Because Windows XP or 2003 has 20% of "reserved bandwidth," There is a corollary: removing the speed boost 20%,xp the bandwidth. These statements are popular on the internet, but you have to spend time and effort to remove this limitation, but found that the speed did not improve!
As far as I know, this method was originally from the Computer newspaper, until today this so-called "skill" is still widely cir
Under Linux, when we need to crawl network packet analysis, we usually use the Tcpdump crawl Network raw packet to a file, and then download it locally using the Wireshark Interface Network analysis tool for network packet analysis.Only recently found that the original Wireshark also provided with the Linux command line tool-tshark. Tshark not only has the function of grasping the package, but also has the

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

Wireshark basic usage and overhead rulesWireshark basic syntax, basic usage, and packet forwarding rules:1. Filter IP addresses. For example, the source IP address or target IP address is equal to an IP address.Example: ip. src eq 192.168.1.107 or ip. dst eq 192.168.1.107 or ip. addr eq 192.168.1.107 // both the source IP address and target IP address are displayed.
