nfs

i have two RHEL5 boxes on a private network together (192.168.2.0/24) and I am trying to export a file system from one to the other but I keep getting the following error:

mount.nfs: Input/output error

on the client side I see this output:

mount: trying 192.168.2.101 prog 100003 vers 3 prot tcp port 2049 mount: trying 192.168.2.101 prog 100005 vers 3 prot tcp port 960

and on the server side I see this:

Sep 20 14:14:32 omicron mountd[18739]: authenticated mount request from 192.168.2.87:635 for /srv/nfs/web (/srv/nfs/web)

but that's all. I opened up iptables so that the whole 192.168.2.0/24 network is allowed to communicate freely but the public side is locked down to 22,80 etc....

any ideas?
