That sounds very reasonable; there's always the possibility that you won't see, within your run time threshold, offers from a rouge server due to race conditions or other crud (slow networks, etc.). Of course, then you have a lot of proactive bogus DHCP Client activity coming from your Nagios system. The best solution of course, but not always the most feasible, is a SPAN port in your core: Simply: $ sudo tcpdump -n -e -vvv 'src port bootps && !ether src 0:50:da:28:37:62' Replace the MAC with your know DHCP server. Matches are rouge. If you see them, get out the jumper cables. ~BAS ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
