Through the/proc/net/dev can be viewed to the network card traffic, according to the changes in the value of the file in conjunction with while loop write a real-time monitoring network card script, by specifying the network card
In the Hyper-V 3 of Windows Server 2012, a series of new features is called, such as the network card traffic throttling feature.
Infrastructure-aware issues
During the hosting server planning process, administrators mainly consider the CPU, memory, disk space, and other necessary factors in the server infrastructure, but the network adapter (NIC) is usually a
Now more and more users have installed Vista system, a lot of friends said in the Vista set up wireless network card more trouble, can not start. The following I teach you how to set up in Vista system wireless network card and wireless Broadband router wireless connection, so that you immediately enjoy the pleasure of
Often hear netizens complain wireless network card is not on the net off line, this is a very common fault, first of all, we have to start from the network card driver problem, after the elimination of the driver should consider the problem of software settings, the following detailed description of the solution, hope
You should have a lot of knowledge about wireless network interfaces. The next step is to explain how to upgrade the built-in wireless network card. First, you need to understand the internal structure of the notebook, you need to "Anatomy" the laptop before it involves wireless network
Failure phenomenon: A new computer network card access to the local area network, the speed of startup slow.
Fault analysis and elimination: According to the fault analysis, this failure may be set in the TCP/IP settings of the network card "automatic get LP address" caused

I have heard of network accelerators for a long time, but I have always felt that optimization of some algorithms by software is definitely impossible to increase the performance statistics by an order of magnitude. I must have some hardware help, even a Cisco professional-level device uses a large number of ASIC chips to forward packets. In fact, it uses a hardware cache mechanism. If these hardware
A WIN7 via USB without a line by the Internet, the other using a crossover line connected to, if you have two simultaneous access to the Internet, you can use the bridge, the following methods:Taking the author's network as an example, The use of the network segment is 192.168.1.X, one of the desktop has been able to access the Internet, the network
of radio towers, welding machines, trams or high-voltage power transformers, such as signal interference sources, can enable users to receive clutter (copper clad steel wire shielding weak, strong reception capacity), the user line caused strong interference. The jamming signal is often the unshielded part of the wire entry, because the relay cable has a shielding layer, interference and impact are very small. If the interference in a large place with a number of shielded off the line, it will
a Cisco Professional-level device uses a large number of ASIC chips to forward packets. In fact, it uses a hardware cache mechanism. If these hardware can also be inserted into the gateway running Linux, the network forwarding performance of Linux will inevitably be greatly improved. However, hardware insertion is very simple. How can we make the software work with the hardware? We know that the combination of hardware and no software is a pile of wa

Linux every time you start the network card must be activated to the Internet, it is very troublesome.
On the Internet to find information, and finally this solution:
# vi/etc/sysconfig/network-scripts/ifcfg-eth0:1 View the eth0:1 configuration file.
All said that there is onboot=yes this sentence can start automatic activation, but the configuration file clearly
Because the kernel 3.0 does not support 9300 Series network card, need to modify the kernel, more trouble. Therefore, the direct use of Compat Open source driver code, because the latest 4.1, 4.2 version of the bug compiled run after the problem, the current use of the 4.0.1-1 version backports-4.0.1-1.
