[ILUG] [Beginner] SSH Tunneling

[Kevin Harry]

Hello group,

I'm new to this group and linux. I'm seeking help to setup SSH tunnel to my university's server. The server setup is described below:

LOCAL: My local laptop at home - Window7 laptop with Cygwin installed. I have working bash shell.
FENOM: This is the intranet server of my university which is accessible from any outside network/internet machine (e.g LOCAL). 
XEON: This is the main server or cluster where hadoop is installed. One can login to this server only via FENOM.

Henceforth, using above names instead of IP address.

Requirement:
The Hadoop cluster interface is available at http://localhost:50130/jobtracker.jsp on XEON. I want this interface accessible on my LOCAL laptop with same URL.

Solution:
Create SSH tunnel to LOCAL->FENOM-> XEON.

Steps taken so far:
1. created password less login from LOCAL to FENOM and FENOM to XEON. But I can't ssh directly to XEON from LOCAL with this. (this is correct I guess, unless tunnel is setup)
2. On LOCAL: executed ssh -L 2222:xeon:22 kevin at fenom  [Successful]

Problem:
Now I think I have to execute this command on my LOCAL laptop:
ssh -L 50130:localhost:50130 kevin at fenom [Failed]

To be able to access hadoop interface (http://localhost:50130/jobtracker.jsp) on my LOCAL laptop. But this is not working.

Please help me on how to fix this. I think I am doing something wrong, kindly point out my mistake to setup the SSH tunnel successfully.

Thank you very much.

Regards,
Kevin
