Re: ssh2 passwordless login does not work with ssh-keygen -t rsa?
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.
