Apply your monthly patches just as soon as you can

There are only six patches in this month’s edition of Patch Tuesday, and only one of them is critical, but it’s a big one.

The critical patch fixes a flaw in Remote Desktop Protocol, something typically only present in the business-oriented flavors of Windows. But if you don’t know whether you’re affected, it behooves you to let Windows update whatever it wants to update. Read more

Why Firefox will probably always have mixed acceptance in corporate environments

I saw an article in Information Week today about Firefox in the enterprise.

The fanboys on both sides took offense, of course.

I’m a longtime Firefox user and an IT professional, but yet I agree with the premise that Firefox will always have trouble in that environment.The biggest reason is inside the firewall, in the corporate intranet. Some commenters complained about lazy in-house design, but that’s not the whole story. Many web-based enterprise applications are designed for Internet Explorer and only Internet Explorer. One app that I support takes it a step further, and only works with IE 5.5 or IE 6. That’s going to be a problem when the order comes down to deploy IE 7. The product is discontinued, so at that point we’ll have to either migrate to something else, or have people connect to a terminal server so they can run IE 6.

I have another web-based application I support (but if I ever change jobs I’ll deny ever hearing about it) that works with IE 7, but if and only if an administrator logs on and manually registers some ActiveX controls. That product is called Microsoft Project Server 2003 Web Access.

Yes, you read that right. Even Microsoft can’t properly support its own web browsers.

Any corporate web-based app that uses ActiveX will never run on Firefox. Those that check for a specific IE version might run on a hacked version of Firefox, but if you ever have any problems, you’re on your own. Corporate suits don’t like that.

And since computers and applications tend to live almost forever once they’re deployed, IE’s stranglehold on those environments may not be measured in years. We may be talking a decade, or even more.

I’ll submit the refrigerator-sized VAX systems I walk past nearly every day in the server room as evidence of the longevity of some systems. The computers themselves may not be quite 20 years old, but the applications they’re running are at least that old.

Firefox also tends to go against corporate culture in other ways. One of the first questions a corporate suit will ask is who they can sue if it breaks. Never mind that if a Microsoft product breaks, they probably waived all legal rights as part of the EULA. The guys in corner offices who wear ties know more about that than anyone who works on computers. A wave of the hand makes that problem go away.

Yeah, right. But don’t bother trying to tell them that.

A second problem is that many IT decisions are made, or approved, by people who admire Bill Gates’ wealth. Since Bill Gates became the world’s richest man by selling computer software, his computer software must be the best, period, end of story.

Many of the books decision-makers read perpetuate this belief. One example is the highly popular and influential book Naked Economics by Charles Wheelan. In many circles, this book is a must-read. I have to admit I’m getting as much out of this $11 book than I got out of my college economics class, if not more. But Wheelan trots Gates out again and again as a master visionary, a master programmer, and lots of other things that he clearly isn’t. The examples serve to make Wheelan’s point, which is the most important thing, but they also perpetuate the myth that Bill Gates is the greatest computer scientist and visionary of all time, when the fact is he’s an astute and ruthless businessman who happened to find himself in the computer industry. His track record as a programmer and visionary isn’t all that great.

But because of this myth, spread largely outside of the computer industry proper, many influential people will insist on using the Microsoft product any time there’s a choice. They’re not interested in Wordperfect or Quicken or Dreamweaver or Firefox any other product not made by Microsoft, as long as Microsoft makes something that competes with it.

The Millionaire Mind by Thomas Stanley explains this mentality somewhat. When a person’s job is to make money, they don’t want to do product research and they don’t want to take chances. When they buy tires, a dishwasher, or a refrigerator, they walk into the store and buy the most expensive one, because the most expensive one must be the best. They don’t want to spend time doing market research because they could spend that time making money. And they want something they believe won’t break, because time spent dealing with broken stuff is time they can’t spend making money.

Basically, any time spent discussing or researching a purchase is time that can’t be spent making money. So in the mind of a bean-counter or an executive type, it’s much cheaper in the long run to just choose the Microsoft product and forget about it.

The logic is completely faulty–it’s an excellent example of a red herring logical fallacy, as Bill Gates’ wealth has nothing to do with the quality of his competitors’ products–but arguing that point isn’t likely to get you anywhere. Even if the decision maker is wrong, the time spent arguing about it is probably worth more than the potential savings by going with a different product.

