Your router’s security may not be as secure as you think it is

Thursday, December 29th, 2011

I read a report from Sophos that there is a fairly critical security flaw in many consumer wireless routers. I’ve gone on before about how you should use the strongest encryption method available for your equipment to use (WPA2 if all your stuff can handle it). However, while these routers support that, they also have a feature called WPS (for Wi-Fi Protected Setup) which makes it easy for you to set this up by either pressing a button or entering a PIN on either the device connecting to the network or the router.

Using the PIN method is potentially risky if all you have to do is enter the PIN on your computer or other device. It seems the authentication method for the pin results in a mere 11,000 options remaining which can be brute-forced in less than two days.

When I setup a new router, I’ve always gone for the manual approach and determine a wireless network name (SSID) and key which the clients can remember or have easily available. I don’t even install the software which came with the router but instead go to its web-based administration. I’ll turn off WPS so that it’s not accidentally used (the first and only time I tried using WPS, it scrambled what I’d previously set to something random for both SSID and key).

This falls in line with how security decreases as convenience increases. I advise to disable WPS and do it by hand.

What to do with that old computer

Thursday, June 30th, 2011

You’ve made the decision to replace your computer with a newer, better, faster, cooler computer. What do you do with the old one?

Back in the day when upgrading was option, it was a simple matter to upgrade one component this month and a different component the next. Eventually, you had a new computer, but it was as if nothing changed. This couldn’t be kept up as the industry found better ways of doing things which required new hardware which was not compatible with the old. Basically, it got to the point where to upgrade one thing required a whole new computer around it.

What are your choices for dealing with the old computer? If it’s old enough or abused enough, you may just want to discard it. Check your local dump for details (thankfully my local dump allows e-waste to be dropped off at no charge; they have a specific location at the dump site just for e-waste).

What if it’s not too old? Options include erasing everything on it and reinstalling just as it was when you got it so you could sell it or give it away. The potential problems are two-fold. First, you need to make sure you have another copy of your data and you need to make sure you’ve completely erased everything so the next person doesn’t have access to your personal files. Secondly, do you have the original install discs? On many computers (HP and Compaq in particular, but other brands as well) you hit a particular key on the keyboard when you first power up the computer and it takes you to a special setup routine which can do the erase and reinstall procedure for you (note that the erase done here isn’t a secure one, but should be good enough for most people).

Another common option (and one I’ve done myself a few times) is to repurpose the computer for some other task. How about a central calendar? If your old computer is a Mac, you have one built in. For a PC, you could use Mozilla Thunderbird with the Lightning plugin. Alternatively you could set up a web browser to point to a Google Calendar that you’ve created.

If the computer is small enough, you could put it in your kitchen to run a recipe database. You can run a software title on your computer or, my favorite, just look up recipes on the internet.

Many more options are available to get the most out of your old computer. Experiment with Linux, make a personal file and print server, build your own Digital Video Recorder (DVR). The possibilities are nearly endless.

Should I get a new computer?

Wednesday, June 29th, 2011

I get this question often enough from people who have computers they consider old or slow. The question then becomes where should you put your money?

Many times, the older and slower equipment is fine and just needs a bit of software tweaking. I’ve had amazing performance increases from just changing the anti-malware software that’s on the computer. Some computers, however, need to have everything wiped and reinstalled from scratch to bring them back to their original glory and speed. Part of the problem is finding all the software that was originally installed so it can be put back. Then there’s the time to do it (it typically takes me between two and four hours to backup, erase, and reinstall a computer running Windows, depending upon what needs to be put back when I’m done). This is usually where the money question usually ends up.

Because of how long it takes me to do the job (believe me, I’m not lollygagging around either, I’m just focused on YOUR computer while I do it), if the computer is five years-old, it may be your money is better spent on a new computer instead. New PCs running Windows can be had for $400 or so for something half-way decent. The last couple I customized through Dell were around $700, but had some extras the clients needed as well as some additional software.

What do you do with the old when you’re done? I think I’ll wait until my next blog entry to answer that one. So many possibilities.

More on the Newton

Sunday, January 16th, 2011

I’ve continued looking for things Newton since my previous article and have found some additional resources.

What I really wanted was a flash memory card for mine.  All I need to do is install one or two pieces of software and my Newton is pretty full.  I can’t even recall what I had on it back in the day. I found some information on flash card compatibility at Apple.  I also found a vendor that has some of the original Apple 2MB cards.  And I found another which has some cards which may work (I’m not 100% confident in these).

When looking for the linear flash memory that would work on a Newton, I found that it has some pretty cool features like true random access and faster read times.  Given how ATA flash has improved over the years, these stats may not be as impressive as they used to be.  I’m not sure linear flash has improved similarly over the years.  Not like you’d notice much performance-wise on such an old device.

If you read the comments in yesterday’s post, the author of the My Apple Newton blog posted a link to his archive of software.  I’ve also found links to Newton Connection for Mac OS XDrivers for ATA flash, wireless cards, and others.  I could continue, but the best list for links I’ve found thus far is at the Newton Phoenix site.

I’ll be playing with this “toy” on and off over the next few weeks.  We’ll see what it can still do.

I found my Newton

Thursday, January 13th, 2011

Many many years ago I bought an Apple Newton MessagePad 100.  It was a refurbished unit that was already being replaced by the MessagePad 110.  After many moves and storage units, it got a little lost.  It was found today and I thought I’d give it a whirl.

When I’d last put it away, my recollection was that it didn’t work.  I recall it stopped working the day I replaced the backup battery.  Since one of the accessories I’d bought for it was an AC adapter, I plugged it in and turned it on.  It worked.  I was a little shocked and a little elated, and now I’m wondering what to do with the thing.

It was a great little device in its day.  Years ahead of its time with handwriting recognition (even considering the many jokes about how non-accurate it was).  Consider that it was designed for you to train it.  Later, a company would come out with a piece of software for the Newton called Graffiti which trained YOU instead of the device (Graffiti was later the basis of the Palm Pilot which would supplant the Newton as the dominant PDA).

So, I did some digging to see if I can find software for it.  I still have the PC connection cable (if necessary, I think I can find the Mac serial cable), original protective sleeve, fax/modem, and an extra battery holder.  I also have a charger for the NiCd battery packs which were available, but those had long since become useless and I’d discarded them.

You can get some no longer supported software directly from Apple.  I’ve also found the United Network of Newton Archives repository and the My Apple Newton blog.  I’ve not stopped looking, but I do have more things to seek (like software which definitely works with Windows XP or newer if I can find a machine I still own which has a serial port; none of my Macs certainly have one and I’m not sure I want to buy a USB to serial device).  A linear flash drive would be nice, too, if I can find one of those antiquated things.

Do you have any old hardware lying around that was once cool and might still be?
