port-scanner

Port Scanner

This is a simple terminal application that allows you to find opened ports on your network.
Inspired by nmap

Setup

First, you need to download Go
Then clone this repository:

git clone https://github.com/0l1v3rr/port-scanner.git
cd port-scanner

On Linux or Mac, use the make run command, to run the app.
On Windows: go run cmd\port-scanner\main.go

Flags

--protocol -> tcp/udp - default is tcp.
Example usage: go run cmd\port-scanner\main.go --protocol udp

--ip -> The IP address you want to scan. Default is your device's IP.
Example usage: go run cmd\port-scanner\main.go --ip 192.168.0.1

--port -> The only port you want to scan. By default, the app will scan the most known ports.
Example usage: go run cmd\port-scanner\main.go --port 443

--closed -> With this flag, the app won't show the closed ports.
Example usage: go run cmd\port-scanner\main.go --closed

--all -> With this flag, the app will scan all the ports from 1 to 65535.
Example usage: go run cmd\port-scanner\main.go --all

--dialtime -> The dial timeout you want to use.
Example usage: go run cmd\port-scanner\main.go --dialtime 10

--domain -> The domain name you want to scan. Overrides the --ip flag.
Example usage: go run cmd\port-scanner\main.go --domain google.com

You can combine the flags.

For example: go run cmd\port-scanner\main.go --ip 192.168.0.1 --port 23
The line above means that you are scanning port 23 of IP 192.168.0.1.

Use anywhere as a command

For example on Linux, open a terminal and type this command:

nano ~/.profile

Now scroll to the bottom and paste this:

export PATH="$PATH:/usr/local/port-scanner/bin"

This is just an example, you should use your own path.
