As the name suggests, tcpdump can completely intercept the "Header" of the packets transmitted in the network for analysis. It supports filtering network layer, protocol, host, network or port, and provides logical statements such as and, or, not to help you remove useless information. Tcpdump is a free

Many friends may encounter some problems when using network protocol analysis software. Some problems may occur during the installation of network protocol analysis software. Some people often ask why I can only see my own communication? Why can't I see the Communication Status of XX? Is it software limitations? In fac

Wireshark packet capture analysis-network protocol Wireshark is currently the most popular packet capture tool. It can run in windows, Linux, and Mac OS X operating systems, and provides a friendly graphical interface. Wireshark also provides a powerful data packet capture function. It can capture the network data packets required by users in various ways. Howeve

of network transmission media and technical level, the network speed will be limited. For example, we used to use a modem to dial up the Internet over a telephone line at a speed of 54 kbps. Now most users access the Internet through ADSL, the network speed is usually 1-3 Mbps (related to the services provided by the local carrier). The fiber optic access can re

are relatively independentThe interfaces between the protocol layers are clearer, and there are fewer cross interfaces.Easy to implementThe Open Communication System Interconnection Reference Model (OSI) adopts a layer-7 protocol architecture with low efficiency. The TCP/IP protocol is an improved model based on the OSI model and uses a layer-5 protocol architecture, the TCP/IP model architecture 1 is shown in.Iii. TCP/IP network security

The network structure is complex and changeable. All kinds of network protocols are difficult to grasp, let alone applications. Here we can use the network protocol analysis software for management. Some people often ask why I can only see my own communication? Why can't I see the Communication Status of XX? Is it soft

Summary Starting from the analysis of GSM spectrum efficiency, this paper analyzes the loss of spectrum efficiency of voice service after the GSM network is upgraded to GPRS, and the new data service access ability, and finally takes into account the maximum access ability of the integrated service under GSM current spectrum from the mutual substitution between voice and data service access ability. GPRS

Ike Nassi, Technical Director of Firetide networks, added: "Our mesh network solution simplifies installation and just needs to be connected to the AC power supply. Th

preferred DNS server. It is best to add a domain name resolution system address closest to us, so that, for example, any webpage domain name address we enter when accessing the Internet will be converted to an IP address immediately, then, compress the IP address of the website on the Internet. You can download the addresses of China Netcom and China Telecom's main DNS servers from the Internet. ※Reference: http://gaofeilonglcu.blog.163.com/blog/static/1308642912010953495956/ (1) Problem

In our well-designed campus network, if the network is suddenly slow, in the teaching time of important data, the response time left to the system administrator is only more than 10 minutes or even a few minutes. Also, the worm's impact on the speed of the network is getting worse, for example, "network Sky" and other

For cabinets, adequate cable channels must be provided to ensure that the Network cables can be accessed from the top and bottom of the cabinets. In addition, this reduces the space occupation of cables, ensures that the equipment installation, adjustment
