Hi Srini, Possible reasons:
1. Server is not reachable via network. Try ping the server. *unable to ping (request time out)* 2. openssh server is not running in server. install and start it 3. ssh running in different port other than 22 check the port ssh is running. *no,it is running in port 22 only* 4. Firewall is blocking port 22 check the firewall rules. *no firewall is not blocking. iptables is not running..there is no firewall block.suddenly from today it happens,till yesterday able to logon to that server.* Some problem in physical connectivity i think.
