Is this Apple a surprise to anyone?

Dave Farquhar Macintosh , , , , , , , ,

So, Apple unveiled its new Imac today. (I’m sick of improper capitalization. We speak English, not C++.) To no one’s surprise, I’m sure, it has a bigger screen. And I’m sure it’s not too surprising that they crammed everything into the unit next to the screen. It’s the next logical step, after the lamp-shaped Imac.

So how’s it gonna do?I think it has potential. Do people really want laptops because they can carry them everywhere they go, or do they want laptops because they can move them about the house freely and don’t have to have a dedicated “computer room”?

I suspect to most people, the latter is more important. Most people have better things to do with their lives than surf the ‘net at Starbucks or Panera Bread.

This new Imac can go on a small desk in a study or spare bedroom and not take over an entire wall the way computers have been doing since the late 1970s. As long as there’s a way to add some memory, and there are ports for people to plug in their digital cameras and their portable MP3 players and a printer, they’ll be happy.

Who knows, maybe demand for wireless printers will increase too.

Some analysts have said they don’t think all-in-one is the slam dunk it was in 1998. I agree it isn’t, but small is a slam dunk. Witness the explosive popularity of cube PCs. Yes, it flopped for Apple, but Apple’s cubes lacked the flexibility, there was too much confusion about their expandability and what exactly they were compatibile with–I designed a Mac network for a client right around the time the Cube was released, but the rumor was it would only work with Apple monitors. That alone killed the deal. They bought G4 towers instead, which would work with NEC and Viewsonic monitors.

But the other problem with the Cube was the price. Yes, it was cheaper than a G4 tower. But the price difference wasn’t enough to make people willing to take a chance on it. And besides, if it was cheapness you wanted, there were at least four companies willing to sell you a PC for half the price of a Cube. Emachines would even sell you a PC for half the price of an Imac.

And that’s the biggest problem I see with this new Imac: price. $1299 gets you in the game. Ten years ago, that was cheap. But this isn’t 1994. Emachines didn’t exist in 1994, and while a Mac would cost you more than a Packard Bell, there wasn’t much price difference between a Mac and a Compaq or an IBM. Compaq or IBM usually had one model that sold for a hundred or two less than the cheapest Apple, and Apple usually wouldn’t give you quite as much CPU speed or quite as much disk space, but if you walked into the store with $1500 in your pocket, which was pretty much the selling price of an average PC, you could walk out with a Mac just as easily as you could walk out with something that ran Windows.

What will Dell give you today for $800? 2.8 GHz, 256 MB RAM, 40 GB hard drive, CD burner, printer, 17-inch monitor, and some software.

For the same money, Apple gives you 1.25 GHz, 256 MB RAM, 40 GB HD, CD burner, and a 17-inch display. No printer.

For $1,299, the price of the new Imac, Dell gives you twice the CPU power and twice the memory. Just not as much wow factor.

Yes, I know the Pentium 4 is a horribly inefficient processor but the design does scale surprisingly well, and efficiency alone won’t make up a 1.6 GHz speed deficit. Besides, if you’re willing to spend four figures, you can get an AMD Opteron. Just not from Dell.

Will this Imac sell? Yes. Will it do much to increase Apple’s 2.2 percent market share? I doubt it. The main audience is going to be people with aging CRT-based Imacs who’ve been holding out for something with a G5 in it. They’ll buy it, find it’s a lot faster than their old one and takes up less space. Of course they’ll like it. But it’s still the Amiga problem. The Amiga didn’t take over the market because it it only sold 6 million units. The Amiga was a commercial failure because those 6 million units sold to 1.5 million people.

People will ooh and ah over how little space this new Imac takes and how convenient its wireless keyboards are. But most of them will buy a Dell because it’s faster. Or cheaper. Or both. Maybe they’ll complain about how much less convenient it is, but it’s just as likely they’ll forget about it.

It happened with the first Imac and it happened with the Cube and it happened with the dual G4 and it happened with the G5. Who are we kidding? To some extent, it’s been happening since 1983 when the Lisa came out. People see the machine and it knocks their socks off until they see the price tag. The classes buy it anyway, while the masses figure out how to get by with something cheaper.

