How to Scan IP address and find all open ports

Scanning IP address for all open ports Scan port 80 on the target system nmap –p 80 Scan ports 1 through 200 on the target system nmap –p 1-200 Scan (Fast) the most common ports nmap –F To scan all ports (1 – 65535) nmap –p– To scan using TCP connect (it takes longer, but is more likely to connect): nmap –sT To perform the default SYN scan (it tests by performing only half of the TCP handshake): nmap –sS To instruct Nmap to scan UDP ports instead of TCP ports (the –p switch specifies ports 80, 130, and 255 in this example): nmap –sU –p 80,130,255 Run a fast scan on the target system, but bypass host discovery. (Host discovery uses ping, but many server firewalls do not respond to ping requests. This option forces the test without waiting for a reply that may not be coming): nmap –Pn –F The nmap utility can be used to detect the operating system of a particular target: nmap –A It can also be used to probe for the services that might be using different ports: nmap –sV ➡️ Follow me on Twitter My Ada handle: $cryptotech ⚠️I’m not a financial adviser and this video is for educational purpose only⚠️ You can support my channel by donating crypto, or use my affiliated link to KuCoin or coinbase exchange, every donation is appreciated.
