I have a ssh RSA key in a client OSX 10.9.4. The SSH server is ubuntu. Everything works OK, but the problem is that my OSX ssh-agent seems to be caching the passphrases. The first time I ssh, it is asked. Next time, it is not, and I directly log in the server.
I am worried about security here. If someone steals my machine would have access to the server without entering any password...yeah, I still have my OSX user, but still.
So do you know when OSX ssh-agent asks again?
It seems I have the same question as: http://www.dribin.org/dave/blog/archives/2007/11/28/securing_ssh_agent/
But I don't know how that applies to OSX 10.9.4
Thanks in advance,
