Trying to get SSH set up in a small cluster - but can't get ssh-add to work. From my reading of the DIY pages (https://www.open-mpi.org/faq/?catego...sh-run-prereqs), ssh-add should add my identity to the ssh-agent so that openmpi processes on my head node can spawn threads on my second node. It doesn't change anything if I give rw-rw-rw- to ~/.ssh/*, so I don't think it's a permissions problem. I am able to ssh between the machines, but it always asks for my passphrase. I've been working at this a while and feel badly because this is just the first step in trying to get openmpi working... :\
Thank you for any help or insight. :)
EDIT: Found this - needed to do "ssh-agent /bin/bash"

...not trying to figure out how to have ssh-agent do it's thing behind-the-scenes... i.e., without having to invoke it and ssh-add every time I run a shell.
Thank you for any help or insight. :)
