Welcome to the Computer Science Support Wiki!

This Wiki has information on nearly everything we do - all the computing services and policies provided by the UVa Computer Science Department (not ITS). There are also answers to some of the most common support requests we receive. If you do not find your answer here, please send mail to cshelpdesk@virginia.edu.

Systems Overview

The CS department provides a comprehensive computing infrastructure for department members and affiliates in addition to the resources provided for the entire university by ITS.

Computer Services Recharge Center Information

Networking

The department maintains our own wired network infrastructure, along with six public class-C IP address subnets. We rely on ITS for wireless networking.

Aliases

Mailing Lists

Web (http)

The CS department maintains a webserver

Personal Web pages

All users can post personal webpages on the main server via the userdir mechanism in apache. You simply create a "document root" in your home directory named "public_html", and set the permissions such that the directory (and files) are other-readable:

jpr9c@cordelia:~$ ls -ld public_html/
drwxr-xr-x 10 jpr9c staff 1024 Sep 22 14:51 public_html/

The content located there is available at the URI:

http[s]://www.cs.virginia.edu/~<username>

http://www.cs.virginia.edu/~jpr9c/

Any scripts you wish to have executed by the webserver should go in public_html/cgi-bin:

jpr9c@cordelia:~$ ls -l public_html/cgi-bin/
total 1
-rwxr-xr-x 1 jpr9c staff 40 Oct 25  2013 test.php

CMS systems

Drupal

Wordpress

MediaWiki

Aliases & Redirects

Aliases

If you wish to have a different web "namespace" than the regular ones provided by the userdir directive, or you need to host a website for a project or class which is not tied to your username, then you can request a web "alias". An Alias maps a URI to a document root. So, for example, if you create a website for your research project, separate from your personal web pages, then you could ask for:

http://www.cs.virginia.edu/my_research_project

and have that pointed to the document root (web page files) at:

/home/<username>/public_html/my_research_project

If you want such a special address, then you need to send mail to root with the above information: a URI and a document root.

Redirects

Often it is desirable to have requests for particular addresses on the CS domain redirect to a different namespace. If you need to have a URI such as:

http://www.cs.virginia.edu/<my_research_project>

redirected to:

http://www.my_research_project.org

Then we can create a redirect for you - send mail to root with the "from" and "to" URI as given above.
