have any mistakes, please correct me. We recommend that you use source insight (www.soucedyn.com) to create a project and check the code at the same time, which may be better. I have also used some other tools, but when analyzing a large amount of code, no tool is more convenient than it. 2 Text The layer-7 model of ISO is very familiar. Of course, it is more suitable to use a layer-4 model for the Internet. In these two models,

Installation of network data collection and analysis tool TcpDump In linux, the installation of tcpdump is very simple. Generally, there are two installation methods. An rpm Package is used for installation. In addition, it is installed in the form of a source prog

while checking the log file, and you are sure that this user does not have an account on this host, you may be attacked. First, you need to lock the account immediately (in the password file or shadow file, add an Ib or other character before the user's password ). If the attacker has been connected to the system, you should immediately disconnect the physical connection between the host and the network. If possible, you need to further

laptops. Similar to GNOME Network Manager, Wicd Supports Wireless and wired networks and is compatible with most encryption solutions. Compared with the GNOME Network Manager, Wicd allows you to choose your own encryption solution. One of the most convenient aspects of Wicd is that it does not rely on the default Gnome or KDE tool of the system, which makes it easier to use. 3. Wifi-wiz that can be run in

(CPU execution Time), the proportion of time spent by the three is about 250: 30: 1, which is based on the packet size of bytes. The larger the ratio of the three, the longer the transmission (or receipt) and DMA packets are the time bottlenecks. During interrupt processing, it takes a little longer to "New packets arrive" than "packet transfer completed. Keywords: Linux, Protocol driver, network card driv

This article mainly faces the new novice, does not have any high difficulty question discussion, including the double network card, the normal compilation driver also cannot use the strange network card and so on. The main purpose of this article is to tell the new novice, Linux under the network card is how to drive.

As a necessary tool for the classic system administrator on the internet, tcpdump, with its powerful functions and flexible interception policies, becomes one of the essential tasks for every senior system administrator to analyze the network and troubleshoot problems. Tcpdump provides source code and open interfaces, so it has high scalability and is a very useful tool for net
