Use Fedora Directory Server For Manageable LDAP

Raise your hand if you've had this conversation with your buzzword-vulnerable boss:

PHB: "We need to move to LDAP."
Long-suffering admin: "For what exactly?"
PHB: "We need to move to LDAP."

So, before we get into exploring the wonders of Fedora Directory Server, let's give that question a meaningful answer. Why should you consider using LDAP?

Microsoft Upset Over Groklaw's Article on ODF

I guess Microsoft is upset that I showed you screenshots that proved that there is no Save As function for ODF in the usual menu in Microsoft Word 2007. If you read Dutch, here's an article attacking Groklaw, with a lot of blah blah blah about it being alpha code and it's not fair and someday it will happen and all that jazz. But there still isn't a Save As option for ODF in that menu. Period. And according to the article, as I read it, there never will be...

Push Windows Printer Drivers with CUPS

  • Enterprise Networking Planet; By Carla Schroder (Posted by tuxchick2 on Jul 22, 2006 11:21 AM EDT)
  • Groups: Linux, Microsoft
Network printing is a leading cause of high blood pressure and premature hair loss in our long-suffering network administrator demographic. Fortunately, the FOSS world, as usual, does its best to mitigate our suffering. Today you shall learn how to use CUPS and Samba together to set up automagic client printer installations. That's right, my hardworking friends, none of this dashing about to individual workstations burdened with driver disks and Windows CDs. The goal here is to never leave your snug underground lair.

Microsoft buys Sysinternals, Winternals

Mark Russinovich is best known lately as the guy who discovered Sony-BMG's rootkit-based copy protection on its music CDs, which the company ultimately abandoned in the face of a withering firestorm of reaction...."I'm very pleased to announce that Microsoft has acquired Winternals Software and Sysinternals."

Another independent bites the dust. It's in Microsoft's interests to roll out the welcome mat to corporate spyware. Now there is one less set of critical eyeballs on the Evil Empire...Carla

Overhauled CUPS: Improved Unix Printing

  • Enterprise Networking Planet; By Carla Schroder (Posted by tuxchick2 on Jul 14, 2006 11:44 AM EDT)
  • Story Type: Reviews; Groups: Linux
CUPS (Common Unix Printing System) version 1.2 was released last month, bursting with over 90 fabulous new features and improvements. Today we'll take a look at them and decide how fabulous they really are. Then for dessert, next week we'll dig into using CUPS as a printer server on mixed Linux/Windows/Macintosh LANs.

The 2006 Linux File Systems Workshop

Why do we need a Linux file systems workshop, when all seems well in Linux file systems land? .... After all, file systems are a solved problem, right? Right?

If computer hardware never changed, we kernel developers would have nothing better to do than argue about the optimal scheduling algorithm and flame each others' coding style. Unfortunately, hardware has this terrible habit of changing frequently, drastically, and worst of all, exponentially. File systems are especially vulnerable to changes in hardware because of their long-lived nature.

When Battling Spam, There Are Few Real Choices

  • Enterprise Networking Planet; By Charlie Schluting (Posted by tuxchick2 on Jul 13, 2006 8:24 PM EDT)
  • Story Type: Tutorial
Recently people have been led to believe that the solution to spam is just around the corner. In the top running, we have SPF, Sender-ID and Domain Keys, but will any of them actually help? The answer is: only slightly. We'll explain why and cover how each of these technologies work.

Bricked! Or, How to Resurrect a Dead Linksys WRT54G

  • Wi-Fi Planet; By Aaron Weiss (Posted by tuxchick2 on Jul 13, 2006 4:04 PM EDT)
  • Story Type: Tutorial
One of the more exciting developments for networking enthusiasts has been the evolution of open-source firmware replacements for certain popular, inexpensive routers (usually the famed Linux-running Linksys WRT54G).

While replacement firmware offers the promise of significantly expanded features, greater customization, and mondo-tweakability, they also carry some risk. Should misfortune strike, you might - oh, let's say, render your router into a useless hunk of plastic. Or, as victims prefer to say, you could "brick it." How does a router become a brick? And if it does, is there any hope of bringing it back to life?

The short answers: "by accident" and "yes...sometimes."

VoIPowering Your Office with Asterisk: Hardware Mysteries Explained

  • VoIP Planet; By Carla Schroder (Posted by tuxchick2 on Jul 11, 2006 10:02 PM EDT)
  • Story Type: Tutorial; Groups: Linux
t's fun and useful to explore pure IP telephony, but most folks want PSTN (Public Switched Telephone Network) integration as well. (PSTN is also known as POTS: Plain Old Telephone Service.) An Asterisk server can interface with "legacy" systems, which means "not IP," or your ordinary old digital and analog telephone systems.

aDesklets: Eye candy for the Linux desktop

Have you ever seen the Mac OS X desktop and wished all that eye candy were available for Linux? Now you can jazz up your Linux desktop with desklets -- nifty little windows that float on your desktop and display information such as weather updates, system monitors, and calenders. Once you have aDesklets installed, you can download and install an assortment of desklets.

