- 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.

- Examples
- --------
-
- Many examples can be found in /usr/share/doc/netcat/README.gz. The rest of
- this file collects some more that have been contributed by users.

-
- 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.
