==== ozymanDNS and SSH over DNS====

  -. Download [[https://dankaminsky.com/2004/07/29/51/|Dan Kaminsky]]'s OzymanDNS from http://www.doxpara.com/ozymandns_src_0.1.tgz
  -. Add an NS record for a subdomain you want to use for the OzymanDNS server (eg.  ozyman.example.com), using the CNAME of  the host running the OzymanDNS server (eg  host78.example.com).
  -. On the server, start: <code>sudo ./nomde.pl -i 127.0.0.1 ozyman.example.com</code>
  -. On the client, run: <code>ssh -C -o ProxyCommand="./droute.pl -v sshdns.ozyman.example.com" localhost</code>
   - Congratulations, you should now have an SSH connection open to the host that's running OzymanDNS.
