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.
