Getting the LAN port up and running

First step for IPX or IP/IPX networks

If your network uses the IPX protocol, you must enter the IPX network number of the segment the NETServer connected to the NETServer’s LAN port. You can find this network number using Novell’s CONFIG utility.

For File Servers Running Novell Version 3.xx

1.Go to the console of a file server that is on the same network segment that the NETServer is on.

2.From Novell’s Console program press CTRL-ESC, then ESC, until the : (colon) prompt appears. Select System Console and press the Enter key.

3.Type the following:

CONFIG Enter

A display similar to the one shown below appears:

File server name: USR_SERVER_ONE

IPX internal network number: 0000000A
