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.
Thanks,
HariPrasadh