At home, none of this matters. And at home, I’ll keep using Firefox. I’ve been using Firefox since 2002 when it was an obscure project called Phoenix, so I think you can call me a longtime fan.

Firefox made remarkable progress from 2002 to now, while IE has gone from IE 6 to IE 7 in the same timeframe.

But in the corporate world, very little of that matters. Incumbency has its advantages. Some companies will embrace it because of its many advantages. In other companies, users will sneak it in the door, the same way they snuck in PCs in the 1980s and 1990s while the mainframe-centric IT staff wasn’t looking. But in the majority of companies, it’s likely to stay shut out, perhaps because something important requires IE, but if not, the mere absence of Microsoft’s name on the product will be enough to keep it out of some doors.

I don’t expect to ever have Firefox on my PC at my current job. It’s my employer’s loss, but it’s not my decision.

Mac mice, PC data recovery

A two-button Mac mouse!? Frank McPherson asked what I would think of the multibutton/scroll wheel support in Mac OS X. Third-party multibutton mice have been supported via extensions for several years, but not officially from Ye Olde Apple. So what do I think? About stinkin’ time!

I use 3-button mice on my Windows boxes. The middle button double-clicks. Cuts down on clicks. I like it. On Unix, where the middle button brings up menus, I’d prefer a fourth button for double-clicking. Scroll wheels I don’t care about. The page up/down keys have performed that function just fine for 20 years. But some people like them; no harm done.

Data recovery. One of my users had a disk yesterday that wouldn’t read. Scandisk wouldn’t fix it. Norton Utilities 2000 wouldn’t fix it. I called in Norton Utilities 8. Its disktool.exe includes an option to revive a disk, essentially by doing a low-level format in place (presumably it reads the data, formats the cylinder, then writes the data back). That did the trick wonderfully. Run Disktool, then run NDD, then copy the contents to a fresh disk immediately.

So, if you ever run across an old DOS version of the Norton Utilities (version 7 or 8 certainly; earlier versions may be useful too), keep them! It’s something you’ll maybe need once a year. But when you need them, you need them badly. (Or someone you support does, since those in the know never rely on floppies for long-term data storage.) Recent versions of Norton Utilities for Win32 don’t include all of the old command-line utilities.

Hey, who was the genius who decided it was a good idea to cut, copy and paste files from the desktop? One of the nicest people in the world slipped up today copying a file. She hit cut instead of copy, then when she went to paste the file to the destination, she got an error message. Bye-bye file. Cut/copy-paste works fine for small files, but this was a 30-meg PowerPoint presentation. My colleague who supports her department couldn’t get the file back. I ride in on my white horse, Norton Utilities 4.0 for Windows in hand, and run Unerase off the CD. I get the file back, or so it appears. The undeleted copy won’t open. On a hunch, I hit paste. Another copy comes up. PowerPoint chokes on it too.

I tried everything. I ran PC Magazine’s Unfrag on it, which sometimes fixes problematic Office documents. No dice. I downloaded a PowerPoint recovery program. The document crashed the program. Thanks guys. Robyn never did you any harm. Now she’s out a presentation. Not that Microsoft cares, seeing as they already have the money.

I walked away wondering what would have happened if Amiga had won…

And there’s more to life than computers. There’s songwriting. After services tonight, the music director, John Scheusner, walks up and points at me. “Don’t go anywhere.” His girlfriend, Jennifer, in earshot, asks what we’re plotting. “I’m gonna play Dave the song that he wrote. You’re more than welcome to join us.”

Actually, it’s the song John and I wrote. I wrote some lyrics. John rearranged them a little (the way I wrote it, the song was too fast–imagine that, something too fast from someone used to writing punk rock) and wrote music.

I wrote the song hearing it sung like The Cars, (along the lines of “Magic,” if you’re familiar with their work) but what John wrote and played sounded more like Joe Jackson. Jazzy. I thought it was great. Jennfier thought it was really great.

Then John tells me they’re playing it Sunday. They’re what!? That will be WEIRD. And after the service will be weird too, seeing as everybody knows me and nobody’s ever seen me take a lick of interest in worship music before.

