Connect via ssh to a remote machine from an intermediate (jump host) machine

[kishankarun]

The current SSH Library supports connecting to a remote machine and execute commands.

In a case where there is a "jump" server which only has a connection to my actual targeted machine (Device Under Test [DUT]),

Development Machine (Laptop) ---> Jump Server (jumpserver.com) ---> DUT (dut.com)

This could be approached now in 2 tedious ways:

1. Open Connection | jumpserver.com
   1.1. Write [email protected]
   1.2. Wait for password prompt and address it (check for prompt, provide password etc)
   1.3. Keep using the combination of Write and Read for the commands to be executed (Write whoami, $result=Read 2s)

2. Create a tunnel through jump server to the DUT and keep it running in the background (which will simulate a direct connection)
   2.1. Connect to the tunnel and proceed to work as if the Laptop is connected directly to DUT

• The first approach is too tedious as we don't get to leverage all the keywords provided by SSHLibrary, as it is dependent only on Write and Read
• The second approach has a dependency on the created tunnel, and if the tunnel is broken, the tests start failing (especially challenging when run with automation tools like Jenkins)

Would it be possible to provide a 2 level Open Connection
or a support for "nested" Open Connection, just in case there are more than one jump servers

Is there any alternate way to approach this situation?
