Re: SSH Shell java exception error

Without more context it is difficult to troubleshoot but I will point out the following from experience and for the record I am running OO 10.51 on Ubuntu 14:

1.) With vmware nodes you will get a java exception error but not always that refers to "no route to host" or "unknown host" when the ip stack is not up on your node

2.) when the system you are connecting to refuses you may get a no route or may get an exception or unknown host

3.) There was an issue with the version and algorithims where when you attempted to connect to Cisco or Ubuntu you would get a similar error to what you have, the solution was to add the following to /etc/ssh/sshd_config, this may have affected other Linux distros.

4.) Also check that your interface on OO is actually up if you have multiple interfaces, I have a OOB and a orchestration management

Hope this helps