I like it now, but the lyrics are nothing special, so I don’t know if I’ll like it in six months. We’ll see. Some people will think it’s the greatest thing there ever was, just because two people they know wrote it. Others will call it a crappy worship song, but hopefully they’ll give us a little credit: At least we’re producing our own crappy worship songs instead of playing someone else’s.

Then John turns to me on the way out. “Hey, you’re a writer. How do we go about copyrighting this thing?” Besides writing “Copyright 2000 by John Scheusner and Dave Farquhar” on every copy, there’s this.  That’s what the Web is for, friends.

~~~~~~~~~~

Note: I post this letter without comment, since it’s a response to a letter I wrote. My stuff is in italics. I’m not sure I totally agree with all of it, but it certainly made me think a lot and I can’t fault the logic.

From: John Klos
Subject: Re: Your letter on Jerry Pournelle’s site

Hello, Dave,

I found both your writeup and this letter interesting. Especially interesting is both your reaction and Jerry’s reaction to my initial letter, which had little to do with my server.To restate my feelings, I was disturbed about Jerry’s column because it sounded so damned unscientific, and I felt that he had a responsibility to do better.
His conclusion sounded like something a salesperson would say, and in fact did sound like things I have heard from salespeople and self-promoted, wannabe geeks. I’ve heard all sorts of tales from people like this, such as the fact that computers get slower with age because the ram wears out…

Mentioning my Amiga was simply meant to point out that not only was I talking about something that bothered me, but I am running systems that “conventional wisdom” would say are underpowered. However, based upon what both you and Jerry have replied, I suppose I should’ve explained more about my Amiga.

I have about 50 users on erika (named after a dear friend). At any one moment, there are anywhere from half a dozen to a dozen people logged on. Now, I don’t claim to know what a Microsoft Terminal Server is, nor what it does, but it sounds something like an ’80s way of Microsoft subverting telnet.

My users actually telnet (technically, they all use ssh; telnet is off), they actually do tons of work is a shell, actually use pine for email and links (a lynx successor) for browsing. I have a number of developers who do most of their development work in any of a number of languages on erika (Perl, C, C++, PHP, Python, even Fortran!).

Most of my users can be separated into two groups: geeks and novices. Novices usually want simple email or want to host their domain with a minimum of fuss; most of them actually welcome the simplicity, speed, and consistency of pine as compared to slow and buggy webmail. Who has used webmail and never typed a long letter only to have an error destroy the entire thing?

The geeks are why sixgirls.org got started. We all
had a need for a place
to call home, as we all have experienced the nomadic life of being a geek
on the Internet with no server of our own. We drifted from ISP to ISP
looking for a place where our Unix was nice, where our sysadmins listened,
and where corporate interests weren’t going to yank stuff out from underneath us at any moment. Over the years, many ISPs have stopped
offering shell access and generally have gotten too big for the comfort of
geeks.

If Jerry were replying to this now, I could see him saying that shells are
old school and that erika is perhaps not much more than a home for  orphans and die-hard Unix fans. I used to think so, too, but the more novice users I add, the more convinced I am that people who have had no shell experience at all prefer the ease, speed, and consistency of the shell
over a web browser type interface. They’re amazed at the speed. They’re
surprised over the ability to instantly interact with others using talk and ytalk.

The point is that this is neither a stopgap nor a dead end; this IS the
future. I read your message to Jerry and it got me thinking a lot. An awful
lot. First on the wisdom of using something other than what Intel calls a server, then on the wisdom of using something other than a Wintel box as a server. I probably wouldn’t shout it from the mountaintops if I were doing it, but I’ve done it myself. As an Amiga veteran (I once published an article in Amazing Computing), I smiled when I saw what you were doing with your A4000. And some people no doubt are very interested in that. I wrote some about that on my Weblogs site (address below if you’re interested).

I am a Unix Systems Administrator, and I’ve set up lots of servers. I made
my decision to run everything on my Amiga based upon several
criteria:
One, x86 hardware is low quality. I stress test all of the servers I
build, and most x86 hardware is flawed in one way or another. Even if
those flaws are so insignificant that they never affect the running of a
server, I cannot help but wonder why my stress testing code will run just
