netcat for Debian
-----------------

A symlink to the netcat binary called 'netcat' has been installed.
However, the canonical name is still 'nc'. If you use netcat on other
systems, it will probably only be installed as 'nc', so keep this in
mind when writing scripts.

Encrypted File Transfer
(courtesy of Tom Buskey <tom@buskey.name>)

Suppose you have an ssh tunnel, and you want to copy a file to the
    remote machine. You could just scp it directly, but that opens up
    another connection. The goal is to re-use the existing connection.
    You can use netcat to do this:

When you SSH in, add -L 31000:127.0.0.1:31000

On the remote:

nc -lvnp 31000 127.0.0.1 > file

On the local:

nc -v -w 2 127.0.0.1 31000 < file

No extra overhead. TCP takes care of error correction. SSH has
    already encrypted the pipe.
