TOPIC


    I am trying to launch Netscape or any TCP/IP application on my computer and I get this message, "That pesky MacTCP is acting up again." What does this mean?

DISCUSSION


    What does "That pesky MacTCP is acting up again." Message Mean?
    • The PPP/SLIP software is not successfully connecting to your Internet Service Provider (ISP).
    The PPP extension and Config PPP control panel have to be installed, or the appropriate SLIP software. You need to verify that a modem connection is made to your ISP before launching a TCP/IP application. You should launch Config PPP or Config SLIP and dial out through that software.
    - Confirmation messages from the connection software will show when a successful connection is made,
    - Or error messages will indicate what is wrong.
    • The MacTCP or TCP/IP control panel is not configured correctly.
    See the "Correct MacTCP or TCP/IP Configuration Setup" section below for more information.
    • The MacIP server is down or does not have an available IP address.
    You should select a different zone that also has a MacIP server on the network. This is selected under the EtherTalk or LocalTalk icon's pop-up menu in the MacTCP control panel.
    • The Internet Gateway or Router is down or the address is entered incorrectly (this usually applies in manual IP configurations).
    You have to ask your network administrator for a list of valid Internet Gateway or Router IP addresses.
    • The MacTCP or TCP/IP files are corrupt.
    If you are using MacTCP, throw the MacTCP control panel, MacTCP DNR, and MacTCP Prep files into the trash.

    - Reinstall MacTCP with a custom installation from the Mac OS 7.5 installer, or drag-copy from previous system versions. You will have to enter all necessary information in the control panel.

    If you are using Open Transport and TCP/IP, throw the TCP/IP control panel and TCP/IP Preference files into the trash.

    - Reinstall the TCP/IP control panel with a custom installation from the Mac OS 7.5.2 or higher installer. Once at the Custom Install choices, extend Networking, extend Open Transport, and choose TCP/IP. You will have to enter all necessary information in the control panel.

    MacSLIP or other SLIP software connection
    The procedures are the same as for MacPPP or FreePPP.

    MacIP Server connection

    Classic AppleTalk
      1. Open the MacTCP control panel
      2. Select EtherTalk (on an Ethernet network) or LocalTalk (on a LocalTalk network or ARA (Apple Remote Access) connection) icon.
      3. From the pop up menu below the correct icon, select the zone that has a MacIP server, the network administrator will provide this information.

      2. Select Connect via: AppleTalk (MacIP)
      3. Select Configure via:
      a) Using MacIP Server, when using server assigned address
      - Select MacIP Server Zone: the network administrator will provide this information.
      - Enter Search domains: the network administrator will provide this information.
      b) Using MacIP Manually - when using manually assigned address that the server manages Select MacIP Server Zone: the Net
    Admin will provide this info. The Net Admin will provide and the customer will enter: IP Address, Router address, Name
    server addr, and Search domains.

    Manual IP Address connection

    Classic AppleTalk
