Hi,
I'm working with one of the sample programs, direct_tcpip.c, which uses the
libssh2_channel_direct_tcpip_ex to connect to a remote server via SSH.
That much is working great. I can talk to the server, everything is good.
However, I would like the remote server (which may or may not be receiving
a connection from SSH; it may also receive a connection directly over
TCP/IP without SSH) to:
1. Determine if the connection is coming in via SSH, and
2. If coming in via SSH, determine the username and type of
authentication that was used (password, key, etc). Or, if I can't determine
the type of authentication, at least determine the username that was used
to authenticate.
It's not clear to me if this is even possible:
- The server may not be on the local host (I may connect from host A to
server B, which connects via TCP/IP to server C, although that leg would
not be encrypted),
- For the life of me, I can't figure out a way to take the TCP/IP socket
from accept() (that's all I've got on the server at the time) and turn that
into something useful (like a LIBSSH2_SESSION * or something). And even if
I had a valid session, I can't find an API that would return the username
that was used to authenticate a session.
Is this sort of integration possible with libssh2?
Thanks in advance for any help!
/Jeff
