Dear Sir/Madame,
I have Machine A (my linux machine), Machine B (jumpstation through which we access internal network machines, accessed via ssh) and Machine C (internal network machine which is accessed via ssh as well).
I want to run PERL Net::Expect::SSH module based script which will access machine C from machine A by going through machine B because only machine B can access the internal network. How can I access machine C from machine A without having to do an ssh login into machine B manually. I just want the script to run on machine A and get access to machine C transparently. Can I use ssh tunnel; if yes, then how to do this. Please explain.
All the 3 machines are Linux machines running ssh.
Thanks in advance for your help.

Hi,

I'd do this with port forwarding using iptables. just pick a TCP port, say 2222, and have B redirect ssh inbound requests on that port (ostensibly from A) to port 22 of C.

Hi,
Im also looking after the same scenerio here is my post .But you can achive the server using port forwarding