fine on one computer for months and will run fine on another computer for
a week, but then dump a core or stop with an error. But this is quite
commonplace with x86 hardware.

For example, my girlfriend’s IBM brand FreeBSD computer can run the stress testing software indefinitely while she is running the GIMP, Netscape, and all sorts of other things. This is one of the few PCs that never has any problems with this stress testing software. But most of the other servers I set up, from PIIIs, dual processor PIIIs and dual Celerons, to Cyrix 6×86 and MII, end up having a problem with my software after anywhere from a few days to a few weeks. But they all have remarkable uptimes, and none crash for any reason other than human error (like kicking the cord).

However, my Amigas and my PowerMacs can run this software indefinitely.

So although I work with x86 extensively, it’s not my ideal choice. So what
else is there? There’s SPARC, MIPS, m68k, PowerPC, Alpha, StrongARM… pleanty of choices.

I have a few PowerMacs and a dual processor Amiga (68060 and 200 mhz PPC 604e); however, NetBSD for PowerMacs is not yet as mature as I need it to be. For one, there is no port of MIT pthreads, which is required for MySQL. Several of my users depend on MySQL, so until that is fixed, I can’t consider using my PowerMac. Also, because of the need to boot using Open Firmware, I cannot set up my PowerMac to boot unattended. Since my machine is colocated, I would have to be able to run down to the colocation facility if anything ever happened to it. That’s
fine if I’m in the city, but what happens when I’m travelling in Europe?

SPARC is nice, but expensive. If I could afford a nice UltraSPARC, I
would. However, this porject started as a way to have a home for
geeks; coming up with a minimum of $3000 for something I didn’t even plan to charge for wasn’t an option.

Alpha seems too much like PC hardware, but I’d certainly be willing to
give it a try should send me an old Alpha box.

With MIPS, again, the issue is price. I’ve always respected the quality of
SGI hardware, so I’d definitely set one up if one were donated.

StrongARM is decent. I even researched this a bit; I can get an ATX
motherboard from the UK with a 233 mhz StrongARM for about 310 quid. Not too bad.

But short of all of that, I had a nice Amiga 4000 with a 66 mhz 68060, 64
bit ram, and wide ultra SCSI on board. Now what impresses me about this
hardware is that I’ve run it constantly. When I went to New Orleans last
year during the summer, I left it in the apartment, running, while the
temperatures were up around 100 degrees. When I came back, it was
fine. Not a complaint.

That’s the way it’s always been with all of my Amigas. I plug them in,
they run; when I’m done, I turn off the monitor. So when I was considering
what computer to use as a server when I’d be paying for a burstable 10
Mbps colocation, I wanted something that would be stable and consistent.

 Hence Amiga.

One of my users, after reading your letter (and, I guess, Jerry’s),
thought that I should mention the load average of the server; I assume
this is because of the indirectly stated assumption that a 66 mhz 68060 is
just squeaking by. To clarify that, a 66 mhz 68060 is faster per mhz than
any Pentium by a measurable margin when using either optimised code (such as a distributed.net client) or straight compiled code (such as LAME). We get about 25,000 hits a day, for a total of about 200 megs a day, which accounts for one e

ighth of one percent of the CPU time. We run as a Stratum 2 time server for several hundred computers, we run POP and IMAP services, sendmail, and we’re the primary nameserver for perhaps a hundred machines. With a distributed.net client running, our load average hovers arount 1.18, which means that without the dnet client, we’d be idle most of the time.

If that weren’t good enough, NetBSD 1.5 (we’re running 1.4.2) has a much
improved virtual memory system (UVM), improvements and speedups in the TCP stack (and complete IPv6 support), scheduler enhancements, good softdep support in the filesystem (as if two 10k rpm 18 gig IBM wide ultra drives aren’t fast enough), and more.

In other words, things are only going to get better.

The other question you raise (sort of) is why Linux gets so much more
attention than the BSD flavors. I’m still trying to figure that one
out. Part of it is probably due to the existance of Red Hat and
Caldera and others. FreeBSD gets some promotion from Walnut
Creek/BSDi, but one only has to look at the success of Slackware to
see how that compares.

It’s all hype; people love buzz words, and so a cycle begins: people talk
about Linux, companies spring up to provide Linux stuff, and people hear
more and talk more about Linux.

It’s not a bad thing; anything that moves the mainstream away from
Microsoft is good. However, the current trend in Linux is not good. Red
Hat (the company), arguably the biggest force in popularising Linux in the
