Ethernet connections with Open Transport for Macintosh
| View PDF Version
These instructions detail using Open Transport to connect to the
University of Minnesota ethernet backbone. You should contact your network
administrator before you start to make certain that your networking information
is correct.
Before you begin...
You should have the following items and information handy before you
start installing and configuring software:
- Your system software disks or CD
- Your network configuration information: IP address, subnet mask, gateway/router
address. If you don't have this information, contact your network administrator
or contact NTS to find this information.
- Confirmation that your etherjack is active (contact NTS or your network administrator for this).
- Your Internet ID and password. Your central University Internet ID/password
are obtainable from ADCS. Departmental usernames and passwords
should be obtained from your network administrator.
Installing Open Transport
You will have better results if you use a current version of Open
Transport (1.1.2). You can check to see if you have Open Transport
installed, and the version you have installed by following these steps:
- Go to the Apple menu, choose Control Panels, and look
for control panels named AppleTalk and TCP/IP.
- If you do not see AppleTalk or TCP/IP, but do
see Networking or MacTCP, then you don't have OT but "classic"
networking. You will need to upgade your OS to at least 7.6.1.
- If you see AppleTalk or TCP/IP, open one of them, go
to the File menu and choose Get Info. Your version of
OT should be 1.1.2 or later. If you have an earlier version,
see below to install OT.
If you need to install OT, read on. If you don't, you can jump
to the section on configuring AppleTalk or TCP/IP.
- Download the latest version of OT directly from Apple.
You may have the option to download the Net Install version of OT to get the full installer all at once,
or to download OT in smaller, separate pieces if you have a slow or unreliable Internet connection.
- Before installing OT on your Mac, you should remove any vestiges
of the MacTCP and Networking control panels from your
System folder and restart your computer.
- Insert the first OT disk (or open the OT network installtion
folder), and double-click the installer. Follow the prompts to install
OT. You will have to restart your machine when the installation
is finished.
Configuring AppleTalk
AppleTalk allows you to access other Macintosh computers
and network servers via the Chooser.
- Open the AppleTalk control panel.
- Set Connect via: to Ethernet.
- Select the appropriate AppleTalk zone for the Current zone
value (consult your network administrator if you are unsure of what
this should be).
- Close the AppleTalk control panel by clicking the close box
in the upper left-hand corner of the window. Click the Save button
when asked if you want to save the current configuration.
Configuring TCP/IP
If you use DHCP in your department or are in University Housing
then go on to the Macintosh DHCP Configuration
Guide.
- Open the TCP/IP control panel.
- Set Connect via: to Ethernet, and Configure:
to Manually (consult your network administrator, in case your
network is set up to obtain the IP address via BootP or DHCP).
- Enter your IP address in the IP Address field.
- Enter your subnet mask in the Subnet mask field.
- Enter your gateway/router address in the Router address field.
- Enter 128.101.101.101 and 134.84.84.84
in the Name server addr box.
- Enter umn.edu and tc.umn.edu in the
Search domains box.
- Close the TCP/IP window, and it will ask you if you want to
save the current configuration, select the Save button.
You should now be able to access the Internet using any Internet application
(e.g., Netscape, Internet Explorer, SSH).
