I had installed UEC 10.04.
It is a 2 server configuration with CC, CLC, SC and Walrus on one server and NC on another server. I could run instance of images, But when i try to ssh to the instance, it doesn't work.
It shows ssh: connect to host xxx.xxx.xxx.xxx port 22: No route to host.
This to me seems there is a problem with my network connection.
Kindly let me know if you find anything problematic please.
Pl find below the ifconfig -a output of the two servers:
