FreeBSD DHCP client not working with dynamic DNS

2004-11-08 Thread Gerard Samuel 
Box 1:  Firewall/DHCP Server/DNS (FreeBSD 5.3)
Box 2:  DHCP Client (FreeBSD 5.3R2)
When I boot Box 2, it gets its IP address, but DNS doesn't
get updated, so Box 2 is unknown to the LAN via its hostname.
If I boot a windows box (tested with 2000/XP), and I've tested with a
networked printer, they get an IP address, and DNS is updated
for those devices.
Any help would be appreciated.
Thanks

Add 'send host-name gladiator;' to /etc/dhclient.conf or if you want to be 
more correct:
interface em0 {
send host-name gladiator;
}

Dont forget to change the em0 interface to what your interface really is.

Worked like a charm.
