Today I went to an area hamfest and spent a couple hours wandering around with a friend of mine. Lots of fun stuff to look at, but I was a bit leary about making any big-ticket purchases. (Hamfest purchases are like a box of chocolates... etc....) Was unsuccessful in finding a power supply I needed, but I happened by a table that had all sorts of cheap WiFi gear. While I was tempted to grab one of everything, I settled for getting an old-ish looking Linksys wireless PCI card for a whopping $5. I didn't even check the model number or anything... I just figured that even if it turns out to be a dud, I'm only out a few bucks.Got it home and took a look at it. It appears to be a Linksys WMP11 (11 referring to 11 Mbit/sec, or 802.11b I am assuming). I did some web searching for it to see about getting that model card to run under a non-Windows OS. Most sites referenced a version number for compatibility, as the different versions of the card used different chipsets. This was puzzling, since I was unable to find a version number on the card anywhere. Finally, I found a listing of a number of wireless devices and their chipsets. This list told me that if there is *not* a version number on the card, then it is effectively "Version 1". The neat thing about this, is that the version 1 (or whatever it's called) of this particular card uses a chipset (Prism2) that is linux-friendly, while later versions use less cooperative chipsets.So... I am now going to plug this card into my firewall box and see if I can turn it into an access point.Because... you know... it would be cool. Never mind that I already have one in my house. This way I can have one for guests to use, that isn't attached to my LAN at all (and that I wouldn't have to generate certificates for everyone else to use). I am somewhat tempted to leave it open, but I'll have to see how that goes. At the very least, if I do end up tinkering with my ZyXEL wireless router and brick it, I would still be able to have a wireless network in the house.
Happy to report that the Linksys WMP11 card works perfectly with FreeBSD (and, thus, the pfSense firewall). I did some additional tinkering with the box, and now have the following interfaces:WAN: My DSL connection.LAN: The "normal" home network; this is the network that my RADIUS-enabled WiFi connects to.WiFi: My new access point with the WMP11 card. Currently have it set up as open access, firewalled so that it is Internet only (no connections permitted to other interfaces, and no access to the firewall GUI). pfSense has a "captive portal" option that allows you to force a username/password sign-on via the web before the Internet can be accessed... I may futz around with something like that. Or whatever.DMZ: Normal DMZ interface. Have a laptop running Slackware here that I'm going to make into a web server.XLAN: My own naming convention, for "eXclusive LAN"... or in other words, a LAN with no outbound connections to the Internet or to other interfaces. Toying with the idea of setting up a wargame server or a spare router here and just opening it up for connections from the Internet (for people to play with). For now, there's not even a cable plugged into it... this was more an issue of "Hey, I have a spare ISA slot and a spare ISA network card. Woo."Hm. That's what everybody's home network looks like... right?
Normally, I think those userbars in signatures can be a bit obnoxious. I really don't care who is an American Idol Watcher, or who is a Pot Smoker, or whatever. However, I tinkered a bit, and came up with one that I think I can tolerate: Basically a vanity job, also showing off my new domain: slicktech.net (the first one I've ever had all to myself).Woo.
Just wanted to set up an area where I can put some info on various "projects" I'm either working on, or have ideas for. Here's the short list at the moment:- My home wireless LAN connection currently uses WPA-PSK. I want to set it up so that it uses RADIUS authentication. So far, I've got a more or less working install of FreeRADIUS (actually, two), and am working on tweaking OpenSSL for the certificate stuff (I want to use EAP-TLS, none of this username/password stuff). Links: http://www.wi-fiplanet.com/tutorials/article.php/3557251http://www.linuxjournal.com/article/8095- A couple years ago, I wrote an article for 2600 called "Filesharing using TinyURL.com". In the article, I described a way to convert a file to a text string of bytes, then upload that string to tinyurl.com and get a short link to that string. As a part of this article, I wrote two programs -- "implant" and "extract" -- to automate the process. I began working on an enhanced version of these programs to use a pastebin-type site (pastebin.ca) to allow for bigger files, with options like multithreading and variable file chunk sizes. I kind of stopped working on it, but I've got some new ideas for stuff to implement, and I think it would be cool to keep my Ruby practice up, as well as potentially develop something useful for sneaking files around to different places.No promises to how often this page will get updated, but it's a bit easier than trying to save things in various text files and carrying them with me from computer to computer (I tend to use several different computers in the course of a day).
