Here's another good source of basic info on wirless: Microsoft's How 802.11 Wireless Works. Please ignore the part that talks about Zero Conf because, as with any auto-config technology, it has some safety issues. joat: 13:00:00 31 Dec 2005 |

The Full Disclosure Mailing List is discussing Richard Smith's suggestion on how to draw the attention of the NSA. A few thoughts: - Now why would you want to do that?
- I seem to remember that your IP is commonly included in the headers of traffic originating from the large webmail services.
- Why become a "person of interest" just so's you can be funny for two seconds?
It's not that funny of a joke. joat: 13:30:00 30 Dec 2005 |

Interlink Networks has a paper on " Wireless Detection and Tracking" that talks about some of the low level stuff, including packet analysis and what amounts to "heat maps". Some of it is a bit dated (WPA, WEP) but it's interesting nonetheless.

While Sean has been tweaking the server, I've been digging around in the odd corners of the site. It seems that, in the 2 or so years the wiki has been up, roughly 96 accounts have been added to the wiki in an attempt to spam/hack it. The wiki adds the account, logs the time and IP and promptly refuses any attempt to change it. (heh) joat: 21:30:00 27 Dec 2005 |

Okay, I'm having too much fun. Worked last night and this morning to get the Digium TDM400P card and the Asterisk software installed and running. In the process, I also figured out where my problem was in installing the IVTV software. (It had to do with the build version in the Makefile for the kernel.) So far, I think I've burned up all the spouse points that I earned earlier in the year. I've added a cheap 900MHz handset to act as the console phone and have driven my wife nuts with the phone (and the laptop) ringing. More stuff to add to The List of Unfinished Projects: - figure out how to stream live audio to the phone
- "adapt" the NSLU2 (saving up for a USB2 HD)
- learn more about the ivtv modules and MythTV
- get ready for next semester's classes
- get ready for ShmooCon (19 shopping days left!!)
Add that to the stuff already on the list and I'll be busy for at least 6 months. joat: 17:00:00 26 Dec 2005 |

Stand still and watch. You'll see the leading edge of the crack pass by you very quickly. What am I referring to? How about the fracturing of the Internet? InfoWorld has an article about a Dutch company (UnifiedRoot) standing up their own dns infrastructure, with the intent to run it in parallel to the ICANN managed namespace. Call me a sadistic pessimist but this topic is going to be "interesting" (Chinese curse version) to watch and has a high entertainment potential. This sort of thing has been tried before and has taken some intriguing turns. (Hint: the proposed managers of the .XXX domain are the same people that used to sell you the domain under ALTERNIC, for less money.) You'll need popcorn and some soda for this one folks! (I predict a lot of nasty politics, both external and internal.) Update: Still think I'm kidding? How about this: the site recommends that DNS owners replace their hints file with one from UR. A quick look at the file reveals none of the normal DNS root servers are included. Yep, that's right, rather than the cooperation the web site touts, they want you to trust them implicitly. This should get interesting quickly. joat: 13:30:00 25 Dec 2005 |

Please standby. The powers-that-be (again, mostly Sean) are working to get the system back up and running. Some of the custom code (mine) has to wait on final system tweaks before I attack it. joat: 04:10:22 25 Dec 2005 |

While we're on the subject of DNS tools, dnstop may be a useful tool if you manage a network. It's a bit simple but will keep track of which host is doing how many DNS lookups. For home networks, it's a bit useless as it needs to listen to a gateway feed. You may find it interesting in any case. joat: 21:30:00 22 Dec 2005 |

dnstracer is an interesting tool. It traces information from DNS back to its source. It does this by using non-recursive queries. In other words, if you tell it to trace "shmoocon.org", it'll return the following interesting data:

While it shows that there may be a problem with TLD1 (this is likely to be a problem with the tool's ability to handle IPv6 data rather than the server), you can see that the tool queries all of the DNS servers that are known to have the data. (68.10.16.25 is the IP of a DNS server local to me). This tool also has the ability to detect lame DNS servers (those that are supposed to know the answer but don't)(think misconfigured or damaged secondaries). If anyone is really proficient with this tool, please contact me. I'd like to know if it is useful in detecting record poisoning. joat: 21:30:00 21 Dec 2005 |

If PJ (at Groklaw) ever gets around to writing a book on the SCO v. The World cases and I fail to notice it, will y'all let me know? If she can sort out the mess, I'd enjoy reading about it. In any case, more hand-waving and finger-waggling is slated for 22 Dec. Anyone know if I how much it is to buy just one stock (currently at $4.01) and have it framed? joat: 13:00:00 20 Dec 2005 |

