attempted BOOTP request. 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 work- station. If bootpd is not running on a workstation, type man bootpd at the UNIX prompt to consult a manual page on the BOOTP daemon and how to start it.

Limitations

Often TCP/IP networks are divided into subnets. BOOTP does not work across subnets. When install- ing a Network Print Server, make sure the following criteria are met for BOOTP to work properly.

Both the BOOTP server and the Network Print Server are physically attached to the same subnet.

The IP address assigned to the Network Print Server and the IP address of the BOOTP server belong to the same subnet. OR

Your router(s) are configured to forward BOOTP packets between the Network Print Server’s subnet and the subnet of the host running the BOOTP server.

Configuring the Network Print Server IP Address with RARP

RARP is an acronym for Reverse Address Resolution Protocol. Every TCP/IP network device must have a unique 32-bit IP address. TCP/IP network devices will have both an IP address and a 48-bit Ethernet (net- work hardware) address. Ethernet addresses usually cannot be configured and are hard coded by the man- ufacturer of the device. RARP is a protocol used by devices that know their network hardware address, but