History is going to repeat itself one other way too. Somewhere in the Far East, I guarantee you a no-name maker of whitebox PCs is designing a box that puts the brains of the outfit behind the LCD, just like this Imac. Maybe the thought didn’t occur to the designer until this week. Maybe the designer has been working on it for months already.

It will look a lot like this new Imac, only it will have an AMD or Intel processor in it, and it will run Windows. It might be three months before we see it. It might even be six. But it will appear, and it will be priced under $1,000.

It will sell. And within another six months, everyone will be doing it. This new form factor may not come to dominate the market, but it won’t take much for it to outsell this new Imac. A small percentage of 97.8 percent is likely to be a lot bigger than even a large percentage of 2.2 percent. Compared to the new Imac, these clones will look like a runaway success.

And Mac fanatics will be screaming about another Apple innovation stolen by someone else.

VMWare’s P2V is mildly disappointing but can still save the day

Dave Farquhar Software , , , ,

The order came from higher up: Migrate these seven servers to VMWare. That would be easy if you were running Linux, FreeBSD, OS/2, or basically any operating system not made by Microsoft. Give me an OS/2 hard drive out of a 386 with Microchannel, and I can have it booting on a P4 in a matter of minutes and probably have it operational in half an hour.

But Windows ties itself to the hardware too tightly. So you need a $10,000 software package to migrate it. That package is P2V, which stands for "PC to VMWare." I assume.Actually it’s a $2,000 software package with $8,000 worth of training. Whether you need that training, well, that’s another story.

P2V advertises that it’ll take an image of a server, replace all of its hardware drivers with drivers for the hardware VMWare emulates, and off you go.

It does the most critical part of it just fine. It doesn’t matter if the original server was SCSI, IDE, or something nasty like RLL or ESDI–unlikely, but I’ve seen what desperate times sometimes cause to be put into a production server–and it’ll get it booting on VMWare’s emulated LSI Logic SCSI card.

The biggest thing it doesn’t do is migrate your TCP/IP settings to the new network card. If you happen to have an AMD PCNet-based NIC in the server you’re migrating, you’ll have no problems, but the chances of that are slightly better than my chances of finding an 1897 Carlisle & Finch train set at that estate sale on Itaska Street this weekend. More likely, you’ll have a 3Com or an Intel card in your source server.

That may not be a problem for you. But if you’re migrating a web server that’s hosting twelve dozen sites, each with its own IP address, you’ll be stringing together some curses after paying that kind of money.

Worth it? It is in the sense that a telephone saves you thousands of dollars in travel costs, so you could justify paying $600 for it. If you’ve got a fleet of aging NT4 servers and an expensive maintenance contract to match, and it’s over someone’s dead body that the applications they host will go away, you can save that 10 grand in a fiscal year, get those servers moved to newer, better hardware that’s cheaper and easier to maintain, and get them moved in less than a week. It could take you nearly that long to get NT4 running on brand-new hardware. Once.

So, yes, you can justify it to your accounting department.

As far as the time involved, there’s the time it takes to image and re-image the server. That depends on how fast your network is. There’s the time it takes to build a helper VM that P2V runs on. It’ll take you about 5 minutes per server to set up the VMWare instance. If you’ve got new hardware, it’ll only take a few minutes for P2V to run. Then you have to boot the VM, reconfigure anything that needs reconfiguring, boot it again, and repeat until you fix everything that’s broken. Sometimes that’ll be nothing, and sometimes it might be a lot.

I budgeted 4 hours per server. A couple of them took less than an hour. A couple took 8.

Do I wish it were a better product? You bet your boots I do. Was I glad to have it at my disposal this week? You bet that Carlisle & Finch train set I’m not gonna find this weekend I am.

Thanks to P2V, I get to do something fun this weekend instead of building servers.

No surprises in the PC Magazine reliability/service survey

Dave Farquhar Hardware , , , ,

It’s that time of year again. Time for PC Magazine’s annual reliability and service survey. I’ve been reading it for almost half my life, and half a lifetime ago, it really meant something.

Today, the subtitle ought to be “What happens when you outsource.”So what does happen when you outsource? All the PCs are basically the same these days. It makes sense. We’re down to three or four suppliers for almost all of the chips on the motherboard, and everyone, including the big vendors, buy their motherboards from one of a half dozen or so companies now. Some contract manufacturer in the Far East puts them all together and puts some other company’s name on it.

