# README for go-nc

## What is this?

This is a simple clone of `netcat` in golang. I wrote it many moons

ago as my first go program. It is slightly different from the

traditional `netcat` in the following ways:

* adds sha256 checksum on network I/O

* traffic stats (number of bytes sent/received)

* hexdump of the traffic

* Bi directional I/O is optional; server always writes to `stdout`

  and client always reads from `stdin`. This makes it easy to

  remember.

## How do I build it?

You will need Go 1.5 or later:

 

    git clone https://github.com/opencoff/go-nc

    cd go-nc

    make

## How do I run it?

`gonc` comes with helpful commandline options. Try:

    ./bin/gonc -h

Or the long-form:

    ./bin/gonc --help

### Simple Example

Lets say that we wish to send a directory's contents to a server whose IP address is a.b.c.d.

On that server create a listening instance of 'gonc':

    ./bin/gonc -c -l :9090 > foo.tar.gz

And on a client try:

    tar cf - . | gzip -9 | ./bin/gonc -c -v a.b.c.d:9090

In the example above, all I/O is checksummed on both sides.
