On this note, I know this has been rehashed many times before, but
using OpenSSH 3.8 on SUSE 9.1, I couldn't get host authentication to
work. I followed all the instructions out in the web but everything
failed. I ended up copying the root's dsa key to every user's ssh
directory and using public-key authentication. Has someone successfully
implemented host authentication using SSH (hopefully v2) and has
written it up in a nice How To?
