Tutorial quote: This tutorial shows how to install MySecureShell on a Debian Etch system. MySecureShell is an SFTP server that is based on OpenSSH and can be configured in many ways, e.g. it has support for chrooting users into their homedirs or for limiting upload-/download bandwidths. MySecureShell makes SFTP available for users that do not have shell access so that these users do not have to use the insecure FTP protocol anymore.

Today's Linux screen capture technology

Post date: April 12, 2005, 18:04 Category: Miscellaneous Views: 2475 Comments
Tutorial quote: "I'd like you to help me find out about video screen captures," said one of my editors a while back. "Sure, let me see what's available," I replied. He pointed me to a couple of Web sites to get me started, and here I am a few weeks later ready to share my findings. I'll discuss ways that you can make video clips in Linux, talk about their applications and shortcomings. I'll also cover suitable ways to view your masterpieces once they're recorded.

Video screen captures are useful for jobs like application training, computer instruction, or product demos. An example would be the little one-minute video I set up for my wife. She kept forgetting how to start up Mozilla Mail on her Windows 98 machine. I captured the mouse clicks and screen changes (in real time) as I ran through the process, saving it to a Macromedia Flash file. I then created a little Web page on one of my Apache servers, that described how to start Mozilla Mail and included a link to the Flash file. Instead of asking me how to do it, she can now just click on the video tutorial.

By creating a secure tunnel to your MySQL server using Putty, you can grant localhost access to powerful applications like MySQL Administrator while at the same time, make your server appear as if it isn't even there. In effect, make your MySQL server disappear from the outside world.

Graphical Scripting with Kommander

Post date: April 13, 2005, 02:04 Category: Programming Views: 3005 Comments
Tutorial quote: Kommander is a simplified and modified version of Qt Designer which lets you add scripting abilities to the dialogues it makes. It saves the result as a designer UI file which can be run with Kommander Executer. It is the easiest way to make simple programmes, I like to think of it as graphical shell scripting.

Konstuct is a program to download and install KDE from sources. This tutorial takes us through using Kommander to make a graphical program to configure and run Konstruct.

Post date: June 22, 2005, 09:06 Category: System Views: 3438 Comments
Tutorial quote: Working with SUSE Linux Enterprise Server (SLES) requires an understanding of the login process, including local account files, system accounts, and managing identities.

Using a console shell or the graphical environment are two possible methods of working on a SLES machine.

Finding your way around a SLES installation requires an in-depth knowledge of the filesystem layout. Essential filesystem components are documented and explained in this chapter. Basic filesystem permissions are also described.
