How do I turn the SSH Agent off? I'm having troubles with Vagrant and it indicates that I should disable my SSH Agent before continuing, yet I can't find a straight forward answer. How would I do it?

Temporary answers work too. I'm happy with how my environment is setup, it's just this particular situation where I need to verify that disabling the SSH Agent corrects the issue, even if I then turn it back on.

unset the environment variable $SSH_AUTH_SOCK. In bash, from where you run the vagrant commands, simply:

export SSH_AUTH_SOCK=""

  • Any idea on how to do this permanently?

  • The other answer sounds like permanent solution. Or you can write this into your ~/.bashrc. It will practically disable it permanently for all the sessions. (after relogin).

    Works great for me. To disable it for just a single connection (while preserving the agent in the terminal session), I ran a command like this: SSH_AUTH_SOCK="" ssh [email protected]

eval $(ssh-agent -k) kills the agent in the current terminal.

It runs these commands

unset SSH_AUTH_SOCK;
unset SSH_AGENT_PID;
echo Agent pid 89141 killed;
