server 1 which dials into server 2

ssh-keygen -t dsa -b 1024 (no password)


[~/.ssh]# cat >> ./authorized_keys

But when I do ssh I get:'s password:


server1: ssh-keygen -t dsa -b 1024 (no password)
server1: ssh-copy-id -i ~/.ssh/id_dsa
server1: ssh -- get promoted for a password

How do I get the correct user used so I can login with no password?

The permissions on the .ssh directory and/or the files within it are wrong on the remote server.

You can fix these manually yourself, or just use the ssh-copy-id utility to copy your public keys over to the server. This will also fix any broken permissions of this type.

ssh-copy-id -i ~/.ssh/id_dsa

If you still have trouble, you need to look at sshd debug logs on the server.

1 - Where exactly are you adding the public key Could it be you are appending it to /root/.ssh/authorized_keys instead of in /home/user/.ssh/authorized_keys on server2? Make sure you place it in the authorized_keys of the respective user.

2 - permissions (as suggested by Michael)

chmod  700  /home/user/.ssh
chmod 600 /home/user/.ssh/authorized_keys

3 - server1: use the following command to connect.

  ssh -i /home/user/.ssh/id_dsa
