Firewall Forensics
http://www.robertgraham.com/pubs/firewall-seen.html
Forensics. The word will forever bring to the surface images of Thomas Naguchi answering questions from Marcia Clark and Jack Klugman as Quincy. By the time a medical forensics expert is called in, it’s usually too late - the victim’s already dead.
But firewall forensics can point a Linux user to potential holes before your […]

GeekLog

http://geeklog.sourceforge.net/
A week or so ago, I sang the praises of Geeklog - a system I’d used on the recommendation of reader Steve Waterman. As I’ve gotten to know this outstanding portal program better over the past few weeks, I’ve become even more a believer.
Geeklog is a full-blown web portal system, written in PHP and intended […]

Kernel Configuration - Part IV
We’re now deep into the second kernel configuration series in Penguin Shell. So far, we’ve talked about finding and acquiring kernel source, either on your machine or via download. We’ve also covered the three methods for configuring the kernel - make config, make menuconfig and make xconfig. Today, we’re going to […]

Intrusion Alerts
I’ve written about Snort in previous Penguin Shell issues. It gets my vote as the best, most easily configured intrusion detector and packet sniffer for Linux. It’s lightweight, eaily configurable and, most importantly, very accurate in its interpretations of network activity. I’d recommend it anyone interested in securing their network connection and understanding what’s […]

I’ve always tried to stay away from hammering the Big Boys in Redmond. But occasionally we need to mention them in a light that’s less than favorable. One of the reasons for doing that is the understanding that, as a newsletter for new Linux users, there are probably quite a few readers who […]

LinuxFocus
http://www.linuxfocus.org/English/
We’ve featured a few items from within LinuxFocus in past issues. It seemed time to feature the entire site. LinuxFocus is a bi-monthly online publication focusing on, well, Linux. The May/June issue contains features on “Trying Out KDE3,” “Replacing a Windows NT/2000 Servier Using Linux and Samba,” “Getting To Know XML,” and much more. These […]

Kernel Configuration - Part III
OK. So you understand the high-level view of the kernel - fundamentally, it’s an interpreter that takes commands from input or processes and passes them on to the hardware, in a way that the hardware can understand. It does much more than that, but let’s leave it at the high level […]

Maxing Handles
Today’s TWEAK is a quick way to set the maximum number of open files on your Linux system. You might think that this would be useful for cutting back on the number of open files. In fact, it’s useful to system administrators running a system with a lot of users. You can, of course, […]

WovenGoods is a German/English site full of Linux apps and information. Using several search engines, WovenGoods can find the information or file you’re looking for. There’s also useful information on servers, distributions, hardware, and news and events. It’s a good one-stop Linux shop with instructions and text both in German and in English.

Kernel Configuration - Part II
Kernel configuration in Linux is not nearly as intimidating as it might seem. It does, however, require a bit of knowledge of your system hardware and a general plan as to how you’re going to use the machine.
The source code for the Linux kernel is located (in most distributions) in /usr/src/linux. […]

Kernel News Flash
http://www.atnf.csiro.au/people/rgooch/linux/docs/kernel-newsflash.html
This is such and informative kernel-related link that I think I’ll let the authors describe it for themselves:

This page is meant to reduce questions to the linux-kernel mailing list of the form “kernel x.y.z doesn’t compile”. Often a fix is posted to the list which solves the problem. Unfortunately, for days afterwards, people […]

Check UPS [340 Kb]

https://sourceforge.net/projects/checkups/
“CheckUPS actively checks United Parcel Service’s Web site (via crontab) on the status of a shipped package. When the package status has changed, it sends notice to any email addresses the user may have supplied (email, ICQ, pager, phone, etc). It provides logging of all status check attempts, results, and the […]

Kernel Configuration - Part I
As promised, we’re starting another series on kernel configuration this week. Today, we’ll take a brief minute or two to take the 10,000-foot view of this code enigma.
The kernel in Linux is the core code of the operating system. In effect, it’s the mediator between your software and your hardware. It […]
