linux sniff network traffic

There are many open-source network monitoring tools available on the web for Linux operating systems. For example:You can use the command iftop to check bandwidth usage, netstat to view interface statistics reports, and other tools BANDWIDTHD, speedometer, nethogs, Darkstat, Jnettop, Ifstat, Iptraf, Nload and ntop and so on.But these tools are statistical card access data, if you want to find a like 360 sec

Compared with nload, Iptraf is an excellent free small software that monitors network traffic of specific ports in linux. system environment: centos6.3Iptraf: iptraf-3.0.0 2. View dependency packages: # rpm-qa | grepgcc # rpm-qa | grepglibc # rpm-qa | gre Compared with nload, Iptraf is an excellent free small software that monitors

Use shell script to compute the Linux NIC traffic, the most critical point in the method: Copy Code code as follows: Ifconfig $eth _name | grep bytes | awk ' {print $} ' | Awk-f: ' {print $} ' The flow of input and output is obtained by Ifconfig eth0|grep bytes. Copy Code code as follows: /@rac2 =>dd2$ifconfig Eth0|grep bytes RX bytes:1638005313300 (1.4 TiB) TX

This article introduced Linux to see the network card traffic six methods, Linux system using Nload, Iftop, Iostat and other tools to view the network card traffic, here we first to explain the next Iptraf method, the need for a f

Https://www.ibm.com/developerworks/cn/linux/l-ipc/part4/ from Introduction:The traffic signal is not the same as that of other processes. It mainly provides resource access control for inter-process sharing. It is equivalent to a memory flag. A process can determine whether it can access some shared resources. At the same time, the process can modify the flag. In addition to access control, it can also be

Under Windows we can use the ipconfig command to obtain information about the network card, under Linux command is ifconfig We can obtain more information, including the network card to receive and send traffic, in the C language to achieve this command is not a simple matter, thus, the blogger through the access to r

For some reason you need to sniff HTTP web traffic (that is, HTTP requests and responses). For example, you might test the performance of a Web server, or X-Uy debug a Web application or restful service, or try to resolve a PAC (Proxy auto-configuration) problem, or check for any malicious files downloaded from a Web site. Whatever the reason, sniffing HTTP traffic
