iam not geeting the problem of ssh..

Hi,

Check some basic things like, whether you can ssh from your dr server to file server,iptables,and check whether ssh service runs with no problem in you fileserver.

i checked for DR server it can ssh.
actually network firewall blocked ssh.now i can ssh.it solved.
