News bulletin #175
Content sharing programs: We recently got warnings from various legal
consultants of known firms about users inside the university offering
copyrighted material to the world. The users are using content sharing
programs (like Kazaa, Napster, Gnutella and alike), download copyrighted
files to their systems and then offer it to the public (the latest example
is "Harry Potter" where the complaint has been received from
Warner Bros). Please note that such actions are considered illegal by
the university and by the law and the users involved might face a lawsuit
and/or face the university's disciplinary committee.
News bulletin #174
- Video conference services at HUJI
New experimental service, providing video conference over the network,
is available to the university's staff. The service combines video/audio
conferencing with chat and application sharing. Our server supports
multi-user conferences worldwide. For more details please see: http://www.videoconf.huji.ac.il
- Nature publication on-line
The Harman Science Library is happy to announce that all Nature
publications are online from October 1, 2001. The complete journal issues
of Nature, Nature "sister" publications and Nature Reviews
listed below are now available in FULLTEXT at present from the ULE (Union
List of EJournals).

- Modem numbers
Please note that our Jerusalem modem number is 02-6210333 and this is
the only number that Bezeq accepts for its Internet rates. Our modems
answer to other numbers as well, but these numbers are not acceptable
by Bezeq for the reduced price. Hence, make sure you dial the correct
- New security page for university users
Our security officer(Vadim
has prepared a concise page over the WEB detailing the most important
issues for our users. Please have a
visit at http://secinfo.huji.ac.il
The security information page will inform about the important security
events, new vulnerabilities, patches and updates. Also this page will
contain the recommendations for security implementation
- Large mails to Yahoo.com
Yahoo does not accept mails larger than about 1MB. It does so by aborting
the transaction after most of the message has been sent. This causes
two effects: The mail is
being retransmitted again and again, and it takes time for each attempt
(thus delaying other mails to Yahoo). Please refrain from sending large
mail items to Yahoo recipients
- Our modems support V.92 protocol
Our modems support the V.92 protocol which allows you to answer
to a waiting call and leave the modem on hold (up to 15 minutes) without
loosing your connection. In order to utilize this your modem must support
V.92 as well. Please consult your modem's book for instructions how
to use it.
News bulletin #173
- English interface for OfficeXP
Those who bought the OfficeXP package at the micro-store of the computation
center can download now the English interface of it from http://pc.huji.ac.il/XPLangPack/XPLangPack.zip
Unzip the file and then run SETUP from it.
News bulletin #172
- Sircam virus is still being spread over
We still see the Sircam virus being massively active. This virus sends
random files from your computer to random addresses, thus it might reveal
sensitive information stored on your computer or any server you are
mapping its disks. We urge you to install the latest anti-virus
News bulletin #171
This worm infects WEB servers from Microsoft (IIS) which were not
patched to prevent this worm. A lot of Windows-2000 installations
installs this service by default, even if you do not use it. Recently
we found dialup users who installed Windows-2,000 on their home machines;
when such a user dials to our modems his/her system gets infected
within minutes and then it starts spreading it inside the university.
This causes massive load on the network and service disruptions. We
suggest that if you have Window-2,000 installed and do not use IIS
to disable this service (ask for help from the one who installed Windows-2000
on your computer or ask the help of the one who sold you the software).
If you need this service then please apply the patch available on
Microsoft site at http://www.microsoft.com/technet/security/bulletin/MS01-033.asp
- IMAP Vs POP3 server
IMAP and POP3 are two ways to access your mail server from a graphical
PC client. Both protocols are implemented by the common clients like
Netscape, Outlook Express, Eudora and probably more. The main difference
between them is that POP is intended for those who use the PC as the
main store and IMAP is intended for those who work on more than one
PC and want to leave the messages stored on the server. POP3 has the
feature of "store mail on server" which allows you to access
the mail from more than one client, but this causes the mail to get
accumulated on the the server, causing access times to be slower and
fills our disks. If you receive a lot of mail and do not have important
items to save then POP3 WITHOUT "keep mail on server" is probably
your best bet. However, if you have important mail items or read your
mail from more than one PC then IMAP seems the better approach. This
way your mail is left on the server, being backed up by our operators,
and is synchronized with the store on your PC (i.e. when you delete
an item from the PC it is also deleted on the server; with Outlook Express
you have to select "Purge" after deleting items and then Tools
Sync). For more help you can contact your helpdesk.
News bulletin #170
- Sircam virus
There is a new virus which spreads itself via the Email and sends random
documents from the infected PC to random people (which might send sensitive
information out). When reading a message you can identify it by its
accompanied text which usually starts with the sentence "Hi! How
are you?", then a few other lines and ends with "See you later.
Since this is a new virus you must update your NAV definition file to
the latest version which is available at:
For more help please contact Naomi
News bulletin #169
- ADSL service
We are currently connected to ADSL on an experimental basis. In order
to connect to us via ADSL please login as user%host@IMachba (where user%host
is the same as you use at the modems). Note that IMachba should be written
with capital IM and the rest are lower case. For more information on
setting up your computer at home please refer to our manuals.
In case of problems please contact your helpdesk.
News bulletin #168
This number was part of a pilot we had with Bezeq and during the pilot
this number was given Internet rates. A while ago the pilot was terminated;
Bezeq claims they informed the universities but we never got any notice
about this. Due to that, heavy users of this number got large bills
from Bezeq. After a month of discussions
with Bezeq we concluded:
1. 136680 is still functional but cannot enjoy Internet rates.
2. People who used it under Internet rates will get a partial refund
(no details yet).
3. We'll move from a pilot to a production service whose terms are to
be announced (have to negotiate with them).
News bulletin #167
- HUJI local news groups
The Usenet (newsgroups) consists of worldwide discussion groups. Despite
that, it is possible to create local groups which are to be seen only
inside the Hebrew University. The groups are accessed with the standard
software (Netscape, Outlook Express, etc.) and can be used to share
information, most useable for courses. If you are interested in creating
such a group please contact me at firstname.lastname@example.org.

News bulletin #166
WEBmail is a WEB front-end for some Email systems of the university.
The idea behind WEBmail is that you use a browser to access your mail
instead of a specialized Email system (like Outlook expresss, Eudora,
etc.). Although it is slightly less comfortable it allows you to access
your mail from any system which has only a browser. Moreover, it supports
secure access (HTTPS) which doesn't allow hackers to see your traffic
while you read your mail. You are
advised to use it to access your mail while you are accessing it from
the internet (i.e. outside the university). To access it please open
that mail read via WEBmail is still accessible via your "regular"
mail readers, unless you explicitly deleted it at WEBmail. Currently
available mail servers through the WEBmail service are:
AGRI, AGRI3, CC, MD, POB, VMS
Problems: If you get an error message that says "Page not found"
while using Internet Explorer, then the problem might be a bug in SSL
support of IE. There are a few ways to overcome this:
1. Upgrade to IE version 5.1 or higher with 128 bits support.
2. Select Tools->Internet Options->advanced, and unmark SSL3 support
(toward the end of the list).
3. If #2 didn't help then click "Restore defaults" at the
bottom, and then unmark again SSL3 support.
- Large mails to Yahoo users
Yahoo.com is not willing to receive large mails sent to its users. The
problem is that it does not send a rejections message, but simply aborts
the sending; the sending process tires it over and over again. We suggest
that you don't send Yahoo users mails which are larger than a few megabytes
as they won't reach the recipient.
