Nothing's perfect! :-) /* -OT- At my work place, my boss was linux 'fan' when I started as IT admin. I setup corporate Firewall based on FreeBSD 4.3 - IPFW+NAT and database server on FreeBSD 4.3 with MySQL, Apache and Samba... for the last year we have in practice '0' (ZERO) downtime - 99.99% Level of Service. Not bad, ah! I wish to see Linux box making less then 2 minutes downtime for one year! Because of this I just changed M$ Windows NT 4.0 Server based on DELL PowerEdge 2400 with FreeBSD 4.6 - samba as FileServer! My boss asked me to do so... ;-))) */ It may be just a bug into build in FreeBSD 4.6 DHCP client. Altough, I am not sure. Why don't you try to install ISC DHCP from the ports it is under ports/net/isc-dhcp3. There is DHCP server (we use this as DHCP server at my work - works as a charm) and DHCP client, too. Try with that one! > I might try firing up an analyer to watch the packets and see what > the DHCP client is really sending.
