It would be nice if someone wrote an article on wireless ethernet on Linux
(eg. WaveLAN). I think it would make a good article.
I have installed an LS120 IDE drive in my linux machine and it works
fine. I compiled the kernel with ide-floppy support for this. There
is only one thing missing, a utility that will format floppies in the
LS120 drive. Once I get this I can rip out the 'real' floppy disk
drive and grap it's interrupt for a second lan card. Any Ideas here?
Is the gazette not searchable? I am trying to find out if linux supports
multilink PPP? with the built in pptd or a custom one?

Hi. read your "Getting started with Linux" and as it says it gives a brief
introduction to Linux. I've just started with linux, slakware, and comming from
windows there are some problems that are hard to figure out for yourself. First
of all it's this thing with devices. It took me two hours to get my cd-rom to
work. it's simple, but if you don't know how to mount your cd or you don't know
what a mounted hd/cd etc. is then it's quite tricky. And very often you need
your cd. Then it took me about three more hours to connect to internet. This
was also quite tricky comparing to just use the dial-up networking in windows.
Since much information about linux can be found on the internet it's not good
if you can't connect to it. I don't need this information, but I think these
two things are stuff you should put in your article, espescially how to connect
to an internet provider so you can serch for information on the web. daniel,

I recently attempted to install RedHat Linux 6.0 on a Toshiba Tecra 8000
notebook computer, and ran into a couple of problems. The first time I
installed it, everything appeared to be working properly, except the
keyboard keys were too "touchy". Many times, it would act like the keys
were sticking and print a character twice when it was pressed once.
(I've seen a couple other references to this issue on Usenet, but no
solutions were posted.)
After I used Linux for several days on the notebook, I encountered a
situation where it didn't unlock the hard drive for read/write usage
after it finished performing a disk check with fsck, and subsequent
reboots failed due to the file system being stuck in "read only" mode.
At this point, I decided to reformat and do another install from
scratch. This time around, the only changes I made were #1, not to put
the system in runlevel 5 so it started in X immediately upon boot-up,
and #2, enabled the apmd service for advanced power management. When
this install completed, I had problems right away where Linux would boot
- and then I wouldn't be able to type on the keyboard at all. (Every so
often, I was able to get control of the keyboard back - but only after
multiple reboots by hitting the power button on the notebook.)
Has anyone else out there had any luck running Linux on a Tecra 8000?
Thanks, Tom.
Is it possible to get ISDN adapters to work under Linux though they are =

I have a small home network with 5 systems. I use Linux as my
proxy/firewall/dial-upon demand internet server and fileserver.
Before I upgraded to RH6 I could go to any site on the Web. Now with RH6 I
cannot get to some sites. ie: www.hotmail.com, www.outpost.com and
www.iomega.com to name a few. I can get to them from my Linux box but not
from the network. It sends the request and I see some data return but then
everything stops.
Here is my rc.firewall file:
It looks like those sites don't like how my proxy/firewall is setup. This
only happened when I upgraded to RH6 and the 2.2 series of kernels.
Any Ideas?????????
I have a few old Alpha (UDB Multia) systems. All but one have no disks.
I'm hoping to figure out how to NFS boot one of them to become a diskless
firewall box. I noticed while configuring the kernel that there is an option
for NFS mount of the root, so I suspect all the software pieces are there -
just a small matter of configuring the server to listen for NFS requests. The
primary question I have, is: does anyone know if it is possible (through the
SRM or ARC consoles) to boot directly from the net, or do I have to boot a
floppy first that then boots from the net? I think there's also a way to put
milo into flash memory so I don't need the floppy for milo, but I don't know
how to tell milo to see the ethernet device. If I can't do it directly, how do
I do it indirectly? - it sure would be nice to have one (or more) diskless
alphas. On a somewhat related topic - is there any problem with adding a PCI
NIC card to the Multia to get a second ethernet device for my firewall effort?
Thanks in advance. /egp
Hi, again. I've started saving my photos with a KODAK Picture Disk when I
have them developed. When I was using Windows this was no problem, but now
that I'm using Linux there is. KODAK does not support Linux with the software
that comes with their disks. When I save my images to my HD using MCOPY, the
images are upside down, but not reversed edge-wise. I've tried using gimp to
turn them 'right-side-up', and have managed to do just about everything else
with those images using gimp *but* that. (I fully admit I have no knowledge
about image manipulation, and really only want to know enough to accomplish
this one thing.) Can someone please tell me how to do this with gimp? I'm
using RH 5.1. Thanks in advance for any help you can give me.
I'd like to ask about a strange thing I am getting when I run an SGI
application displayed on a Linux Xserver(PC )
The Linux Xserver is running with RedHat 5.2 as following:
If I open a tiff image (RGB 24bits) on the SGI it shows ok with all colors.
It is also OK if I open the same image on the Linux server using XV or Gimp.
But if I display the image on the linux monitor while it is running on the
SGI the colors are not matching at all. The image resolution is perfect but
for the colors , the white is getting yellowish as if the green channel is
missing or getting dimmer or I can say as the blue and red channel are swapped.
I used with a csh login on sgi:
On linux The fm window appears and I doubleclick on a tiff image:
Today I am asking myself what is wrong and how should I repair. Can
anybody help on this.
Thanks in advance
I have a problem and i hope linuxgazette can help me with it. I'm about
to buy a Toshiba Satellite S4030CDS which comes with the Trident Cyber 9525
video card. I've seen in the Xfree86 3.3.3.1 docs that it supports Trident
cyber 9520. Can i use this driver for the 9525? Please, if you know the answer
or know somebody who can help me let me know.
Thanks very much for reading my message and for the great gazzette!!
I have been using fvwm95 on RH5.2. All the xterms have scrollbars on the
left side of their window. I recently installed SuSE6.1 and found that the
xterm windows in fvwm95 have no vertical scroll bars at all. This makes it
tough to look back through a screen's previous display. I tried the "Scroll
module" in the fvwm95 configuration menue but it scrolls the window itself
rather than the screen display history. I know the previous lines are there
because past display lines appear when I resize the window vertically.
My question is how to I add vertical scroll bars to the xterm displays?
Thanks,
I Have Reacently Installed LINUX on an old 486DX2/66 that I bought for
that specific purpose. I can boot up an login into root but when i issue
the command the command startx to get X to star this is what i get:
Jolt-Freak
I have a problem with hard disk (Seagate 4.3MB). On the start appears
the kernel message:
It appears in all kernel's versions and distributions, which I have
(SuSE 5.3, 6.0, 6.1; RedHat 5.1, 6.0; kernel from 2.0.34 to 2.2.9).
After that I can work in text mode, but in X Window some applications
hang up the system (no key work, no actions, no way to exit or shutdown
the system...).
Help me, please!!!