US, is becoming less and less like Linux and more and more like a software company. They’re releasing unstable release after unstable release with no apologies. Something I said a little while ago, and someone has been using as his quote in his email:
In the Linux world, all of the major distributions have become
companies. How much revenue would Red Hat generate if their product was flawless? How much support would they sell?

I summarise this by saying that it is no longer in their best interest to
have the best product. It appears to be sufficient to have a working
product they can use to “ride the wave” of popularity of Linux.

I used Linux for a long time, but ultimately I was always frustrated with
the (sometimes significant) differences between the distributions, and
sometimes the differences between versions of the same distribution. Why
was it that an Amiga running AmigaDOS was more consistent with Apache and Samba docs than any particular Linux? Where was Linux sticking all of
these config files, and why wasn’t there documentation saying where the
stuff was and why?

When I first started using BSD, I fell in love with its consistency, its
no bull attitude towards ports and packa
ges, and its professional and
clean feel. Needless to say, I don’t do much linux anymore.

It may well be due to the people involved. Linus Torvalds is a
likeable guy, a smart guy, easily identifiable by a largely computer
illiterate press as an anti-Gates. And he looks the part. Bob Young is
loud and flambouyant. Caldera’s the company that sued Microsoft and probably would have won if it hadn’t settled out of court. Richard
Stallman torques a lot of people off, but he’s very good at getting
himself heard, and the GPL seems designed at least in part to attract
attention. The BSD license is more free than the GPL, but while
freedom is one of Stallman’s goals, clearly getting attention for his
movement is another, and in that regard Stallman succeeds much more than the BSD camp. The BSD license may be too free for its own good.

Yes, there aren’t many “figureheads” for BSD; most of the ones I know of
don’t complain about Linux, whereas Linux people often do complain about the BSD folks (the major complaint being the license).

I know Jerry pays more attention to Linux than the BSDs partly because Linux has a bigger audience, but he certainly knows more about Linux than about any other Unix. Very soon after he launched his website, a couple of Linux gurus (most notably Moshe Bar, himself now a Byte columnist) started corresponding with him regularly, and they’ve made Linux a reasonably comfortable place for him, answering his questions and getting him up and going.

So then it should be their responsibility, as Linux advocates, to give
Jerry a slightly more complete story, in my opinion.

As for the rest of the press, most of them pay attention to Linux only because of the aforementioned talking heads. I have a degree in journalism from supposedly the best journalism school in the free world, which gives me some insight into how the press works (or doesn’t, as is usually the case). There are computer journalists who get it, but a g

ood deal of them are writing about computers for no reason in particular, and their previous job and their next job are likely to be writing about something else. In journalism, if three sources corroborate something, you can treat it as fact. Microsoft-sympathetic sources are rampant, wherever you are. The journalist probably has a Mac sympathy since there’s a decent chance that’s what he uses. If he uses a Windows PC, he may or may not realize it. He’s probably heard of Unix, but his chances of having three local Unix-sympathetic sources to use consistently are fairly slim. His chances of having three Unix-sympathetic sources who agree enough for him to treat what they say as fact (especially if one of his Microsofties contradicts it) are probably even more slim.

Which furthers my previous point: Jerry’s Linux friends should be more
complete in their advocacy.

Media often seems to desire to cater to the lowest common denominator, but it is refreshing to see what happens when it doesn’t; I can’t stand US
news on TV, but I’ll willingly watch BBC news, and will often learn more
about US news than if I had watched a US news program.

But I think that part of the problem, which is compounded by the above, is
that there are too many journaists that are writing about computers,
rather than computer people writing about computers.

After all, which is more presumptuous: a journaist who thinks that he/she
can enter the technical world of computing and write authoritatively about
it, or a computer person who attempts to be a part time journalist? I’d
prefer the latter, even if it doesn’t include all of the accoutrements
that come from the writings of a real journalist.

And looking at the movement as a whole, keep in mind that journalists look for stories. Let’s face it: A college student from Finland writing an operating system and giving it away and millions of people thinking it’s better than Windows is a big story. And let’s face it, RMS running
