OKI OkiLAN 6010e User’s Guide
RARP or BOOTP
If an IP address has not been permanently assigned, the
OkiLAN 6010e will use Reverse Address Resolution
Protocol (RARP) or Bootstrap Protocol (BOOTP). The
OkiLAN 6010e will broadcast requests for its IP ad-
dress to both RARP and BOOTP servers. A RARP or
BOOTP server will respond by searching a configura-
tion file that maps the Ethernet hardware addresses of
devices on the network to their respective IP addresses.
If a match is found, the server’s response will include
the IP address of the device.
Most UNIX operating systems support either the RARP
or BOOTP protocol. To find out which protocol your
operating system supports, request the manual page for
the protocol’s daemon (e.g. man bootpd or man rarpd),
or see your network manuals. Both protocols require
that you add the product’s network hardware address
and IP address to a configuration file. See your network
documentation for instructions or refer to Appendix B,
Application Considerations.
Note: An IP address received from a RARP or BOOTP
server is not permanently programmed into the
OkiLAN 6010e. Therefore, if you choose this method
of assigning the IP address, the RARP or BOOTP
server must be available every time the OkiLAN 6010e
is powered on or reset. The IP address can be stored
permanently using telnet, OkiNet for TCP/IP or OkiNet
for NetWare.
A Winsock compliant BOOTP server is located on the
OkiNet disk. This has been provided for users who do
not have UNIX machines.
