I have a laptop which I either use with it's building 802.3 port, or with it's 802.11b port.

I have it configured to get it's IP address from a DHCP server running on RH9. The server gives it a different address depending on which port I use.

Is there a way I can tell the DHCP server that the ports both belong to the same machine and they are mutually exclusive (ie, it will never see them at the same time).

I tried to add this :

host laptop.sub.top {
hardware ethernet xx:xx:xx:xx:xx:xx; #en0 802.3
hardware ethernet yy:yy:yy:yy:yy:yy; #en1 802.11b
fixed-address 192.168.0.250;
}

but it had no effect - I see in the man page, it references this but in relation to bootp, not dhcp.

I would also like to be able to assign a name to the 802.11b WAP I have; it is just acting as a bridge at the moment, but it still has an IP address. How can I do that?

maybe it would be more 'correct' to assign a different host name to each of the interfaces on my laptop, then it wouldn't matter if it were given a different address.

I wonder how I can do this on Mac OS X.3.3?

The problem is that I cannot send email to our smtp server because it cannot do a reverse lookup on my 802.11b interface.
