  • 300 computers

  • 525 users

  • 2 computer instructional labs

    • Jeffrey L. Star Lab (Ellison Hall, Rm. 2610)

    • Descartes Lab (Ellison Hall, Rm. 3620)

  • 1 grad student-only computing lab

    • [email protected] Lab (Ellison Hall, Rm. 2616)

    • Ellison Hall, Rm. 2620

    • Ellison Hall, Rm. 3621

Slide10 l.jpg


  • UNIX accounts

    • Password matches your initial e-mail password

    • Forgot it? Visit Gwen or Mark for a new one (passwords never

      e-mailed out), at Ellison Hall, Rm. 1839

    • You can change your UNIX account password using Secure

      Shell Client or X-Windows terminal client

      • e.g., on, use

        yppasswd at the command prompt, and follow the instructions.

  • Useful Departmental UNIX servers to SSH into

    • whizbang (

    • latitude

    • isoline

Slide11 l.jpg


UNIX – huh! - What is it Good For? Absolutely…

  • Powerful

    UNIX as an operating system can support almost any kind of software. Manage and alter vast amounts of data/files/directories with simple scripts.

  • Flexible

    UNIX offers thousands of tools that can be combined and recombined. Or, create ones custom to your needs! Connects with Windows Explorer by mapping a network drive. (e.g. \\latitude\username )

  • Reliable

    UNIX is hard to crash.

  • Simple

    GUI-free. Shamelessly “borrow” source code, modify, compile, use!

  • Fashionable

    UNIX is anacademia OS. UNIX user = instant uber-computer geek cred.

Slide12 l.jpg


  • Class accounts

    • These are UNIX accounts. For instance, Jane Q. Doe taking Geography 184 would have an account named jqd184

    • But, they expire quarterly/yearly

    • Useful for students’ class-related webpages

Slide13 l.jpg


  • E-mail accounts

    • Change password, set forwarding and vacation


    • Open with

      Internet Explorer (not Mozilla Firefox)

  • Spam filtering

    • 90-95% of all e-mail we receive is spam

    • All UCSB computers are whitelisted, and therefore not

      filtered for spam

    • Quarantine account:

Slide14 l.jpg

Web Pages

  • Personal web pages(created & managed by you)


  • Create public_html folder/directory

    • index.html – your default ~username page

    • Use SFTP/WinSCP/etc. to transfer/command line or map a network drive in Windows XP Explorer

  • Class web pages(established by webmaster, content created by you, managed by you and the webmaster)

    • /www/classes/

2007 - 2008 in Review

  • An external Program Review Panel (PRP) report in 2007 remarked that they were “shocked and dismayed by the poor quality of instructional computing facilities in the Geography Department; the situation is especially distressing in that the Department’s international reputation rests largely in the area of the application of information technologies of geographic problems.”

  • Our response outlined a plan to overhaul major shortcomings.

  • Establishment of a computing space to support the [email protected] mission, as well as provide a graduate student computing facility.

  • Implement security measures to protect Department computing property.

  • Re-invent Department’s Web image.

  • Procurement of new hardware & software.

  • Immediately execute the 94 action-items in the PRP Response…and so it began…

ArcGIS Server 9.3

Tasks and Roles with an ArcGIS Server

Slide36 l.jpg

ArcGIS Server 9.3

GIS Resources are assets you create using ArcGIS Desktop

GIS Services are GIS resources available through the Web

NOTE: Due to security concerns, Web applications that allow an end-user editing directly to the geodatabase won’t be available right away. However, through ArcGIS Desktop in-house (labs) are OK.

Slide37 l.jpg

Currently students have ~100MB disk space quota on the UNIX network.

This hardware has not been ordered. Added into the PRP Response as a requested addition.

If funded, would eventually provide each graduate student with 120GB of network disk space.

The End network.

…and then there’s printing.
