nmap syn scan
SYN scan is the default and most popular scan option for good reasons. It can be performed quickly, scanning thousands of ports per second on a fast network not hampered by restrictive firewalls. It is also relatively unobtrusive and stealthy since it nev,跳到 TCP SYN (half open) scanning - TCP SYN scanning : This technique is often referred to as "half-open" scanning, because you don't open a full TCP connection. You send a SYN packet, as if you are going to open a real connection and wait fo,SYN or Stealth scanning makes use of this procedure by sending a SYN packet and looking at the response. If SYN/ACK is sent back, the port is open and the remote end is trying to open a TCP connection. The scanner then sends an RST to tear down the connec,nmap -v scanme.nmap.org. This option scans all reserved TCP ports on the machine scanme.nmap.org . The -v option enables verbose mode. nmap -sS -O scanme.nmap.org/24.
