Small white Diary Active information collection of 8:kali penetration Test (ii) three-layer discovery: Ping, traceroute, Scapy, Nmap, fping, hping

Layer three discovery three layer protocols are: IP and ICMP Protocol (Internet Management Protocol). ICMP is used to implement intenet management, path discovery, network communication, or target host status, and the ICMP protocol is used primarily in three-layer discovery. The ARP protocol belongs to the two layer protocol, which is broadcast-based and therefore not routable. While the ICMP protocol can be routed, in theory, the ICMP protocol can be used to discover the global IP, if there is

Nmap Advanced Scan Usage

NMAP provides four basic functions (host discovery, port scanning, service and version detection, OS detection) and a rich scripting library. Nmap can be used for simple network information scanning, but also in high-level, complex, specific environment: such as scanning a large number of hosts on the Internet, bypassing the firewall/ids/ips, scanning web sites, scanning routers and so on.Briefly review
