Afternoon cluster party goers,
I'm having trouble on a cluster with passwordless ssh. I followed all the
steps (I think). On the head node, I generated the public and private
keys and then copied id_rsa.pub to authorized keys. Then I tried
logging into compute nodes and it asks for my password every time
(regardless of the number of times I log into the node). I've tried changing
the permissions on authorized_keys a few times (600, 644) and that
doesn't seem to change the behavior. Any ideas?
a) Check PAM -- could be screwed up, but unlikely
b) Kill selinux by shooting it in the head a few times and then
clubbing the corpse until it stops twitching -- quite likely
c) Always possible that there is some sort of wierdness elsewhere in
your firewall setup or some inherited file or in the permissions
associated with known hosts or... but you know that and I expect you've
checked it all.
I vote for selinux, but wouldn't be surprised if it were pam.

Thanks!
Jeff
