First off all, great work. And nice idea.

Im having an issue thow, i cant figure out why its not woking on my n900.
I followed the wiki, so i have the 2 scripts on /etc/networking..
and the other 2 scripts on /usr/share.

on the reverse_ssh.sh (at /usr/share/) i added an output to the /home/user/, a text output, for testing only. And it creates the file and fill it (text like "attempt 1.. attempt 2..").
But form some reason it doesn't acomplish the connection.

The odd thing is that if i execute that script "./reverse_ssh.sh" it does conect flawlessly.

So, "if up" does work, it launches the reverse_ssh script.
The reverse_ssh script works (it creates my personal log file).
It wont establish connection (dont know why).
If i execute on shell the reverse_ssh script, it will establish connection.

Any clue what might be happening?

Also, im running power-kernel46, could this be avoiding somehow the execution of the scripts (i think it shouldnt) ?

Thanks in advance guys.

This is really great, thanks! I set up x11vnc to start with if-up and down with if-down, and a respawn after each session from some tutorial somewhere. Is there a way to mimic this concept to allow the ability to VNC from anywhere also? Hope that's not too off topic.

Hmmm, there are ways to tunnel TCP connections over an existing TCP connection, that's what you should be exploring.
I think the term used to describe that is : SSH Tunneling.
