NEWS 2010: To speed up the application process, the application form previously available from this page is now only available from computers connected to the socket where the connection is wanted. Just plug in a computer and open a browser to be directed to the relavant form.

Terms & Conditions

The user is responsible for purchase, installation and commissioning of ethernet equipment and software drivers (etc) which support an ethernet 10 or 100baseT connection, including the cable from the wall-socket to the computer. No form of ethernet connection other than 10 or 100baseT can be used.

Users may not deal directly with the University Computing Service in relation to registration - all such requests will be dealt with by the College IT Office.

For IP networking:

• the IP number will be issued to the user by the College IT Office.
• the DNS name will be of the form: crsid.dar.cam.ac.uk
  where the CRSid is that issued by the Computing Service for the user (the same as their @cam.ac.uk e-mail address).

Use of the network socket by the client is subject to the following rules:

1. The good name of Darwin College shall not be brought into disrepute.
2. No network device other than the computer identified in the application should under any circumstance be connected to the network. This includes wireless routers or access point, switches and other network equipment. Anyone wishing to connect another device must contact the IT Manager to apply for permission.
3. You may not use your network connection to breach Copyright Law. (See guidelines at http://www.cam.ac.uk/cs/netdiv/copyright.html).
4. The use of high-bandwidth applications (such as file-sharing software, streaming audio, streaming video, internet phone/video/conferencing, Real Player, QuickTime audio/video, Microsoft MediaPlayer, Net Meeting and so on) is forbidden if they would cause significant chargeable traffic on CUDN JANET link. This includes in particular media/streaming software employing peer-to-peer (P2P) technology to distribute content which generates unnecessary outgoing traffic. Software which are currently known to do this include PPLive, 4OD, Five Download, BBC iPlayer and Spotify. iTunes does not currently use P2P technology and in reasonable use it is therefore tolerated.
5. It is forbidden to run Napster, Gnutella, LimeWire, AudioGalaxy, KaZaA, Morpheus, or similar file-sharing systems as file servers to clients outside Cambridge. They may be used as clients subject to the avoidance of chargeable traffic on the CUDN JANET link. NOTE: Several of these application's default settings will automatically place the software in 'server' mode unless they are changed. If you are not sure how to unset this, you should not install the software, or you will automatically be in violation of this condition.
6. The user's news-reader must be specially configured to use the Cambridge news server only. [Explanation: This will ensure your news-reading will not cause traffic charges to be made on the College].
7. All FTP fetches must be done by use of a web browser configured to use the Cambridge Web Proxy Cache to reduce the traffic charges to be made to the College.
8. All users must keep their system up-to-date by regular use of the vendor's update service (like Windows Update <http://www.windowsupdate.microsoft.com>). It is essential to install all Windows critical updates and service packs before first use of Internet Explorer, Outlook Express or Outlook.
9. All users of the network must have an anti-virus product running in their computer at all times, and they must keep its definitions up-to-date at daily intervals. See http://www-tus.csx.cam.ac.uk/virus/.
10. No Windows system may be connected to the college network until it has been certified free of known vulnerabilities. See the Computer Officer for details. If a Windows system is re-installed, it must be re-certified again.
11. Promiscuous mode reception or any other form of network traffic monitoring is forbidden.
12. User machines are not permitted to saturate the network by emitting an unreasonably high frequency of packets.
13. Only the IP number issued by College shall be used on the socket specified. No spoofing or attempt to use other IP numbers on that socket is permitted.
14. Only the DNS name issued by the College shall be used. Users are not permitted to register their IP number with other DNS names or aliases.
15. IP packet forwarding is forbidden (note that you might have to explicitly turn off IP forwarding with some versions of Linux).
16. It is forbidden to emit e-mail or news articles with false headers.
17. It is forbidden to emit e-mail or news articles with headers advertising that the client machine is an e-mail host. "From" and "Reply-To" headers must indicate an official host on which the user has an e-mail account, or be an @cam.ac.uk address.
18. Electronic mail may not be emitted other than via official SMTP mail servers in the cam.ac.uk domain, such as those at Hermes, CUS, the Engineering Dept or the Computer Laboratory. It is generally expected that outward e-mail will be emitted via the SMTP mail server on which the user has an inward e-mail account.
19. Usenet news articles may not be emitted other than via the Computing Service or Engineering Dept news servers.
20. Inward e-mail to private SMTP (e-mail) servers is not permitted.
21. Private news (NNTP) servers are not permitted.
22. Private routing daemons are not permitted.
23. All user machines must respond to a received ICMP Echo Request by replying with an ICMP Echo Reply. This means that you must not configure a firewall to block or "stealth" ICMP Echo. With the ZoneAlarm product, this means that you must not use the High Security setting on either the Local Zone or the Internet Zone: the highest allowable setting is Medium Security. With Windows XP, you must uncheck the option in the internal firewall that blocks ICMP Echoes.
24. Where a user machine offers a permitted service to the network, the service thereby made available must comply with relevant acceptable use policies. For instance, if a Telnet service is offered, it must not offer general computing resources to persons calling from outside the *.cam.ac.uk domain unless the usage complies with the terms and conditions of the associated rules listed below.
25. The College reserves the right to require (in cases where it is possible) that client computers run certain responder software when on-line, and that such responders shall not respond with false information. In particular, computers capable of running a "finger" service must do so.
26. It is forbidden to launch or copy applications which are subject to commercial copyright restrictions and licensing unless the client user is in possession of a valid licence for that application.
    

The penalty for breach of these rules is permanent disconnection without refund of subscription.

Any traffic cost incured by the College as the result of breach of these rules may be passed on to the user

For the avoidance of doubt, client machines are permitted to offer the following services to the network (please ask if you wish to clarify other cases):

• NFS file sharing
• LPR printer sharing
• Windows (SMB) file sharing or printer sharing
• AppleTalk file sharing or printer sharing
• FTP (File Transfer Protocol) server
• HTTP (World-Wide Web Server)
• SSH

Please note that many of the above have severe implications on the security of your computer, and you should only offer these services if you are confident that you understand the security implications and have taken appropriate precautions. This is doubly important because compromise of your machine's security might permit intruders to monitor network traffic other than your own and thereby acquire information about other users in College.

Computer games and other recreational activities which use the network are not approved, but will be reluctantly tolerated so long as other network use is not affected. Recreational use which loads the College's link to CUDN, or the University's link to Janet, is particularly sensitive and likely to upset other use.

Users are also bound by the following rules which can change without notice, and should familiarise themselves with these by following the links given or requesting hard-copies from the IT Office.
