Accessing ari using x2go

[Yichong Xu]

Hi Predrag,
Thanks for the reply! Sad to hear about the GUI access. Can you tell me how to launch a terminal through X2GO? I didn’t find it in the session types option. Currently my connection cannot launch and it crashes immediately after launching.
Actually my use case is to use jupypter notebook on ari - do you have some advice about how to set this up? I can set up the remote notebook server if I can somehow connect to ari directly through my machine (I guess that is impossible). Thank you very much!

Thanks,
Yichong
