Preface:Recently, to build the strongswan environment, Wireshark is required to capture packets. One computer is always unable to access the network (only through the LAN), and cannot directly apt-get. So I studied the following software installation methods, especially in Ubuntu, how can I directly copy and install the installation package like in windows. This article is available. I,In ubuntuThere are generally two software installation formats(D

The following steps will rectify this. Sudo usermod-a-g Wireshark zhangbin Sudo chgrp

wireshark----teach you how to grab a bag .Wireshark is a powerful grab bag tool, pass by must not miss is, when you learn the TCP/IP protocol, learning to use Wireshark grab bag is the best method of theory and practice, first about the agreement, Then crawl the various protocol packets to analyze each byte to correspond to the encapsulation of each layer of prot

Recently, when learning the NIC driver, we need to capture the situations where the Nic sends and receives data. so we found the tcpdump and wireshark tools, which are used to capture data, wireshark is used to analyze the captured data. the usage is recorded below: Tcpdump usage method (1) first, key words about the type mainly include host, net recently, when learning the NIC driver, you need to capture t

Do application identification this piece is often used to analyze the data traffic generated by the application.Grab the bag using Wireshark, extract features, to the session to filter, find the key stream, here summarizes the basic syntax of wireshark filtering, for their future reference. (The brain can't remember anything)Wireshark filtering can be divided int

The main network elements in the Ethernet network include switches, routers, firewalls, servers, and clients. By testing the Ethernet network elements and the network itself, the network structure can be optimized, the network fault is eliminated and the network performance is mastered. Ethernet testing is also rule-based, such as the well-known rfc2544/rfc1242,

The development of the exchange technology has become mature. At the same time, driven by telecom operators, the Ethernet exchange technology has been fully applied and its role has become more obvious. With the development of network technology and the popularization of Information Application, Ethernet Switching technology has been widely used. More importantly, it began to penetrate from simple lan appli

There are many things worth learning about Ethernet switches. Here we mainly introduce the new development direction of Ethernet switches. At present, more and more manufacturers are entering the Ethernet market, new brands and new products are emerging, and there seems to be a trend of Homogeneous Competition. However, it is worth mentioning that, as the number

Many people may not quite understand the switched Ethernet technology. First of all, let everyone know from bridges, multi-port bridges to switches, then we will introduce the working principle of the switched Ethernet technology and the advantages of the switched Ethernet technology. Ethernet machine, which is a SWITC

There are many things worth learning about Ethernet switches. Here we mainly introduce Ethernet switch configurations and network types. Rack-mounted switch, fixed configuration with/without expansion slot) rack-mounted switch is a slot type switch, which has good scalability and supports different network types, such as Ethernet, fast

community properties.The Intelligent Community Information system can be divided into two parts of information network subsystem and control network subsystem from function.The Information network subsystem is composed of data system, voice system, CATV system, on the one hand realizes the comprehensive access of data, voice and image, on the other hand provides the transmission channel for the control network subsystem, its transmission way is flexible, can be FTTB +lan, ADSL, HFC, can also be

The internet has grown rapidly with e-mail and www Two free services, prompting rapid growth of Ethernet. Now more and more manufacturers to enter the Ethernet market, new brands and new products continue to emerge, it seems that there has been a trend of homogenization of competition. However, the expansion of the Ethernet switch in the market at the same time,

The history of optical communication with light wave as information carrier is a long-standing one, the atmospheric laser communication is the communication of the atmosphere as the transmission medium, and it is the first kind of communication method developed after the laser appears. Because it has the advantages of long-distance transmission distance, frequency bandwidth, small transmitting antenna, good confidentiality and electromagnetic interference, more and more attentions are paid to it

Metro Ethernet is still commonly used. So I have studied the case study on environmental optimization of Metro Ethernet. Here I will share it with you and hope it will be useful to you. Before implementing this optimization scheme, the access layer switches in the current network come to three aggregation layer Ethernet switches Aggregate-1, Aggregate-2 and Aggre