The good news is that if there’s a secret to building good, reliable PCs, it’s really poorly kept. The basic hardware is much more reliable today than a decade ago. Back when I sold computers at retail, I remember a Compaq sales rep complaining bitterly that Intel’s “Intel Inside” campaign was hurting them by making everyone think all computers were the same inside. At the time they weren’t. Compaq’s engineering and rigorous testing didn’t always produce the fastest PCs, but they were always near the top, and it did produce some really reliable stuff.

Would that same philosophy applied to today’s technology yield something better? It’s impossible to know. Compaq PCs are exactly the same as everyone else’s these days. The good news is the hardware is about as problem-free as it was back then. And so is everyone else’s. The only difference is the software the manufacturer loads on them.

You may be surprised, but even the bargain-basement eMachines scored high on reliability ratings. It turns out it’s cheaper to get things right the first time than it is to cut corners on quality and have to accept lots of returns. Their machines were dirt cheap, the company was profitable, and the reliability was good. That’s why Gateway bought them and then turned management of the combined company over to the eMachines management.

Speaking of Gateway, support is almost uniformly lousy across the board. People have always complained to me that the support people don’t know what they’re doing. Now it’s hard to know how much the phone techs know because you can’t understand them.

Someone has got to realize this makes poor business sense and make a change. IBM knows, but IBM doesn’t sell PCs at retail anymore. In the early ’90s, Gateway had tremendous brand loyalty. Their PCs were terrible, but the tech support was friendly and determined. When Dell and others started undercutting Gateway’s prices, they cut costs by decimating their tech support. The result was lousy computers and no help getting the problem fixed. The only thing left to do was to buy eMachines, whose management had walked into a similarly bad situation in 2001 and righted it.

It’s pretty obvious to me that the way to break this logjam of sameness is to offer first-rate technical support. I want to believe that the first company that moves its technical support back to the United States and advertises the fact would even be able to get by with charging a premium price.

In the meantime, you stand to get slightly better support by buying from a retail store rather than over the phone or web, if only because the store will be able to help you with basic questions. The quality of in-store help varies widely, but if you find good help in the store, find out that person’s name and ask for that person if you have to call again. Most people who are really good don’t stay in retail for long–at least one company here in St. Louis scouts the retail stores’ computer help and tries to hire away anyone over the age of 21 or 22 who seems to be any good–but you may get some good help in the meantime. Use the manufacturer’s support as a backup, if the store will let you.

Leave your DIY PCs at home

Dave Farquhar Hardware , , , ,

This is a response to the eWeek editorial Bring DIY Systems to Work. Nice theory. Unfortunately, lab theory and the real world don’t always mesh.

I like building PCs. I built my first PC in early 1994, back when everything was on a separate card and you had to set interrupts and DMA channels using jumpers and DIP switches and in most cases you had to tell the BIOS exactly what size drive was in it–it wouldn’t detect anything for you. I built my main PC at home myself. I built my secondary and tertiary PCs at home myself too. And my girlfriend’s PC, and my mom’s PC, and my sister’s PC.

Get the idea?

Pretentious Pontifications: R. Collins for President

Dave Farquhar General , ,

R. Collins Farquhar IV, Aristocrat and Scientist.

To the directionless American people.

Greeting:

As my most recent endeavor received little appreciation, it is my great delectation to announce my decision to devote my considerable talents to solving the world’s problems.George W. Bush is in the back pocket of large corporations in a time when there are only two corporations, Intel and Microsoft, who are worthy of any trust. John Kerry is in the back pocket of labor unions and other leftist organizations.

Matters such as war and the economy are best left to the aristocracy, and not to amateurs such as these men. And, being an aristocrat, I have adequate means to support myself for eight years, so I can work without the distraction of trying to tread water above the poverty level on a meager $200,000 salary.

Therefore I am running for president.

