Re: SSH Public key authentication

Hi,

Say u r trying to ssh from server1 to server2.

The hostkey key pair of the server1 should be copied to the server2.

Check /etc/ssh2 directory for ssh_config and sshd2_config files and check that server1 is present in knownhosts directory.

Also the user based authenticationkeys needs to be copied... in /home/root/roor/.ssh2 directory. Check for that also.

Re: SSH Public key authentication

You must copy your id_dsa.put to remote .ssh/authorized_keys file.

The permissions for the .ssh directory should be 700 and for the authorized_keys file 600. StrictMode checks the files permissions.

Hi,
I don't know, where is the problem. So better try again from scratch.

Also find the necessary docs for it.
