I've set up my admin user to log in using the public/private key method, but for some reason, when I do the same with my root user, it doesn't work. Anybody know why?

In sshd_config, relevant code:

Code:
RSAAuthentication yes
PubkeyAuthentication yes
# AuthorizedKeysFile   %h/.ssh/authorized_keys
PermitRootLogin yes
AllowUsers pshields root



Then I saved the public key in /root/.ssh/authorized_keys

However, though my admin login works, the root login denies my key. Any ideas why?

1. Uncomment the AuthorizedKeyFile line.
Code:
AuthorizedKeysFile   %h/.ssh/authorized_keys


2. Restart SSH.
Code:
/etc/init.d/ssh restart


See if this works.....

Also, check the permissions on the .ssh directory and the authorized_keys file. If they aren't correct, ssh will reject the key.

For security purposes, you should either use sudo, or su - to go to root, but only after you've logged it from a limited user account.
