Something about the keypad use and seeing what the next level had in store...Last night I finally got to level 20 (the last level). Hooray. http://www.eyezmaze.com/tontie/v1/index.html (9 comments) dlidbom@mindspring.com http://www.mandatorycurfew.com/Default.cfm?Page=Journal&Permalink=Yes&JournalID=722 Wed, 20 Aug 2008 00:00:00 EST http://www.mandatorycurfew.com/Default.cfm?Page=Journal&Permalink=Yes&JournalID=721&Comments=3 Facebook accidentally publicly revealed personal information about its members, which could be useful to identity thieves. Earlier this month, the full dates of birth of many of Facebook's 80 million active users were visible to others, even if the individual member had requested that the information remained confidential. According to Graham Cluley, senior technology consultant at Sophos, a security slip-up by the website during the process of a public beta test of its new design for members' profiles left birth date information exposed. "I was shocked to see people's full date of birth revealed, even though I knew they had their privacy set up correctly to supposedly hide the information," said Cluley. "It's essential that users of social networks should have confidence that their privacy will be protected - and it's especially important with information like your date of birth, which can be a golden nugget for a committed identity thief." Cluley says he informed Facebook as soon as he discovered the flaw, which now appears to have been fixed. "It's good that Facebook fixed the problem - but can people feel confident that this kind of mistake won't happen again in future?" he asked. "My advice to Facebook users would be, even if your date of birth is set to be non-visible, change it to a made-up date in case this kind of blunder happens again. Facebook and other social networking websites need to be more careful about protecting their members' data, or risk losing users." http://www.securitypark.co.uk/security_article.asp?articleid=261853&Categoryid=1 (3 comments) dlidbom@mindspring.com http://www.mandatorycurfew.com/Default.cfm?Page=Journal&Permalink=Yes&JournalID=721 Mon, 28 Jul 2008 00:00:00 EST http://www.mandatorycurfew.com/Default.cfm?Page=Journal&Permalink=Yes&JournalID=720&Comments=3 I caught another bass and a northern pike today.

The present I got was 27 mosquito bites that itch more than anything I can remember (yes, Scott, even the poison ivy from our "brush-clearing" expedition).

It's a good time, aside from the occasional monster break-downs and mosquitos. Here's a pic of Isaac and Jake playing at the beach at the lake.

It is much better than sitting outside...more quiet, better views of the aircraft, tvs you can control, free snacks and drinks. Not a bad place to get a few hours work done before a late flight.

For all the domain controllers and computers to talk nicely to each other on a Windows network (and other networks relying on Kerberos/most modern authentication mechanisms), the system times need to be relatively close to each other. Not to mention if your mobile devices (say Blackberries) are more than two minutes or so off of your workstations you will have all sorts of users who are irritated because they looked at their workstation and thought they were late, only to get to the meeting and see on their mobile device they weren't late at all. The general idea of time synchronization on a Windows network (assuming 2003 Server) is that there is one server for the domain (the one that holds the PDC Emulator role) that is authoritative for time synchronization. That system's clock is to be set with a hardware device, the system BIOS clock or by using NTP to talk to a reliable time source over IP. All of the other servers get their time using "domhier" which is the domain hierarchy Microsoft has created that hopefully efficiently synchronizes time (talk to the closest server, make sure there is a small variance in what you expected, etc.). Then client workstations synchronize their time with available domain controllers. This is over-simplified, of course (there are all kinds of neat algorithms and such Windows uses to try to make this process efficient). In the issue I was working on last night, the PDC Emulator role had been moved from one server to another to another. Microsoft has knowledge base articles (http://technet2.microsoft.com/windowsserver/en/library/4a63190b-c594-4d43-9195-e54e4cb89d251033.mspx?mfr=true, Link ID 91969 and others) that explain what to do on the old PDC Emulator so that it does not think it is the authoritative time server for the domain anymore. I completed these steps (along with the steps required on the new PDC Emulator) and confirmed every domain controller in the domain except the PDC emulator was set to point to domhier. I configured the PDC emulator (domain controller on a virtual machine) to point to a reliable NTP server online. Happy I had built a Microsoft-approved Windows time configuration, I waited for the time synchronization to happen, then I forced it with a command line (w32tm /resync /rediscover). The PDC emulator's time would synchronize with the NTP server and then the time would change back within a minute. I re-verified everything three times. Everything is right, but the whole domain is getting the wrong time (relative to atomic time) because the PDC won't keep the correct time with the NTP server. I was pulling my hair out. I found out how to turn on debugging in the Windows Time Service (http://support.microsoft.com/kb/816043). After turning it on, there was not much help in the logs. They would just show the time changing backward about 4 minutes after every time synchronization. It just didn't make sense. Until I had a revelation... Here's the reason for this article...because after hours of work and searching online, no one seems to have documented this... Microsoft Virtual Server 2005 was changing the time on the guest operating system (Windows Server 2003) running the PDC Emulator WITHOUT LOGGING ANYTHING ON THE GUEST. There you have it. I haven't dug enough to see if it logged anything in Virtual Server or not, but it would have been really really nice if it had let me know somehow on the guest OS that it was changing the time. I setup the Virtual server to sync it's time with the NTP server and all is well.

I'm still shaking my head that they thought it had enough credence for them to try it. I will leave their names out until they decide to defend themselves. All decided to abort the experiment when I began to try to capture it on video. Search youtube for popcorn cell phone if you're unfamiliar with this.

I decided this evening to bring it back out, although it took a lot more code-massaging than I would have liked because of the architectural changes to my site in the past 7 years or so. Who of you has been visiting my site long enough to remember when I had this theme up previously?

As usual for a mac, it has very little information that would help a technical user. I found it interesting. My guess is it has something to do with the "Michael algorithm" used in WPA...here's a paragraph from Wikipedia: "The Michael algorithm was the strongest that Wi-Fi Alliance designers could come up with that would still work with most older network cards. Due to inevitable weaknesses of Michael, TKIP will shut down the network for one minute if two frames are discovered that fail the Michael check after passing all other integrity checks that would have caught noisy frames. It will then require generation of new keys and reauthentication when the network restarts , forcing the attacker to start over." Anyone else ever seen this?

Rather than re-iterate, I'll link to the apple thread where people are chronicling their problems: discussions.apple.com/thread.jspa This has been infuriating (and an open issue for at least 6 months). I have swapped out routers, changed every configuration I could think of, etc. Finally, I forced my router into 802.11g only mode (instead of b/g or n) and it has been working for a few minutes at least.
