Primer

This document describes the basic features of AFS as impletented by the Stanford Computer Science Department. If you are mainly interested in the changes caused by the NFS to AFS transition, please check What is different about AFS?

Command Reference

This document provides a summary of the most frequently used AFS commands. For a complete reference, see the OpenAFS User Guide and the OpenAFS Administration Reference.

Limiting Access

This document is incomplete.

There are a two basic ways to password-protect web pages on the CS web servers. If you want to require logins using a CSID, and possibly limit it to a specific set of CSIDs, then use WebAuth. If you need to setup a shared password, or provide access to people without CSIDs, use Apache BasicAuth.

WebAuth

Please contact action@cs.stanford.edu to discuss this option.

Personal Pages

This document describes how to setup a personal web page in the Stanford Computer Science Department.

The Quick Way

Create a 'www' (or 'public_html') directory and set the permissions on it and your home directory:

    mkdir ~/www
    fs sa ~/www www read
    fs sa ~ www l

Your web page will be reachable from several different URLS.

Computer Systems

For general use by CSD students, there is a main timesharing server plus a lab with a cluster of workstations. All of these machines are provided particularly for handling electronic mail, web browsing, and reading Usenet newsgroups. These systems are not for running CPU intensive processes, or for academic use (research or course work).

Headers

Each email you receive contains information about where the message came from and which computers it went through on its way to your mailbox. This information, contained in the message's headers, is usually masked from your view. When you display full headers, you're telling your email program to restore this information, which can be used to trace email back to its source.

Security

We strongly recommend that you use only secure network connections to access your account(s) on remote machines. Many Stanford computers will not accept insecure connections over which your password travels unencrypted. Most Stanford computers accept ssh connections.

If you use a version of SSH that supports port forwarding, you can run X Windows applications securely on your computer.

Wireless

Wireless networking allows laptop users to access network resources from locations where wiring is not available, providing increased flexibility and productivity. This document provides a summary of wireless network connectivity in the Gates Computer Science building, which is part of the Stanford Universtity wireless network. Getting Connected

Overview

The network in the Gates Building is a switched network consisting of around 40 VLANs. This network is comprised of two backbone switches with router modules. These are dual-connected via Gigabit Ethernet trunks to 25 edge switches located throughout the building. This provides the Gates Building with over 1500 switched Gigabit Ethernet ports.

Connection to the campus backbone is via redundant 10-Gigabit Ethernet links.

SUNetID

The SUNet ID is a unique 3-8 character account name that identifies you as a member of the Stanford community, with access to the Stanford University Network of computing resources and services. Your SUNet ID is a permanent and visible part of your Stanford identity:
