The current putty seems to be able to generate rsa1, rsa or dsa keys. As
far as I can tell with ssh2 you need to generate a dsa key, then use the
OpenSSH3 ssh-keygen to turn it into a key you can use with ssh2.

There's an option to generate ssh2 keys, transfer your dsa public key to
the Linux machine and do it there. Due to security problems, I suggest
either dropping ssh1 protocol or going to OpenSHH3.0.2p1 or later.

Hope this gets you going.

  Programming without software engineering is like sculpting with a chain
saw. The very talented can produce a work of art, the mediocre wind up with
a misshapen lump in a pile of rubble, and in neither case does the end
result have more than a passing resemblance to the original intent.
