First, you can programmatically SSH to usern...@firewall.
Then, you can port forward local port 8822 to remote "machine:22".
Then you can programatically SSH to usern...@localhost:8822.

Hi Team,
I am using JSch module and have been successful in using it in most of the conditions. I am using standard way of connecting as provided in some of the examples which is working fine for me. Now I have an additional requirement, SSH is behind the firewall, and following is the manner in which user is connecting to it from his shell:
    ssh firew...@username <mailto:firew...@username>
    password: ********
    ssh mach...@username <mailto:mach...@username>
    password ***************
    su - user
    password: *****

Once user fires this command, he can then fire any commands of interest in this session. I am wondering how to program this using JSch code in my java application. Any help/ideas are welcomed. Regards,
Amol Kulkarni
