Kickin’ my wireless oldskool, WRT54G-style

Dave Farquhar DD-WRT, Hardware, Servers and Networking , , , ,

I found a couple of old Linksys WRT54G routers and decided to load DD-WRT on them. The first one, an abandoned-by-Linksys WRT54GS model, gave me some trouble, which led me to buying a TP-Link unit to run DD-WRT on. The second unit, which was a vanilla WRT54G, still had firmware available on Linksys’ site, so the upgrade was somewhat straightforward–it went by the book, at least. I installed the latest Linksys firmware, then installed the DD-WRT mini build, then upgraded to the full build.

Linksys WRT54g obsolete
This Linksys WRT54G was one of the best pieces of computer hardware of its day. I can’t recommend it as a router anymore but it can still help you out as an access point.

After getting DD-WRT running on it, I configured it to behave as an access point on channel 6. I was surprised at how strong the signal was. Years ago, I ran a pair of WRT54G routers, and they struggled to cover the house. It’s possible that was due to age, or perhaps I was getting too much interference from my neighbors since we were probably all running our wireless on the default channel in those days because none of us knew better.

As for my WRT54GS, when I tried to upgrade it, I got a nice message stating, “Upgrade are failed!” Nice. Too bad it didn’t add “All your base are belong to us.” That’s when I learned you need to install the last Linksys upgrade first, then upgrade from that. So I downloaded that from some forum, tried flashing that, and received the same message. So I set it aside, figuring I bricked the unit. A few days later, after getting the WRT54G running, I fired up the GS, visited its configuration page, and… found DD-WRT running on it! Upgrade are failed? More like all your upgrade are belong to ME.

In all honesty, I probably got lucky. It’s always best to go by the book on things like this. Including the 30-30-30 reset.

The WRT54G is limited, of course, to 802.11b and 802.11g (54 megabits max) but as a complement to a more modern router, it still has a few tricks left. If you have one laying around, it won’t cost anything aside from about 30 minutes’ worth of effort to load DD-WRT on it and see what it can still do for you.

And if you don’t happen to have one laying around, it’s not hard to find a used WRT54G. I find them at estate sales, garage sales, and rummage sales pretty frequently because a lot of people set them aside when they either buy newer, faster routers or their ISP forces them into an all-in-one unit. Don’t pay too much for it, because it’s aging technology, but I’d say they’re worth grabbing for $5 or less.

Looking back at Sam Posey’s Playing With Trains

Dave Farquhar model railroading, Toy trains , , , ,

I finally got around to reading Playing With Trains (here’s a Nook link), sportscaster Sam Posey’s 2004 memoir of 50 years as a model railroader.

Of course I was mostly interested in the first couple of chapters, where he talks about growing up with Lionel trains. It’s more a personal recollection than a complete history, which was his intent, but that’s good. The history of the consumer perspective often gets lost. He and his mother regarded American Flyer as more realistic but flimsier; Lionel was rugged but ran on unrealistic 3-rail track.

Here’s another interesting tidbit: Growing up in the 1950s, your big toy was either a train set or a fort playset–normal families couldn’t afford both. I was vaguely aware that the fort playsets existed but didn’t know that about them. Read more

More details on the Target hack come to light

Dave Farquhar security , , , , ,

Yesterday I read that the Target malware resided on cash registers (which I’d heard elsewhere before), and that the first step to getting there was via a compromised web server.

And that led to a question in the comments, that sounds like it came from an IT professional:

don’t they have their network segregated into zones!!!? It shouldn’t be possible for a web server to touch a POS system in a store….

The commenter right, it shouldn’t be. But it doesn’t need to be, either. Read more

How to increase the capacity of a Log Logic appliance by 45%

Dave Farquhar security, Software , ,

My 9-5 gig revolves primarily around Tibco LogLogic (I’ll write it as Log Logic going forward, as I write in English, not C++), which is a centralized logging product. The appliances collect logs from a variety of dissimilar systems and present you with a unified, web-based interface to search them. When something goes wrong, having all of the logs in one place is invaluable for figuring it out.

That value comes at a price. I don’t know exactly what these appliances cost, but generally speaking, $100,000 is a good starting point for an estimate. So what if I told you that you could store 45% more data on these expensive appliances, and increase their performance very modestly (2-5 percent) in the process? Read on.

The new trend in monitors

Dave Farquhar Hardware , , ,

Although interest in 4K television is understandably lukewarm at best–high definition only arrived about 15 years ago, the standard it replaced lasted half a century, few people are itching to replace the sets they’ve bought in the last decade when they still work, and there’s precious little 4K content–39-inch 4K televisions are proving to be popular.

But they aren’t going in living rooms. They’re going on desks, connected to computers.

Why the Target data breach news keeps getting worse, and what you need to do

Dave Farquhar security , , , , , , , , ,

As you probably know, last year some still-unknown criminals stole a whole bunch of credit and debit card data from Target. And the story keeps changing. First there weren’t any PINs. Then they got the PINs, but no personally identifiable data. Well, the latest news indicates they got credit card numbers, names, addresses, phone numbers, e-mail addresses, and for a whole lot more people, and probably from a longer length of time than just late November to mid-December.

There are a few things you ought to do if you shop at Target, which many people do. Read more

Allstate electric train sets by Marx for Sears

Allstate electric train sets by Marx for Sears

In the 1950s and 1960s, it was possible to walk into Sears and see Allstate electric train sets on the same shelf as Lionel and American Flyer. These trains are still somewhat common today. That leads to some further questions. For a number of years, Marx made train sets for Sears and put the Allstate brand on them.

In the 1950s and 60s, Sears owned the Allstate insurance company and therefore the Allstate trademark. Sears had Marx put the Allstate brand on train sets that were exclusive to Sears, which they sold alongside Lionel and American Flyer electric trains.
