With the iis function, xp can go home and go to bed for me. But recently I am interested in linux, and I started to make a hard job again. I chose the linux Asian edition, that is, the as3 of the

commands to invoke the Mknod program, creating the corresponding primary and secondary number for each device that may exist in the world. When using the Udev method, only devices detected by the kernel will create device nodes for them. Because these device nodes are re-created every time the system starts, they are stored on the Tmpfs file system, the device node does not require a lot of disk space, and the memory consumed can be negligible. The Udev initialization script is responsi

Rev:1.0Type:direct-access ANSI SCSI Revision: GenevaHere, there are two direct-attached (direct-access) SCSI disks, a disc attached to the CD-ROM. We only consider SCSI disks, so the two disk locators in SCSI are 2:0:0:0 and 2:0:1:0. If you continue to insert a disk, then the new disk in the SCSI locator is 2:0:2:0, this value string is very important.1.1 Hot PlugAfter inserting a disk into a computer, the kernel does not generate any event notificat

At a.m. on June 23, December 2, the website www.w3counter.com published a series of statistics. The statistics on Vista users are as follows: Statistical Date: January 1, January 1, January 1, January 1 Proportion of users: 1.91%, 2.29%, 2.92%, 3.46%, 4.01%, 4.33% It is not hard to see that the number of Vista users is growing. However, the growth rate is decreasing slowly (the monthly growth difference is 0.4%, 0.6%, 0.5%, 0.5%, 0.3%, 0.4%), showing a significant downward trend. By the end

Sometimes we need to add hot-swappable SCSI hard drives to the online system, we cannot stop at this time, we can add the new hard disk to the system with the following instructions# echo "scsi add-single-device 0 0 1 0" >/PROC/SCSI/SCSI//Add HDD# echo "scsi remove-single-device 0 0 1 0" >/proc/scsi/scsi//delete HDDFor the four numbers in the directive, the SCSI, channel, ID, and LUN numbers, respectivelyWe can view this information for SCSI drives in

In this way, Uevent is uploaded to the user space and the module can be automatically loaded by matching the Modalias. Such bus examples are platform and i²c and

After a long period of development, many users are familiar with Hongqi Linux. Here I will share my personal understanding and discuss it with you. As Linux enters the computing environment of key industries, users' requirements for systems become increasingly strict. In order to meet this increasing requirement, Hongqi software has completely optimized the server operating system product line and launched