Hi everyone...
I just got a new PC and it came with Win 98 (and FAT32) pre-installed. I
also recently read an article saying that Linux does not get along with
FAT32. =&gr; LILO can;t be loaded on FAT32. Is this correct ?
I plan on installing Red Hat Linux 6.0 on a seperate slave drive, and
having a dual boot. I need to keep my Win98 as well as everyone in the
family uses it, and likes Games.
Has anyone had any problems with Win98 and Linux ? Is there anything that I
have to watch out for ?
Thanks
By now you would have become the fifth person I have tried to contact
over the above mentioned subject. The closest I got was to a detailed
description on how to partition and install Dos/Win95/OS-2, but when I
tried contacting the person through his e-mail, apparently it no longer
exists. So I am back to square one.
I have purchased REDHAT 6.0 at a local Linux fair. Unfortunately I go
not get them to partition and install it on my computer for free as I
was leaving for China the next day. Now I am trying to do so with great
hardship. The material I have downloaded from Linuz.com and
metalab.unc.edu etc does not serve my needs, so I need your expertise in
detail on how to go about it.
I have formatted my HardDisk 4.5GB. Problem arise when I boot REDHAT 6.0, its an auto generated process
which guides me through. First question: SCSI [select: No/Yes?Back].
When selecting Yes, a selection is provided but on choosing and going to
auto verification, all proposals are rejected because my system has an
Adaptec AVA-1502 SCSI Host Adaptor. I can't go any further!
First, I have gone about the right partitioning?
I can't read the README file on my REDHAT CD Rom because I cannot get it
started.
Please kindly assist me. Thank you.

Hello to all in the linux community, I would like to ask anyone who
might have some idea on how to mount a cdrom in linux, when I go into

Hi! I am a new GNU/Linux user (coming from the OS/2 world). I find the Linux
programs powerful, although it often is quite frustrating to learn to
use all of them.
It's a shame to say, but I write this from a Windoze machine. The reason
is that my cable modem provider (Telia in Sweden) pops out my connection
in 175 seconds when using dhclient under SuSE Linux 6.0. Anyone got a
solution?
Another question I would be very grateful to have an answer to regards
FTP. Which good FTP-programs for X do you recommend? I need one that
supports the PASV (passive) mode. I also would like to have a program
that can sync files between my /home/thomas and my ftp server. I have
heard about "rsync" but don't know anything about it.
Thanks for any help!
At work I have a Linux (Redhat 6.0) workstation and at home I have a

I am a new user to Linux and am running a Compaq Deskpro (for my sins).

I am currently running redhat 4.2 for SPARC on a SPARC IPC. I have been
programming C and C++ for about four years now, but this problem has me
stumped. I am trying to port a few apps over from i386 linux to Sparc
linux. I downloaded the source files and untarred them just fine, but from
then on the horrors begin. I have read the docs for each app and followed
the instructions meticulously, and even tried some of my own homebrewed
fixes to try and get the sources to run, but I still can not get anywhere.
The problems seem to lie in not the source itself, but in the libs
installed on my machine. I get tons of warnings and one error that seems
to stand out. The error is transcribed as something like this:
The only other problem I have found is on perusal of the *.h files, I have
found numerous references to header files in directories that don't EVEN
EXIST!!! Is this a standard thing, or just on the SPARC port for linux?
For example, I am looking inside my /usr/include/sys/time.h and find
references to a linux/time.h, when there is not a linux directory
anywhere!! Is this a standard? If it is, it seems that someone got a
little sloppy in their porting. I have managed to fix this problem by
going in and removing references to files that don't exist or redirecting
them to files that do exist, but the error above has definitely stumped me.
Does anyone have experience with this error and how it can be fixed? I
don't have much experience in building my own header files, but when I did
do it, I never saw that error. I would be much obliged to anyone who could
provide some guidence in this issue.
Spett.le Direttoredel Linux Gazzette,
Mi chiamo Nino Brando, e dato che ho visto in edicola una promozione(se si
può chiamarla così) della red hat di linux, contenente 4 CD.
Vengo al nocciolo, e possibile che ci sia il sistema operativo Linux? Anche
perchè il prezzo non supera le £.25.000, e poi la Red Hat è un sistema
operativo?
Chiedo scusa per la mia ignoranza ma è da poco che vorrei entrare nel mondo
Linux, sarei lieto di una risposta ed anche di qualche consiglio.
La ringrazio,