Building Network Appliances With Linux, Part 4: Locking Down the Firewall Box

Last time we left off after installing Webmin. Now it's time to configure the two network interfaces, then lock down security. Obviously, a firewall, like any network border device, must be highly secure.

Run Zeroconf for Linux in a Snap

  • Enterprise Networking Planet; By Carla Schroder (Posted by tuxchick2 on Jul 6, 2006 4:35 AM EDT)
  • Story Type: Tutorial; Groups: Linux
The fond dream of computer users everywhere is to plug in their computers and watch as networking automagically sets itself up. Computers are connected and give themselves IP addresses. Network resources are available without having to lift a finger: wireless devices, printers, local Web sites, image galleries, music collections, the boss's greatest inspirational speeches collection, the rude body noise collection — anything that is network-able. Apple users have long been able to do this with Bonjour (formerly Rendezvous). No messy hassles with DHCP, DNS, smbclient, or NIS; no horrid kludges to enable interoperability with cliquish platforms like Windows that hate to share with non-Windows systems.

Networking 101: Understanding iBGP

  • Enterprise Networking Planet; By Charlie Schluting (Posted by tuxchick2 on Jul 6, 2006 2:57 AM EDT)
  • Story Type: Tutorial
Internal BGP is a mechanism to provide more information to your internal routers. Most of last week’s installment on Understanding BGP focused on a stub configuration, where a single router served all the BGP sessions for an autonomous system (AS). This time we’ll delve into the practical use of BGP: iBGP and what it takes to accomplish multihoming.
Charlie's Networking 101 series is excellent

Free Software: Who's Looking Out for You?

  • Enterprise Networking Planet; By Carla Schroder (Posted by tuxchick2 on Jun 29, 2006 6:41 AM EDT)
  • Story Type: Editorial; Groups: Linux
Sometimes I hear my hardworking network and system administrator chums dismissing Free and Open Source Software with "Spare me the philosophy junk. I just want good software, not a sermon." I quite sympathize with the desire to avoid rants and preaches. But I think it's important to understand that the philosophy behind Free Software is why the FOSS ecosystem is so strong and vibrant, and produces such good-quality software, and is so beneficial to end-users and developers.

Worldwide Access to Your Serial Consoles

  • SysAdmin Magazine; By John Fox and Mark Uris (Posted by tuxchick2 on Jun 24, 2006 4:17 PM EDT)
  • Story Type: Tutorial; Groups: Linux
Imagine being able to reboot a server from the system console from Europe or at an airport during a layover. Imagine not having to physically be present at your datacenter to perform tasks that require console access but, instead, doing them in the comfort of your own home or office. Now imagine doing all this with relatively low-cost commodity components running your favorite Unix-variant operating system along with an open source software package.

Ext3 for large filesystems and Time for ext4?

Interesting stuff on the Kernel Development section of LWN last week:

" By storing physical block numbers this way, ext3 can handle 48-bit block numbers - enough to index a 1024 PB device"

"Some developers, most prominently Jeff Garzik, have expressed concerns about merging these changes into ext3; they would rather see a new ext4 filesystem created for new features."

What exactly is the Internet? This article will explain the concepts required to understand BGP, our next Networking 101 topic. Shipping packets around the Internet requires the cooperation of separate organizations, so it isn't as straightforward as learning about an IGP routing mechanism.

ZFS Adds Exciting Twist to Mundane World

  • ServerWatch; By Carla Schroder (Posted by tuxchick2 on Jun 21, 2006 7:12 AM EDT)
  • Story Type: Reviews; Groups: Sun
when OpenSolaris was released it seemed like a nice thing for all those Solaris admins who wanted a shiny new free version to play with, but not so relevant to folks with actual work to do. Zettabyte filesystem, however, changed the landscape.

Officially it's just ZFS now, not Zettabyte. But zettabyte is more fun to say. At any rate, ZFS is very impressive and represents a huge leap past other filesystems on the market. You know, all those filesystem utilities you've been relying on all these years? All that fsck, dump, restore, mkfs, tunefs, and their Ext3/JFS/XFS/ReiserFS/UFS counterparts; volume managers like EVM and LVM; raidtools; rysnc; quota; fdisk, and all the rest of the baggage you've been forced to lug around just to coax filesystems into a semblance of usefulness - using ZFS means you can dump them all. ZFS was written from the ground up to meet modern needs.

DRM, guardrails, and the right to be stupid

  • Free Software Magazine; By Terry Hancock (Posted by tuxchick2 on Jun 16, 2006 1:22 PM EDT)
  • Story Type: Editorial
I think that if people want to jump out of airplanes, down cliffs, or free-climb El Capitan, like Captain Kirk, they should be allowed to do that -- even though it's very clear that they may be stupid things to do that are likely to get them killed. One of the more powerful and hard to refute arguments for Digital Rights/Restrictions Management (DRM), though, is that it can be used in life-critical systems to prevent failures due to users' own modifications -- and it seems to me that this is a sticky case of balancing the right to be stupid with the right to be ignorant.
