You have to figure out what network(s) will be served by each interface, then use the route command to assign the required route(s) to each interface. If you are operating within a closed network, and you know how to reach all parts of that network, then you may not need any default route. But if you aren't on a closed network (ie; you're on the Internet), or if the network is large and you don't know how to reach all of it, then you will need a default route, and it will have to be assigned to one interface. In either case, if you need the machine to continue to serve clients one both networks if one interface goes down, then you need a cron job to run a script that checks connectivity on each network. If the script finds that one network is down, it needs to delete all the routes associated with that interface and assign them to the other interface, then send an alert to a sysadmin. This will only work if all the clients are reachable through either interface. Tony - -- Anthony E.