around looking like John the Baptist extolling the virtues of something called Free Software is another really good story, though he’d get a lot more press if he’d talk more candidly about the rest of his life, since that might be the hook that gets the story. Can’t you see this one now?

Yes. Both of those stories would seem much more interesting than, “It’s
been over three years and counting since a remote hole was found in
OpenBSD”, because it’s not sensationalistic, nor is it interesting, nor
can someone explain how you might end up running OpenBSD on your
appliances (well, you might, but the fact that it’s secure means that it’d
be as boring as telling you why your bathtub hasn’t collapsed yet).

Richard Stallman used to keep a bed in his office at the MIT Artificial Intelligence Lab.

He slept there. He used the shower down the hall. He didn’t have a home outside the office. It would have distracted him from his cause: Giving away software.

Stallman founded the Free Software movement in 1983. Regarded by many as the prophet of his movement (and looking the part, thanks to his long, unkempt hair and beard), Stallman is both one of its most highly regarded programmers and perhaps its most outspoken activist, speaking at various functions around the world.

Linux was newsworthy, thanks to the people behind it, way back in 1993 when hardly anyone was using it. Back then, they were the story. Now, they can still be the story, depending on the writer’s approach.

If there are similar stories in the BSD camp, I’m not aware of them. (I can tell you the philosophical differences between OpenBSD,  NetBSD and FreeBSD and I know a little about the BSD directory structure, but that’s where my knowledge runs up against its limits. I’d say I’m more familiar with BSD than the average computer user but that’s not saying much.) But I can tell you my editor would have absolutely eaten this up. After he or she confirmed it wasn’t fiction.

The history is a little dry; the only “juicy” part is where Berkeley had
to deal with a lawsuit from AT&T (or Bell Labs; I’m not doing my research
here) before they could make their source free.

Nowadays, people are interested because a major layer of Mac OS X is BSD, and is taken from the FreeBSD and NetBSD source trees. Therefore, millions of people who otherwise know nothing about BSD or its history will end up running it when Mac OS X Final comes out in January; lots of people already are running Mac OS X Beta, but chances are good that the people who bought the Beta know about the fact that it’s running on BSD.

And it’s certainly arguable that BSD is much more powerful and robust than Windows 2000. So there’s a story for you. Does that answer any of your question?

Yes; I hope I’ve clarified my issues, too.

Neat site! I’ll have to keep up on it.

Thanks,
John Klos

Scanner troubleshooting secrets

~Mail Follows Today’s Post~

Scanner wisdom. One of the things I did last week was set up a Umax scanner on a new iMac DV. The scanner worked perfectly on a Windows 98 PC, but when I connected it to the Mac it developed all sorts of strange diseases–not warming up properly, only scanning 1/3 of the page before timing out, making really loud noises, crashing the system…

I couldn’t resolve it, so I contacted Umax technical support. The tech I spoke with reminded me of a number of scanner tips I’d heard before but had forgotten, and besides that, I rarely if ever see them in the scanner manuals.

  • Plug scanners directly into the wall, not into a power strip. I’ve never heard a good explanation of why scanners are more sensitive to this than any other peripheral, but I’ve seen it work.
  • Plug USB scanners into a powered hub, or better yet, directly into the computer. USB scanners shouldn’t need power from the USB port, since they have their own power source, but this seems to make a difference.
  • Download the newest drivers, especially if you have a young operating system like MacOS 9, Mac OS X, Windows ME, or Windows 2000. It can take a little while for the scanner drivers to completely stabilize. Don’t install off the CD that came with the scanner, because it might be out of date. Get the newest stuff from the manufacturer’s Web site.
  • Uninstall old drivers before installing the new ones. This was the problem that bit me. The new driver didn’t totally overwrite the old one, creating a conflict that made the scanner go goofy.
  • Buy your scanner from a company that has a track record of providing updated drivers. Yes, that probably means you shouldn’t buy the $15 scanner with the $25 mail-in rebate. Yes, that means don’t buy HP. Up until a couple of years ago, getting NT drivers out of HP was like pulling teeth; now HP is charging for Windows 2000 drivers. HP also likes to abandon and then pick back up Mac support on a whim. Terrible track record.

