I'm looking up some resources for those two groups still having problems, namely the NT and W2K groups. Kind of funny - I thought those would be the first ones done. Anyway, since this is the last official night of class, I will be opening the room early, around 4:30pm. That way your groups can come in and that will give you nearly 2 hours before class to get some more work done.
Last scheduled class period! Last night to do a Tech Tip If you don't do your TT tonight, you won't have another chance.
An example of the importance of physical security
Where were you at 9:40am last Tuesday morning? Power outage on campus! Lasted about 75 minutes, and it took another hour or so to get everything back to normal.
We will be having a quiz tonight. It will be multiple-choice and consist of 12 questions. And no, it won't be posted on the bulletin board until after the class! (thanks for asking, anyway). I will also pass out our final quiz, and it is due on Friday. It will be a take-home quiz, using NO notes, NO books, nor any collusion or group work.

Gigabit ethernet prices in free-fall
I had a comment from a student about the quiz, saying that "they" could not find the answers. Didn't I make it clear that this was an individual, no notes/books quiz? Based on the grades, it appears that was not followed. We are going to discuss this in class on Monday.
Looking at the schedule, we only have four more
classes after tonight! So here is my plan:
April 8
Finish Panko, chapter 6
Group work on projects
April 15

Information on upcoming quiz 5 and quiz 6. I plan on quiz 5 for tonight, Monday, March 18 (pending time of the guest speaker) and Quiz 6 on Monday, March 25. I plan to update the overall quizpage regularly.
Assignment One due on Monday, March 25 (individual project)
Assignment Two due on Monday, April 1 (group project)
Assignment Three due on Monday, April 8 (group project)
FCC NIXES MORE CABLE BROADBAND REGULATION
The Federal Communications Commission ruled that Internet access via
high-speed, interactive cable modems should be classified as an "information service" rather than a "telecommunications service," a
decision that liberates cable companies from the more stringent common carrier regulations that govern most telecom companies. The agency also
ruled that cable modems did not qualify as a "cable service," which prevents local governments from creating and selling separate franchises
for cable ISPs or levying higher fees on cable companies that market broadband services. Consumer groups protested the decision, saying that it
could lead to cable company control over pricing and over the content their customers can receive via broadband. (Financial Times 14 Mar 2002)

Q&A with ICANN's security Chairman
ASSIGNMENT - for your group project, a Configuration Plan needs to be laid out. See the link for more information. In class tonight I will talk about a different way we are going to work with hardware than what I originally planned to do.
TECH TIPS - we are behind on doing these, so first thing in class today we will do those from last week and those from this week. Be prepared to do your tip. Make sure that you type out a description of your Tip and turn it in during your presentation. If you do not turn in a printed description of your tip it may not be graded.
Guest speaker update: Jack Winslade is coming on Monday, March 18th to talk about how Sitel handles their WANs and LANs, both data and phone. I am also working to get a speaker from Cox to come and talk about their Internet, Phone and Cable service.

Here is a link to the University network documentation site. This is pretty good stuff - I am sure we will refer to it often during class.
This server, eden.creighton.edu, was down on Sunday and early Monday morning. I'm trying to figure out why from the event logs. Sorry about that!
Did you get this message from Postini?

Class note: I have arranged a tour of the campus switchroom for next week, February 4. I am asking everyone to come to class early, so that we can start at 6:00pm. We will meet in BA 111 where you will leave your backpacks, books, coats, etc. and then proceed to the location. This is a first for us - the first time that any class has gotten a tour of the switchroom. Anyone not in the classroom when we leave it around 6:10pm will not be able to make the tour. No backpacks, bags, etc. on the tour please! Our guide will be Rick "Bro" Brokofsky, Director of Telecommunications. Check out the department org chart here or look at this picture of Larry Sheldon in the switchroom. This is going to be fun!!

Before Class Stuff
Class Mailing List
Everyone needs to join our class listserv, as I will send
out announcements, sample questions, etc. to the list via email. I
cannot make you join, but you will miss out if you are not on the list and
I am not responsible for any material you miss if you are not on the list.
To join the list, do the following:
* send a message to majordomo@creighton.edu
* in the body of the message, put the words subscribe mis470
* send the message
This list is closed and unmoderated, meaning that you cannot join without
my permission. Once you are in, you can post a message to
everyone on the list. I recommend that you use your Creighton email
account, as free services such as Hotmail and Yahoo have quotas or stop
their SMTP services. I am not responsible should you use a free
service and do not get your messages from me.
