4 # Kerberos Ticket Checker
5 #
6 # This script is handy if you allow kerberos tickets to expire
7 # on your nodes. The script will simply warn you when a node has
8 # kerberos tickets expiring on the current date. This will allow to
9 # re-initialize the tickets if you wish to do so.
10 #
11 # Nothing fancy here, all Nagios will show is the number of tickets
12 # that are going to (or already have) expired.
13 #
14 # An item of note:
15 #
16 # We made no provisions for the weekend. If tickets expire on the
17 # weekend and nobody is around, you won't see a warning on the
18 # Nagios console because we look for expired on the current day
19 # only. It's a good idea to have this warning emailed to the
20 # appropriate admin and if there is something critical that relies
21 # on Kerberos, you might want to send a page.
