SSH-Agent can't open a connection to authentication agent?

  • 772

When I SSH into my firewall server, then attempt to ssh into another machine on the local network from there I get the following error:

Could not open a connection to your authentication agent.

Is there a way that I can have the agent run correctly from within another SSH session?

ssh ssh-agent

  1. Yes. you can enable agent-forwarding by adding

    ForwardAgent Yes

    in your ssh configuration file (either ~/.ssh/config for user or /etc/ssh/ssh_config system wide.

    See also http://drupal.txwikinger.me.uk/content/configurations-ssh-make-some-things-more-convenient.

    Alternatively, if ssh is called with the option -A, the agent forwarding is also enabled as pointed out in the other answer.

    I addition to what txwikinger said, you can also just use the -A command line option when SSHing to your firewall.
