A great teacher, does not provide answers, but methods to teach others "How and where to find the answers"
