Important news for all CS Department Members -

The web interface to the WREQ problem reporting system is now accessible from all locations at http://www.cs.sunysb.edu/~wreq. You can also submit a problem or request simply by sending mail to WREQ at cs dot sunysb dot edu from your department account.

We encourage both faculty and graduate students to use this method for sending requests and questions to the systems staff. Some of you are using it already and ultimately all systems related problems, questions or requests will be funneled through this tool.

Online, go to http://www.cs.sunysb.edu/~wreq/ to post a request, view a request, or see a tutorial on its use.

The campus network group has also announced that they are running timeservers on the following hosts: time.stonybrook.edu, tick.stonybrook.edu, tock.stonybrook.edu. They request that you do not use nocnoc.sunysb.edu as a name for time/ntp.

PCs and Laptops

If you are using Netscape with ssh tunnels to send email:

When an outgoing email is scanned by Email Scanning, instead of being sent directly to your Internet service provider (ISP), it is sent to a temporary holding area where it is scanned by NAV for viruses. At that point your email program sees that the email has been sent and, depending on how your email program has been configured, will either delete the email or add the email to the sent folder. When NAV is finished scanning the outgoing email, it will send the email to your ISP.

If your Internet connection is terminated before NAV is finished scanning and sending the email to your ISP, and if your email program has been configured to save sent emails to the "Sent" box, then you must resend the email by forwarding the email from the "Sent" folder of your email program. If your email program is configured to delete sent emails, then the email will be deleted.

This scenario affects two situations
1. If you get disconnected just before NAV sends the message to your ISP.
2. If you are using ssh with tunnels and your ssh session gets disconnected. In this case, your email program will put the email in the "Sent" folder, but the email is never sent.

To get around the above scenarios, you can do either one of the following
1. Disable scanning of outgoing messages.
2. Change the ssh tunnel "smtp" port to anything other than port "25" (for example port 2500). This effectively disables outoing scanning for the application that you are using ssh tunnels with. However, if any other application/virus/trojan uses port 25, it continues to be scanned by Norton Antivirus.

Quote from http://service1.symantec.com/SUPPORT/nav.nsf/pfdocs/2001082921552806
NOTE: Disabling email scanning does not leave you unprotected against viruses that are distributed as email attachments. NAV Auto-Protect will scan any incoming files, including email, as they are saved to your hard drive. Email scanning is just another layer on top of this.

New Facilities

Room 2311, the new Seminar-Multi-Media Teaching Room opened on February 12 with a talk by David Patterson as part of the Distinguished Lecture series. It will be used for the remaining talk in this series and will be available in March by reservation for classes and seminars. A whiteboard is on order as is an improved podium.

Future plans

Room 2314, the former biology research lab, will be renovated into space for the Media Networks Lab and the Wireless Netork and Simulation (WINGS) lab. This renovation will begin around April 2nd (not the 1st) and be completed on or before May 1st.

Building Repairs

The department has arranged for the campus Heating and Ventilation crew to replace broken thermostats and heaters. Please let Kathy know if your office or lab needs repairs.

5. The Stony Brook Community

Work continues on the graduate student database which will be used by the department to track graduate students from application through graduation.

6. HOW TO REPORT A PROBLEM or MAKE A WORK REQUEST

6a. First you should check the FAQ pages at:

http://www.cs.sunysb.edu/FAQ/index.html

There is also a link to an index of FAQs.

6b. If the answer to your question is not in the faq's you should use wreq to report the problem or make a work request.

There is a short blurb on wreq in the faq area (search by index)

Wreq lives at:
http://www.cs.sunysb.edu/~wreq/

6c. You can also send email to: WREQ at cs dot sunysb dot edu from your dept account, or campus account. The subject line should cover what is wrong or what you need. The body of the email can supply any details.

6d. Your problem report must include the following information for us to be able to help you promptly:

1. The room you are working in, either room number or lab name.
2. The name of the host you are working on (hostname command in Unix, machine number in 1239, the number written on the bookshelf by your desk in the student offices).
3. The sequence of things you did just prior to having the problem as best you recollect.
4. The exact text of any error message you see on the screen, or a complete description of the problem that occured.

Please report problems promptly as they occur so they can be investigated under the same set of conditions as far as possible.

When in doubt, feel free to send email to:

Unix and network problems: ROOT at cs dot sunysb dot edu
PC problems: NTADMIN at cs dot sunysb dot edu
