Verify the Login from the local-host to remote-host using the SSH2 key authentication. $ vi ~/.ssh2/local-host_ssh2_key.pubĬomment: '2048-bit RSA, converted from OpenSSH by END SSH2 PUBLIC KEY -Īdd the above public key file name to the authorization file on the remote-host as shown below. Install the public-key on the remote-host that is running SSH2.Ĭreate a new public key file on remote-host and copy paste the converted SSH2 key from the local-host. On local-host that is running openSSH, convert the openSSH public key to SSH2 public key using ssh-keygen as shown below. Convert openSSH public key to SSH2 public key. You can also generate DSA key pair using: ssh-keygen -t dsa command. You should not share the private key with anybody.īy default the ssh-keygen on openSSH generates RSA key pair.
