    Errors committed by the novice user as a Linux system administrator.

    Using the Linux operating system is really easy and pleasurable for some user and side by side it can be said that it is nightmare for some other users. To be more precise Linux is a nightmare for the novice users. Actually I am also novice user to this Linux environment and I want to know the common errors committed by the novice user as a Linux system administrator to avoid the problems like these.

    At first glance, this may be a good idea. If you are running Ubuntu, you will know that package management program using the. deb package. However, you find many applications in the form of source code are provided. No problem? These programs installed may be able to work properly. But why cannot you free to install process? The reason is very simple, if you are to the source in the form of installation of the program, then your package management system will not be able to track what you have installed. Therefore, the package “A” (in the form of the source installation) depends on package “B” (from a. Deb library installed), while package B is updated when the Update Manager, what would happen then? Package “A” may run, it may not run. deb repository to install, then both the opportunity to be able to run higher. In addition, all packages are based on the same binary type; the update package will be easier.

    If a permission to configure properly will give hackers an opportunity to leave. Dealing with licensing issues, the easiest way is to use the so-called RWE approach, that is Read (read), Write (write), Execute (execution). Suppose you want a user to read a file but cannot write to a file. To do this, you can run:
    chmod u + w, u-rx filename
    Some new users may see an error, saying that they did not use the file permission, so they are used: Chmod 777 filename, that this can avoid problems. However, this will actually lead to more problems, because it gives the file executable permissions. Remember this point: 777 to a file read, write permission to the implementation of all users, 666 will be a file read, write permissions to all users, while the 555 will be the file read, execute permissions to all users, there are 444,333,222,111 and so on.

    There is no installation of a running kernel

    You may not be installed on a machine more than 10 cores. But you need to update the kernel; this update does not remove the previous kernel. You have to keep using the most recent kernel that can work properly. Suppose your current working kernel is 2.6.22, and 2.6.20 is a backup kernel. If you have updated to 2.6.26, but in the new kernel, everything is working properly, you can remove the 2.6.20 had.

    Avoid using the command line

    I am afraid that very few people are willing to remember so many commands. In most cases, the graphical user interface is many people's favorite. However, sometimes the command line easier to use, fast, safe and reliable. To avoid using the Linux command line is the management of taboo. Administrators should at least understand that the command line is how they work, or at least still have some important management commands.
