This is with regards to http://www.open-mpi.org/faq/?category=rsh#ssh-keys
It says to check if you have an ssh-agent running. How are you supposed to do that? I've tried "ps -u myusername | grep ssh-agent", but didn't know if that's the proper thing to do.
Also, it appears that I do *NOT* have an ssh-agent running automatically for me. How often do I have to start one up? It appears that if I start one up and log out and then log back in again, the old ssh-agent is still there but not usable. I have to start up a new one. So, do I have to start an ssh-agent each time I log in?
Or, I could use no DSA passphrase, but that seems to be frowned upon.
