Re: Initiate SSH session from other side?

dspfun a écrit :
Is it possible to somehow trigger an SSH session from inside a network,
so that I can use an SSH session from outside the network into the
network? For example by having a program (crontab) or something
initiating the SSH session from inside the network to a specific
IP-address and port number? The problem is that it is not possible to
directly ssh into the network from outside the network.

BR!


I did that from my winXP client at work to my linux openssh server at home. If I want to use VNC to work on my work desktop, I send a mail containing some keywords. Then I created a rule in Outlook that run if the mail contains these keywords. This rule start a script that open an ssh connection to my home system automatically thanks to keys authentication and ssh agent.
This is not very secure because the keywords are send in plain text, however someone stealing these keywords could only start an ssh tunnel between my work computer and my home computer.