Hi Linuxsters, I am a current Win98 user trying to switch to Linux, but
I have run into a few little problems!
Firstly, after successfully partitioning my HDD and installing Red Hat
Linux 5.2, I wanted to reinstall Win98 as it was getting rather slow.
So I mounted my (FAT32) C: drive in Linux (mount -t vfat /dev/hda1
/mnt/c:) and backed up my essential files onto the Linux partition.
After reinstalling Windows I copied the files back, only to discover
that some seemed to be corrupted by the Linux filesystem. Some
self-extracting programs like WinZip 7.0 and WinBoost 1.24 will not
execute, giving errors like "Permission denied" or "This is not a Win32
application". This is not a drama as I can simply download these again,
however many of my important compressed "zip" files containing Word
documents are corrupt and some files cannot be extracted. What is the
sitch? Can these files be "fixed"? Should I completely avoid mixing
the two filesystems in future? Any help would be gratefully
appreciated!
Another problem I had was installing StarOffice 5.1 Personal Edition for
Linux - it freezes on page 2 of setup where it asks for the registration
key number. I downloaded the program from download.com and therefore
don't have a number. Even if I did it would be no use as the program
freezes anyway. Also I have since realised that it is probably because
I only have 15MB RAM (1MB for built-in video card) and not the minimum
requirement of 32MB (duh!). Which poses the question, "Why does MS
Office happily run on my system with the flaw-ridden inefficient Windows
OS, while StarOffice won't?" Please excuse me, I am only new to Linux!
I plan to upgrade my RAM soon so hopefully this won't be a problem -
just curious, you know?
I am also having problems getting the appropriate graphics settings
happening on Linux. I have a Socket 7 M571 motherboard with a built-in
64-bit VGA chip. It is a 1 to 4MB chip and I have set it to 1MB (in
BIOS) due to my pathetic RAM situation. In Windows I can easily go to
800x600 and 1024x768 with 16- and 24-bit colour. During Red Hat Linux
5.2 installation I selected "VGA16" video card and "Custom:
Non-interlaced SVGA; 800x600@60Hz, 640x480@72Hz" monitor type. But it
won't go above 640x480 resolution without going into virtual mode. The
colour settings are also not right. What do I do?
And finally (!) every time I exit "X", I get an error message "FreeFont
count is 2; should be 1; Fixing..." What does this mean and how do I fix
it? (do I need to?)
I love the idea of leaving Windows behind but I can't while I have these
problems! Could I ask that any responses be reasonably basic as I am
totally new to Linux (or should I say "Linux is totally new to me!").
All help will be greatly appreciated! Thank you...
Zubin.
I would thank for your good job, i installed red hat linux 5.1 without much

Hi,
I am growing to like the idea, philosophy behind Linux. I am a home user,
reasonable non-technical, is this a good move? and what is the difference
between Redhat and Suse. I hope I'm sending this to the right place and hope
that you'll give me an answer.

I was just reading the article "Setting up mail for a home network using
exim" in issue 42 and I noticed one possible problem. In the suggested .forward
file any mail that contains Emily in the To header will go to emi's mailbox, if
someone was to send a message with several addresses in the To field one to
jbloggs and one address had Emily in it (weather Emily be the Emily on the
local network or some other Emily). If a person sent mail with only one To
address and bcc'd or cc'd the rest that problem wouldn't exist but alas not all
email is sent that way (at least to me). You could probably cut down on the
possibility of this a bit by having it look for Emily's first and last name.
Regards,
I was most impressed with the following article in Linux Gazette 42,
June 1999: "Setting up mail for a home network using exim"
I followed Jan's suggestions on a RedHat 5.1 Linux system and it
eventually worked. You may care to note the following comments and
pass them on to the author (as no email address was offered).
I have seen many requests for interfacing MS Internet Mail (???) to
Linux mail facilities on the Linux User Group discussion lists and
this article is most timely.
Thank you for a great magazine.

News from EDUCAUSE: Edupage, 26 May 1999
A federal judge has indicated that he may rule in favor of Sun
Microsystems in the company's copyright battle with Microsoft
, allowing Sun to keep control of its Java programming language. The
ongoing legal battle between Sun and Microsoft arose from concerns that
Microsoft violated its licensing agreement with Sun for use of Java's source
code by altering Java to run more effectively on the Windows operating system.
U.S. District Judge Ronald Whyte wrote that he will most likely rule in favor
of Sun, preventing Microsoft and other companies from changing Java to run
certain software products better than others. Some analysts speculate that the
court loss may not deter Microsoft, but will instead provide the company with
incentive to stop using Java or even to develop an alternative. (Los Angeles
Times 05/26/99)
IBM plans to adjust its AIX operating system to support Linux
applications. This will allow IBM customers to store all of their Web
applications on one server, the company says. IBM's Robert LeBlanc says, "As
more customers move to the Web, they'll need to integrate applications."
Enabling AIX to run Linux will help customers simplify and manage growing
networks, says LeBlanc. IBM's modified version of AIX will be released by the
end of this year, the company says. Analysts say IBM and Sun, which modified
Solaris to support Linux, are ensuring that they will be able to take advantage
of any Linux Web applications that may become popular in the future. In
addition to the AIX changes, IBM plans to ship its DB2 software with Pacific
HiTech's TurboLinux version of Linux. Pacific HiTech will package IBM's
WebSphere software with TurboLinux by the end of 1999, says IBM's Dick
Sullivan. (Bloomberg 05/25/99)

June 3, 1999, Raleigh, NC-- The Linux Professional Institute
(LPI), an industry-wide group developing a professional certification
program for Linux, is pleased to announce the creation of its corporate
sponsorship program and a number of early sponsors. LPI also welcomes the
addition of several new members to its Advisory Council, including IBM,
ExecuTrain and CompUSA.
Two sponsorship plans, for corporations and individuals, have been
introduced to allow anyone to assist the LPI in its goal of creating a
high-quality, vendor-neutral program. LPI aims to deliver its first
certification exams in July 1999.
"While we have heavily depended on the volunteer community in the spirit of
other Linux projects, putting together a respected certification program
requires a substantial investment," said Chuck Mead, LPI Director of
Corporate Relations. "The financial support of the Linux community is
crucial to our program's timeliness and credibility."
The LPI corporate sponsorship program allows for donations from $1,000 to
more than $50,000. Individual sponsorships allow for donations from $100 to
$1,000.
Current sponsors include Caldera, LinuxCare, SuSE, Digital Creations,
Jon 'maddog' Hall, Richard Ames, and others.
A full description of sponsor benefits and other features of the program,
can be found at http://www.lpi.org/sponsorship.html on the LPI website.

