TOPIC

    If more than one network interface (Ethernet port) has been defined, TCP/IP and AppleTalk services become unavailable.

DISCUSSION

    Symptom

    TCP/IP and AppleTalk services do not work in the Classic environment.

    Products affected
    • Mac OS X Public Beta
    • Computers that have more than one Ethernet port (network interface)

    Note: Other kinds of network interface, such as AirPort cards, do not work with Mac OS X Public Beta. Some Apple-branded Ethernet cards manufactured for use on computers that do not meet the Mac OS X Public Beta system requirements may not be recognized by Mac OS X Public Beta.

    Solution

    This is a normal limitation of Mac OS X Public Beta, which Apple may address in a future software version.

    Follow these steps to use one network interface for all of your network services.
      1. Open the System Preferences application.

      2. Click Network.

      3. Click TCP/IP.

      4. Determine whether you have one or more network interfaces.
      If you only have one, the pop-up menu under the TCP/IP tab will be Configure. If you have two or more, the pop-up menu under the TCP/IP tab will be Show.

      5. Click the lock to make changes.

      6. Enter the name and password of an administrative user.



    If your computer has two or more network interfaces:
      1. Choose TCP/IP from the Show menu.

      2. In the left column, click Global TCP/IP.

      3. Verify Global settings.
      In the right column, make sure your settings are correct for your network. If in doubt, see your network administrator or your Internet service provider.

      4. Choose one interface to use.
      Below Global TCP/IP in the left column, the names of network interfaces appear, such as "Built-in Ethernet Port" or "Ethernet Card Port 1." It is recommended but not required that you use an Apple Built-in Ethernet Port and disable services on the added device when using Mac OS X Public Beta.

      5. Click the name of the interface you have chosen.

      6. Set up the interface you chose.
      This interface may already be properly configured for your network. If not, choose Using BootP, Using DHCP, or Manually from the Configure pop-up menu. Make choices appropriate for your network. If in doubt, see your network administrator or Internet service provider.

      7. Click the name of the interface to be disabled.

      8. Choose No Connection from the Configure pop-up menu.

      9. Click the AppleTalk tab.

      10. Make sure that "AppleTalk active" is checked.

      11. Check the name of the chosen port.

      12. Uncheck the name of the port to be disabled.

      13. Click Apply.

      14. Restart the computer.



    If your computer has only one network interface:

    This particular issue does not affect your computer. Try normal network troubleshooting, which might include:
    • Starting up your computer from Mac OS 9. Does the same network failure occur?
    • Checking your TCP/IP settings in the Network pane of the System Preferences application.
    • Checking your physical network connections and cabling.
    • Checking for service outage on your network or with your Internet service provider.
