Hi (especially Mike :) ),
we're currently evaluating x2go on debian squeeze (server) / ubuntu natty (client). Basic functionality works, but some of our users will need access via an intermediate ssh hop. Now if the x2go clients (I tested x2goclient and pyhoca-gui) would honour ~/.ssh/config, I could simply roll out a ProxyCommand line, but so I have to resolve to setting up the relevant tunnels manually. pyhoca claims to have some support for intermediate hops, but I was not able to use it in any understandable way. What's the recommended way to achieve this feature?
Also, pyhoca-gui was not able to accept my rsa private key and claims it's a invalid dsa key (which is correct but not helpful ;) ).
If any of this is wrongly adressed here, please point me to the correct place.
Yours Karsten

x2goclient uses libssh for setting up the ssh connection. PyHoca-GUI
uses Python Paramiko for handling everything SSH'ish. Paramiko is not
able (without explicit coding) to handle SSH config files.
PyHoca-GUI can handle SSH proxying (forwarding tunnels) for SSH
connections. Please take a look at the profile manager in PyHoca-GUI
and esp a closer look at the connection settings. If this stays a
riddle, I can send you an example session profile config privately.
Also, pyhoca-gui was not able to accept my rsa private key and claims it's a invalid dsa key (which is correct but not helpful ;) ).
This might just be a misleading error message. I always use RSA keys
with PyHOca-GUI and they work fine. The error message you encountered
could mean that the SSH priv key used with PyHoca-GUI is not in the
server-side authorized_keys file. The error message should honour this
experience and I should maybe rewrite it (it's a Paramiko message that
I catch up and push to libnotify->the-screen).
Greets, Mike
