RustScan
The Modern Port Scanner
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. -

Smap
a drop-in replacement for Nmap powered by shodan.io
Smap is a passive port scanner designed as a drop-in alternative to Nmap while using Shodan.io data. It accepts many familiar Nmap-style command-line arguments and can produce Nmap-like output formats, which makes it easier to integrate into existing workflows. Because it relies on Shodan’s free API, it can scan quickly without directly contacting targets in its default mode. The project emphasizes speed, with support for scanning large numbers of hosts per second. Smap can provide service and version fingerprinting, vulnerability detection, and results in formats such as XML, greppable, normal, JSON, and custom output. It is useful for authorized reconnaissance where fast external visibility matters, while users should remember that passive results may be delayed or incomplete compared with active scanning. -

scanless
Online port scan scraper
scanless is a Python command-line utility and library for running port scans through third-party online scanning services. It is built for users who want quick visibility into exposed ports without running a local scanner directly from their own machine. The tool can scan an IP address or domain, choose a specific supported scanner, select a random scanner, or run all available scanners. It supports services such as ipfingerprints, spiderip, standingtech, viewdns, and yougetsignal. scanless can return raw scan output as well as parsed results that include port, state, service, and protocol details. The repository is archived and no longer maintained, so it is best treated as a legacy utility for authorized testing, research, or reference use. -

TraceMAC - Traceroute for MAC addresses
TraceMAC is a command-line Layer 2 traceroute for Cisco switches
TraceMAC is a Windows/Linux command-line tool that allows you to trace a specific MAC address thru Cisco switches. It works by connecting to a switch using SSH, SNMP, Telnet, HTTP or HTTPS and do some "show commands" and later process the output, this will happen recursively until it finds the switch where that MAC address (PC/Printer/Etc) is directly connected. Note: It works with Cisco switches only and you must have CDP enabled at least on trunks/links between switches! Is tested with Cisco switches: Catalyst: 2960,3560,3750,4948,6509,9200,9300,9500 (All protocols) Nexus: C9332C, 93180YC-EX (NX-OS SSH) Express 500 (HTTP) FYI: It uses Nbtscan.exe (NetBIOS) as a alternative method to discover the mac address of a host and now seems that it is considered a malware. Anyway it is just a simple network tool that can scan the network similar to NMAP or Angry IP Scanner, etc... -
