openssh unix dev - Jun 2004 - F-Secure SSH / OpenSSH pubkey compatibilty?

I am trying to use F-Secure SSH on a RH7.1 machine to connect using
any pubkey method to an OpenSSH on a Debian 'woody' stable server
(with current Debian security patches).  Interactive password
authentication works.  But I have been unable to get any of the
"passwordless" pubkey methods to work.

I am trying to automate a copy where only ssh is allowed through the
firewalls.  Unfortunately I have to physically travel to a secure room
at another company's site in order to type on the keyboard of the
RH7.1 F-Secure SSH machine.  Therefore I only have my faulty memory of
the failed results.  But it seemed to me that the public key format
was incompatible with the OpenSSH implementation.  Normally I would
copy the id_rsa.pub (called id_rsa_a1024.pub2 or something similar by
F-Secure SSH) to the OpenSSH authorized_keys file.  But that did not
work.

Looking at the contents the pubkey file the format was much different
than what I expected to see and looked more like a PGP style key with
a BEGIN, Version:, Comment: section.  Should I be able to extract the
key somehow in a compatible format?  I read through the F-Secure SSH
man pages that were available on that system but in the time there I
could not deduce how to do that.

Does anyone have any hints?

Thanks
Bob

I think ssh-keygen from OpenSSH can convert the public key to it's
prefered format. Try ssh-keygen -i, and/or see the man page.