Umax’s track record is pretty darn good. I’ve downloaded NT drivers for some really ancient Umax scanners after replacing old Macs with NT boxes. I once ran into a weird incompatibility with a seven-year-old Umax scanner–it was a B&W G3 with a wide SCSI controller (why, I don’t know) running Mac OS 8.6. Now that I think about it, I think the incompatibility was with the controller card. The scanner was discontinued years ago (before Mac OS 8 came out), so expecting them to provide a fix was way out of line.
m I’ve ever had with a Umax that they didn’t resolve, so when I spec out a scanner at work, Umax is always on my short list.

And here’s something I just found interesting. Maybe I’m the only one. But in reading the mail on Jerry Pournelle’s site, I found this. John Klos, administrator of sixgirls.org, takes Jerry to task for saying a Celeron can’t be a server. He cites his 66 MHz 68060-based Amiga 4000, which apparently acts as a mail and Web server, as proof. Though the most powerful m68k-based machine ever made, its processing power pales next to any Celeron (spare the original cacheless Celeron 266 and 300).

I think the point he was trying to make was that Unix plays by different rules. Indeed, when your server OS isn’t joined at the hip to a GUI and a Web browser and whatever else Gates tosses in on a whim, you can do a lot more work with less. His Amiga would make a lousy terminal server, but for serving up static Web pages and e-mail, there’s absolutely nothing wrong with it. Hosting a bunch of Web sites on an Amiga 4000 just because I could sounds very much like something I’d try myself if I had the hardware available or was willing to pay for the hardware necessary.

But I see Jerry Pournelle’s point as well.

It’s probably not the soundest business practice to advertise that you’re running off a several-year-old sub-100 MHz server, because that makes people nervous. Microsoft’s done a pretty admirable job of pounding everything slower than 350 MHz into obsolescence and the public knows this. And Intel and AMD have done a good job of marketing their high-end CPUs, resulting in people tending to lay blame at the CPU’s feet if it’s anything but a recent Pentium III. And, well, if you’re running off a shiny new IBM Netfinity, it’s very easy to get it fixed, or if need be, to replace it with another identical one. I know where to get true-blue Amiga parts and I even know which ones are interchangeable with PCs, but you might well be surprised to hear you can still get parts and that some are interchangeable.

But I’m sure there are far, far more sub-100 MHz machines out there in mission-critical situations functioning just fine than anyone wants to admit. I know we had many at my previous employer, and we have several at my current job, and it doesn’t make me nervous. The biggest difference is that most of them have nameplates like Sun and DEC and Compaq and IBM on them, rather than Commodore. But then again, Commodore’s reputation aside, it’s been years since I’ve seen a computer as well built as my Amiga 2000. (The last was the IBM PS/2 Model 80, which cost five times as much.) If I could get Amiga network cards for a decent price, you’d better believe I’d be running that computer as a firewall/proxy and other duties as assigned. I could probably get five years’ uninterrupted service from old Amy. Then I’d just replace her memory and get another ten.

The thing that makes me most nervous about John Klos’ situation is the business model’s dependence on him. I have faith in his A4000. I have faith in his ability to fix it if things do go wrong (anyone running NetBSD on an Amiga knows his machine better than the onsite techs who fix NetFinity servers know theirs). But there’s such thing as too much importance. I don’t let Apple certified techs come onsite to fix our Macs anymore at work, because I got tired of them breaking other things while they did warranty work and having to fix three things after they left. I know their machines better than they do. That makes me irreplaceable. A little job security is good. Too much job sercurity is bad, very bad. I’ll be doing the same thing next year and the year after that. It’s good to be able to say, “Call somebody else.” But that’s his problem, not his company’s or his customers’.

Printers aren’t my specialty and I don’t think I’ve ever seen a Canon BJC210, but if your printer has replacable printheads (some printers make the printhead part of the ink cartridge while others make them a separate component), try replacing them. That was the problem with the only Canon printer I’ve ever fixed.
 
You might try another color ink cartridge too; sometimes those go bad even if they still have ink in them.
 
If that fails, Canon does have a tech support page for that printer. I gave it a quick look and it’s a bit sketchy, but maybe it’ll help. If nothing else, there’s an e-mail address for questions. The page is at http://209.85.7.18/techsupport.php3?p=bjc210 (to save you from navigating the entire www.ccsi.canon.com page).
 

I hope that helps.

Subject: Crazy Win98 Networking Computer Problem

Dear Dave:

I am having a crazy computer problem which I am hoping you or your readers
