### TCP/IP Protocol Stack Setup

Use this procedure to configure TCP/IP parameters for the PortServers in your network.

#### Procedure

1. Verify the TCP/IP protocol stack module:

   RealPort requires that the TCP/IP protocol stack be running on the NetWare Asynchronous I/O (AIO) server. To verify that the TCP/IP protocol stack is loaded, type the following command at the NetWare System Console:

   <servername>:modules tcpip

   If the TCP/IP stack is loaded, the OS returns information about the module.

   ##### Example

       STAN:modules tcpip
       TCPIP.NLM       (Address Space = OS)
         Novell TCP/IP Module NW5SP3.240699
         Version 5.21a    July 1, 1999

       STAN:

2. Add IP information to the HOSTS file:

   The AIO driver uses the SYS:\ETC\HOSTS file to find network PortServers. You must edit the SYS:\ETC\HOSTS file to add the DNS name and IP address of each PortServer in the network.

   The IP address mask should be set to appropriate values as determined by your network class.

   ##### Example

         NetWare Text Editor  4.15                 NetWare Loadable Module

                            Current File "SYS:\ETC\HOSTS"
       #
       #    Mappings of host names and host aliases to IP address.
       #
       127.0.0.1        loopback lb localhost    # normal loopback address

3. Add IP information to each PortServer configuration:

   You must also set the DNS name and IP address in the configuration of each corresponding PortServer (see Configuring the PortServer for RealPort).
