linux sniff network traffic

nagios is not monitored by default Windows Plug-in for network card traffic, but can be implemented through a third-party plug-in script. 1: Download the check_traffic.sh script and upload it to the/usr/local/nagios/libexec directory of the Nagios monitoring server.Official: Https://github.com/cloved/check_traffic2: Execute permissions for check_traffic.sh:#chmod a+x/usr/local/nagios/libexec/check_traffic.s

network card, cannot limit the packets received by the network card, so we can change the sending order to control the transmission rate. Linux traffic control is mainly processed and implemented when the output interface is arranged.Second, TC rules1. Flow control modeFlow control includes the following methods:SHAPI

Overview: The network Silver payment interface and Alipay interface is roughly the same, the main difference is that the bank of communications to provide the core of the interface, such as encryption, such as through the Java implementation. So, to find a way to make PHP and Java normal communication, for this. The authorities also provide two implementations, one for communication via sockets and the other for Java bridging. The socket method is sho

As we all know, at the beginning of the birth of the Internet are all universities and scientific research institutions communicate with each other, and there is no network traffic control considerations and design, the principle of IP protocol is as good as possible for all data flow services, different data flow is equal. However, years of practice have shown that this principle is not ideal, and some dat

Linux traffic control, and gives several representative examples.First, related conceptsIt can be seen that packet packets from the input network card (portal) received in, through the search to determine whether it is sent to the local, or need to be forwarded. If it is sent to the local, it is directly up to the upper layer of the Protocol, such as TCP, if it

For Linux, we often need to check the traffic of Linux traffic monitoring. Linux traffic monitoring is still quite common. So I studied some methods of Linux

New book Unix/Linux Log Analysis and traffic monitoring is coming soon The new book "Unix/Linux Log Analysis and traffic monitoring" is about to release the 0.75 million-word book created in three years. It has been approved by the publishing house today and will be published soon. This book provides a comprehensive an
