dhcpd question

[Joe Clever]

Igor,

I think all you need to do is specify the interface name on the 
command line, i.e. "dhcpd eth1". I see this in the startup scripts 
on my standalone firewall, and the dhcpd man page says :

The  names of the network interfaces on which dhcpd should 
listen for broadcasts may  be  specified  on  the  command 
line.   This  should  be  done  on  systems where dhcpd is 
unable to identify non-broadcast  interfaces,  but  should 
not  be  required on other systems.  If no interface names 
are specified on the command line dhcpd will identify  all 
network  interfaces which are up, eliminating non-broad­ 
cast interfaces if possible, and listen  for  DHCP  broad­ 
casts on each interface.

It also sounds like you need to assign an IP to eth1.

Joe

Hi there. I can't specify a broadcast for eth1 because eth1 has no ip
address. Eth1 is the interface that is supposed to be connected via the
switch to the masqueraded machines. So what I need dhcpd to do is listen
for any requests from the inetnral machines on eth1 and assign the range
of ips given in the subnet declaration. In case anyone needs it, the
message I am getting immediately after starting dhcpd is: Internet
Software Consortium DHCP Server V3.0.1rc9
Copyright 1995-2001 Internet Software Consortium.
All rights reserved.
For info, please visit http://www.isc.org/products/DHCP
Wrote 0 leases to leases file.

No subnet declaration for eth0 (68.37.217.155).
** Ignoring requests on eth0.  If this is not what
   you want, please write a subnet declaration
   in your dhcpd.conf file for the network segment
   to which interface eth0 is attached. **


Not configured to listen on any interfaces!

Does anyone know how I can specify eth1 as a listening interface on the
command line perhaps? Thanks!
