A name can be arbitrarily assigned to any device on a network. The following examples use the name OKIPRINTER. Remember that this name is arbitrary; a customer can assign any name they wish.
/etc/bootptab: The “/etc/bootptab” file has entries where each entry maps a network hardware address to an IP address.
Example: OKIPRINTER:\ ht=ether:\ ha=0040681750A4:\ ip=192.168.42.55
The ht signifies hardware type. For the OkiLAN 6100e+, it will always be ether for an Ethernet device and token for a
The following sequence of events occurs during the power up of the OkiLAN 6100e+ using BOOTP.
1.An OkiLAN 6100e+ powers up but does not know its IP address. (It does know its network hardware address.)
2.The OkiLAN 6100e+ 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.
