Dropbear for Debian
-------------------

This package will attempt to setup the Dropbear ssh server to listen on
port 22.  If the OpenSSH server package ("openssh-server") is installed,
the file /etc/default/dropbear will be set up so that the server does
not start by default.

You can run Dropbear concurrently with OpenSSH 'sshd' by modifying
/etc/default/dropbear so that "NO_START" is set to "0", and changing the
port number that Dropbear runs on.  Follow the instructions in the file.

This package suggests you install the "openssh-client" package, which
provides the "ssh" client program, as well as the "/usr/bin/scp" binary
you will need to be able to retrieve files via SCP from a server running
Dropbear.


Replacing OpenSSH "sshd" with Dropbear
--------------------------------------

You will still want to have the "openssh-client" package installed, as
it provides the "ssh" and "scp" binaries. When you install this package,
it checks for existing OpenSSH host keys and if found, converts them to
the Dropbear format.

If this appears to have worked, you should be able to change over by
following these steps:

1. Stop the OpenSSH server
   % /etc/init.d/ssh stop
2. Prevent the OpenSSH server from starting in the future
   % touch /etc/ssh/sshd_not_to_be_run
3. Modify the Dropbear defaults file, set NO_START to 0 and 
   ensure DROPBEAR_PORT is set to 22.
   % editor /etc/default/dropbear
4. Restart the Dropbear server.
   % /etc/init.d/dropbear restart
