WiFi and Firewall Config

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 c...

More Wireless Debauchery

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.

RADIUS Project Post-Mortem

Before the fresh info in my brain fades into the realm of "that was cool a while ago", I wanted to be sure I posted copies of all the working config files here for the RADIUS/WiFi setup. I will add some commentary where applicable, but this is basically just going to be a laundry list. (If anyone actually reads this and has any questions, I'll be happy to add more descriptiveness.)The Equipment:
  • ZyXEL P-330W Wireless Router (firmware v1.8)
  • Pentium III server: OpenBSD 4.2, FreeRADIUS 1.1.6, OpenSSL 0.9.7j
  • Laptop (WiFi client): Windows XP SP2
  • Laptop (WiFi client): Debian GNU/Linux 4.1 (etch), wpa_supplicant 0.5.5

Quickie... Linux Laptop Now Online

Got it.I poked around the mailing list for wpa_supplicant  for a bit... and while I didn't discover a specific fix for my problem, I did find that you can run wpa_supplicant from the command line with the "-dd" option for extremely verbose output. Dumping the output to a file, I found the following section that sounded kind of familiar to what...

.sig userbar

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:http://img233.imageshack.us/img233/2302/userbar620838fl2.gif  Basically a vanity job, also showing off my new domain...

Linux Foibles

Ironically enough -- since the article I was referencing for my FreeRADIUS / EAP-TLS / WiFi setup was written in Linux Journal magazine -- I've had some difficulty getting my linux laptop connected to the AP. With WPA-PSK (i.e. WPA with a password), it worked fine with the madwifi drivers and the wpa_supplicant  program. However, trying to tweak wpa_s...

It Works. Muahahahaha!

Happy to say that I finally got all the parts of the WiFi RADIUS authentication working on my home network this evening, a little after midnight. As of this writing, my two Windows XP laptops now connect automatically... now I just have to figure out how to set it up on my Debian laptop. (I don't have any of the fancy-schmancy GUI utilities on it, so...

Certificates

RADIUS Project
Okay, I have finally gotten to the point where I'm using OpenSSL to create certificates. As much as I hate to just copy and paste stuff into a command line and press return, the tutorial I've been following has done a pretty good job of explaining along the way. At some point I am going to go back through the man page and see what the various opti...

A Quickie on OpenSSL

Posted by mirrorshades , 18 April 2008 - - - - - - · 203 views

Apparently the default openssl.cnf that comes with OpenBSD has been "streamlined" so that some stuff required by the how-to guide I'm following is missing. I'm not l33t enough to work around it, so I found that copy/pasting chunks from the OpenSSL source download of the same version seems to work OK. Have to pay attention to the error mess...

K.I.S.D.

Posted by mirrorshades , 18 April 2008 - - - - - - · 212 views

K.I.S.D... for "Keep It Simple, Dumbass"I don't know much about RADIUS as a protocol, and I don't know much about the FreeRADIUS app. I have used Microsoft's bizarro-RADIUS implementation called "Internet Authentication Service"... through which I managed to set up what I think is EAP-TLS on a domain, used for wireless and VPN authentication. I more or less clickey-clicked my way through, and couldn't re-explain to anyone else at this point how I managed to do it. (I hope it doesn't break!)Anyway, as with most things in the *nix world, FreeRADIUS uses various configuration files to keep track of the program options. I found a web-based GUI utility, called Dialup Admin, that is apparently the "official" GUI for FreeRADIUS (never mind that it hasn't been updated in the last few years). I thought it would help ease my transition into the wonderful world of AAA/RADIUS if I installed this utility. You know, just until I figured out the configuration files.
