Show ‘n Tell Thursday: SSH tunneling – a must have tool for any travelling consultant (18 May 2006)


With the use of firewalls that also restrict the outbound ports accessible from the corporate networks it is getting harder and harder to access resources at the office while at a customer location. Luckily there is a solution that works most of the time and that all travelling consultants should know about.

SSH tunneling is the solution to so many questions. For some reason many networks allows you to create outbound SSH connections which makes it possible to tunnel Notes (port 1352) and Sametime (port 1533) traffic to a SSH server and from there to the destination. Don’t worry it is much simpler than it sounds.

This tutorial shows you how to set it up. I recommend PuTTY as the SSH client to use. The below screenshot shows an example of tunneling Notes and Sametime traffic to sametime.example.com and notes.example.com respectively.

Tunnelling traffic via the internet beats the hell out of replicating via GSM dial-up or via a fax/PSTN line.
