How to run automated rsync using ssh2

i am trying to setup rsync between two machines over ssh2 protocol. Earlier we used ssh1 for automated rsync without any passphrase, but recently we migrated to ssh2 and running rsync with ssh2 prompts for passphrase.

I generated a new SSH2-RSA key and that too without passphrase, but it still asks me for the passphrase.Her开发者_运维百科e is the command that i run for ssh /usr/bin/ssh -2 -i /usr/local/www-rsync-key fsuser@xyz

What steps do you have to do to get an ssh2 key with a null password to work? I'm guessing there are certain settings in /etc/ssh/sshd_config you have to set, but I can't figure out what!

This question appeared on Superuser, discussing the topic of ssh without a password.

If you're getting prompted for a password, check that you've added the public key to the correct file on the far side (could be authorized_keys2 now), and that the directory permissions are correct (.ssh and its contents shouldn't have any group or world permissions set).