John Kerry says he will reduce U.S. dependency on foreign oil but he does not say how. This is because this is a popular idea to which he has given no thought. Some political consultant told him this is what the rabble wants to hear. As even a simpleton like my brother David knows, the way one reduces dependency on oil flowing in from countries that hate you is by increasing your dependency on oil flowing in from countries that do not. Alaska has oil. Alaska is not even a foreign country. Venezuela has oil. We already buy oil from Venezuela. We should keep doing that. Russia has oil. We have money. We need oil. Russia needs money.

I will not state the rest of the obvious.

Now let us tackle the difficult matter of war. Being of rich Scottish heritage, and being descended from warriors who nearly succeeded in overthrowing the King of England except for a minor technicality of being betrayed by the French, I know a few things about war. I know more than a few things about winning a war.

I suppose only an aristocrat would notice such things, but it is very appropriate that our troops wear green camouflage, for many of them are not battle-tested. This is part of the reason why we are not winning the wars in Iraq and Afghanistan. It is painfully obvious to my aristocratic eyes that our troops need more seasoning before we send them off to fight in either of those two countries. Therefore, I propose we declare war on France in order to give our troops an opportunity to learn how to fight a war and gain confidence by absolutely trouncing an enemy. This trenchant and sonorous victory would give our troops confidence and rid us of a distraction. While routing the French army would not provide total preparation for facing the much better-trained guerrilla troops in Afghanistan and Iraq, it would certainly give them confidence, and confidence is 90% of everything.

The economy is easy to turn around. The aristocracy needs to spend more of its pin money. And when unemployment increases, the aristocracy needs to take on more manservants.

There remains but one problem, but hear me out, for I am going to turn that problem into a tremendous advantage: My age. The reports are true that I am but 29 years of age, which is well short of the 45-year requirement. However, I am in possession of an evil twin brother, who, incredibly, is also 29 years of age. Our combined age of 58 is well over the legal requirement. The advantage is that my brother, whom some consider more personable than myself, can take to matters that make presidents popular with the populace, such as jogging, drinking coffee at McDonald’s, looking at trains going around Christmas trees, signing books, making appearances at sporting events, dedicating libraries, granting interviews, and other such examples of woolgathering. He obviously will not know what is going on, but that is okay, because it will make this presidency appear peccant and naive, but such are the hallmarks of recent U.S. presidencies. Meanwhile, I can be tending to vade me*censored*presidential affairs, such as having my manservants bathe me, and then I can tend to a grueling 4-hour workday, whose tasks will include turning around the economy, bringing jobs back to the United States, and winning wars.

With an identical twin frolicking about the country acting as an aegis, it will be impossible at all times to know my whereabouts. So my misguided fans who like to give me fan letters soaked in alcohol and set on fire, or give me a 21-gun salute all by themselves, will not only have to get past the Secret Service, they first will have to figure out where I am. The additional Secret Service agents needed to protect two co-presidents will help the economy, offsetting some of the abstruce disadvantages of having such an ignoramus in such a prominent and redoubtable position.

My vice president, of course, will be none other than Jacques Pierre Cousteau Bouilliabaise le Raunche de la Stenche. He will, of course, be my main deipnosophist, and act as a fountain of yeasty jeremiads.

My time has come. My country needs me.

Not only do I appreciate your vote, I deserve it.

Advice for setting up a computer lab

Dave Farquhar Hardware , , , , , ,

Two weekends ago, I headed back up to Bethlehem Lutheran Church to rebuild the computer lab I had set up for them a few years ago. Built on P3-based Compaq Deskpros and Windows 98, it had held up, but was desperately in need of repair.

The vision of this project was to set up a lab in a declining neighborhood, where kids could come to do their homework and adults could come to learn computer skills. The lab is run under adult supervision, and outsiders with teaching and/or training experience come in occasionally to teach computer literacy classes.

Ultimately, I want this project to produce some sysadmins in North St. Louis. Years ago, when this was in the planning stage, I told Pastor John Schmidtke that I wanted to see some Mercedeses and BMWs in that neighborhood, purchased with salaries earned from skills picked up in that lab.

Well, that hasn’t happened yet. But there’s still time. In the meantime, how about if I talk about what I’ve learned from three years of operation?Fancy computers not necessary

These were midrange machines when they were new. The lab cost some $10,000 to build, including materials to renovate the room. A contractor who attends my church renovated the room to my specifications. For what it’s worth, I told him there would be about 10 computers there, and the keyboards needed to sit so that a five-foot person’s elbows would make a right angle while seated. He built an around-the-room desk to hold the computers and bored out a couple of holes at each station for the keyboards.

