About

TCP port scanner written in go from the book 'Black Hat Go'. Hard coded to scan scanme.nmap.com The implementation uses a worker pool with 100 channels. Returns a list of open ports

Build

make build

binary is in bin

To Do

• allow users to specify number of workers as an option
• allow url to be passed as argument
• ability to parse port strings like 80, 443, 8080 similar to nmap

Enhancements

It's not neccessary to send on the results channel for every port scanned. We can use an additional channel not only to track the workers but also to prevent a race condition by ensuring the completion of all gathered results.