Ottawa, Canada -- June 9, 1999 -- Corel Corporation is
pleased to announce that it is joining forces with
Channelware, a business unit of Nortel Networks to rent its
award-winning software applications to customers. This initiative joins the
first program involving distribution of Channelware's NetActive software
through retail stores.
Corel Print House Magic 4 NetActive Version will be available for
customers to rent at select Blockbuster locations in Austin, Texas, and
Anchorage, Alaska, starting in June.
"Channelware invented secure Software Activation and we are proud to be
teaming up with them in this breakthrough initiative," said Dr. Michael
Cowpland, president and chief executive officer of Corel Corporation. "The
dynamics of the computer world are changing rapidly, and we are keen to use
this rental technology to allow our customers to access our products more
easily - even without leaving their houses. This is an innovation in the
software industry."
Channelware's NetActive technology will be embedded in the Corel software,
making it possible for customers to rent the software for 72 hours. Once
the customer brings the CD-ROM home and launches the application, the
software will connect to the Channelware Activation Server. A one-time
InstanceKey is then delivered over the Web in seconds. The key enables the
customer to start using the software. The NetActive system keeps track of
how long the customer uses the software, and offers the customer options
for extended use.
Unlike standard video rentals, the customer will keep the software rental
CD after the initial rental is over. After the rental period, the user has
the option to: rent the software again; buy the right to use the rented
software on a perpetual basis; or buy retail versions of Corel Print House
Magic online and have the shrinkwrap versions of the product delivered to
the door. The 72-hour rental has a suggested retail price (SRP) of US
$5.99; re-renting costs US $3.99. Customers can buy Corel Print House Magic
4 NetActive Version on a perpetual basis for US $29.95*.
GBdirect, Europe's leading provider of Linux training, today announced
the release of free Linux training materials. Lecture notes for the
first four modules of their ``Linux Systems'' training course are now
available on the web (www.linuxtraining.co.uk). The cover:
Each module consists of 20-25 pages of bullet-pointed lecture notes
followed by graduated exercises. Experienced commercial instructors
should be able to deliver the lecture notes in about 1 hour, leaving
between 1 and 2 hours for practical work based on the exercises. In
addition to good teaching skills, the users of these materials are
expected to have sound knowledge of the Linux and UNIX operating
systems.
In the interests of good citizenship, the modules are distributed in
low-bandwidth, open-source, formats.
GBdirect's primary motivation for releasing thse notes as open source
software is to ensure their widest possible dissemination. A
secondary motivation is the company's desire to `give something back'
to the community which provides them with virtually all of their
office software.
The company hope that others will contribute to the Linux Training
Materials Project, by authoring their own lecture notes or by
modifying those which GBdirect have contributed. To encourage such
participation, GBdirect are releasing their materials under an open
source licence derived from the Linux Documentation Project. This
allows end-users to copy and distribute the lecture notes as the
please, but protects the copyrights of their original authors.

Ottawa, Canada- June 15, 1999- Corel Corporation and Rebel.com are hosting
the 1st annual Ottawa Linux Symposium in Ottawa from July 22 to July 24, 1999.
The Ottawa Linux Symposium, run by Achilles Internet Ltd., will provide the
opportunity for Linux developers and system administrators to expand
their knowledge of the Linux operating system. The event is for anyone who
is interested in the technology behind Linux and will feature a number of
prominent speakers from the Linux community. The keynote speaker for the
event is Alan Cox, one of the primary Linux developers. Mr. Cox is the
maintainer for the AC series of leading-edge Linux patches.
Achilles has invited 350 Linux developers from all around the world. The
list of speakers is impressive, including: Pat Beirne of Corel Corporation;
Alex deVries of The Puffin Group Inc.; Zach A. Brown of Red Hat Software Ltd.;
Stephane Eranian of Hewlett-Packard; Miguel de Icaza of GNOME Support; Richard
Guy Briggs of Free S/WAN; and Mike Shaver of Mozilla.org.
Chicago, IL -(June 17 1999) - Neal Nelson, benchmark guru and founder of
the world's largest independent client/server testing facility, has extended an
invitation to Microsoft and Red Hat to participate in an open, public
performance comparison between hot operating system rivals Windows NT and
Linux.
Nelson issued the invitation as a result of a recently published study
sponsored by Microsoft.* One of the conclusions of the study is that
"Microsoft Windows NT Server 4.0 is 2.5 times faster than Linux as a File
Server and 3.7 times faster as a Web Server."
Many have questioned the test results because different tuning levels were
used for NT than those used with Linux. For example, NT was tested with NT
tuning, benchmarking and technical support from Microsoft, as well as
Internet Information Server 4.0 tuning information from the Standard
Performance Evaluation Corp.
Linux however, received almost no additional tuning, support or involvement
from Linux-based technical sources. The testing lab cited difficulty in
obtaining tuning information from Linux knowledge bases, and a query with
Red Hat ended up going through the wrong channels.
This has outraged the growing base of Linux supporters who are clamoring for
an unbiased test, one that is not sponsored by either Microsoft or Linux.

