It won't be long before wintry weather threatens the Omaha area. If poor weather conditions force the University to close for all or part of a day, your most reliable source for accurate information is the Creighton University weather hotline at 280-5800.

Final class! What I would like is for each group to present their experience with their network set up to the entire class. You will also turn in a report detailing your configuration (follow this link for format) to me so I have a record.
Due to a funeral, I will not be in the office on most of Monday. I should be back sometime in the mid-afternoon. If you have questions or problems with your assignment, send them to me via email. I will be available via email to answer questions on Saturday morning and evening, and on Sunday morning.

UPDATE: Yesterday (Tuesday 4/8) I reviewed the masquerading code for the Linux group, and found some things that might have been causing problems. Once I cleaned up the code, it worked great! So now the Linux group has their network set up. I also spent some time with the W2K server group, and have no joy to report. I had Ken Mattson, another network guy on campus, take a look at it and he could find nothing wrong. There are some suspicious entries in the event viewer though, that make me wonder if there is not something wrong with the hardware. I have nothing to report on the Win98 group yet.

HIPAA is coming. Have you been getting privacy notices from your insurance companies?
Today's plan: Catch up on the OS installations. Before we leave tonite, every team's network should be operational. You have had two weeks to research your particular networking setup so we should be good to go!
Also, in the next weeks we are going to cover Panko's chapters ten and eleven. Those chapters deal with security and administration. For a start, look at CU's security site.

My plan for the rest of the evening is to install your OS.

A question was asked about the assignment in regards to the HP color laser printer. It seems that HP has removed the info from their website on the product. Oh well - just assume that the printer has only a parallel port connection and that you want to hook it directly into the network.

OUT OF THE OFFICE - I will not be on campus this week, with the exception of class, as I will be taking Linux administration training at the AIM Institute. You can email me, or leave me a voice mail and I will return the message in the evening. Class may run long, so give me until 6:30pm. If I am not here by 6:30, then there is no class. I will also be able to email from class so I will post a message to the class list if I won't be able to get back down to campus on time. Based on the class last month, I should be able to be here on time.

Paranoid users? Paranoid security team?
"25 years ago today (2/16/03), Ward Christensen and Randy Suess officially announced
the creation of a little project they threw together with a 300 baud Hayes modem, a Z-80 based S-100 computer, and a phone line. They called it
"Chicago Bulletin Board System" (CBBS) and it was the first dial-up BBS.
From this beginning, BBSes grew into the many thousands and became an entire industry, and when the Internet started to mature with the World
Wide Web, the users who had cut their teeth on BBSes moved over to it. So raise a toast to these two fellows for a quarter century of great online
times."

SD Supercomputer Center Researchers Find Unnecessary Traffic Saturating A Key Internet 'Root' Server
| MS SQL Server Worm Wreaking Havoc |
from the no-man-will-know-the-day-or-the-hour dept.
defile writes "Since about midnight EST almost every host on the internet has been receiving a 376 byte UDP payload on port ms-sql-m (1434) from a random infected server. Reports of some hosts receiving 10 per minute or more. internetpulse.net is reporting UUNet and Internap are being hit very hard. This is the cause of major connectivity problems being experienced worldwide. It is believed this worm leverages a vulnerability published in June 2002. Several core routers have taken to blocking port 1434 outright. If you run Microsoft SQL Server, make sure the public internet can't access it. If you manage a gateway, consider dropping UDP packets sent to port 1434." bani adds "This has effectively disabled 5 of the 13 root nameservers LINK TO SLASHDOT ARTICLE IS HERE eEye security bulletin here. MSNBC article here. Oh, and Microsoft activation servers are down as well, so you cannot register and activate any MS products. Many ATMs were out of order. Check out the Internet Traffic Reporter here.
Related to this, as I write this at 10:42am on Saturday, for the last two hours the University has been off-line. I can access COBA resources but nothing in the Computer Center. Their telephone hotline was last updated shortly before 9:00am and reported no problems, and I cannot reach the http://itnotices.creighton.edu page to see if it is updated. UPDATE at 11:00am - after talking to an operator, it seems that the Computer Center has isolated itself from the rest of the world. No connection to any machine in the Computer Center server room is possible. No timeframe yet as to when the connectivity will be restored. That is why you can connect to other servers on campus (like this one) but not to email, http://www.creighton.edu, etc. UPDATE at 2:30pm - the entire University is offline now, and the x1116 number has not been changed. UPDATE at 3:40pm - part of the University servers are back. I can get into Bluejay, but not anything in COBA. The ITnotices page is not updated and the phone message has not changed since 11:00am. UPDATE at 4:30pm - Some CU sites are back, but nothing outside of the computer center. Hotline at x1116 has not been updated since 11:00am. A few email messages are trickling through to the outside world. 424 messages queued on Bluejay. UPDATE at 7:00pm - the recorded message at x116 has been updated and JD states that our network is down to the SQL worm going around. I know that they have a few SQL servers in the server room. Connectivity is still down, although I can get to Bluejay. Email is not going through and I cannot update our class web pages (I am updating this at home from a copy saved here). UPDATE at 7:36pm - CU's connectivity to the Internet seems to be back up, I am going to try to save these updates and check the mailqueue.
On Bluejay, try the command mailq. Then pipe it through wc, (the command to type is mailq | wc) which counts lines to give a rough estimate of the number of messages in the queue on Bluejay. At 15:55 the number is 477.

Welcome to the first day of class!
Be sure to join our class mailing list, this is very important. Details are below.
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.
