As a System Administrator I will often come across a system error code in a log file and need to look up what it means. I don’t know about you, but I don’t know that error 107 is “Transport endpoint is not connected” off the top of my head. My solution was a small Perl script that will print the error’s meaning or optionally all known error codes and their meaning. The perl code is below this listing of error codes.
