wireshark port scan

TCP connection scanning, based on sockets, uses threading to implement multi-threading and to control the number of processes.Note: The Threads_limit variable depends on the host, and there are too many definitions to make the following error:650) this.width=650; "Src=" Http://s2.51cto.com/wyfs02/M00/86/F2/wKiom1fPfPGTqgnjAAAL7L75bGQ904.png-wh_500x0-wm_3 -wmp_4-s_3950277187.png "title=" 1.png "alt=" Wkiom1fpfpgtqgnjaaal7l75bgq904.png-wh_50 "/>Code:Importsocketimportthreading#changethesevars.star

There are now port-proof tools, such as Psad, Portsentry, but feel the configuration is a bit cumbersome, and the server does not want to install an additional software. So I wrote a shell script to implement this function. The basic idea is: the use of iptables recent module records in 60 Seconds to scan over 10 ports of IP, and combined with the Inotify-tools tool real-time monitoring iptables log, once t

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 5 seconds The rest of the window is the relat

Number of Windows Scan Port links batch Because we have a problem with the disconnected development of a program here, there are often thousands of links in the established state, but in fact these links should have been disconnected, when the link piled up to a certain extent, the server can not access the situation. That's why the following script was generated. The purpose of the script is to make a st