Back to the computers. Today those computers would be worth about $100 apiece. That’s OK–they’re fine for word processing and e-mail, casual web browsing, and educational games, which was the goal. They were fine then and they’re fine now.

Any business with a philanthropic mindset could duplicate what we did here with a dozen outmoded office computers. A Pentium II with 64 MB of RAM can run Windows 95 or 98 adequately. There’s no point in messing with anything lower than that, since P2s sell for 50 bucks a pop these days. One thing I will say: The quality of the keyboards, mice, and monitors is much more important than the computers themselves. If people are going to be typing, they need decent monitors, a good mouse, and a keyboard that doesn’t feel like oatmeal. So if you’re working with a budget, plan on spending the most on monitors and optical mice.

Adequate power outlets completely necessary

There was only one hardware failure in this lab’s three years. One computer wouldn’t run, no matter what I did. It wouldn’t even power up.

Well, speaking as someone with a decade of professional experience in sales and service of computers, I’m embarrassed to say the computer that failed wasn’t plugged in. It looked like it was plugged in. But with the electrical outlets in a mismash and the cables all over the place, it wasn’t. Why didn’t I try another power cable and discover the problem? I have no excuse.

I suspect someone needed an outlet for something–be it speakers or a hair dryer, you never know–unplugged something at random, then didn’t plug it back in when finished. Worse yet, the business end of the cable ended up in a box under the desk, so everything looked fine. The result was a computer that didn’t run for about two years. I didn’t even find the stray end of the cable until I traced several other cables.

So provide as many outlets as your breaker box can handle. Provide extras. People will bring in other things they want to plug in. Three outlets per seat (computer, monitor, and speakers) is inadequate. To be safe, plan on four.

Create system images

You’ll have to reload the system no matter what you do. Lockdown software can be counted on to break things for the innocent and at best only slow down the people who are going to circumvent it. When the goal is for people to learn how things work, they need to be at least somewhat free to experiment. So make images of a working system with all software installed. Train someone to re-image the system. Then don’t be shy about re-imaging. Do it once a week or any time something goes wrong with a computer. If you can’t afford Norton Ghost or PowerQuest DriveImage, a freeware alternative called Savepart exists. Use it. Come to think of it, use that, and spend the money you’d spend on Ghost or DriveImage on better keyboards or mice.

Use identical hardware

System images don’t save you much trouble if your hardware is all different. Your image probably won’t work. Use systems that are as similar as possible: same motherboard, same video card, same sound card (if not on the motherboard), same network card. Put the cards in the same slots on each machine.

Frequently you can get away with not being that careful, but trust me, you don’t want the one time in a thousand that it matters to come and bite you.

Match your hardware and operating system

Sometimes it’s not possible to use completely identical hardware. In those instances, make sure any dissimilar hardware is recognized by the OS without loading any drivers. For example, this lab has a mix of Netgear and Intel network cards. The Netgear isn’t recognized by Windows but the Intel is. So I made the image for a Netgear, and when the system comes up with an Intel, it handles the situation gracefully.

Do the same thing for the sound cards and video cards.

Don’t ask too much of your systems

Yes, Windows XP will install and boot on a Pentium II with 64 MB of RAM. But there is absolutely no benefit to it. XP wants lots of memory and CPU power, and when it doesn’t get it, it’s a slow pig. Realistically, a P2 with 64 megs ought to be running Windows 98. Don’t even try 2000 or XP unless you have P3s faster than 500 MHz with 256 MB of RAM.

While there are subtle differences between versions, for the most part Windows is Windows. If someone can use Windows 98 and Office 97, it’s easy to adjust to the current versions. Don’t be afraid of running back-level versions.

Get discounted charity/educational software

You don’t have to pay $200 for Windows and $500 for Office to build a computer lab for a charity. I don’t know what charity or educational prices are right now, but it’s a fraction of that. The rule of thumb is this: If you don’t pay sales tax, you don’t have to pay full price for software either.

Most computer stores can get you information on charity pricing. Support your local computer store. You might need it someday. Who knows–the owner may be able to get you a line on some things you need.

