Beyond the basic port scanning, Nmap offers various specialized scan options that cover specific scenarios. Let’s discuss some of these scenarios: You can reduce the number of probes that Nmap sends by using the --version-intensity option. This option takes an integer argument between 1 and 9, limiting the number of probes sent to open ports to those with a rarity of that number or less..

The basics that you need to scan TCP ports are relatively simple. The basic structure you need is “nmap [type of scan] [options] {target specification}”. For scanning TCP ports you’ll want to use one of two scan types, TCP or SYN. A TCP scan attempts to make a full connection to each port, completing the three-way handshake. Mar 6, 2018 · Here’s one of the methods description (“ TCP connect scan ”): The client sends the first handshake using the SYN flag and port to connect to the server in a TCP packet. If the server responds with a RST instead of a SYN-ACK, then that particular port is closed on the server. And one more method (“ TCP stealth scan ”): RustScan is a tool that turns a 17 minutes Nmap scan into 19 seconds. RustScan tool is developed in the Rust language and valid on the GitHub platform.
