How to do ssh connection from client-to-remote machine1-to-remote machine2-to-remote machine3 and execute command on remote machine3

[Sasikanth Eda]

Hi All,

I am working on an automation scenario, where the steps mentioned below are
to be performed;

1. Script has to run on client machine.

2. Using the Perl script on client machine, we need to login to remote
machine-1 using ssh protocol.

3. From remote machine-1, the script should login to other remote machine-2
using ssh protocol.

4. From remote machine-2, the script should login to other remote machine-3
using ssh protocol and execute a command, collect the output.

Here limitations is we cannot directly contact remote machine-3 from client
and our script should not create any copies of code on any of the remote
machine used in the scenario.

I am a Perl beginner and explored Net::OpenSSH module, but came to know
that, using this we can connect only to client -to- remote machine-1.

Any thoughts/example code to handle this scenario.


Thanking you,
