Web Directory Listings


How to display the contents of a web directory.

By default the webserver will look for an index.html file in a web directory and serve that. If one doesn't exist a message will be displayed about how you do not have permission to access this directory on the server. What this really means is that the web server is not allowed to simply print a list of all the files in that directory to the screen.

It is useful sometimes though to simply use a web directory as a file repository for easy web access.

CS Course Instructor Home Pages

URCS Acceptable Use Policy for User Administered Machines


Labcomm Acceptable Use Policy and Guidelines for a Machine(s) Connected to the URCS Network Inside the Firewall and Maintained by a Non-Staff Individual or Research Group.

URCS is under constant attack from outside hackers -- thousands of break-in attempts EACH DAY. Our security policy is organized, in general, around the principle of trusting each other within the department, but distrusting the outside world. We have a fairly strong firewall, but inside it root access on one machine is enough to compromise all other machines.

Lab staff works very hard to keep the firewall secure and to avoid security vulnerabilities on all staff-maintained machines. Among other things, staff members install security patches very aggressively; scan activity logs for suspicious behavior; run cracking programs to search for weak passwords; and perform extensive postmortem forensics on every successful attack.


The weakest link in department security is user-maintained machines. Since these are obviously essential to much of what we do, it's important to have some guidelines for them. If you attach a personal machine (e.g., laptop) to the URCS research network (wired or wireless), or if you assume responsibility for a research or teaching machine, you should

Information about using your email account at URCS

There are a variety of ways to access your email account at URCS.

Disk Space Policies


CS Department policies for disk space usage.

Your home directory is where your course work, email, etc belong. Typically there are several users that share a filesystem for their home directories. On the research network there are no quotas for home directories. If the space fills up, work it out with those you share the filesystem with. If the out of space problem becomes chronic, contact the staff and we will look into moving 1 or more users to an alternative space. Your home directory is for files related to your work in CS. You should not import your life history of email, your music and movie collection, etc.
