# Sample udhcpd configuration file (/etc/udhcpd.conf)
# Values shown are defaults

# The start and end of the IP lease block
start           192.168.43.20
end             192.168.43.254

# The interface that udhcpd will use
interface        wlan0
# The maximim number of leases (includes addresses reserved
# by OFFER‘s, DECLINE‘s, and ARP conficts). Will be corrected
# if it‘s bigger than IP lease block, but it ok to make it
# smaller than lease block.
#max_leases     254

# 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

# The amount of time that an IP will be reserved (leased to nobody)
# if a DHCP decline message is received (seconds).
#decline_time   3600

# The amount of time that an IP will be reserved
# if an ARP conflct occurs (seconds).
#conflict_time  3600

# How long an offered address is reserved (seconds).
#offer_time     60

# If client asks for lease below this value, it will be rounded up
# to this value (seconds).
#min_lease      60

# The location of the leases file
#lease_file     /var/lib/misc/udhcpd.leases

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

# Everytime udhcpd writes a leases file, the below script will be called.
#notify_file                    # default: no script
#notify_file    dumpleases      # useful for debugging

# The following are bootp specific options, settable 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‘.
# Examples:
opt     dns     192.168.10.2 192.168.10.10
option  subnet  255.255.255.0
opt     router  192.168.10.2
opt     wins    192.168.10.10
option  dns     129.219.13.81   # appened to above DNS servers for a total of 3
option  domain  local
option  lease   864000          # 10 days of seconds
