Did you put the ssh2 public keywork (id_rsa.pub) into a file
~/.ssh/authorized_keys2 on the other computer? Are both computers using
openssh? If so, maybe one of their configuration files makes ssh1 the
default. To make sure ssh2 is what's used, try logging on with "ssh -2
<username@computer>". To make ssh1 work without a password, make a ssh1
keypair and copy identity.pub to the other computer's
~/.ssh/authorized_keys (not authorized_keys2). Note that although I said
the ssh2 public key goes in the remote computer's ~/.ssh/authorized_keys2,
which works for me, the documentation claims it should be
~/.ssh/authorized_keys. Maybe it would work if you went with the
documentation. In any case, all this can be messed up if the
/etc/ssh/ssh_config or sshd_config files are changed from the default.
For example /etc/ssh/sshd_config could have AuthorizedKeysFile set to
a non-default value. And the default PubkeyAuthentication is "yes";
if it has been set to "no" on the remote computer, the method I
described won't work.
I don't think there's any problem with the two servers using
different passwords for the same user name. So long as you use the
method I described, the password should be irrelevant.
