ARSC hosts a public World Wide Web (WWW) server (http://www.arsc.edu/), a public FTP (ftp://ftp.arsc.edu) server, and a server hosting Staff and Researcher pages (http://people.arsc.edu/).
Public web and ftp server accounts are an additional service
ARSC offers our users. To obtain an account on our public web or
ftp host, send e-mail to 
with a brief
description of your need and usage requirements, for web, FTP, or
both. You must have another ARSC account in addition to a web or
ftp account. If your main ARSC account is ever disabled, then your
web and ftp accounts, and all files, will be deleted.
A web or ftp account is a privilage, and is governed by policies in addition to those policies that govern all ARSC accounts.
Access to people.arsc.edu or ftp.arsc.edu is through kerberos/SecurID. You must have a valid kerberos ticket in order to connect. Use kinit, or login to the console of an ARSC workstation to obtain your kerberos ticket. Once you have a valid kerberos ticket you may use ktelnet or krlogin to connect to either server. To transfer files to your web or ftp directories use kftp or krcp. If you do not have kftp or krcp on your workstation, you can use standard ftp from the web or ftp host back to your workstation. Please see our using kerberos document for more information
Do not add people.arsc.edu, or ftp.arsc.edu to the .rhosts file of any other system for which you have an account.
Because the web and ftp hosts have high profiles on the Internet, there is more likelihood that an intruder will attempt to break ARSC security using one of these hosts as an entry point. By not including these host names in .rhosts files, if the web and ftp host is compromised, your other accounts will still be secure.
Include the ARSC Research Home Pages Disclaimer on your main Web page.
The public web host is provided as a place for you to display your research. While other material is permitted on these pages, they should highlight your research activities. Please see our Research Home Pages Policy for more information.
If you wish to make a file temporarily available to someone off-site, you must have an account on our ftp host. You may then request a private ftp directory (~ftp/private/username). Files placed in this directory with world read permissions, will be available by anonymous ftp, ftp.arsc.edu/private/username/filename. Directories must have world read and world execute permissions.
The soft quota is the limit for your account. The hard quota exists only to provide short term flexibility for account maintenance.
You cannot go over the hard quota. Use quota -v to get a current report of your account anytime. If you have any problems with your quota, please contact User Services.
When your public web account is created, the subdirectory public_html is created in your home directory. The webserver will only serve files that are located in public_html or subdirectories of public_html. Within the public_html directory is an example HTML template. You are not required to use this template, but doing so will help to ensure that your research pages include the appropriate disclaimers and that all ARSC research pages have a compatible look-and-feel. When creating your pages, please be sure to set the permissions of any files you wish the public to see to world-readable (chmod o+r filename), and any subdirectories to both world readable and world executable (chmod o+rx subdirectory). Additionally, if you do not have a file named index.html in your public_html directory, a viewer's browser will show a directory listing of public_html. Once you have created your web pages and set the appropriate permissions, these pages will be viewable at the URL http://www.arsc.edu/~ARSCUserID/.
There are many good books, too many to recommend, on HTML, and many good HTML editors that can help in creating your research pages. Some suggestions:
The following directories exist within the pub directory:
| documentation: | This directory contains documents that discuss all aspects of accessing and using ARSC systems and software. |
| graphics: | All types of graphics and visualizations, from the latest research results of an ARSC user to the ARSC logo, are stored here. |
| outgoing: | A temporary pickup location for files made available by ARSC for users. |
| publications: | User publications, newsletters, technical reports, and any other publications created by ARSC staff or by ARSC users are placed here. The publications are placed in separate subdirectories, such as newsletters, user_reports, abstracts, etc. |
| software: | This directory contains programs that ARSC users may find useful. Executables are stored in the binaries subdirectory, usually in a compressed format (see FILE FORMATS below). Source code is stored in the sources subdirectory. |
| submissions: | Anyone can submit files of general interest to ARSC or its
users using this subdirectory. Please send email to  when you add a
file(s). Include in this email a brief description of the content
of the submitted file(s). Files in this directory can only be read,
rewritten, or removed by the user or ARSC staff. The files will
then be reviewed and moved to other directories as
appropriate. |
Several ftp commands are available to navigate between subdirectories, list the contents of subdirectories, and more. These work almost exactly like their UNIX and VMS counterparts (e.g. cd, ls, dir, etc.). Type help at the ftp> prompt to see a full list of commands; type help command-name to see help for a specific command.
