Hello Everyone,
This topic seems to be a old one but for some reason I am not able to get this
to work.
Sorry for a long post ... wanted to get everything in at once!
Scenario:
Linux NFS server: v3
Solaris 10 NFS Client: v3
Problem mounting a NFS mount point from a Linux Server (CentOS 5.1 Kernel:
2.6.18) to a Solaris 10 Client
My /etc/hosts.allow on Linux Server:
cat /etc/hosts.allow
#
# hosts.allow This file describes the names of the hosts which are
# allowed to use the local INET services, as decided
# by the '/usr/sbin/tcpd' server.
#
portmap: 172.25.30.100
rpcbind: 172.25.30.100
Commands run on Client:
==
Client # mount -o vers=3 -F nfs 172.25.30.120:/scratch/pvfs2 /scratch/pvfs2
nfs mount: 172.25.30.120: : RPC: Rpcbind failure - RPC: Unable to receive
nfs mount: retrying: /scratch/pvfs2
nfs mount: 172.25.30.120: : RPC: Rpcbind failure - RPC: Unable to receive
nfs mount: 172.25.30.120: : RPC: Rpcbind failure - RPC: Unable to receive
# mount -o vers=4 -F nfs 172.25.30.120:/scratch/pvfs2 /scratch/pvfs2
nfs mount: 172.25.30.120:/scratch/pvfs2: No such file or directory <=== This
error is because Linux Server is not running v4 NFS hence a valid one.

also tried to run Snoop on the client and wireshark on Server and following is
what I see:
One Server: Upon issuing mount command on client:
# tshark -i eth1
Running as user "root" and group "root". This could be dangerous.
