[ILUG] dhcpd.. machine gone haywire

[ILUG] dhcpd.. machine gone haywire

There's a machine on the local network looking for an IP via dhcpd. It
keeps looking for the same IP.

I tried to ping the IP but it doesn't exist so it's not listening to the
DHCP server. Nobody has complained that their machine is off-line so I'm
baffled as to what machine is causing the trouble!

Here's some log file stuff.

Apr  5 16:28:21 mail dhcpd: DHCPREQUEST for 192.168.1.66 from
00:00:21:ce:fe:dd via eth1
Apr  5 16:28:33 mail dhcpd: DHCPREQUEST for 192.168.1.61 from
00:00:21:db:01:2c via eth1
Apr  5 16:28:33 mail dhcpd: DHCPACK on 192.168.1.61 to 00:00:21:db:01:2c
via eth1

192.168.1.66 is the troublesome host obviously.

Hmm.. snort is giving some interesting readings..

Donncha.
