I assume you mean public key based authentication... if so, one "gotcha" that verbose debug messages won't help you with is the permissions on the .ssh directory and the files underneath... they must be owned by the "owner" and cannot have any "other" permissions (e.g. chmod 700 .ssh and chmod 600 on .ssh/authorized_keys )...

Hi, I'd like to use SSH without password so I can use it in scripts (for example in combination with rsync to do backups). I have Carla Schroder's "Linux Cookbook" and I'm trying out the various receipts, but the one for SSH without a password doesn't work. The book is slightly dated, and I wonder if SSH included in CentOS works differently. Any suggestions?
