Section 4 - Appendix B - Application Considerations 4. The rarpd then consults the "/etc/hosts" file and looks up the name OKIPRINTER. It finds an IP address (in this case 192.168.42.55) associated with the name OKIPRINTER. 5. The rarpd daemon transmits a response to the OkiLAN 6020e with the IP address 192.168.42.55. The OkiLAN 6020e will then use this IP address for all subsequent transmissions. For all these steps to work properly, at least one RARP daemon (rarpd) must be running on the RARP server. On most UNIX systems, this can be tested by using the ps command with the show all processes option. Unfortunately, the ps options differ from one UNIX workstation to another. Perform a man ps at the UNIX prompt to consult a manual page on the ps command for a particular workstation. If rarpd is not running on a workstation, type man rarpd at the UNIX prompt to consult a manual page on the RARP daemon and how to start it. Limitations Often TCP/IP networks are divided into subnets. RARP does not work across subnets. When installing an OkiLAN 6020e, make sure the following two criteria are met for RARP to work properly. 1. Both the RARP server and the OkiLAN 6020e are physically attached to the same subnet. 2. The IP address assigned to the OkiLAN 6020e and the IP address of the RARP server belong to the same subnet. IV - 62 OKI OkiLAN 6020e User's Guide
