Dear managers,

Thanks Tim, Andrew, Daniel,  Musin for your responses. I had mixed responses
however. Some agree that a simple change in /etc/hosts for hostA and hostB
on hostB and hostA respectively would help, and I do not need to restart
anything: "Changes to /etc/hosts take effect immediately, or as soon as the
nscd daemon updates." I also learnt that gigabit performance on NFS might
not all that great.

Most recommend that I specify a separate IP in /etc/hosts for each different
interface. However, I already have an existing list of ldap users with
autohome specified to hostname. Instead
of going through all of them and changing it to another hostname, I wanted
to know if just changing just one hostname in /etc/hosts will be equivalent.

I realise some things like email services (namely smtp in my case) and
scripts defaulting to hostname (rather than fullname hostname.domain) might
have problems. I can easily change this, but am I missing anything big here?
(my nsswitch.conf is set to files, dns...)

Another question...if what I originally thought of is ok, do I need to do
share/unshare or mount/umount in hostA and B, or will the routing happen
automatically?

Thanks very much for your advices and for bearing with my silly questions :)

Original Q:

Dear managers,

Just wanted to confirm...I have serverA automounting from serverB. I'd like
to specify them to use a 2nd gigabit network interface between them...I was
thinking of just modifying /etc/hosts of serverA and serverB respectively to
know their corresponding host names as the ip address of the 2nd interface.
This should work right? Do I have to restart things like nfsd in this case,
or would it route automatically?

TIA:)
