possible small bug in ltsp/dhcpd.conf

[Gavin McCullagh]

Hi,

I'm not certain of this so I said I'd email and ask before reporting a bug.
Our dhcp server ran out of leases today.  Thanks to logcheck I got a
notification and was able to fix it.

However, when I looked in /var/lib/dhcp3/dhcpd.leases I could see a large
number of leases going right back into 2006 which were using up the
available ip space.  

Should the /etc/ltsp/dhcpd.conf not contain some lines to expire these,
like:

default-lease-time 600;
max-lease-time 7200;

Perhaps I'm wrong, I'm not an expert on dhcp server config.  One way or
another with only 30 machines up on the network we really shouldn't have a
block of 150 leases used up.
