Plus-S 0 can catch complete packets(5)-C 100: Fetch only 100 packets(6) DST Port! 22: Packets that do not crawl the destination port are 22(7) SRC net 192.168.1.0/24: The source network address of the packet is 192.168.1.0/24(8)-W./target.cap: Save as a cap file for easy analysis with ethereal (i.e. Wireshark)Http://www.cnblogs.com/ggjucheng/
One, the most commonly used for Wireshark is the filtering of IP addresses. There are several cases: (1) The filter of the packet with the source address 192.168.0.1, that is, the packet fetching the source address to meet the requirement. The expression is: ip.src = = 192.168.0.1 (2) filters the packets that have the destination address 192.168.0.1, that is, the packet fetching the destinatio

Secure Socket Layer, SSL based HTTP protocol), port 443, need to request a certificate from the CA, the SSL handshake to establish a secure channel, The data is symmetric encrypted by using the negotiation key. Using Wireshark to filter SSL traffic, you can see several obvious SSL session creation packages, such as client hello,server hello; First send ClientH

frame into a Ethernet frame and then give kernel, so kernel the protocol stack is better handled. The question is, if I want to hear the WiFi frame, how do I do it? The answer is simple, set the WiFi adapter Monitor mode. In WiFi adapter, there is usually a ssid/essid filter, so it is not useful to set the WiFi adapter to promiscuous mode, because it is still impossible to receive a frame that is not a par
filteringThe use of filtering is very important, when beginners use Wireshark, will get a lot of redundant information, in thousands of or even tens of thousands of records, so that it is difficult to find the part of their own. Filters help us quickly find the information we need in a large amount of data.There are two types of filters:One is the display filter, which is the one on the main interface, whi
