RE: [MLUG - DISCUSSION] AT&T

["McNutt, Justin M." <EMAIL:PROTECTED>]

We (Mizzou Telecom) have found that pump isn't very tolerant of DHCP servers
it doesn't understand.  We usually recommend ISC's DHCP client (dhclient).
Works like this:

/sbin/dhclient -i eth1

With a /etc/dhclient.conf file like this (for AT&T):

interface "eth1" {
        send host-name "c123456-a";
}

--J

P.S.  Ever notice how the hostnames look a lot like old Campus Computing
Showme login IDs?  :-)
