[wplug] Using a specific DHCP server?

Good to hear.  For future reference, I found one other option, ebtables,
that might work.  ebtables was designed for configuring complex bridging
but I suspect it can be used to allow/deny Ethernet frames as you wish.

	That did the trick..  A rogue DHCP server is exactly my problem,
and stopping it is outside of my control for the time being.  This is
all just a temporary setup, so this will work just fine.
	
	Thanks all for the help! 
	
	

		You can also put a setting in dhclient.conf to ignore
DHCP replies from specific ip addresses.  Again this isn't ideal.
		 
		        reject ip-address;
		 
		       The reject statement causes the DHCP  client  to
reject  offers  from
		       servers  who  use the specified address as a
server identifier.   This
		       can be used to avoid being configured by rogue or
misconfigured  dhcp
		       servers,  although  it  should be a last resort -
better to track down
		       the bad DHCP server and fix it.