may be able to give me a clue to.  I do have this posted on my daily
journal, but since I get very little traffic, I thought your readership or
yourself may be able to help.  Here’s the problem:

My wife’s computer suddenly and inexplicably became very slow when accessing
web sites and usually when accessing her e-mail.  We access the internet
normally through the LAN I installed at home.  This goes to a Wingate
machine which is connected to the aDSL line allowing shared access to the
internet.

My computer still sends and receives e-mail and accesses the web at full
speed.  Alice’s computer now appears to access the web text at about the
speed of a 9600 baud modem with graphics coming down even more slowly if at
all.  Also, her e-mail (Outlook Express) usually times out when going
through the LAN to the Wingate machine and then out over the internet. 
The LAN is working since she is making a connection out that way.

File transfer via the LAN between my PC and hers goes at full speed.
Something is causing her internet access to slow to a crawl while mine is
unaffected.  Also, it appears to be only part of her internet access.  I can
telnet out from her computer and connect to external servers very fast, as
fast as always.  I know telnet is just simple text, but the connection to
the server is very rapid too while connecting to a server via an http
browser is much much slower and then, once connected, the data flows so slow
it’s crazy.

Also, dial-up and connect to the internet via AOL and then use her mail
client and (external to AOL) browser works fine and is as speedy as you
would expect for a 56K modem.  What gives?

I tried reinstalling windows over the existing set-up (did not do anything)
and finally started over from “bare metal” as some like to say.  Reformat
the C drive.  Reinstall Windows 98, reinstall all the drivers, apps, tweak
the configuration, get it all working correctly.  Guess what?  Same slow
speed via the aDSL LAN connection even though my computer zips out via the
same connection.  Any suggestions?

Sincerely,

Bruce W. Edwards

Hi Bruce,
 
The best thing I can think of is your MTU setting–have you run any of those MTU optimization programs? Those can have precisely the effect you describe at times. Try setting yor MTU back to 1500 and see what that does. While I wholeheartedly recommend them for dialup connections, MTU tweaking and any sort of LAN definitely don’t mix–to the point that I almost regret even mentioning the things in Optimizing Windows.
 
Short of that, I’d suggest ripping out all of your networking protocols and adapters from the Network control panel and add back in TCP/IP and only the other things you absolutely need. This’ll keep Windows from getting confused and trying to use the wrong transport, and eliminate the corrupted TCP/IP possibility. These are remote, but possible. Though your reinstall should have eliminated that possibility…
 
If it’s neither of those things, I’d start to suspect hardware. Make sure you don’t have an interrupt conflict (rare these days, but I just saw one a couple weeks ago so I don’t rule them out). Also try swapping in a different cable or NIC in your wife’s machine. Cables of course go bad more frequently than NICs, though I’ve had horrible luck with cheap NICs. At this point I won’t buy any ethernet NIC other than a Bay Netgear, 3Com or Intel.
 
I hope that helps. Let me know how it goes for you.

Dave

Hi Dave:
 
Thank you for posting on your web site. I thought you would like an update.
 
I verified the MTU setting was still at 1500 (it was).  I have not used one of the optimizing programs on this PC.
 
I removed all the adapters from the PC via the control panel.  Rebooted and only added back TCP/IP on the Ethernet card. 
 
I double checked the interrupts in the control panel, there do not appear to be any conflicts and all devices report proper function.
 
I still need to 100% verify the wiring/hubs.  I think they are O.K. since that PC, using the same adapter, is able to file share with other PCs on the network.  That also implies that the adapter is O.K.
 
I will plug my PC into the same hub and port as my wife’s using the same cable to verify that the network infrastructure is O.K.
 
Then, I’ll removed the adapter and try a different one.
 
Hopefully one of these things will work.
 
Cheers,
 
Bruce

This is a longshot, but… I’m wondering if maybe your DNS settings are off, or if your browser might be set to use a proxy server that doesn’t exist. That’s the only other thing I can think of that can cause sporadic slow access, unless the problem is your Web browser itself. Whichever browser you’re using, have you by any chance tried installing and testing the other one to see if it has the same problems?
 
In my experience, IE 5.5 isn’t exactly the greatest of performers, or when it does perform well, it seems to be by monopolizing CPU time. I’ve gotten much better results with IE 5.0. As for Netscape, I do wish they’d get it right again someday…
 
Thanks for the update. Hopefully we can find an answer.

Dave
