dnsmasq configuration

Friday, 27 March 2009

	G'day all,
		I've a qustion about the dhcp server configuration in dnsmasq.  The
way I've configured it it is listening on eth1 as it ought, but is
offering on eth0 which it oughtn't.  What have I missed in the
configuration?

# Configuration file for dnsmasq.
#
interface=eth1
except-interface=eth0
dhcp-range=192.168.1.100,192.168.1.199,255.255.255.0,10m
dhcp-option=28,192.168.1.255
log-queries

and /var/log/messages:

How do I configure dnsmasq to offer dhcp on eth1?

Thanks in advance.
