Passwordless SSH login

I was fiddling with NFS trying to get it to work (previous post) when after a reboot I run into an odd problem: suddenly I couldn't do a passwordless login any more. Took me a while to figure out but there was a very clear error in the syslog: I had changed the permissions in my server home directory to 777 (allow all) to make sure my problems weren't access rights related and the server refused to look at the ssh keys because of this.

A good reason not to work, mind as you never should set the rights like that.

And, btw, the best way to put your ssh key to the server:
ssh-copy-id -i [identity file] [user]@server.
