|Unix Review takes a look at
scripts with a vi theme.
"This month, Yakov Lerner provides two vi-themed scripts. The first, vi+, allows the standard output of Unix commands to be piped into vi. The second, vman, is a wrapper script around the reference manual command, man. vman strips the formatting characters from the man command output, and places the resulting output into a vi buffer."

|chrooted ntpd in NetBSD|
|On Lamp tells us about running
chrooted ntpd under NetBSD.
"ntpd needs superuser privileges for two operations: binding to UDP port 123 (at initialization time) and using time control system calls such as adjtime(2) and ntp_adjtime(2), which are restricted to the superuser. For the first operation, we could proceed as named does, first binding to UDP port 123, then calling chroot(2) and setuid(2). The problem is the second operation. To be able to chroot ntpd after initialization, we need a way to enable an unprivileged user to control the system clock. Such a feature was introduced in NetBSD 1.6, with
the clockctl device."

|New Linux Support Policies are Ominous|
|Security Focus talks about
Red Hat and Mandrake's new support policies.
" know that Red Hat and Mandrake have important reasons to limit support for older operating systems: first, open-source software has an unfortunate tendency to live forever -- many users are still relying on versions of Red Hat even older than 6.2, and supporting these primordial distributions is expensive. The QA and build machines need to be supported, and developers must be diverted from more forward-looking tasks."

|Unix Review takes a look at
"Want to watch a transaction in real time? In addition to capturing network traffic, Ethereal allows you to actually view data while it's being captured. The display window will update in real time (or close to it, anyway) and scroll the packets in the display window as they come in. Another nifty feature of Ethereal is the ability to filter information while capturing it."

"In eWeek Labs' tests, we were particularly pleased with the improvements to KDE's Konqueror Web browser and file manager application, which now includes support for tabbed browsing. Konqueror also stands to improve significantly in future releases, now that Apple Computer Inc. has selected Konqueror's KHTML rendering engine as the foundation for its Safari Web browser."

|Being Hacked is a Lot Like Being Haunted?|
|Jay Beale (from Bastille Linux) answers the questions
"How can I determine if my Linux server has been hacked?
How can I be sure that I haven't been hacked?"
in a new column at Information Security Magazine.
He observes that, "being hacked is a lot like being haunted--odd things
are afoot that you may or may not notice." He talks about Tripwire, but also
discusses how atackers defeat Tripwire with kernel level rootkits. The column
then goes on to talk about how you might detect some rootkits with chkrootkit
or even bypass them entirely. It even discusses detecting backdoors with
NMAP and the impossibility of answering either of these questions with

|Trail of tears: MySQL, ODBC & OpenOffice 1.0|
|Linux World brings us:
Trail of tears: MySQL, ODBC & OpenOffice 1.0.
"This week, I'll describe how I did it on my Red Hat 8.0 desktop machine. McCreesh's how-to was very helpful to me. But there are just enough differences between Red Hat 7.3 (the version upon which he wrote about wiring together OpenOffice and MySQL) and Red Hat 8.0 that I simply couldn't follow it blindly with success. New gotchas appeared to blend in with the old ones. If you're not running RH 8.0, there is a good chance the path I took won't work for you. Perhaps between this article and McCreesh's how-to, you can get it working on your setup."

|Fair Queuing Disk Schedulers|
|Following the recent release of an anticipatory IO scheduler, Andrea Arcangeli started a lengthy thread in which he proposed an SFQ (Stochastic Fair Queuing) disk scheduler. The idea was picked up by Jens Axboe who had evidently worked on a similar idea earlier. Jens quickly posted two different disk schedulers utilizing "fair queuing" algorithms, more commonly used in handling network traffic. When someone suggested he was reinventing the wheel, Jens replied, "There's no wheel reinventing here, just applying the goodies from network scheduling to disk scheduling."

|Mandrake Linux 9.1|
|Distro Watch continues its look at
Mandrake Linux 9.1.
"The beta-testing cycle can get tedious after a while: downloading nearly 2 GB takes some time even with a fast Internet connection, and not everyone has a fast CD-burner (I usually burn my CDs on my 20X Ricoh CD-RW drive, but the machine that I use to download ISO images from the Web only has a painfully slow 2X CD-RW drive). Certainly that's one of the reasons most people end up buying the final distribution CDs or DVDs."
