Open Source Linux Port Scanners

Masscan is an Internet-scale port scanner, able to scan the entire Internet in just 6 minutes or less. It's considered the fastest port scanner and is similar to the famous port scanner nmap, and like port scanners scanrand and unicornscan it uses asynchronous transmissions. However, it is more flexible when it comes to arbitrary port and address ranges. Masscan not only detects when ports are open, it can also check banners. And while it is useful for smaller, internal networks, it's designed with the entire internet in mind. Do take note however that Masscan uses its own custom TCP/IP stack, so anything other than a simple port scan could cause conflict with the local TCP/IP stack unless certain configurations are done.

The Modern Port Scanner. Find ports quickly (3 seconds at its fastest). Run scripts through our scripting engine (Python, Lua, Shell supported). Scans all 65k ports in 3 seconds. Full scripting engine support. Automatically pipe results into Nmap, or use our scripts (or write your own) to do whatever you want. Adaptive learning. RustScan improves the more you use it. No bloated machine learning here, just basic maths. The usuals you would expect. IPv6, CIDR, file input and more. Automatically pipes ports into Nmap. RustScan is a modern take on the port scanner. Sleek & fast. All while providing extensive extendability to you. Not to mention RustScan uses Adaptive Learning to improve itself over time, making it the best port scanner for you. Speed is guaranteed via RustScan. However, if you want to run a slow scan due to stealth that is possible too. We have tests that check to see if RustScan is significantly slower than the previous version.

jNetMap is a graphical network monitoring and documentation tool. It will ping all registered devices every x minutes, updating the status according to the result of the ping. Requires Java 8 or higher

NimScan is a fast and simple port scanner written in Nim, designed to identify open ports on a network efficiently.

This project is used to establish a TCP/UDP port mapping from an ISP NAT public address to a local private address. If all layers of NAT are full cones (NAT-1), any host can access internal services through the mapped public address. In bind mode, all traffic does not go through this program.

Unicornscan is an asynchronous TCP and UDP port scanner developed by the late Jack C. Louis.
