busybox最新版的源码:学习和应用的好东东,多的不说了,大家看后再说吧

# Sample udhcpd configuration file (/etc/udhcpd.conf)

# The start and end of the IP lease block

start 		192.168.0.20	#default: 192.168.0.20
end		192.168.0.254	#default: 192.168.0.254


# The interface that udhcpd will use

interface	eth0		#default: eth0


# The maximim number of leases (includes addressesd reserved
# by OFFER's, DECLINE's, and ARP conficts

#max_leases	254		#default: 254


# If remaining is true (default), udhcpd will store the time
# remaining for each lease in the udhcpd leases file. This is
# for embedded systems that cannot keep time between reboots.
# If you set remaining to no, the absolute time that the lease
# expires at will be stored in the dhcpd.leases file.

#remaining	yes		#default: yes


# The time period at which udhcpd will write out a dhcpd.leases
# file. If this is 0, udhcpd will never automatically write a
# lease file. (specified in seconds)

#auto_time	7200		#default: 7200 (2 hours)


# The amount of time that an IP will be reserved (leased) for if a
# DHCP decline message is received (seconds).

#decline_time	3600		#default: 3600 (1 hour)


# The amount of time that an IP will be reserved (leased) for if an
# ARP conflct occurs. (seconds

#conflict_time	3600		#default: 3600 (1 hour)


# How long an offered address is reserved (leased) in seconds

#offer_time	60		#default: 60 (1 minute)

# If a lease to be given is below this value, the full lease time is
# instead used (seconds).

#min_lease	60		#defult: 60


# The location of the leases file

#lease_file	/var/lib/misc/udhcpd.leases	#defualt: /var/lib/misc/udhcpd.leases

# The location of the pid file
#pidfile	/var/run/udhcpd.pid	#default: /var/run/udhcpd.pid

# Everytime udhcpd writes a leases file, the below script will be called.
# Useful for writing the lease file to flash every few hours.

#notify_file				#default: (no script)

#notify_file	dumpleases 	# <--- useful for debugging

# The following are bootp specific options, setable by udhcpd.

#siaddr		192.168.0.22		#default: 0.0.0.0

#sname		zorak			#default: (none)

#boot_file	/var/nfs_root		#default: (none)

# The remainer of options are DHCP options and can be specifed with the
# keyword 'opt' or 'option'. If an option can take multiple items, such
# as the dns option, they can be listed on the same line, or multiple
# lines. The only option with a default is 'lease'.
