Re: Problems with protocol 1 from OpenSSH

["Max Bowsher" <maxb at ukf dot net>]

I'm not an SSH expert, but it looks like you are trying to use a protocol 2 RSA
key for protocol 1.

You should use ssh-keygen -t rsa1 to get a key suitable for protocol 1.

Even better, use the ssh-host-config script, which will set up OpenSSH for you.

See also ssh-user-config for easy generation of user keys
