Hello, I have been asked to setup 2 servers with RH8.0. No problem with this except that each server has 2 NIC's, each with 2 ports on them (4 in total per server). However, the plan is to use one port from each nic and to allow traffic both in and out on both nic's - hence they will be used as a sort of load-balancing and resilience. If one nic fails then the other is still present to handle all inbound and outbound traffic. Each nic port has a real IP address - that is, no private (non-routing) addresses are involved. Both nic's are on the same subnet and have the same gateway.
The problem I am having is configuring the server to do this. Although both nic's are detected by linux, netstat shows only one gateway for one nic. The other nic does not appear in netstat at all. If I configure the gateway as a static host for the second nic, and then a default route to it, these then appear in netstat. However, ifconfig seems to show that most in/out traffic is going through one nic and not the other, so something seems wrong. I would have thought this was a (reasonably?) common enough setup for servers requiring good network performance and/or resilience, but finding out info about it all on the net results in little. I have one document (http://linux.com.lb/mod.php?mod=userpage&page_id=3) which seemed promising, but it involves playing with iptables and iproute2. Do I need to do this, can't I just setup a couple of static routes? I have noticed in the kernel config there is a multirouting option in the advanced server section - I'll have a look at that to see if it helps. Any help configuring this would be appreciated. Apologies for no examples, but if I change the network config at the moment then I'll lose connectivity to the server :-) Thanks, John. ------------------------------------------------------------------------ John Horne, University of Plymouth, UK Tel: +44 (0)1752 233914 E-mail: [EMAIL PROTECTED] PGP key available from public key servers -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