So, my LG activity for this month is pretty sparse. Does
that mean that I haven't been involved in any Linux activity?
Does it mean that I'm not getting enough LG TAG e-mail?
However, my work at Linuxcare
has been taking a pretty big bite
out of my time. In addition the long drive up to the city
(from my house in Campbell to Linuxcare's offices in San Francisco
is about 50 miles) keeps me away from the keyboard for far too
long. (Yes, I'm looking for cheap digs up in the city to keep
my up there during the week).
Mostly I've been working with our training department, presenting
classes on Linux Systems Administration to our customers and our
new employees, and helping develop and refine the courseware around
which the classes are built.
I've also been watching the Linux news on the 'net with my usual
zeal.
The leading story this month seems to be
"Mindcraft III --- The Return of the Benchmarkers."
The results of the benchmarking tests aren't surprising. NT
with IIS still fared better on this particular platform under
these test conditions
than the Linux+Apache+Samba combination. The Linux 2.2.9 kernel and
The Apache 1.3.6 release seems to have closed almost half of the gap.
As I suggested last month, the most interesting lessons from this
story have little to do with the programming and the numeric
results. There were technical issues in the 2.2.5 kernel that
were addressed by 2.2.9. I guess Apache was updated to use the
sendfile() system call. These are relatively minor tweaks.
Microsoft and Mindcraft collaborated for a significant amount
of time to find a set of conditions under which the Linux/Apache/
Samba combination would perform at a disadvantage to NT.
When MS and Mindcraft originally published their results the
suite of tests and the processes employeed were thoroughly
and quickly discredited. I've never seen such in-depth
analysis about the value (or lack thereof) of benchmarking in
the computing industry press.
Nonetheless, the developers of the involved open source packages
shrugged, analyzed the results, did some profiling of their own,
looked over their respective bits of code, devoted hours to
coding tweaks, a few days worth to tests, and spent some time
exchanging and debating different approaches to improving the code.
The important lessons from this are:
This leads us to a broader lesson. We can't properly evaluate any
statistics (benchmark results are statistics, after all) without
considering the source. What were the objectives (the
requirements) of the people involved? Are the objectives of the
people who took the measurements compatible with those of their
audience. In large part any statistic "means" what the presenter
intends it to "mean" (i.e. the number can only be applied to the
situation that was measured).
Benchmarks are employed primarily by two groups of people:
Software and hardware company marketeers, and computer periodical
writers, editors and publishers. Occasionally sysadmins and IT
people use statistics that are similar to benchmarks ---
simulations results --- for their performance tuning and
capacity planning work. Unfortunately these simulations are
often confused with benchmarks.
Jim's first rule of requirements analysis is:
In this case we see two different producers of benchmarks and
a common audience (the potential customers, and the readership
are mostly the same). We also see that the real customers of
most periodicals are the advertisers --- which work for the same
corporations as the marketeers. This leads to a preference for
benchmarks that is bred of familiarity.
Most real people on the street don't "use" benchmarks. They may
be affected by them (as the opinions they form and get form others
are partially swayed by overall reputations of the organizations
that produce the benchmarks and those of the publications they read).
One of the best responses to the Mindcraft III results that I've
read is by Christopher Lansdown. Basically it turns the question around.
Instead of interpreting the top of the graphs as "how fast does
this go?" (a performance question) he looks at the bottom and the
"baseline" system configurations (intended for comparison) and
asks: "What is the most cost effective hardware and software
combination which will provide the optimal capacity?"
This is an objective which matches that of most IT directors,
sysadmins, webmasters and other people in the real world.
Let's consider the hypothetical question: Which is faster, an
ostrich or a penguin? Which is faster UNDERWATER?
What Christopher points out is that a single processor PC
with a couple hundred Mb of RAM and a single fast ethernet
card is adequate for serving simple, static HTML pages to
the web for any organization that has less than about 5 or
6 T1 (high speed) Internet lines. That is regardless of
the demand/load (millions of hits per day) since the webserver
will be idly waiting for the communications channels to clear
whenever the demand exceeds the channel capacity.
The Mindcraft benchmarks clearly demonstrate this fact.
You don't need NT with IIS and a 4 CPU SMP system with a
Gigabyte of RAM and four 100Mbps ethernet cards to provide
web services to the Internet. These results also suggest
rather strongly that you don't need that platform for
serving static HTML to your high speed Intranet.
Of course, the immediate retort is to question the applicability
of these results to dynamic content. The Mindcraft benchmark
design doesn't measure any form of dynamic content (but the
c't magazine
did - their article also has performance tuning hints for high-end hardware).
Given the obvious objectives of the designers of this benchmark
suite we can speculate that NT wouldn't fare as well in that scenario.
Other empirical and anecdotal evidence supports that hypothesis; most
users who have experience with Linux and NT webservers claim that
the Linux systems "seem" more responsive and more robust;
Microsoft uses about a half dozen separate NT webservers at their
site (which still "feels" slow to many users).
This brings us back to our key lesson. Selection of hardware and
software platforms should be based on requirements analysis.
Benchmarks serve the requirements of the people who produce and
disseminate them. Those requirements are unlikely to match those
of the people who will be ultimately selecting software and
hardware for real world deployment.
It is interesting to ask: "How does NT gain an advantage in this
situation?" and "What could Linux do to perform better under those
circumstances?"
From what I've read there are a few tricks that might help.
Apparently one of the issues in this scenario is the fact that
the system tested as four high speed ethernet cards.
Normally Linux (and other operating systems) are
"interrupt-driven" --- activity on an interface generates an
"interrupt" (a hardware event) which triggers some software
activity (to schedule a handler). This is normally a
efficient model. Most devices (network interfaces, hard disk
controllers, serial ports, keyboards, etc) only need to be
"serviced" occasionally (at rates that are glacial by
comparison to modern processors).
Apparently NT has some sort of option to disable interrupts on (at
least some) interfaces.
The other common model for handling I/O is called "polling." In
this case the CPU checks for new data as frequently as its
processing load allows. Polling is incredibly inefficient under
most circumstances.
However, under the conditions present in the Mindcraft survey
it can be more efficient and offer less latency than interrupt
driven techniques.
It would be sheer idiocy for Linux to adopt a straight polling
strategy for it's networking interfaces. However, it might be
possible to have a hybrid. If the interrupt frequency on a
given device exceeds one threshold the kernel might then switch
to polling on that device. When the polling shows that the
activity on that device as dropped back below another threshold it
might be able to switch back to interrupt-driven mode.
I don't know if this is feasible. I don't even know if it's
being considered by any Linux kernel developers. It might
involve some significant retooling of each of the ethernet
drivers. But, it is an interesting question. Other interesting
questions: Will this be of benefit to any significant number of
real world applications? Do those benefits outweigh the costs
of implementation (larger more complex kernels, more opportunities
for bugs, etc)?
Another obvious criticism of the whole Mindcraft scenario is the
use of Apache. The Apache team's priorities relate to correctness
(conformance to published standards), portability (the Apache
web server and related tools run on almost all forms of UNIX, not
just Linux; they even run on NT and its ilk), and features
(support for the many modules and forms of dynamic content, etc).
Note that performance isn't in the top three on this list.
Apache isn't the only web server available for Linux. It also
isn't the "vendor preferred" web server (whatever that would
mean!) So the primary justification for using it in these
benchmarks is that it is the dominant web server in the Linux
market. In fact Apache is the dominant web server on the Internet
as a whole. Over half of all publicly accessible web servers
run Apache or some derivative. (We might be tempted to draw a
conclusion from this. It might be that some features are more
important to more web masters than sheer performance speeds and
latencies. Of course that might be an erroneous conclusion ---
the dominance of Apache could be due to other factors. The
dominance of MS Windows is primarily and artifact of the PC
purchasing process --- MS Windows comes pre-installed, as did
MS-DOS before it).
So, what if we switch out Apache for some other web server.
Zeus (http://www.zeustech.net/products/zeus3/), a commercial
offering for Linux and other forms of UNIX, is probably the
fastest in existence.
thttpd (http://www.acme.com/software/thttpd/) is probably the
fastest in the "free" world. It's about as fast as the
experimental kHTTPd
(an implementation of a web server that
runs directly in the kernel -- like the kNFSd that's available
for Linux 2.2.x).
Under many conditions thttpd (and probably kHTTPd) are a few
times faster than Apache. So they might beat NT + IIS by
about 100 to 200 per cent. Of course, performance analysis is
not that simple. If the kernel really is tied up in interrupt
processing for a major portion of it's time in the Mindcraft
scenario --- then the fast lightweight web server might offer
only marginal improvement FOR THAT TEST.
For us back in the real world the implication is clear, however.
If all you want to do is serve static pages with as little load
and delay as possible --- consider using a lightweight httpd.
Also back in the real world we get back to other questions.
How much does the hardware for a Mindcraft configuration cost?
How much would it cost for a normal corporation to
purchase/license the NT+IIS configuration that would be required
for that configuration? (If I recall correctly, Microsoft still
charges user licensing fees based on the desired capacity of
concurrent IIS processes/threads/connections. I don't know the
details, but I get the impression that you'd have to add a few
grand to the $900 copy of NT server to legally support a
"Mindcraft" configuration).
It's likely that a different test --- one whose objectives were
stated to more closely simulate a "real world" market might
give much different results.
Consider this:
The whole test could be redone for $5000 and $10000 price points
to give an overview of the scalability of each configuration.
Note that this proposed benchmark idea (it's not a complete
specification) doesn't generate a simple number. The graphs of
the entire performance are the result. This allows the potential
customer to gauge the configurations against their anticipated
requirements.
How would a team of Linux/Apache and Samba enthusiasts approach
this sort of contest? I'll save that question for next month.
Meanwhile, if you're enough of a glutton for my writing (an
odd form of PUNishment I'll admit) and my paltry selection of
answers, rants and ramblings for this month isn't enough then
take a look at a couple of my "Open Letters"

