Re: Have socks proxy working with libssh

[Alberto Garcia <agarciaillera@xxxxxxxxx>]

Hi,

It's me again,

I've been trying for days to make this work, I've read OpenSSH code to see
how are they handling it... but still I don't know how to implement this
with libssh. I'm not asking to get the code to make it work but a guideness
on how SOCKS5 works with libssh and some hints about which APIs should I
used.

I've found this old stackoverflow post (
https://stackoverflow.com/questions/19654941/dynamic-port-forwarding-libssh-c)
in where someone is trying to do the same thing but the respones doesn't
have any indications about how to implement it using libssh.

Can you please help me with this?
