CSL Wireless And Laptop Network

The CSL is in the process of installing 802.11b wireless networking and a 100bT "laptop" network for use in the Computer Sciences and Statistics building.

CSL Wireless And Laptop Network

Introduction

The CSL Wireless and Laptop Network is designed to allow users access Computer Science network resources as well as the Internet, from a laptop using either an 802.11 wireless ethernet card, or a wired ethernet connection.

In order to protect our resources and be able to identify and isolate problems, user of the network will be required to authenticate before being allowed to access any network services. In addition, some CSL network services (such as printing) will be provided via transparent proxies, to minimize the inconvenience for users.

SSID Or Wireless Network Name

The wireless SSID for the Computer Science wireless network is "tsunami". The Statistics wireless network uses the SSID of "stat_wireless".

Coverage Area

Our goal is to cover all Computer Sciences Department offices, conference rooms, and major classrooms.

Wireless access points are installed in the following locations of the Computer Sciences and Statistics building.

Authentication

To authenticate to the network, open an ssh session to wireless-gw.cs.wisc.edu (128.105.48.1). You will be prompted for your CS user name and password. Once the session is established, your laptop will be allowed to access the network and proxied services will be enabled. When the session is closed, access will be removed.

The ssh session can be established using any ssh client, such as OpenSSH for Unix, SecureCRT for Windows, Nifty Telnet SSH for machintosh computers, or mindterm (a java ssh client that can run stand-alone or in a web browser). Clients can be downloaded from various locations on the web, or (on the wireless/laptop network) from the authentication gateway prior to authentication.

Prior to authentication, all requests for web pages will be redirected to a web page with authentication instructions and ssh clients for download.

Network Configuration

Computers on the wireless and laptop network should be setup to use DHCP for network configuration (a dynamic IP address will be assigned). See the previous FAQ entry for information on the SSID in use on the wireless network.

Wireless Hardware

The wireless network access points are Cisco (Aironet) AIR-AP1200 access points. We recommend the following wireless network cards for your laptop:

Cisco (Aironet) AIR-PCM340 PC Card client adapter
Lucent ORiNOCO PC Card - Silver
Lucent ORiNOCO PC Card - Gold
Apple AirPort (mac only)

The CSL Wireless network is configured to not use encryption.

Wireless WiscWorld Authentication

The CSL Wireless and Laptop Network was funded by the Computer Sciences Department. As such, our priority is service to faculty, staff and students of the Computer Sciences Department.

At the present time, only users with CS login names and passwords can use the network. We hope to add Wireless WiscWorld authentication in the future.

Printing From The Wireless/Laptop Network

User of the CSL Wireless and Laptop Network can print to CSL printers after they are authenticated. The authentication gateway will add your user identification information to printing requests. If you have a print quota, your quota will be charged for pages printed.

To print to a CSL printer, configure the printer as follows:

On UNIX systems:

Different Unix versions use different printing software. Most use a variant of lpd. Configure the printer you wish to use as a remote lpd printer. The remote print server is print.cs.wisc.edu.

Linux users may want to use CUPS to configure driver support and advanced printing features. PPD files for CUPS configuration configured with options installed on our printers can be found in /etc/cups/ppd on any supported linux desktop computer for each printer in the department. Printer models are itemized in the next section.

On Windows NT/2000/XP systems:

Open Start Menu
Select Settings
Select Printers
Run Add a new Printer
Check Local printer
Un-check automatically detect plug-and-play printer
Check New Port
Select Standard TCP/IP port
input the Printer Name: print.cs.wisc.edu
input the Port Name: Use name of the printer you want to use
(this takes a while)
Select Custom Settings
Check LPR
input the Queue Name: Use name of the printer you want to use (2a, 3a, copier-5, etc)
Check Use LPR byte count
Name the port by the name of the printer
Check no port sharing
Select a printer driver to use with the printer:
- laser: Lanier LP145 PCL6
- graphics-vision/melody: HP LaserJet 4100 Series PCL 6
- 4310, cathy: HP LaserJet 3005DN PCL6
- other admin staff: Lanier LP128n
- c5-paper/c5-slide: Xerox Phaser 6250DP (PostScript)
- c4/c6/c7: Xerox Phaser 6360DN (PostScript)
- copier-5: Lanier LD275 PCL6 (the stapler/finisher model is an SR970)
- copier-2/copier-3/copier-4a/copier-4b/copier-6/copier-7: Lanier LD345 PCL6

Note:HP Driver downloads can be found at www.hp.com. Xerox driver downloads can be found at www.xerox.com Lanier driver downloads can be found at www.lanier.com

On other Windows systems:

Other windows versions do not support lpr printer ports, so they can not be used.

What Is The Cost Of A Connection To The Laptops And Wireless Net?

This depends on the nature of the connection which you have. If the connection is via the wireless access points, there is no charge for the connection. If the connection is through a wired connection in an office, the connection is billed as a minimal chargeback workstation. The advantage of the wired connection is a 100Mb switched connection instead of an 11Mb shared connection. For more information on chargeback, please see the chageback faq.
