  • Server Monitoring With munin And monit

    debian Author: Falko TimmeTags: Comments: 19

    Server Monitoring With munin And monit In this article I will describe how to monitor your server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.

What in the hell is a root kit ??? A root kit is a collection of programs that intruders often install after they have compromised the root account of a system. These programs will help the intruders clean up their tracks, as well as provide access back into the system.

    How To Save Traffic With Apache2's mod_deflate In this tutorial I will describe how to install and configure mod_deflate on an Apache2 web server. mod_deflate allows Apache2 to compress files and deliver them to clients (e.g. browsers) that can handle compressed content which most modern browsers do. With mod_deflate, you can compress HTML, text or XML files to approx. 20 - 30% of their original sizes, thus saving you server traffic and making your modem users happier.

  • Creating A Safe Directory With PAM And EncFS

    Author: stefbonTags: Comments: 5

    Creating A Safe Directory With PAM And EncFS This HowTo is about creating a user-session-safe directory which offers security on- and offline. This is done with PAM, a module named pam_script and EncFS ("Encrypted Filesystem"). This safe directory is used to store credentials and other sensitive information during a session. When a usersession is ended, in the worst case an encrypted directory remains on the harddrive. In the best case everything is removed. This construction is only meant to store information during a session, not for documents or any other valid information.
