Doesn’t work for me. It gives me “Agent admitted failure to sign using the key.” message when I try to log in without password.

Neat. This was easy to set up on one of my computers. On the other one, it was a bit more stubborn. For the benefit of someone else who’s bit by it, sshd will not accept an authorized_keys file if either directory ~/.ssh or ~ are writable by Group or Others. The difficult system was PCBSD, in which every user also has their own group and their directory is writable to that group.

You won’t be able to add your public key on a server where you don’t have a valid login/password combination.

And just to add my own geek stuff :
To get a password-less connection from local user1 to remote user2, copy the user1 public key(id_rsa.pub) to the remote user2 “authorized_keys” file using a pipe over ssh:

$ cat /home/user1/.ssh/id_rsa.pub |ssh root@remote_server ‘cat >> /home/user2/.ssh/authorized_keys’

This would do the same job as ssh-copy-id without the 2 out of 3 “weak” points revealed by rameesh.

I’m a bit confused. It seems you can add your public key to the remote host and grant yourself access. This seems like no security at all. What am I missing?
