If you haven't installed the appropriate driver software for your Ethernet adapter, do so now. Descriptions to perform this task is beyond the scope of this document.
Open the MacTCP control panel. Select the appropriate network driver (Ethernet, NOT EtherTalk) and click on the 'More...' button.
Under 'Obtain Address:', click 'Manually'.
Under 'IP Address:', select class C from the popup menu. Ignore the rest of the dialog box sections.
Fill in the appropriate information under 'Domain Name Server Information:'.
Under 'Gateway Address:', enter 192.168.0.1
Click 'OK' to save the settings. In the main window of the MacTCP control panel, enter the IP address of your Mac (192.168.0.x, 1 < x < 255) in the 'IP Address:' box.
Close the MacTCP control panel. If a dialog box pops up, notifying you to do so, then restart the system.
You may optionally ping the Linux box to test the network connection. If you have the freeware program MacTCP Watcher , click on the 'Ping' button, and enter the address of your Linux box (192.168.0.1) in the dialog window that pops up. (This is only an INTERNAL LAN connection test, you can't ping the outside world yet.) If you don't see "replies" to your PINGs, please verify your network configuration.
You can optionally create a Hosts file in your System Folder so that you can use the hostnames of the machines on your LAN. The file should already exist in your System Folder, and should contain some (commented-out) sample entries which you can modify according to your needs.
