R: R: Tunneling ssh

[Sauro Cesaretti]

I made other test.
Infact with -L I was able to open the ssh session but later the other
computer couldn't coonect.
After that I have tried with -R and it worked.

Allright, a question for Loïc, if you don't mind.

I know better than to doubt your word, but I can't figure out how that
command works.  As far as I can tell, -L forwards the port from the
computer you are connecting from.  Would not -R *:22:127.0.0.1:2222 be
the only way to open the reverse tunnel as described?
