This includes many port scanning mechanisms (both TCP UDP), OS detection, version detection, ping sweeps, and more. nmap nmap nmap-Nping Nping is an open source tool for network packet generation, response analysis and response time measurement. Nping allows to generate network packets of a wide range of protocols, letting users to tune virtually any field of the protocol headers. nmap-ncat Ncat is a feature-packed networking utility which reads and writes data across networks from the command line. Ncat was written for the Nmap Project as a much-improved reimplementation of the venerable Netcat. nmap-ncrack Ncrack is a high-speed network authentication cracking tool. It was built to help companies secure their networks by proactively testing all their hosts and networking devices for poor passwords. DNS网络侦察 The purpose of Dnsenum is to gather as much information as possible about a domain. The program currently performs the following operations: 1) Get the hosts addres
