[jira] [Created] (AIRAVATA-1802) Create SSH connection to resource via JumpHosts.

Raminderjeet Singh created AIRAVATA-1802:
--------------------------------------------

             Summary: Create SSH connection to resource via JumpHosts.
                 Key: AIRAVATA-1802
                 URL: https://issues.apache.org/jira/browse/AIRAVATA-1802
             Project: Airavata
          Issue Type: Bug
          Components: GFac
    Affects Versions: 0.15 
            Reporter: Raminderjeet Singh


If the cluster is only accessible to internal network and GFAC need to create a connection using JumpHost. Workflow is, GFAC need to create a connection with jump host and then to the cluster login node to submit a job. JCraft > Jsch has an example to demonstrate this http://www.jcraft.com/jsch/examples/JumpHosts.java.html

I tried using http://www.jcraft.com/jsch/examples/OpenSSHConfig.java.html to run a ProxyCommand but that did not work as ProxyCommand is not implemented in Jsch. SEE http://www.jcraft.com/jsch/ChangeLog (added support for OpenSSH).
