Sample dhcptab File

The following sample dhcptab file will supply DHCP options to a variety of clients on a network. Some options are common to all clients. Other options are specific to clients attached to the server; to classes of JavaStation clients; or to specific JavaStation machines. Note that dhcptab can serve many different clients, not just JavaStation computers.

# /var/dhcp/dhcptab
#
# This file is a sample DHCP server configuration database for 
# JavaStation clients.
#
# Refer to dhcptab(4) for details. This table is generated by
# using the dhcpconfig(1M) command in conjunction with the
# dhtadm(1M) command. It can be administered with the dhtadm
# command.

# The following are symbol definitions for the Vendor-Specific 
# Options. JOScmd1-4 can be used in macros that set JavaOS
# properties. JOSchksm is the JavaOS checksum. Refer to the
# dhcptab(4) man page for symbol definition syntax. 

JOScmd1				s		Vendor=SUNW.JSIIep SUNW.JDM1,101,ASCII,1,0
JOScmd2				s 		Vendor=SUNW.JSIIep SUNW.JDM1,102,ASCII,1,0
JOScmd3				s 		Vendor=SUNW.JSIIep SUNW.JDM1,103,ASCII,1,0
JOScmd4				s 		Vendor=SUNW.JSIIep SUNW.JDM1,104,ASCII,1,0

JOSchksm 				s 		Vendor=SUNW.JSIIep,128,NUMBER,4,1

# Standard macros generated when configured with dhcpconfig(1M). # The first is the time offset from GMT (UTC) time, the second
# applies to all clients serviced by this server, and the third
# applies to all clients attached to one of the nets attached to
# the server.

# The macros below contain individual DHCP options for the two
