How to enable ssh-agent?

[CaseyLabs]

I'm trying to setup Cmder to use ssh-agent forwarding:

λ ssh-agent
SSH_AUTH_SOCK=/tmp/ssh-JqBCMa6092/agent.6092; export SSH_AUTH_SOCK;
SSH_AGENT_PID=7840; export SSH_AGENT_PID;
echo Agent pid 7840;

λ ssh-add my-public-key.pub
Could not open a connection to your authentication agent

Any ideas what I'm doing wrong here?

Thank!

same problem here, if someone is using this without problems i would appreciate a hint on how to set it up.

I came up with this gist, which does the trick: https://gist.github.com/bojanrajkovic/6997145eda613467ace4. You can add this to init.bat. I'd love some input from @Bliker or someone else as to how to get this to run on "startup" without being overwritten by Cmder upgrades.

Sweeet! Works as advetised :-)

I would even go as far as making this an official option (perhaps not default, but an option nonetheless!)

I wrote another solution for the problem which doesn't run ssh-agent for each new Cmder instance.

It works without temporary files, only runs ssh-agent when it isn't running and adds ssh keys in %HOME%.ssh*_rsa if they were not yet added.

Nice, that's much better than my hack. I've switched to Powershell + posh-git in the meantime (which has built-in support for ssh-agent), but this is a cool solution.

Using the script from @bojanrajkovic it works for me. With @Shoozza's fix I only get: "Could not open a connection to your authentication agent". Strange, I don't see why the call to ssh-add shouldn't work in the second script as well.

I get the same with @Shoozza 's fix also: Could not open a connection to your authentication agent. Would be nice to resolve as it's a cleaner workaround for this issue.

[Shoozza]

Rewrote the script to handle the issue (revision 7).
The problem was that another ssh-agent was running already and didn't use the /tmp/ssh-agent.sock.

Thanks, @Shoozza. It's working fine for me now 👍

@ogrim Same for me - thanks @Shoozza! Is there a way to automatically run this each time a new Cmder window/tab is opened?

[ogrim]

You can add it to cmder/vendor/init.bat. I have the script on my path as agent.cmd, so I have only added call agent as the last line in init.bat

[Shoozza]

I added @call "%CMDER_ROOT%/vendor/agent.cmd" at the end of cmder/vendor/init.bat.

@ogrim @Shoozza Thanks, exactly what I was looking for! This has been a huge headache for me with Cmder for a long time - you should definitely submit a PR 👍

@Shoozza Cheers, this is fantastic.

This need to be added to the repo !
