News bulletin #175
23-December-2001

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.

• 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

• 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 number
• 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.

• 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 package.

News bulletin #171

• CodeRed worm
  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.

23-July-2001

• 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. Thanks"
  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

• 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

• 136680
  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).

• 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 yehavi@vms.huji.ac.il.

News bulletin #166
27-February-2001

• WEBmail
  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 https://webmail.huji.ac.il. Note 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.
