hrm, thanks, but this doesn't seem to work:
`ifconfig xl0 down` doesn't do anything... executes without error, but the
interface stays up.
`/sbin/dhclient` gets a new IP, but doesn't "re-do" the firewall with new
IP, so everything is broken.
echo nameserver 123.34.45.67 > /etc/resolv.conf
echo nameserver 321.23.67.328 >> /etc/resolv.conf
This is over written on startup/reboot by the dhcpclient. If I modify the
file, then it tries to "correct" it self and over writes the file with the
DNS servers provided via the DHCP server.
Any other ideas?
Thanks,
Jack

Hi
To get a new ip
Do
/sbin/ifconfig ethX <use correct number> down
/sbin/dhclient # to get a new ip..
Then for resolv.conf
echo nameserver 123.34.45.67 > /etc/resolv.conf
echo nameserver 321.23.67.328 >> /etc/resolv.conf
