the wireless card of our Windows computer, and then we can use Wireshark to capture all the network data of this wireless card, including the network communication data of our iphone. Through my actual test, this idea is completely feasible. Here we need to use two software, one is the wireshark mentioned above, and t

Today just applied for a virtual host, upload data to become a problem, Google, hehe, see the FLASHFXP This software, this is called What ghost Things, forgive the English rotten to the extreme, download installation, recently happened to the agreement analysis is very interested Ah, so, This is the Virgo article today, hehe, the individual always love to say some nonsense, well, if you think so, then let's get to the point.

Common packet-capture analysis tools are: Microsoft's Network Monitor and message Analyzer, Sniff,wsexplorer,SpyNet,iptools, Tools such as Winnetcap, WinSock Expert,Wireshark, and Linux tcpdumpToday, did the experimental Test on the comparative analysis of two of them, others can be Baidu Google test a ha ^_^1.

But here's the problem is, if you meet with SSL/TLS and other encryption means to encrypt the network data, often we can only be helpless. In the past, if we had the private key of the transfer session, we could stil

Wireshark, formerly known as ethereal, is an amazing network monitoring tool. It helps you to capture the data packets being sent/received by your network interface and analyze it. Warning:Before using Wireshark in promiscuous mode Make sure that you have the required permissions to do so. promiscuous Mode, in a way,

Check that you can use Tracert to find routing changes between the source and destination addresses. If you can do this on your company's internal network, for example, configure a trap on the router . Data Capture Issues : The message may be sent or received normally, but
