Einzelne Portnummern sind okay, ebenso wie mit einem Bindestrich getrennte Bereiche (z.B. 1-1023 )
  2. Launches a TCP port scan of the most popular 1,000 ports listed in nmap-services. A SYN stealth scan is usually used, but connect scan is substituted instead for non-root Unix users who lack the privileges necessary to send raw packets. Prints the results to standard output in normal human-readable format, and exits
  3. Hier eine Gedächtnisstütze: Optionen für Port-Scan-Methoden haben die Form -s<C>, wobei <C> ein bedeutender Buchstabe im Scan-Namen ist, normalerweise der erste. Die eine Ausnahme hiervon ist der als veraltet betrachtete FTP-Bounce-Scan (-b). Nmap führt standardmäßig einen SYN-Scan durch, ersetzt diesen aber mit einem Connect-Scan, falls der Benutzer nicht die nötigen Rechte hat, um rohe Pakete (benötigen unter Unix root-Rechte) zu senden, oder falls er IPv6-Ziele angegeben hat. Von.
  4. Nmap is a very effective port scanner, known as the de-facto tool for finding open ports and services. Nmap performs several phases in order to achieve its purpose: 1
  5. Tutorial Scan ports using Stealth Scan on Nmap Stealth Scan is also known as SYN Scan or TCP SYN Scan because it sends only one SYN packet in the TCP Handshake process. This speed of operation and lack of communication is good for the scanner to prevent traffic analysis. Because there is no complete connection that anyone wants to analyze
