Howto's

Have you ever been in a situation where you are boasting about Linux in front of all your windower friends and then after getting bored of your long lecture someone asks you to shut up and create a network with shared Internet so that they can work on their sucky systems(according to you) atleast then, leaving you staring at the roof wondering, "how the hell is this done"? . If yes, then here is a solution.

So, I installed CentOS yesterday and I never expected but installing it was a pretty good experience. Since, its mostly used as a server, it asks you in the beginning what kind of work this machine would be doing - Servers(dns/http etc.), virtualization or others. Basically, marking the appropriate packages to install before hand. This went great, but when I finally logged into it system for the first time, the default graphics performance was terrible.

While using Wget in scripts or otherwise, mostly when there is a lot of content to be downloaded, we need to set wget's network usage and bandwidth parameters. They both default to unlimited and when there is a lot of download involved, its always a good practice to set the limits. In this article, we will see how to control the bandwidth rate and total usage(quota).

Whenever I go to home on vacations, I usually share a lot of Music/Videos with my friends. On many occasions, my laptop is being used by someone else and since its a personal notebook, there is a lot of stuff I don't want people to mess around with. Under such cases, restricting other users by locking stuff comes in handy.

Since, most of my hometown friends are neither really techie nor even Linux users, a simple change in file permissions does the trick.

Managing users is an important activity in Linux. For a Sysadmin, you want different access permissions for developers, maintainers and moderators. Groups are an easy way to categorize users. Rights/permissions given to a group will be applicable to all its members. In this howto, I will tell you how to add users to a group.

I would suggest you to read about the two types of groups - Primary and Secondary, before proceeding.
