Running network services as a non-root user

Post date: April 20, 2006, 10:04 Category: Security Views: 3221 Comments
Tutorial quote: There are many times when it is convenient to allow non-root users to run services, or daemons, which bind to "privileged ports". There are several approaches to this problem each with its own set of pros and cons. Read on for a brief look at the most common approaches.

How to scan your Linux-Distro for Root Kits

Post date: May 19, 2006, 18:05 Category: Security Views: 3223 Comments
Tutorial quote: Do you suspect that you have a compromised system ?
Check now for root kits that the intruder may have installed !!!

So... 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.
Root kits will sometimes leave processes running so that the intruder can come back easily and without the system administrator's knowledge !

Solution....
Scripts like chkrootkit will do the job for you automatically.

System encryption on Debian Etch

Post date: August 16, 2006, 16:08 Category: Security Views: 5041 Comments
Tutorial quote: In this article I will describe how to setup a nearly complete encrypted system using Debian Etch and cryptsetup with LUKS. The goal is: encrypt all partitions except /boot. The user should enter a password at boot time or provide a keyfile on an USB device to decrypt the root partition. Keyfiles for additional partitions are located on the root, so the user does not need to enter a password for every partition.

Mini-Howto for User Mode Linux

Post date: April 12, 2005, 17:04 Category: System Views: 2291 Comments
Tutorial quote: UML ("User Mode Linux") allows you to run multiple Linux servers on one physical machine. This can be handy for many different purposes. For example, you might want to give different people root rights, but prevent them from interfering with one another. Or, you might want to have several identically configured servers, one for production, one for development, and one for testing, but without investing in multiple physical machines.

Once you have prepared your machine for running UML instances as described in the following section, adding new instances will take less than five minutes. The preparation, however, might take a bit longer.

Keep an Eye on Your Linux Systems with Netstat

Post date: April 12, 2005, 17:04 Category: Network Views: 2251 Comments
Tutorial quote: Two of the fundamental aspects of Linux system security and troubleshooting are knowing what services are running, and what connections and services are available. We're all familiar with ps for viewing active services. netstat goes a couple of steps further, and displays all available connections, services, and their status.

Linux virtual server on Debian Sarge

Post date: November 29, 2005, 21:11 Category: System Views: 3375 Comments
Tutorial quote: Linux-VServer allows you to create virtual private servers and security contexts which operate like a normal Linux server, but allow many independent servers to be run simultaneously in one box at full speed. All services, such as ssh, mail, Web, and databases, can be started on such a VPS, without modification, just like on any real server. Each virtual server has its own user account database and root password and doesn't interfere with other virtual servers.

Comprehensive Linux System Services List: Explanation and Recommendation

Post date: December 17, 2007, 06:12 Category: Miscellaneous Views: 3568 Comments
Tutorial quote: Linux services are basically programs that start at boot time to provide certain features and services (Apache, the web server for example). After installation, every Linux distribution provides a list of enabled services. However, you might not need some of these services or you might need others that are not enabled by default. Having only the services you need running will make your system faster, more stable and secure. So the first thing you need to do after installing a Linux distribution is to manually edit the list of enabled services. Unfortunately, some services don’t provide a description, others provide a description that’s not understandable so you might end-up disabling a vital system service just because you didn’t know what it did and you thought you didn’t need it.

Webmin installation and configuration on OpenSuSe

Post date: November 17, 2008, 11:11 Category: Installing Views: 4174 Comments
Tutorial quote: Webmin, developed by Jamie Cameron, acts as a comprehensive interface to the underlying applications on servers, including support for configuring applications like ftp, ssh, mail, Web, databases and more. Differing from other control panels, the core Webmin interface is intended for system administrators with root access to their servers, and includes a user-based package to enable your users (or clients) to access their own domains, email, and more, within a limited scope. Webmin supports running under SSL.
