I suspect those error messages are related to problems with old Apples
(the machines on that subnet
are almost all Mac OS 9.x). Before we had ISC's dhcpd we had an NT
server that would rack up a
lot of BAD_ADDRESSs. Packet sniffing showed the Apples requesting IPs
like 0.0.1.186.
The problem outlined in this thread is dealing with a PC running Win2K,
and there's nothing in
the logs with the address dhcpd is apparently preparing to offer that
PC, ala
lease 10.1.17.234 {
starts 1 2007/05/07 15:31:47;
ends 1 2007/05/07 15:33:47;
binding state free;
hardware ethernet 00:03:47:22:33:44;
uid "\001\000\003Gc\330Z";
client-hostname "joe";
}
I'll go back to the man page and try to find a way to increase the debug
level, or start packet sniffing again.
I'll post anything interesting. Thanks.
