Port Scanning 📟
The best option to identify Ports, Protocols, and Services (PPS) on a target would be to scan all ports (65535) of the remote system.
TCP Scanning
Nmap
Simply Scan
Complex Scan
Masscan
Masscan is the fastest port scanner, it can scan the whole internet in 6 minutes.
Bash Port Scanner
This one is created by @s4vitar:
Another bash port scanner, but this time more simply.
UDP Scanning
Pentesters often forgot to scan for open UDP ports, although UDP scanning can be unrealiable, there are plenty of attack vectors lurking behind open UDP ports.
Hint: You can launch a syn scan and udp scan at same time:
sudo nmap -sS -sU IP
