The handshake for SSHFS mounting (server -> client) is:
o client sets up a reverse SSH port forwarding tunnel so that you
can login from server to client, even if the client is behind a firewall
o client generates temporary SSH pub/priv key pair
o a script on the server is then issued by the client
o with this script the client places this temp SSH privkey and a known_hosts
file that works for the client-side sshd on the server
o from this script also sshfs mounting (server -> client) is issued
o once the mount has been successfull, all temporary credentials are removed
from the server again (as I said: temporary)
You might want to take a closer look at the ,,x2gomountdirs'' script
in X2Go server and the appropriate locations in x2goclient or
python-x2go. Tell me what language (C++ or Python) you prefer for code
diving and I will point you to the right places in the code.
Greets,
Mike
