Hi Thanks for your prompt reply, Can you elaborate in details

As I can seem I am able to ssh the remote node 10.128.1.35

Code:
root@rinams01:/# ssh -b 10.128.5.7 nsuser@10.128.1.35
Warning: Permanently added '10.128.1.35' (RSA) to the list of known hosts.

AND Snoop enabled at rinams01 gives me following thing... does it make any sense.
note: masterservice is 10.128.5.7 configure on oce0:5 a virtual IP on VCS cluster server.
