From Van: I recently had a need to setup a private directory on my web server that could only be accessed by a handful of selected people. The content also needed to be encrypted in transit. This mini-HOWTO details how I did this on a Red Hat 8.0/Apache 2.0.40 server using mod_ssl and OpenSSL (0.9.6b and higher). Here are the goals of this small project:
 

 Hints in manipulating the DD command, with loads of examples on LinuxQuestions.org. Really nice read for anyone needing to manipulate dd.
 

 In Hacking Linux Exposed, we are able to cover Linux hacking in more detail than ever before. We are able to show you where Linux may differ from other Unix-like systems and give you Linux-specific countermeasures that you can implement immediately. In the hard-hitting style of Hacking Exposed, Hacking Linux Exposed once again dives into the actual attacks used by the enemy. Look no further for the actual exploitation techniques used to surreptitiously gain access to Linux systems.
 

 DROP (Don't Route Or Peer) is an advisory "drop all traffic" list, consisting of stolen 'zombie' netblocks and netblocks controlled entirely by professional spammers. DROP is a tiny sub-set of the SBL designed for use by firewalls and routing equipment.
 

 Since 2001, The Ultimate Linux Newbie Guide has been helping individuals switch to the Linux Operating System. This guide can help both beginners and seasoned computer users alike learn all the important parts of choosing, using and installing Linux, a great free operating system for your computer and help you remove dependency on non-free, closed source software that is commonplace in Microsoft Windows or Mac OS.

In the main chapter by chapter guide, you'll find out why Linux offers a real alternative to other operating systems, how you can install Linux on to your computer for free, and how to get to grips with using Linux on a daily basis without any techno jargon!
 

 A Linuxer writing Howto's and infos on all kind of hardware and distributions. Also - some Hardware based modifications can be seen, and loads of hints viewed. Nice place to seek for infos in case something is missing ...

Note that this is one great site for Mods regarding the NSLU2 - mostly in German though...
 

 dd_rescue is a little tool that helps you when nobody else does: Your harddisk crashed and contains unreadable data. Standard Un*x tools like cp or dd just abort on every error, dd_rescue doesn't.

 It is essentially a collection of tools contained within an organized code structure that is interface-able. These tools are wrapped up in such a way, that the user does not need to know or fully understand the inter-workings of their undertakings; only how to implement them. He/she can install the software and follow on-screen instructions to accomplish ordinarily complex and/or extensive tasks such as starting a web server, monitoring network traffic, or assigning rights and privileges to users for network resources. These tools will not be solely exclusive to the project and will hopefully find their way into others projects as they will find "code leverage" just as useful.
 

 The openssl application that ships with the OpenSSL libraries can perform a wide range of crypto operations. This HOWTO provides some cookbook-style recipes for using it.
 

 All about Linux in this shop. Check it out if you're a FAN.
 

 The table below provides a list of the color names that are supported by all major browsers.

Note: If you want your pages to validate with an HTML or a CSS validator, W3C has listed 16 color names that you can use: aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive, purple, red, silver, teal, white, and yellow. If you want to use other colors, you must specify their RGB or HEX value.
 

 Linux on a modern PC hardware is a very capable router and can achieve the same routing performance as Cisco 72**. But it never gained the same popularity as a router as it did as a server.
One reason is probably administrative: in a big IT department different teams are attending to connectivity and to services. This is natural work division but it has its drawbacks. The networking team would consider Linux routers as a project for the servers team (after all, it is Linux), and the servers team would rightfully think otherwise (it is, after all, networking). Usually both stay polite and mind their own business.
 

 The Community Edition of EnGarde Secure Linux was designed to support features suitable for individuals, students, security enthusiasts, and those wishing to evaluate the level of security and ease of management available in Guardian Digital enterprise products. Its development is very much driven by not only the requests from the community, but also their continued participation.
 

 GNU ddrescue is a data recovery tool. It copies data from one file or block device (hard disc, cdrom, etc) to another, trying hard to rescue data in case of read errors.

Ddrescue does not truncate the output file if not asked to. So, every time you run it on the same output file, it tries to fill in the gaps.
 

 This page consists entirely of links to other pages that I find interesting, helpful or fun. All have proven useful for LINUX install, trouble shooting and learning about LINUX.
