linux control fan speed

Check the NIC working mode and speed of the linux system. Sometimes, we need to check the NIC working mode and speed of the linux system. The commonly used commands are mii-tool and ethtool, let's take a look at the following. View eth0 Nic information at www.2cto.com [root @ cloud ~] # Mii-tool-v affinity: negotiated

Many computer geeks know they can use speedtest.net to test speed, but this does not give you enough control over the test. Linux users like to enter commands in the terminal to complete the task, at least that's what I am. Tespeed is a python tool with a lot of features that you can test at the end of the Internet. According to the documentation, it leverages t

I have always been in the Windows platform, with SSH and VNC to remotely control the Linux broiler to achieve NT and *inux system environment work. This specific implementation of the network tutorial has been a lot, I think there is no need to explain the details of the pull. But lately because it really hates Microsoft to launch the so-called 2003, and it is said that the total limit, so that I can not ha

. Linux systems face the same problems as window, and how to control multiple versions of a dynamic library. To solve this problem, Linux has introduced a set of naming mechanisms to solve this problem, which can be avoided if this mechanism is followed. But it's an agreement, not a compulsion. However, it is recommended to adhere to this Convention, otherwise th

1 Preface With the rapid development of the Internet, the network is more and more widely used, and the network function requirements for various industrial control devices are also increasing. The current requirement is to allow industrial control devices to support TCP/IP and other Internet protocols, so that they can view the device status and set device parameters in a browser that users are familiar, o

1 IPMI OverviewIPMI provides a lot of rich functionality, and the features I use, say plain English, are:1, obtain the hardware information of this device: including CPU and motherboard temperature, voltage, fan speed.2, on device A, through the command, control remote device B, power on, shutdown, restart. (see if this is a little impulse to do bad things, haha)

The network environment of a server in the company is too high. when the server is connected to the source server for download, it runs to 400 M-500 M. in order to control the server, we studied TC. To control traffic. to control it to a small point, do not let this one occupy all the networks. TC is very powerful. many so-called hardware routes... The network e

stable after the window is always linear growth, The slow boot process is not performed again. Secondly, BIC-TCP's window control stage is divided into binary search increase, max probing, and then Smax and Smin, which increases the difficulty of the algorithm, and also adds complexity to the analysis model of protocol performance. In low-RTT networks and low-speed environments, the BIC may be too "aggress

TC IntroductionIn Linux, TC has two kinds of control methods CBQ and HTB. HTB is designed to replace CBQ. HTB is more flexible than CBQ, but CPU overhead is also greater, and usually high-speed links use CBQ, generally HTB used more broadly. HTB's rules are essentially a tree-like structure, consisting of three basic constituent blocks: The queue specifies Qdisc

Of course, any operation performed by windows can be viewed synchronously in Linux, and Lin
