Configuring Open Transport

The following are instructions for configuring Open Transport to work with ethernet at Stanford University. To follow these instructions you should already have a Leland account, an ethernet card, and Open Transport software installed on your Macintosh computer. Your computer must have already been registered by MedISG for these directions to have any effect (Register my computer with MedISG).

Configuring OT

From the "Control Panels" option in the Apple menu, select the "TCP/IP" control panel.


System 8.5.x

For the "Connect Via:" field: Click and hold on the menu, then choose "Ethernet", "Build-in Ethernet", or the name of your ethernet PC Card (only one of these choices will appear per computer).

For the "Configure:" field: click and hold on this menu, then choose "Using DHCP Server".

Your window should look exactly like the one in the picture above. You can add "Stanford.edu" to the "Search domains:" field but this is usually unnecessary.

You can now choose "Close" from the "File" menu. When prompted to save changes to the current configuration, click on the "Save" button.

System 8.0 or 8.1 users will see a slightly different TCP/IP Control Panel window:


System 8.0, 8.1

For Systems 8.0, 8.1, and 7.6.x Open Transport TCP/IP, enter the values into the fields as shown above. A notable exception is the "Router address:" field. Biochemistry uses four routers total:
171.65.19.1
171.65.20.1
171.65.21.1
171.65.22.1

Check the TCP/IP configuration on a neighboring computer to determine it's IP and router address. Enter the router address from the neighboring computer into your computer's "Router address:" field in the TCP/IP control panel.

Using DHCP

Unlike the modem dial-in internet connection, DHCP does not require you to make a connection before use. You may simply load an application (such as Fetch, Netscape, Eudora, or Telnet) and Open Transport will automatically open the TCP/IP connection.

If you are using DHCP with a laptop, no special steps are necessary to disconnect DHCP.


Getting Additional Help

If you have difficulty with any aspect of getting or using OT/PPP, your best source of help is Stanford's su.computers.dialin newsgroup, the main forum for the exchange of data about PPP and other areas of our dial-in service. You can use this newsgroup to ask and answer questions, tell others of useful solutions you have discovered, and find out about any new or upgraded services being offered. There are many different ways to read and post messages to the newsgroup.

An alternate way to submit a query is to send electronic mail messages to su-computers-dialin@news.stanford.edu, which will forward your messages to the newsgroup. As always, include your electronic mail address so responses can, if you wish, be sent directly to you.

You can also contact ITSS Customer Assistance via HelpSU for consulting help.

Apple's Web site also contains helpful tips for troubleshooting Open Transport.

For additional help, contact your dormitory's Resident Computer Coordinator (RCC) or your department's Local Network Administrator (LNA).