I've just altered my Bloglines subscriptions to remove the Geek Style feed. Visiting that site causes pop advertisements (even in a Linux-based Firefox install). I don't know about anyone else but I feel that I read are either geek-related or personal. With Geek Style, it's the usual low-grade crap in the pop-ups. Example: The usual "Your system is infected with spyware. Click here to scan for it." message. (Hint: I'm not running Windows on this laptop.) Babak, if you read this, I think the ads are getting into your blog via your webstats4u logo/link. Read this post at JNode and the following excerpts from the WebStats4U Terms of Service: - WMS entitles users to access to a variety of on-line and interactive on-line services (the "Products and Services"). Some of the Products and Services are supported by advertising, enabling WMS to provide them to you at no cost. When you use these free services, you agree to allow WMS to display advertising, including third party advertising, through the Products and Services.
- With the installation of WebStats4U on the site it is accepted that WMS has the right to place advertisements on the site in any format or through any channel, including but not limited to e-mail, layer ads, pops, banners and other usual formats without any forewarning and it is furthermore accepted that WMS takes no responsibility for the advertising content and that WMS shall not be liable for any losses incurred regarding this advertising.
I find anything more obtrusive than Google Ads to be offensive. Google Ads are passive and easily ignored. I'll probably resubscribe at a future date but only after the WebStats4U thingy goes away. joat: 21:30:00 17 Dec 2005 |

Is there any way we can strip a Doctorate from someone absolutely clueless? Dr. Carrigan believes that the Internet is wide open to infection from alien (as in off-world) computer viruses. I have problems with a number of his anthropomorphised assumptions: - Where'd they get the 8086-series chips? Dr. Carrigan seems to assume that silicon and the various doping elements are as plentiful there as they are here.
- Are they running Microsoft Windows? If so, how are they getting their updates? I assume they'd be easy to track on Patch Tuesday. Also, I believe Bill would like a word with them about licensing. Actually, taking into account the speed of light, it means that Windows was in use decades (if not centuries or millenia) before it's availability here on Earth. We may need to talk to Bill about his patents and licensing practices.
- Infection by off-planet source would happen in one of two ways: either intentionally or accidentally. If intentional, it means they know we're here and network infection is likely to be the least of our problems. (Somebody call Tom Cruise!!) If unintentional, we need to prompt the anti-virus industry that they need to start including sub-routines to counteract alien worms and viruses.
- If there is a risk of infection from exterrestial sources, what risk do we pose to the galactic community with the problems that we have in our networks? Could that be why no one has contacted us yet? (All claims by the UFO community aside.)
In any case, I hereby nominate Dr. Carrigan to be the recipient of a Reynolds Wrap hat. Shiny side out, dude! Update: the above is a bit dated and lived in my slush pile for a bit but is still amusing. joat: 21:30:00 15 Dec 2005 |

This will a hint to tell how old I am (at a minimum): I'm excited about discovering the TMBG podcast feed. To those that are Britney's age or younger (or those who've never heard of Login Whitehurst), TMBG is short for "They Might Be Giants". Where else can you hear a band sing in the style of Yes, Rocky Horror, the Beatles, and Leon Redbone? Then again, trying getting through the day with Birdhouse in Your Soul and Happy Noodle doing battle in your head. joat: 13:00:00 14 Dec 2005 |

Took a power hit this weekend. Lost a stereo and my home network has been acting funny every since. I thought that I'd lost the router that acts as my IPv4/IPv6 gateway because it'd only work for a few minutes at a time. Turns out that I was wrong. I'd forgotten about the print server I had picked up a few months ago (my wife is the only one that uses it). I'm not sure if it's permanently damaged yet but the network came back when I unplugged it. In any case, I'm relieved and my wife is pissed. (Keep in mind there's only one print server and two spare AP's.) I'm in trouble! joat: 21:35:00 12 Dec 2005 |

Not that it's new but I received one from a friendly Mytob worm that I hadn't seen yet. It was from veeby@fbi.gov and said "Here are your bank documents." So, if you're IP is 202.177.156.97 (India), please take a look at your system. It's infected. joat: 13:00:00 11 Dec 2005 |

It's old news (2 days) now but 802.16e has been ratified. It's important to wireless because it provides extensions to 802.16 that improves mobility (hand-offs between cells) and streaming media. Between this, podcasting and BPL (at least the noise generated by it), we may see some damage to the AM radio business. joat: 21:30:00 9 Dec 2005 |

Can RSS hijacking really be that much of a threat? If it is, I'll modify previous statements about RSS being a viable vector for malicious code. It still wouldn't be a good vector for the spread of malicious code but it might be a usuable vector for the introduction of malicious code. joat: 21:30:00 2 Dec 2005 |
