The lecture podcasts are hosted here on skoda.net and you are more than welcome to get them right from my site. In a few hours, you can also subscribe to them off the iTunes music store. As new episodes get posted the feed will update iTunes and you’ll automatically download lectures.

This is the link to get to the podcast in iTunes: http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewPodcast?id=291329746

I will begin recording lectures in the AAC format so I can start including slides and other images in the podcast. I’m not going full video quite yet but I think some pictures might help. If you’re listening to the lectures on a device that only supports mp3, please let me know and I’ll do both formats, if I don’t hear from any students about the lecture-cast format, you’ll be stuck listening to it on iTunes or on an iPod.

The take home lab handout is now available in the Assignments area of Blackboard. I will not be in lab tonight or tomorrow night. I will be available and on campus, in the Green 111 lab on Thursday night. If you have questions about the lab or want to see me to talk about the class, please feel free to swing by. You do not need to come to lab this week but you do need to accomplish the lab.

In episode 2 I cover the OSI model (ISO X.200) and I talk about layered protocol design.  I go through the book definition of the 7 layer model and try to relate it back to network devices.   The whole rest of the course is broken out along the layers.  This coming week we’ll be spending alot of time in layer 1.

The first lecture is now available.  A few of the items I covered that are not in the book are listed here in the “show notes”  

• RFCs and the IETF live at  www.ietf.org 
• Tiers of Internet service providers: 1, 2, and 3. Check out this link for a good formal definition: smartcomputing.com dictionary

The plan is finally coming together for my podcast lectures and they will appear on the blackboard server on Monday night around 5PM. I’ve sorted out the microphone problems and collected the notes and retrieved my previous audio files.

Tonights lab is about Gnu Privacy guard. You’ll be generating your own key pair and sending various encrypted and digitally signed email messages. I’ll be doing a little lecture before the lab since this material is not covered sufficiently in the networking book. Don’t forget the read-ahead mentioned in an earlier post, that will turn this lab from a 3 hour slug-thru-it to a 20 minute in and done.
