Jargon

CRSID

CRSID stands for Common Service Registration Identifier, and is your unique id that is used to identify you with every computing service in Cambridge. It is composed of your initials followed by numbers to make up the length to 5 (or 6 if you have five initials). The three main usages are for Hermes, the PWF and Raven authentication.

PWF

The PWF is the University Computing Service's Public Workstation Facility, which gives you access to the CUDN facilities from any PWF machine. For more information see the Computing Service website.

Cambridge University Data Network

The CUDN is the network that connects Cambridge University to JANET, the UK's higher education and research network, and connects every service within the university. It is an extremely large network, and so an extremely popular as a target for hackers. The University and College have introduced a number of policies to ensure safe and secure usage of the CUDN.

Hermes

Hermes is the name of the mail server that manages e-mail within the university. It can be accessed using webmail, a mail client of your choice, or by ssh. Information on how to set up your mail client can be found on the University Computing Service's website here. You also have the option of getting mail redirected to the mailbox of your choice.

Lapwing

The UCS operates an authenticated wireless network at various points in University sites. Caius has installed access points in Old Courts and the library, and there are plans to put a new point in the Cavonius Center. Be aware that Lapwing is not encrypted-all data is sent in plaintext unless stated otherwise. To help this, certain protocols are restricted (IMAP, POP, ftp (use sftp or scp), telnet (use SSH) etc). Lapwing should never be used to log into a website that does not use HTTPS - if Lapwing is used to log into a HTTP website, it is trivial for anyone else using Lapwing to access your account!

It is highly recommended not to use Lapwing, but to use Eduroam instead.

Eduroam

Eduroam is another Wireless network that at Universities across Europe (including Cambridge). It takes slightly longer to setup the first time that you use it (http://www.cam.ac.uk/cs/wireless/eduroam/localusers.html) however it is far better than Lapwing:

  • Once setup you do not need to fill in a form each time you connect - it just works. The initial setup is faster than constantly logging into Lapwing.
  • There is no need to have a Lapwing stay-alive tab open.
  • Eduroam can be used to securely access websites that require you to log in.

Jackdaw

A database of user ids, names, and other useful bits of information. The same service that you will use/have used to collect your passwords when you join the College.

UCS

University Computing Service - the organisation which manages computer facilities and data networks across the university.

Bradford Disolvable Agent

Program used to quarantine computers before they are allowed on the network. Will provide updates for your computer and free antivirus software. Does not remain on your computer.
