On anything complex, I just do something like this. I'll go into my rc.local and add a command to execute my custom network script, say /etc/net.custom. My /etc/net.custom looks something like this: #------------------------------ #!/bin/bash # First bring up all interfaces ifconfig eth0 ip1 netmask mask1 ifconfig eth1 ip2 netmask mask2 ifconfig eth0:0 ip3 netmask mask3 #build routing table manually route add -net net1 netmask mask1 some-routers-ip route add -net net2 netmask mask2 route add -net net3 netmask mask3 route add default gw ip1 #firewall ipchains -F #-------------------------------- It's not standard but I find it easier to manage than all the /etc/sysconfig/network-scripts/ifcfg*'s. All my network hacks are in one file that I can just /etc/net.custom (did you know tab completion doesn't work in e-mail?) and squash all the errors until I get it right. While we're on the subject, how do you flush the routing table? I do a 'route -f' and it just returns the help screen telling me that a 'route -f' should do the trick. Odd. -Brian
