Hello!

Is there any way to specify what local IP address an NFS
client uses to mount an NFS server?

For instance, if I have eth0 with IP 192.168.1.6 and eth1
with IP 192.168.1.7, how can I make sure that a particular
mount point is accessed via 192.168.1.7?


NFS doesn't know anything about ip packet routing. That is a networking
issue.

When a socket is created, you can optionally bind to local IP, interface and/or
IP-Port. Somewhere, NFS is opening a socket I assume? So, is there a way to
ask it to bind?

You can then use this source-IP to convince the routing logic to use a
particular interface (ie, the interface with that IP on it).

Thanks,
Ben
