Thanks for the previous advice everyone. When I originally installed Red Hat 8.0 I set both as DHCP clients. Now I want them to be static assignments. Here is my issue... /etc/sysconfig/networking/devices contains two files: ifcfg-eth0 & ifcfg-eth1 ifcfg-eth0: DEVICE=eth0 BOOTPROTO=static BROADCAST=10.0.0.255 IPADDR=10.0.0.200 NETMASK=255.255.255.0 NETWORK=10.0.0.0 ONBOOT=yes USERCTL=no PEERDNS=no GATEWAY=10.0.0.1 TYPE=Ethernet ifcfg-eth1: DEVICE=eth1 ONBOOT=no BOOTPROTO=static IPADDR=10.10.10.1 NETMASK=255.255.255.0 GATEWAY=10.10.10.254 TYPE=Ethernet USERCTL=no PEERDNS=no NETWORK=10.10.10.0 BROADCAST=10.10.10.255 When the boxes boot my IP address for each are the same IP addresses specified in the ifcfg-x files above. After some time my Red Hat machines will run a dhcp client and change IP address to my DHCP server range (10.0.0.2 to 50). Configuring my DHCP server to give these boxes a static IP isn't an option (ISDN modem). /etc/init.d/network restart gives me my static IP address on eth0 (eth1 disabled). In /sbin directory I have two files: dhclient and dhclient-script. If I do this: /sbin/./dhclient my eth0 interface will go to DHCP server and get an IP address (eth1 is uncabled) I've spent a few hours looking around on the Internet. I think something is causing those dhclients to run and overwrites my static entries. Anyone know how I can stop *any* dhcp client from running on my boxes? I prefer not to delete the files unless it's necessary. Thanks, Paul
