If the Open Transport software is not already installed, run the installer script and, unless you only wish to install certain components, choose the Easy Install. Apply upgrade patches according to the documentation that accompanies them.
Detailed instructions are on the following pages.
Please note that the screen captures and descriptions in this document are based on Open Transport release 1.0.7. The screens and requested input in later versions may be slightly different than that described in this document. If you installed Open Transport on a Mac that already had MacTCP or AdminTCP installed and correctly configured, your MacTCP settings will be used and shouldn't require any adjustments. The method you choose will depend on your network connection type. If the Mac accesses the network with some other type of connection, such as a PPP connection over a modem, you may see additional options in the pull-down menu.
