Hi,
The truth of the matter is that I never want to twiddle with the
lease file either. Our network head has (numbly IMHO) set the
default lease time to 30 days for areas like dorm rooms. The rest
of us have been arguing that it is too long; a week max would be
better. Then he comes to me two weeks after the end of the semester
and says "we need to clean out the leases in subnets x, y, z because
the students are gone and summer programs are about to begin, and
we don't have enough free leases." Doh! I told you so! Hence the
birth of my script. Then it got modified to ping for machines still
active, etc, etc.
This really doesn't have anything to do with netreg, since the MAC
addresses have to be whacked from the dhcpd.conf too; you are right.
I consider it a major flaw in ISC dhcp that you can't set a "drop dead"
date in the future with it. A method of specifying in the dhcpd.conf
file that "no lease will go beyond this time in the future, and no
new leases will be handed out after that time". Such a feature would
have its uses.
