This report is sent to standard output by +default, but see B<-m> below. + +The classifications of principals are determined by a set of patterns at +the beginning of this script. Modify it to add new classifications. + +=head1 OPTIONS + +=over 4 + +=item B<-h>, B<--help> + +Print out this documentation (which is done simply by feeding the script to +C<perldoc -t>). + +=item B<-m>, B<--mail> + +Rather than printing the report to standard output, send the report via +e-mail to the address set at the beginning of this script and also archive +a copy under F</afs/ir/dept/itss/infrastructure/reports>. + +=back + +=head1 FILES + +=over 4 + +=item F</afs/ir/dept/itss/infrastructure/reports> + +The root directory for archived reports. Archived reports will be saved +under this directory in a subdirectory for the year, the month, and +C<kerberos>, under the name C<wallet>. In other words, for a report run +in March of 2003, the report will be saved in the file: + + /afs/ir/dept/itss/infrastructure/reports/2003/03/kerberos/srvtabs + +=back + +=head1 NOTES + +Considerably more information could potentially be reported than is +currently here. In particular, keytabs that have never been downloaded +are not distinguished from those that have, the number of keytabs +downloaded is not separately reported, and there aren't any statistics on +how recently the keytabs were downloaded. These could be useful areas of +future development. + +=head1 AUTHOR + +Russ Allbery <rra@stanford.edu> + +=cut |
