Re: OpenSSH and keys
TeraTerm only supports the SSH-1 protocol. OpenSSH 2 supports both SSH-1 and
SSH-2.
The SSH-2 protocol, however, uses a different algorythm to validate server and
users (DSA instead of RSA). If, for some reason, you only generate DSA keys, or
you configured you OpenSSH to only accept SSH-2 connections, I can see why that
won't work.
As far as I know, ssh-keygen will generate RSA keys by default, and you need a
command line option to make it generate DSA keys, so this may very well not be
the answer you were looking for.