Thanks Dennis.
I do have questions regarding this part:
From phax on Mon, 31 May 1999
Would the terminal program start the null modem connection or
would you have to have it be connected before hand through DOS
(I don't know a whole lot about DOS)? I know Linux will be
looking for a terminal on ttyS0 but will a terminal emulator
show up as a terminal connected on that port?
Sorry to be such a nag,

This refers to Upgrade breaks
several programs... in Issue 42. From Peter Caffall on Mon, 31 May 1999
Jim:
Thanks you for your detailed reply. Since I wrote, I resolved
(although not yet solved) the problem. I had a free partition on
my disk, which I made bootable, and installed (from scratch) the
new RedHat 5.2. This came up with no real problems. Then I began
moving some of the stuff from the old partition to the
new. Everything works. When things settle down, and I've got
everything from the old slice that I need, I will just wipe it
out, and free it up.
The reference to libc.so.5.4.33 was due to a reference on another
page to problems with Netscape.
Thanks again
From Tim Baverstock on Fri, 25 Jun 1999
Hi.
I came across this page where someone'd asked you a question,
apparently identical to something a (non-techie) friend of mine is
now experiencing, except that his Linux is a vanilla RedHat 5.1
install (although with Star Office, and RedHat 5.2 Ghostscript and
ppp).
He has a PCI PnP soundcard in his machine, which he's not managed
to get working with W95 or with Linux, but the rest of the machine
worked fine for both OSs, including the floppy.
All of a sudden, about a month ago, the floppy stopped mounting on
Linux (works fine on W95).
Nothing appears in /var/log/messages.
During shutdown, the umount -a line in
/etc/rc.d/init.d/halt hangs too.
If you're interested in whether fiddling with the soundcard fixes
the problem, I'll be happy to let you know, but since mcopy and
mdir work, this seems unlikely.
Nothing's been added or removed within the machine's case, so I
think the only thing that could have changed, which persists over
powerdowns, is the CMOS, and hence (presumably) some aspect of PnP
that W95 was fiddling around with.
I've only ever had isapnp work under RedHat 6.0, when Redhat did
it all for me!
Cheers,
From Tim Baverstock on Sun, 27 Jun 1999
Hi Jim.
Ach! Rats!
I forgot to email you the solution I discovered!
The drive wrote perfectly well under Windows, and worked without difficulty in
both directions with mcopy. I should have made this clearer in my
first email; my apologies for this.
The functionality of the drive, and the evident integrity of the msdos filing
system module eliminated those subsystems from the problem, which was why I was
so perplexed, and why I wrote to you.
The next day, I used strace on `mount' to try and find out
where it hung. It hung on the actual mount() system call itself.
I noticed that the automounter was in `D' discwait on the process
list during its own mount attempt, so I disabled it in the boot sequence
while trying to find out what was going on (I wanted to strace the very
first attempt to mount the floppydrive) but that cured the problem!
Further investigation (with strace) revealed that I'd earlier changed
/etc/resolv.conf to include a domain search path while trying to set
my friend up with an ISP account, and the DNS hang was causing automount to
hang while trying to finagle those strange pseudo-NFS mounts of the local
host it does (by the host's internet name, not as `localhost') for the floppy
drive!
I fixed resolv.conf, and the problem went away, although I've left
AMD disabled, because autofs does the same job, and was installed alongside
it on RedHat; and because one day I'll get my friend's ISP working on Linux
as well as Windows. I don't want this to repeat.
Many thanks for your response, and my apologies once more for not writing
sooner,
Tim Baverstock.

