glad to hear that. Hope my code helped you - at least a bit ....

I remember the biggest pain when making HaaS-libssh work was to correctly
fill/implement the callbacks in the ssh_channel_callbacks_struct,
ssh_server_callbacks_struct
and ssh_callbacks_struct :-(
And the next hard thing was the 'main loop' with libssh events and polling
- lot of 'deadlocks' there .....

On the other hand, I have even prepared patch against libssh to
implement/support some sort of security/welcome banner, but haven't
convince myself yet to send it up.
