GO simple port scanner

Introduction

A simple implementation of a port scanner, comparing the speed between a linear scan and with the usage of goroutines. To test it, just replace the nGoroutines variables with the desired value.

Note: Be careful with the max number of goroutines and the target you test. You can generate some issues.

Execute

Simple usage:

go run portscan.go

For execution only with goroutines, just pass a value (ex: 1):

go run portscan.go 1

TODO

• Receive parameters as input (host, number of goroutines)
• Receive port range as input (ex: 1-1000)
• Store results into a file
• Sort results by port