Hello my name is Bernie.
I have a 16 year old son that is heading for big trouble on
the net while I am at work. I can not be in both places at
the some time to keep an eye on him. Do you know if there are
any programs that will run in Windows 98 that can copy the
key board buffer to a file that would let me read in a text
format. I would like the program to run at boot up and be
able to copy the buffer all day long. I believe reading his
keyboard buffer may be of some help to me.
Please help, thank you for any help you my have to offer,

Greetings from Jim Dennis
HARDLY!
That "ostrich" approach is more commonly found in
corporate and government circles than among freeware
programmers. This is largely due to management. A
development manager at a large corporation will tend
to put as much energy into internal PR and "spin
control" as to any real improvement in the product.
Programmers often find themselves at odds with
their own management.
It would be easy to focus on "beating the Mindcraft
benchmark" --- to insert special case code that exists
solely to produce superior results under the specific
conditions present in that suite of tests.
This is referred to as "fraud."
It would be technically easy for the kernel developers
to write the code for this. However, it would be
difficult to actually perpetrate this or any other fraud
in any open source project (since the code is there for
all to see --- and there are a number of people who
actually read that code).
So, the Linux, Apache, and Samba developers showed
admirable focus on real improvements and seemed to
have eschewed any temptation to commit fraud.
(We can't know whether the competition has rigged their
platform, since it is closed source and hasn't been
thoroughly audited by reputable independents).
Identify the involved parties.
Objective: Build/configure a web service out of standard
commercially/freely available hardware and software components
such that the total cost of the installation/deployment would be
cost a typical customer less than $3000 outlay and no more than
$1000 per year of recurring expenses (not counting bandwidth and
ISP charges).
Participants will be free to bring any software and hardware that
conforms to these requirements and to perform any tuning or
optimizations they wish before and between scheduled executions
of the test suite.
Results: The competing configurations will be tested with a
mixture various sorts of common requests. The required responses
will include static and dynamic pages which will be checked for
correctness against a published baseline. Configurations
generating more than X errors will be disqualified. Response
times will be measured and graphed over a range of simulated
loads. Any service failures will be noted on the graph where they
occur. The graphs for each configuration will be computed based
on the averages over Y runs through the test suite.
The graphs will be published as the final results.
Hey answer guy!!!>> mount $NEWFS /mnt/tmp
(Mounting my new FS)
>> cp -pax $OLDDIR /mnt/tmp
(Copying all data to /mnt/tmp)
>> umount /mnt/tmp
(unmounting /mnt/tmp? Where does my data go?)
Your data stays both in $OLDDIR and on the filesystem that
you had mounted on /mnt/tmp and which you'll be mounting
over a new (empty) mount point which has the same name
as the directory that contains the original copy of your data).
See the next couple of commands:
>> mv $OLDDIR $OLDDIR.old
(Moving directories)
>> mkdir $OLDDIR
(recreating directory)
>> chmod $OLD_DIR_PERMS $OLDDIR
(Setting perms)
>> mount $NEWFS $OLDDIR
(Mounting new FS)
Using these commands you now have two copies of your
data. One copy is named .../$OLDDIR.old and the other
is a new filesystem mounted on .../$OLDDIR
After you've verified, to your satisfaction, that
everything is alright after your change, you can remove
the old copy with 'rm -fr $OLDDIR.old'
In general there are two ways to transparently migrate
data from one filesystem to another under UNIX.
The method I've describe moves the data onto a new
filesystem that's mounted directly under the old
location. Another method is to create a new filesystem
on an arbitrary mount point (conventionally /u1, /u2, etc).
and the original directory is replaced with a symlink to
point to a directory under that new fs.
In either case it's possible that some differences will
not be entirely transparent. In particular some files
might have had hardlinks that crossed the boundary of the
directory tree. Those links would now be broken (resulting
in two separate files where formerly you had one file
with two or more links. This is rarely a problem. However
you could test for this case with a bit of scripting and editing.
Mainly you generate a report using 'find'. Use something like:
find $FSROOT -xdev -not -type d -links +1 \
-printf "%i %p\n" | sort -n
... where $FSROOT is the root of whichever filesystem
houses the directory tree that you're trying to migrate.
This prints a list of files sorted by their inodes. Any set
of hard links to a given file have their device number and
inode pair in common. You can then manually seach the
resulting list (usually fairly short). For any even file
you don't have to worry at all if all of its links, or none
of its links, are under the subdirectory tree that you are
moving. Probably there will be none that have this problem.
For those that do, simply replace one set of the hard links
with symlinks. In other words, all of the hard links that
are inside the target directory tree should be converted to
symlinks, or vice versa.
It's very unlikely that this will cause any problem. If you
ever see a case where a UNIX or Linux program suffers from
"transplant shock" I'd like to hear about it.
Where is the old data that needs to go back into the newly
created $OLDDIR?
You copied it with the 'cp -pax'
Null Modems: Connecting MS-DOS to Linux as a Serial Terminal
Linux will look for terminal connections on
a line (/dev/ttyS0, /dev/ttyS1, whatever) if it
it has a "getty" process running on that port.
You set up a getty process by modifying your /etc/inittab
and adding a line like:
d1:23:respawn:/sbin/agetty -L 38400,19200,9600,2400,1200 ttyS1 vt100
... where you can use agetty, uugetty, mgetty, or
getty_ps (but not mingetty). The syntax and additional
configuration of each of these other getty packages differs slightly.
Search through old issues of the Answer Guy for more
detailed explanations and examples.
[ Issues 16, 17, 18, 21, 22, and 23 mention getty, and more
recently, issues 34 and 37 describe using X over serial lines.
-- Heather ]
As far as the DOS side of this, you generally just have to
start up your terminal emulation package and configure it
for "direct" or "null-modem" use.
Upgrade Breaks Several Programs, /proc Problems, BogoMIPS Discrepancies
A visit to "Library Hell"
Pete Caffall
Glad you got it working.
If you have the disk space (on a second drive or extra
partition) you could do a fresh installation of
Red Hat 6.0 and then selectively
migrate your configuration and data files from your old filesystems.
It's sort of a slow laborious way to do upgrades, but it's one that works
for me.
Floppy Failure: mdir Works; mount Fails
Does writing to the floppy work under MS Windows?
I can `less -f /dev/fd0', to see the data on the floppy, and
mdir/mcopy work fine.
Does 'mcopy' work in both directions (copying to
the floppy as well as from it)?
The machine mounts his W95 C: drive as /mnt/dosC, and
that works perfectly as well.
So we know that this kernel is compiled with
FAT fs support (linked in directly or the
loadable module support is working).
When I try `mount -t msdos /dev/fd0 /tmp/floppy', the mount
command goes into `D' wait in the `ps axf' output, as
does the update demon. The floppy lights, spins, then stops, but no
failure messages appear, and I can't kill the mount. Subsequent
attepts to mount also block, and if I recall correctly, mcopy says
it can't write to the device.
For my earlier kernels, I used the cmgr patch.

