Joseph,
I've had the similar problem as You. I upgraded fromm ssh1 to ssh2 and persistent
Portforwarding was no longer possible.
I,ve posted a question to comp.security.ssh but receved no answer or hint until now. I
think, it's a bug in ssh2 (if You are looking into the source-code, you will find a
comment in the "accept socket connection request"-callback function, that there is a
serious problem concerning persistent portforwarding.
As a quick hack workaround, I've written a short C-program which compiles using gcc on
a Sun Solaris 2.6.
The program works as a proxy to ssh2.
E.g. the original ssh2-forwarding command was:
Host1%> ssh2 -f -L Port1:Host2:Port2 Host2
Then You need a 2nd unused Port on Host1, e.g. Port1a. You must start the proxy as
follows:
Host1%> nohup multissh2 -l Port1 -s Port1a -h Host2 >logfile 2>&1 &
It works when You are using public key authentication from Host1 to Host2.
Each time You connect to Port1 on Host1 a new ssh2 is forked listening on Port1a on
Host1. Now the proxy copies everything it receices on Port1 to Port1a and vice versa.
It works really fine, but it's a hack.
Regards,
Stefan

Betreff: persistent forwarding
Hello,
I've been able to set up 'one-time' forwards - where the ssh connection
terminates when the forwarded connection terminates - but I would also
like to set up persistent forwards - where the ssh connection is available
for multiple forwarded connections, perhaps even many at one time.
Is it possible to do this with ssh? Here's my environment:
SSH Version 2.0.13
FreeBSD boxen
Thanks for any help you can give me.
