I'm running RHEL5.5 and have several network interfaces (eth0, eth1, eth2) on the machine. I wish to make /sbin/dhclient bind its UDP port 68 on specific interfaces (eth0 and eth2) but when I do 'netstat -anp | grep 68' I see:
udp 0 0 0.0.0.0:68 0.0.0.0:* 6109/dhclient
which interferes with another software daemon running its own DHCP client that wishes to run on a specific interface (eth1) not serviced by /sbin/dhclient
Can I get /sbin/dhclient to not bind to UDP port 0.0.0.0:68?
I have configured /etc/dhclient.conf to only service the interfaces I want (eth0 and eth2 in this case) but it still binds to 0.0.0.0:68 which prevents the custom DHCP client from running on eth1.
Any help appreciated, thanks.