What happens if you try mounting it in read-only mode?
It sure sounds like a hardware failure. I'd buy an
extra floppy drive (about $20 US in most computer parts
stores). I've asked questions to see if the problem
is limited to the write functionality (since a careful
reading of your messages seems to correlate to read-only
vs. read/write access). When you mount a filesystem
in rw mode under Linux --- I think the atime on the
root of that filesystem will be updated (involving
a write to the media). If it works when you try the
'mount -o ro' variation on the command --- that
suggests that it is related to the write functions.
Found The Culprit!
Incompetance in Parenting
Bernie in Los Angeles
First, I'm NOT the "I want to spy on my children's use of MS
Windows" Guy! I'm the Linux Gazette Answer Guy.
Of course, if you used Linux it would be pretty easy to
secure the system so that the Internet and the modem were
inaccessible during specific times of day or until specific
passwords had been typed. It would even be possible to
configure filtering and access control (to monitor and limit
web access). You'd probably need to invest in some
cabinetry (physically securing a PC generally involves carpentry).
Your question has nothing to do with Linux.
More importantly your problem is much larger than any
software can solve. No software in the world could possibly
make your son more trustworthy. You cannot keep your kid
out of "big trouble on the net" by spying on his keystrokes.
If the muddled thinking that leads you to the fundamentally
flawed (and morally corrupt) notion that you should covertly
spy on your own teenage child using such software is typical
of your approach to parenting then its probably too late for
Bernie Jr.
I don't know what kind of "big trouble" you're trying to
protect the kid from. If it's porn, keep in mind that porn
sites are generally accessed through a GUI browser --- which
are conveniently configured for one-handed operation (point
and shoot, so to speak). If you're afraid that the kid is
"cracking" (sometimes erroneously referred to as "hacking")
and/or phreaking than any attempts you make to lock him out
of your Windows '98 PC will just be too pathetic. If you do
successfully find out that he's been vising 'badboys.net'
what do you plan to do? Confront him with your printouts?
Ground him until he's 35?
So what do you think the kid will do when he knows he's been
caught out? Will it be an contest: your computer skills and
time against his? Can he detect and bypass your futre
methods better than you can implement them? Will he go use
some buddy's computer? Will he skip the virtual trouble of
the 'net and go out to get into trouble of a more dangerous
variety? What will it do for the kid's opinion of you that
you don't have the balls to talk to him directly and that
you have to resort sneaking around on him?
The whole think is disgusting.
If you can't trust the kid with the computer by himself ---
lock the computer is some room when you're not home or get
rid of it.
Try Linux ... and Grammar
Sounds like a bad drive, bad cable, or bad controller
(not to mention a bad keyboard actuator).
It could be some incompatibility between the slave and
master (some IDE drives cannot co-exist in some combinations
on an IDE channel). Try running it on the other IDE channel
that you'll find in most recent PCs. (Configure the new
drive as standalone or as the master to your IDE/ATAPI
CD-ROM if you have one on that channel). Make sure to try a
fresh drive cable.
You might also try using some punctuation and capitalization
in your messages. This is not IRC. When you ask volunteers
(such as me) to provide the technical support that your
vendor was supposed to have sold you, the least you can do
is spend a little extra time on your message. It's best if
you can give the impression that you've done a bit of
research and made some attempt to find the answer on your
own.
Naturally you could also try installing Linux on this drive.
Linux has a neat utility called 'badblocks' which can be
used by itself and which is called by our filesystem
creation and filesystem check utilities (mke2fs and e2fsck
among others). After all, I'm the LINUX GAZETTE "Answer Guy"
not the "my Samsung IDE hard drive doesn't work with
Microsoft Windows '95 rev B answer guy."
Out of Space....or Inodes? All Sparsity Lost?
You might not have preserved allocation "holes" (the
"sparsity") of the files as you transferred them.
When a program opens a file in write mode and does a seek()
or lseek() to some point that is more than a block past the
end of the file, the Linux native filesystems (ext2, minix,
etc) will leave the unnecessary blocks unallocated. This
is possible in inode based filesystems (not in FAT/MS-DOS
formatted filesystems).
These filesystems treat reads into such unallocated regions
of a file as blocks of NULs (ASCII zero characters).
So, you use normal read and write commands in sequence
(like 'cp' and 'cat' to to copy files) then you'll expand
any such "holes" in the allocation map (the inode's list
of clusters) into blocks of NULs and the file will
take more space than it used to.
One possibility is that you used to have such "sparse"
files and that your method of copying them failed to
preserve those "holes." You could use the GNU 'cp
--sparse=always' option to restore the "holes" in
selected files (or create new ones wherever there are
blocks of NULs in the data).
Most files are not sparse --- in fact there are only a
couple of old dbm style libraries that used to create
them in normal system use (the sendmail newaliases
command used to be a prime example).
I don't think this accounts for your whole problem (i.e.
it's not wholly a "holey" problem).
Now, the problem is this: after the copy