And if worse comes to worse, run Linux. That was my original plan, but Pastor Schmidtke wanted to use what local businesses were using. That’s a better plan, but if you can’t afford software, Linux works nicely and is more than adequate for things like word processing and web browsing.

Just do it. That’s about all else I can say. The lab in your head isn’t doing anyone a bit of good. If it’s worth doing, it’s worth doing badly. If you’ve got a vision for this, get what you can to get the lab up and running. You can always come back and add newer or more computers later.

Go get ’em, SCO!

Dave Farquhar Windows , , , , , , , , , ,

I’m sure you’ve read it 4.3 billion other places already, but Microsoft has been granted a patent on double-clicking.

Well, there’s something you probably have only read a few hundred other places. Apple obviously had people double-clicking more than a year before Microsoft did, seeing as Windows 1.0 was released in November 1985 and the first Macintosh shipped in early 1984. Commodore had Amigans double-clicking by the summer of 1985. So did Atari.

Guess who supplied Atari with its operating system, since Jack Tramiel failed to swindle his way into ownership of the Amiga?

Digital Research, that’s who. DR provided Atari with a version of CP/M-68K, with its GEM GUI running on top of it. Atari marketed the bundle as TOS, for Tramiel OS.

Digital Research got crushed by the Microsoft juggernaut a few years later and eventually sold out to Novell. Novell then attempted to compete head-on with Microsoft (buying up its Utah neighbor, WordPerfect, and part of Borland in the process) and failed spectacularly. Smelling a rat–Novell believed Microsoft sabotaged some of its applications so they would not run under DR-DOS–it then pawned the Digital Research portfolio off on Caldera, a Linux company run by former Novell executives. The catch? Caldera had to turn around and sue Microsoft. Which they did, successfully.

A few more years later, The Santa Cruz Operation, a small Unix firm, wanted out. It sold its Unix-on-Intel business, as well as the rights to the old AT&T Unix (purchased from Novell, ironically) to Caldera, who soon changed its name to The SCO Group to reflect this business.

Yes, this is the same SCO who is now on a legal rampage, suing anything that moves.

Now, whether Novell or SCO is the more rightful owner of the double-click “innovation” is arguable. But such matters never seem to matter to SCO. It’s a frivolous lawsuit, but Darl McBride and Co. have made frivolous and baseless lawsuits into an art form.

Go get ’em, Darl.

Dude, that Dell\’s, like, totally bent!

Dave Farquhar Hardware , , , ,

I fought with everything I had to get something else. So did one of my coworkers and my boss. But it was for naught. Late on Thursday afternoon, a pile of Dell servers showed up outside my office.

I did the only sensible thing to do: I ignored them until Friday morning.

I didn’t like how the box was taped. That shouldn’t make much difference. But what I really didn’t like was what happened after I pulled the PowerEdge 1750 out of the box.

It bent.OK, maybe “flex” is a more appropriate word. I’m used to working with HP servers. They have a one-piece chassis. Although their 1U offerings weigh about the same amount as these Dells, when you pick them up, they remain straight.

I think that’s a useful feature for something you want to shove into a rack.

Why, of course I suggested drugs as a possible explanation. I can’t let the obvious joke slip by.

I was happy to see that these servers, unlike the last Dell I worked on, actually use a ServerWorks chipset rather than a cheap Intel desktop chipset. The Intel stuff is cheaper, but then all you’ve really gotten is a Dell Dimension in a rackmount case. In all honesty, I’ve run Linux on Intel and Sis and Via chipsets and turned those systems loose as servers, but when you’re spending money rather than repurposing systems, you should spend the money to do the job right.

I was less happy when I went to install Linux on it. The standard Debian 3.0 wouldn’t see it. It was the first time I’d found a system that Debian 3.0 wouldn’t boot.

A Google search quickly turned up a custom Debian boot CD for Dells, which I used to do the installation. Once installed, we compiled a custom kernel so the system would work right. I used to routinely recommend that. That was before I had 125 servers to stay on top of. These days I’m more inclined to use the standard kernel whenever I can–that way, when a vulnerability shows up, I can just apt-get update and reboot, rather than having to compile a kernel and then reboot.

