General Network Policies

All users connected to the DTC network are expected to abide by the University's Acceptable Use Policy found at:
http://www.fpd.finop.umn.edu/groups/ppd/documents/policy/Acceptable_Use.cfm
Personal wireless access points, hubs, switches, and NAT'd networks are not allowed on the DTC network without permission from the DTC technical support staff.
It is expected that all computers connected to the network be maintained with the latest security patches for that particular OS. Any machine that becomes compromised or causes any problems will be disconnected from the network.

DHCP Network Access

The Digital Technology Center runs its own DHCP server to provide network access to laptops in conference rooms and offices. Static IP addresses will only be given to laptops in special circumstances.

To register the hardware address of the laptop on the DHCP server, send e-mail to help@dtc.umn.edu. Please specify if you are a visitor to the Digital Technology Center.
For assistance with locating the hardware address of a laptop, please refer to the ADCS webpage:
http://www1.umn.edu/adcs/network/hardwareaddress.html
Hardware addresses not used with DHCP after 120 days may be deleted from the server.

Wireless Network Access

For Visitors to the University of Minnesota:

Wireless network connections are available in the conference rooms of the Digital Technology Center. Internet connectivity is limited to basic services like e-mail, SSH, and web browsing. Users need to be aware of the insecure nature of wireless connections. Please remember to take proper precautions and view sensitive material in protocols such as SSH and SSL. It is recommended that a wired connection via DHCP be used if there is any concern for security of data. The Digital Technology Center is not responsible for any computers or information that may become compromised.

To register a laptop for wireless, send the hardware address of the wireless card and the desired username to help@dtc.umn.edu. A password will be provided for the web-based authentication system. Visitors and and seminar speakers can also register in 499.
Group logins for large conferences can be arranged in advance by contacting help@dtc.umn.edu. A single username and password will be provided for all attendees who desire network access. This username will expire at the end of the conference.
To log into the wireless network, follow these steps:
1. Make sure you are connected to the "DTC Wireless" network. Some network cards will automatically search for all local network and allow you to select from a list, others will require that you manually set the SSID to "DTC Wireless".
2. Open a web browser and go to any web site. Note: Pop-up windows must be enabled to maintain network connectivity.
3. The web browser will be redirected to a login page. Enter the username and password that was provided by DTC staff and click the login button.
4. If authentication is successful, the web browser will go to the original desired web site and a small authentication window will open. This small window may then be minimized if desired until the user is ready to logout.
5. When ready to logout, go to the small authentication window, and click logout.
Please notify help@dtc.umn.edu of any problems with the wireless network.

For University of Minnesota Students, Faculty, and Staff:

The campus-wide University of Minnesota wireless network is available at the Digital Technology Center. Use of the University's VPN service to keep wireless traffic private is recommended. More information on obtaining the VPN client can be found here:

A multi-platform guide about connecting to the U of M wireless can be found at the following website:

Office Network Access

The Digital Technology Center provides wired network connectivity in all office and conference rooms. It is expected that any computer connected to the network maintain relatively current versions of all OS, service, and application security patches. All non-necessary services such as telnet and ftp should be turned off.

There will be periodic scans of the machines for security problems. Workstation maintainers are expected to correct the problems that are identified. Any machines that are compromised or cause problems will be disconnected from the network.

To connect a workstation to the network, please e-mail the desired machine name, OS version, the office network jack to be activated (i.e. 593 AB), and who will be managing the workstation to help@dtc.umn.edu. The DTC staff will then issue the IP address information.
Any office network ports that are unused for 60 days may be deactivated.
Any special networking needs should be directed to help@dtc.umn.edu.

AirProjecter in Walter 405

The AirProjector in Walter 405 allows a Windows laptop with a wireless ethernet card (802.11b) to connect to the projector without a wired connection. It works well for presentations and demonstrations but is not adequate for displaying video.

Using the AirProjector

Verify that you have an 802.11b wireless ethernet card. If you are able to connect to the U of M wireless network or the DTC's wireless network, your card should work fine. The DTC does not have spare wireless cards available.
If you need wireless internet access during your presentation or to download the AirProjector client software in the next step, you will need a DTC Wireless account. If you do not already have an account, send an email to help@dtc.umn.edu with your email address (or U of M X500 account), and the duration of your stay.
Download and install the latest version of the AirProjector Client software from http://www.komatsu.com/el/lan/ap_download.html#2. To install the software, open the downloaded file and double-click on "Setup.exe". An installation wizard will walk you through the rest of the process.
Make sure you are connected to the "DTC Wireless" network.
Double click on the "AirProjector Client" icon. When it has finished searching for available projectors, click on the projector labeled "Walter 405" and click the triangular "Play" button.
When you're done, click the rectangular "Stop" button.

Technical Support

Any questions or concerns regarding network issues should be sent to help@dtc.umn.edu.
