Probe into the scapy of network scan big kill device in Python Recently experienced twisted blow, this network programming really do not understand, can not touch its internal logic, it seems that network programming is not so good to get. Fortunately, see the scapy, this

Linux has a lot of powerful network scanning tools, network scanning tools can be divided into: host scanning, host service scanning, route scanning and so on.Fping is a host scan tool that can scan hosts in batches compared to the Ping tool.Fping Official website: http://fping.org/Fping source code compilation and ins

Do not need any tools, DOS command scan all the ports of a network segment! Open a DOS window under Win2000, and then execute FOR/L%a in (1,1,254) do start/min/low telnet 192.168.0.%a 3389 So all the open 3389 ports in this 192.168.0.x segment will be exposed. After this command is executed will open 254 small windows in the taskbar Then the Telnet link failed window automatically exits after approximately

In addition to the previous article "Linux Common Network Tools: Route scanning traceroute" introduced in the Traceroute, General Linux also built-in another common route scanning Tool mtr.The MTR is better used in some ways than traceroute, and it can display the information of each hop routing in real time and constantly probe.Traceroute uses UDP packet probing by default, and the MTR uses ICMP packet detection by default, and ICMP has a lower prior

Netcat, also known as the Swiss Army Knife, is a common network tool for hackers and system administrators, originally developed for file transfer and later developed many powerful features, such as the ability to perform bulk host service scans.Previously, another more common scanning tool for bulk host services was introduced: Nmap.The installation of the Netcat is also very simple, with the direct Yum installation:Yum Install NCIn general, it is no
