OkiLAN 6200e Plus User's Guide the colons between each byte. The ip part of the entry is where the IP address is specified. There are several other parameters that can be specified in a bootptab entry. However, the three parameters shown here are the only ones required for Network Print Server installation. The following sequence of events occurs during the power up of the Network Print Server using BOOTP. 1. A Network Print Server powers up but does not know its IP address. (It does know its network hardware address.) 2. The Network Print Server sends out a BOOTP request packet with its network hardware address. For this example, the network hardware address is 00:40:68:17:50:A4. 3. The bootpd daemon running on a BOOTP server (which in this example is a UNIX workstation) sees the BOOTP request along with the network hardware address. It looks up the network hardware address in the "/etc/bootptab" file. The bootpd daemon finds the associated IP address of the device in the bootptab file. 4. The bootpd daemon transmits a response to the Network Print Server with the IP address 192.168.42.55. The Network Print Server uses this IP address for all subsequent transmissions. For these steps to work properly, at least one BOOTP daemon (bootpd) must be running on the BOOTP server. To test whether a BOOTP daemon is running on the BOOTP server, use the ps command with the show all process option within fifteen minutes of an TCP/IP 140