I’m not in love with HP’s service–that’s a story in and of itself, but the short version is that the last time I used their 4-hour-response-time service, it took a day longer than regular warranty service would have taken–but HP’s servers sure make my life less complicated than Dell’s do.

Easy and secure remote Linux/Unix file transfers with SCP

Dave Farquhar Linux , , , , , , , , , , ,

Sometimes you need to transfer files between Linux boxes, or between a Linux box and some other box, and setting up Samba or some other form of network file system may not be practical (maybe you only need to transfer a couple of files, or maybe it’s just a one-time thing) or possible (maybe there’s a firewall involved).
Well, you should already have SSH installed on your Linux boxes so you can remotely log in and administer them. On Debian, apt-get install ssh sshd. If you’re running distro based on Red Hat or UnitedLinux, you may have a little investigative work to do. (I’d help you, but I haven’t run anything but Debian for 2 or 3 years.)

The cool thing about SSH is that it not only does remote login, but it will also do remote file transfer. And unlike FTP, you don’t have to stumble around with a clumsy interface.

If you want to transfer files from a Windows box, just install PuTTY. I just downloaded the 240K PSCP.EXE file and copied it into my Windows directory. That way I don’t have to mess with paths, and it’s always available. Make sure you’re downloading the right version for your CPU. The Windows NT Alpha version won’t run on your Intel/AMD/VIA CPU. Incidentally, Putty.exe is a very good Telnet/SSH client and a must-have if you’re ever connecting remotely to Unix/Linux machines from Windows.

SSH includes a command called SCP. SCP works almost like the standard Unix CP command. All you to do access a remote file is append a username, followed by the @ sign, and the IP address of the remote server. SCP will then prompt you for a password.

Let’s say I want to move a file from my Linux workstation to my webserver:

scp logo.jpg root@192.168.1.2:/var/www/images

SCP will prompt me for my password. After I enter it, it’ll copy the file, including a nice progress bar and an ETA.

On a Windows machine with PuTTY installed, simply substitute the command pscp for scp.

I can copy the other way too:

scp root@192.168.1.2:/var/www/index.php .

This command will grab a file from my webserver and drop it in the current working directory.

To speed up the transfers, add the -C switch, which turns on compression.

SCP is more secure than any other means of file transfer, it’s probably easier (since you already need SSH anyway), and since it’ll do data compression, it’s probably faster too.

When an AMD system gives you problems, always suspect the power supply

I did some power supply swapping this weekend. My video editing PC had outgrown its 300-watt power supply and I needed something fast, so I bought an Antec 430-watt TruePower box locally. I paid $30 too much, and it’s definitely a show-off box, with gold plating everywhere and multicolored sheathing around the power cables. I don’t care at all about that, but I do care that now my jammed-to-the-gills video editing machine has lots of steady, reliable power. How jammed? It has one PCI slot and one drive bay open. It can suck down some juice.
I then turned my attention to my 1.1 GHz Athlon. I’ve been building it for months. At one point I thought the motherboard was bad because the system always hung after the second reboot during an OS install. Always. I tried different Linux flavors, different Windows flavors, everything. Then the problems continued after I changed the motherboard. Prior to that I’d suspected the memory, but that worked fine in other systems. Then I tried every hard drive I could lay hands on. It didn’t matter how great the drive worked anywhere else, if I tried to run anything but DOS on my AMD, the system wouldn’t let me finish installation.

Once I’d tried a different motherboard, that only left the power supply. My case is an Inwin, with a 250w Powerman power supply installed at the factory. I swapped in my 300W Antec–newly unemployed after being replaced in my video editing box–and the system became stable.

Rule number one, which I’d forgotten, is to always suspect the power supply when dealing with AMD stuff.

In all honesty, I don’t remember when I bought that Inwin case, so I have no idea whether that Powerman was AMD approved or not. But the Antec provides considerably more power on the +3.3v and +5v rails and it works. The Powerman powers old Intel (P2-class) and AMD K6 stuff just fine, but none of my Athlon stuff.

So if you’re cobbling together an Athlon from spare parts and it’s not working, either salvage or buy a decent-quality power supply, preferably one that you know has successfully powered AMD gear in the past. I’ll bet it starts working.
