[X2Go-User] OS X and proxy server option - can't connect

[Madog]

Hi All:

I am using the proxy server option on x2go, and have gotten it to work on Windows and Debian, but not OS X and hope to get some help.

In my tests: 
- I use the same server, same ssh keys etc. and connect from Windows and Linux (Squeeze)
- from a command prompt on OS X, I can connect by issuing:  ssh -X -A -t externaluser at externalIP ssh -A -X internaluser at internalIP
- bash is the default shell on my Mac
- however, when we try to connect via the x2go GUI, it gets stuck saying "Connecting" and goes no further until I close the session (for what it's worth, it's not a "forced quit" so I don't think the session has crashed, just won't connect).

FYI - on linux, on the "client", I issue the following before trying to connect the first time on both keys and have tried this on OS X as well with "no joy":
NewUserVar=newuser
PathVar=/home/newuser/.ssh/newuserfolder
chmod go-w /home/$NewUserVar
chmod 700 /home/$NewUserVar/.ssh
chmod 600 $PathVar/id_rsa
ssh-add $PathVar/id_rsa

Any suggestions?  Has anyone else had this issue, figured it out?  Thanks!
