The development of high efficiency, simple syntax, for dynamic Web sites tailored to strengthen the object-oriented (to C + +, and Java to build a point), but a single thread (this is the Achilles ' heel, it is said that PHP is written with c\c++.) ), can also use C, C + +, Java development of the middle tier, call COM, server maintenan

Long time did not write Java, learning, also did not learn network programming this piece, inadvertently saw a book, so a little review of Java, write a port scanner, play it, online this little public has is, is his boring write play.The source code is as follows:A total of two categories, relatively simple AustrianImportjavax.swing.*;Importjava.awt.Dimension;Im

Idea: Use the socket for connection testing, where the client connects to the server.The core code is as follows:From socket import *def try_port (Ip,port,protocol = sock_stream): s = socket (Af_inet,protocol) Try:s.connect ((str (IP), int (port)) ) return Trueexcept:return falsefinally:s.close ()　　Call Method:1.

Port Scan 234 Layer discovery is only to accurately discover all live host IP, identify attack surface, port scan to discover attack point, Discover open port. The port corresponds to the Network service and application program, and the vulnerability of the service-side program is hacked through the

I. Overview Task Description: Develop a program to obtain a list of host IP addresses for the SNMP service on the LAN and write the corresponding files for use by other programs. Background knowledge: SNMP is UDP-based, and the standard SNMP service uses 161 and 162 ports. Ideas: 1, get the local area online host list; 2, get the SNMP port of each host (for examp
