To analyze the host 222.26.28.73, intuitive judgment for the Linux systemTo analyze the host 222.26.28.122, visually determine the Microsoft systemTo analyze the host 222.26.28.228, it is not intuitive to judge that no TCP port is closed, and no port is closed, all filtered. Description You can establish a

Packet Capture analysis tool-tcpdump Tcpdump (dump the traffic on a network) is a more practical tool for analyzing data packets in Unix, it supports filtering at the network layer, protocol, host, network or port, and provides logical statements such as and, or, not, and boolean expressions for packet header matching, in Linux, you can use yum to install yum if

Android simulator BlueStacks + TCPdump analyzes APP packet capture and bluestackstcpdump Recently, I want to analyze Android APP packet capture. I found some methods on the Internet, which is the most convenient for Android simulator + tcpdump in combination with my own conditions. Tools required: 1. Microsoft. NET Fra

OverviewTCP is a reliable connection-oriented transport protocol, two processes to send data before the need

Due to a large number of customers under the core of the room, which unavoidably many large customers, is so-called tall tree catches, the recent computer room some customers are always traffic attacks, the prevention method can only be found specifically attacked IP address, and then in the upper core of the IP configuration of the empty route will attack traffic interception in the backbone layer, so as not to affect the normal use , at present, I have done a mirror port at each core, the upli

I. Overview:After listening to the ASA video from yeslab's instructor QIN Ke, the FTP server is on the Outside and the FTP client is on the Inside. In this case, the active FTP server works normally because: ftp review can enable FTP to normally Modify FTP application layer data when traversing PAT), and enable FTP to actively initiate packets from Outside to Inside in active mode to pass the firewall smoothly. Because the configuration of PAT on the vro and FTP work normally, we plan to test wh

vswitch, connect one by one, and check whether the connection is normal until the connection is interrupted. Then we can determine which network cable is faulty, find the problematic host through the network cable. . Virus detection and removal can generally solve the problem. However, we can see that this workload is very large. If there are enough switches and there are more than one faulty computer, it will take a long time for us to completely solve the network problem. However, we have a t
