Git auth on EC2 works via command line within X2GO, but not by SSH

Question

I work on multiple EC2 instances which each contain repos that need frequent updating. So I ssh to the EC2 instance, cd to the repo, and run git pull. Simple enough.

The problem is outlined in the diagram below. The git pull only works when I

• from my laptop, log remotely into my workstation via X2G0
• open a terminal window in the GUI
• ssh into the EC2 from within the workstation

It does not work when I:

• ssh directly to the EC2 from my laptop, even though I authenticate with the same key

It even does not work when I

• from my laptop, ssh into my workstation
• ssh into the EC2 from within the workstation

It is the last one that is a particular puzzler and has cost me some productive time when X2GO is not feasible. What settings could be different about opening a terminal window within the Ubuntu GUI, and then using ssh there, that are not present when I ssh to the same computer and am therefore on the command line already? All the same environment variables are present.

Answer 1

Have you already have a look as possible ssh agent forwarding that the x2go client might use silently?

(sorry, cannot comment at that time)
