Hi all

This is the first time posting to this list so please understand if this quistion has been posted before.

I have one server with 4 ethernet card in all running on 192.168.1.* network what i want to do is run nfs on.

eth2 192.168.1.6 running nfs
eth3 192.168.1.7 running nfs

eth2 would export samething like this /backup then /store.

eth3 would export samething like this /folder3 /folder4

but at this time all I can do is make it work on all of the ethernet cards and only work on the first ethernet card eth0 for all requests.

I have search gooogle and man pages but can not find anything or would I need to do load balancing for this to work?

I have tryed this in the /etc/exports file:
192.168.1.6:/backup 192.168.1.12(rw,root_squash,sync)
192.168.1.6:/store 192.168.1.12(rw,root_squash,sync)
192.168.1.7:/folder3 192.168.1.14(rw,root_squash,sync)
192.168.1.7:/folder4 192.168.1.14(rw,root_squash,sync)

#mount 192.168.1.6:/mad-backup /backup

But when i try to mount it on the client I get a this msg
mount: 192.168.1.6:/backup failed, reason given by server: Permission denied

please help me?

Thank you

Benjamin Jeeves

I believe that your export file is written incorrectly. The export file lists directories to export, you can't use it to specify which interfaces on your server will serve those exports. The NFS service is probably reading your exports file and interpreting 192.168.1.[6|7] as part of the path to export, so when you have a client try to mount 192.168.1.6:/backup, it fails, because /backup isn't actually exported, 192.168.1.6:/backup is. Remove the leading ip addresses from your exports file and restart the service, and your mount will likely start to work just fine.

Hi

So what you are saying is that nfs server will not bind to one or more specify interfaces which would mean that you would have to do load balancing if you wanted it to work over two ethernet card YES/NO? if Yes then where is the best place to start?

Thank you

If you want to do load balancing for your network interfaces, I suggest that you use the bonding driver. It aggregates physical interfaces into one big interface, and allows you to set all sorts of load balancing policies. HTH

192.168.1.7:/folder4 192.168.1.14(rw,root_squash,sync)

That sort of syntax is definitely not supported. NFS shouldn't have to know or care about how you want to organise your network.

If you want to enforce no NFS traffic on eth0, then how about using iptables to block traffic to port 2049 on that interface?

You might then add static routes to 192.168.1.12 and 192.168.1.14 and/or set up iptables rules on the server if you want to enforce which interface those machines are allowed to talk to.

Cheers,
Trond
