The ssh session is marked as connected after a successful key exchange. 
Currently it is a connection from a client, but we don't know if it is a SSH 
client yet. ssh_handle_key_exchange(session) is needed first to check if we 
talk to a SSH client. But you should setup callbacks before you call 
ssh_handle_key_exchange()

Patches to improve the documentation are welcome! :-)

Did you look at examples/ssh_server.c? This is a simple ssh server 
implementation. We recommend to implement a pre-forking server for security 
reasons.


Best regards
