Yes, there's a distinction. DSA keys are for ssh2, RSA keys are for ssh1. There's some amount of debate as to which is more secure: ssh2 encrypts more of the data, but always uses the same Diffie-Hellman group (which means it's more likely somebody has sat down and cracked it).
In addition, I strongly recommend you investigate ssh-agent, which allows the convenience of only entering your passphrase once combined with the security of an encrypted key. -Brian -- Brian Sniffen [EMAIL PROTECTED] Security Engineer day: (617) 613-2642 cel: (617) 721-0927 Akamai Technologies eve: (781) 874-0699 pi: (314) 159-2654
