Nmap Scan in Terminal



nmap scan tutorial computers / servers / networks


Remember, scan on your own computers / servers / networks. I will just cover the basic of nmap scanning. 1. type nmap -T4 -sV -v -O --version-light (then the targets ip) in terminal



ote: The -T4 means timing table, we are setting it to 4 because we dont want it too take long and we want to be aggressive! : The -sV is service version detection : The -v is a verbose output : The -O Detect operating system (TCP/IP fingerprinting) : Then we have --version light, it means it will reduce the total number of probes that are most likely to work! 2. when we go to put the target ip in we change it to xxx.xxx.x.1-255 or if you want to scan a particular ip just put in their ip 3. Some common options you want to learn are things like: -sS, -sT, sU, -vv, -A, -T, -P, -F, -n....... 4. to learn how to use namp well you also should learn about ports! Example 20 FTP data (File Transfer protocol)N
