Samba, mdadm, Nagios, and One-Time URLs

by chromatic
Linux Newsletter for 12/09/2002

Welcome to another edition of the O'Reilly newsletter. Whether you have snow on the ground or are expecting pleasant summer sunshine, we're continuing to publish a diverse mix of articles every week. Let's get started.

As nice as it would be to have a homogenous network, most of us live in a messier world. Free software has a way of forcing interoperability, though, and that's why the Samba project is so important. Dustin Puryear's Samba Pushes the Boundaries Again describes new features in 2.2 and anticipated features in 3.0. (Short tease--want to replace an Active Directory server?)

Daniel Solin's starting to get a reputation for simple-yet-clever hacks. In Generating One-Time URLs with PHP, he outlines a scheme to protect sensitive download materials. With a little creativity, it's easier than you'd expect to do clever things.

And Derek Vadala, author of "Managing RAID with Linux," takes a look at the new mdadm (multiple devices admin) package, a simple, yet robust way to manage software arrays. In mdadm: A New Tool For Linux Software RAID Management, Derek covers installation and mdadm's five major modes of operation.

The secret to good system administration is automation. Like the hapless Sorceror's Apprentice, though, you can't always trust your minions to do the right thing. That's why network monitoring is so important. Thankfully, AEleen Frisch (of Essential System Administration, 3rd Edition) returns this week with Top Five Open Source Packages for System Administrators: Nagios, describing the highly useful network-monitoring package. Now you can sleep soundly!

Finally but importantly, Noel Davis provides another Security Alert. This time, there's a reason to upgrade Samba and Pine.

This week also had several interesting Weblogs, including Derek Vadala's thoughts on Red Hat 8.0, Steve Mallet on Microsoft's Lawyers Scaring Red Hat, and Tim O'Reilly on Apple, O'Reilly, and Branding.

That was this week. Watch for Subversion, Linux 2.6, Falcon's Eye, and a year-end retrospective in the near future.

Until next time,

O'Reilly Network and Linux DevCenter Top Five Articles Last Week

  1. Cryptosystems: Configuring SSH
    Cryptosystems are handy, but they're not for everyone right out of the box. In her second article on SSH, Dru Lavigne explores some of the more common configuration options for clients and servers.

  2. Linux Multithreading Advances
    Linux multithreading has traditionally lacked full POSIX compatibility. Recent development kernels have seen the addition of two competing thread replacements. Jerry Cooperstein examines the history and implementation of both NPTL and NGPT in plain English.

  3. Samba Pushes the Boundaries Again
    With version 2.2 stable and well-deployed version Samba 3.0 just around the corner, the Samba team has been very busy. In this article, Dustin Puryear explores some of the new and surprising features in recent builds.

  4. Internationalization and Localization with PHP
    Making your Web sites multilingual doesn't have to mean driving yourself crazy. Adam Trachtenberg, coauthor of the PHP Cookbook, demonstrates how to deliver translated text and images simply and easily.

  5. Top Five Open Source Packages for System Administrators
    AEleen Frisch, author of the recently released Essential System Administration, 3rd Edition, offers the fourth installment in a five-part series on the most useful and widely applicable open source administrative tools. As the countdown continues this week, we've got number two, Nagios.
