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?
Niki

Maybe this CentOS wiki helps?

If you follow the guides step by step they usually work fine. But most gloss over the end permissions/ownership. It is important (won't work without it) that you ensure that the .ssh directory and its contents are owned by the account in which these files reside... to explain it a different way: If the authorized key files are in /home/bob/.ssh, the .ssh directory and its files should be owned by bob. The .ssh directory should have 700 permissions and any files within it 600.

I just gave it a try: works like a charm.
Thanks!

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 )...

One thing that's frequently missed is that the client SSH configuration might require that the server's fingerprint appear in the local known_hosts file. This may mean that you must perform at least one interactive ssh login to confirm the identity of the destination, before scripted ssh will work.

I thought ssh-agent took care of that?
