PATCH : Adding SSH Agent forwarding basic support

[Caeies]

Hi all,

Please, find enclosed a proposed patch for supporting SSH Agent forwarding. From my git log :

    Adding basic support for SSH Forwarding agent.

       * Client is able to ask and forward ssh agent.
       * Server is able to use and ask a forwading agent.
       * Server create a dummy local agent for use by other client from this
         side. NOTE : this one is still buggy, we need to be able to answer
         to more than one client !!!

I'm not happy with the way the agent.py was modified ... If people have suggestions, I'm open to them !

Hope this will be usefull.

for what it's worth, voting +1 on this one - it would be very useful to have this ability in fabric (which is based on Paramiko).

+1 for paramiko agent forwarding support

Great! This patch would get rid of needing to use this work-around:

I have updated the patch (but the code is the same as the previous one) for helping people applying it. Looks like the first one was not well formed.

Hope this helps.

I'm still open to better solutions :).

./test.py succeed with this test.

Regards

Caeies.

Hey Caeies,

That's a great new year present! :)

Maybe you could just fork paramiko on github and apply your patch?
I did this with your initial patch, but I was only interested in client, so my fork is not complete.

It would also be great if you could provide some basic usage examples, because couldn't make use of your patch without changing paramiko sources.

But anyway, thanks a lot!

Caeies, I just pull requested your new patch to robey, I'm really looking forward to see it integrated since I need it for pyfabric :)

OK

I've applied the patch as found on GitHub, but it does not work for me. Also, because of the lack of documentation, it's not clear to me how it should work.

Is there anything I need to do to make Fabric actually use the agent forwarding?

Agent forwarding "manually" with "ssh -A" works fine for me, but that doesn't work in Fabric.
