Add re-exec for server This allows ASLR to re-randomize the address space for every connection, preventing some vulnerabilities from being exploitable by repeated probing. Overhead (memory and time) is yet to be confirmed. At present this is only enabled on Linux. Other BSD platforms with fexecve() would probably also work though have not been tested.

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.
