No route to host
In linux,
[root@ccixapp-nprd1-213 ~]# ssh ccixapp-nprd1-211
ssh: connect to host ccixapp-nprd1-211 port 22: No route to host
I have checked the sshd it running ,22 port is open. I am able to ping the server. Still i am unable to do an ssh.
Any suggestions/ help?
Thanks
Ravi

Re: No route to host
Exactly which server are you able to ping and _from where_?
Are these two hosts in the same network segment? If not, have you forgotten to define a gateway?
Can you post the network configuration settings of both ccixapp-nprd1-213 and -211? The outputs of "ifconfig" and "route -n" commands would be very useful in solving this problem.
Is there a network firewall somewhere? Or is your server configured with an iptables filter?
A firewall or an iptables filter can certainly be configured to send a false "no route to host" response to some non-approved connection attempts. A more common strategy would be to make the firewall/filter just eat the non-approved packets and not send anything back.

Re: No route to host
If you can ping to this system there is no problem in routing.
This seems like pure firewall issues.
check if any reply from remote system port 22
when you telnet.
dont forget to check your selinux policies also.
Good Luck...!

Re: No route to host
Try to do traceroute to ccixapp-nprd1-211 and print us the result
Maybe there is firewall blocking in between or server routing server might need to include the end server ip range.
Good luck!
