Step 1: Download netcat
I have saved you the trouble of 3 minutes of searching Google and have put nc.exe up on instructables for you to download. Optionally, you can also download nc.bat which is a batch file I have created to automate the process for you. Make sure that if you download nc.bat it is 464 bytes, because I kept on uploading versions and finding out something was wrong with it. If it is not 464 bytes, the program will not correspond with this instructable.
