version of the software package. So how do System Administrators know the latest software versions and security vulnerabilities? I recommend to RedHat support website (https://www.redhat.com/apps/support ). Generally, after receiving a notification about a security vulnerability, RedHat finds a solution in the shortest possible time, publish and connect the latest software package on the Technical Support Platform. Generally, you can find the latest software version on the Linux operating syste

information when you start linxu. 　　 　　 Get started with a simple application 　　 We use a floppy disk to start a linux system with only one serial port and keyboard input to display the output x86 architecture. The specific application executed is to run minicom and dial through the serial port. Software required: minicom-xx.src.tar.gz and syslinux-xx.tar.gz, xx represents the version number, before starting, create a directory in the home directory

Recently in the "do-it-yourself-write operating system" Yu Yu, see the first page is covered, the book said to prepare a blank floppy disk, all 2010 years, where to find a floppy disk ah, since the contact with the computer I have not seen a floppy, it is estimated to go to the Science and Technology Museum to find it, hehe. In fact, in the second chapter-to buil

graphical compression decompression software Ark, but in today's eyeful is a RAR compressed document network World, the default ark but does not support the RAR format is really regrettable.But it doesn't matter, can go to http://www.rarsoft.com/download.htm download the official latest version of RAR for Linux, will download back to the compression package decompression, into the terminal, enter the "make" command to complete the installation. In this way, RAR for Linux automatically integrate

The following example illustrates how to consider all possible boundaries: -------------------------------------------------------------------------------- If the text input field can contain 1-characters. Try: Enter 1 character and 255 characters (valid range), or add 254 characters as valid test. Enter 0 characters and 256 characters as invalid intervals. -------------------------------------------------------------------------------- If t

Although the range of advanced CPU-managed memory has reached 16 MB (80286) and 4096 MB (80386, 80486), the DOS version has also been upgraded to 5.0, 6.0, 6.2 ..., However, to maintain compatibility with earlier versions of DOS, DOS still limits the memory space that users can directly use to kb, which is also called Basic memory.

Here we will introduce a little-known command in WINXP and win2000: syskey This command can effectively enhance your system security. Maybe you have to enter your account and password when entering XP or 2000. Isn't this safe? You should have heard of the famous Win2000 Input Method Vulnerability. If your computer is used by many people, others can access the system by breaking the simple password of others, attackers can exploit various vulnerabilities to obtain administrator privileges. Wi

Even if the file name contains a colon, the archive file is considered as a local file, generally, a colon indicates a remote host name.-H format, -- format = format uses the archive format. The valid format is listed below, which can be case sensitive. The default action of the "copy-in" mode is to automatically detect the archive format, and the default format of "copy-out" is "b

Use the structure in C language to implement bitwise segments-personal efforts! It's worth watching! The structure in C language has the ability to implement bit segments. Oh! You asked what form it is, right? You will be given an answer to this question. Let's take a look at the role of the bit segment: the bit segment is implemented by adding a colon and an integer representing the bit length after the field declaration. This usage is also called "D

A text Processing command and the TAR command use the Cat command to merge files verticallyVertical merge methods for both files:tar command: Put multiple files (which may also include directories, because the directory itself is also a file) in a tape or disk archive file.
