In this article, small knitting and readers to talk about Rspan technology, this technology small series like Ah, for a network management personnel, in order to ensure intranet server security, you can not keep a bunch of servers every day, Rspan technology plus related monitoring software can help you to dynamically monitor intranet server, Here small weave uses Huawei's equipment to realize.
The switch that implements the Rspan function is divided
Nethogs is a small, free open source command-line tool used to count network bandwidth usage in real time by process or program.For use similar to "repo tool", "Depot_tools" and other tools checkout source code is very useful, you can view the current download speed information, so you do not blindly wait.Installation under Ubuntu system
sudo apt-get install Nethogs
How to use

Sometimes we need a more real-time view of the network card traffic on the server, here I wrote two small script, one with the shell (first, only one network card can be viewed at a time), another in Python (after writing, can view more than one network card).
In the script all use the while true "dead loop", every 10
, provide the ability to specify the access rate, the security shielding capability of ACL (Access Control List), the network traffic statistics and monitoring capability, and the support capability of Policy Routing (PBR, can more effectively determine the intelligence of the network. Therefore, the edge Layer 2 switching equipment in a foldable backbone is an e
ParametersThe following is the Nethogs command line parameter, with '-d ' to add the refresh frequency parameter, ' device name ' is used to detect the bandwidth of a given or some device (default is eth0). For example: To set the refresh rate for 5 seconds, type the following command:# nethogs-d 5If only the network bandwidth used to monitor the device (eth0) can use the following command:# nethogs Eth0If you want to monitor both the eth0 and ETH1 i
In Linux/Unix-like systems, you can use top to view system resources, processes, memory usage, and other information. To view the network status, you can use tools such as netstat and nmap. To view real-time network traffic and monitor TCP/IP connections, you can use iftop. What is iftop? Iftop is mainly used to display the n
Why do I use Netem to do a flow controlBut when sending, feel really send the data when still did not reach every packet is a 1s delay ah, here the 1s delay is what mean ah?The delay here is not to say that each packet is delay 5s, but that after delay5s, all of a sudden sent out?sudo tc qdisc add dev eth0 root netem delay 100sAll eth0 packets have to be delayed by 100s, starting with the queue, and we start timing, because all of the packets are in the first place on the waiting queue, and so i
Found in the work, often because of business reasons, need to know the traffic of a server network card, although the company also deployed cacti software, but the cacti is five minutes statistics, no instant, and sometimes open the monitoring page inconvenient, personal like to easily enter a command on a server, View network card Instant
Network traffic control is a very important part of LAN maintenance. It mainly involves the following methods:
1. Use a mask to divide the network segments into different network segments. This reduces the number of network broadcasts and enables fast communication between n
