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

# The start and end of the IP lease block
start  192.168.0.20
end  192.168.0.254

# The interface that udhcpd will use
interface eth0
# The maximum number of leases (includes addresses reserved
# by OFFER's, DECLINE's, and ARP conflicts). 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 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 conflict 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 pid file
#pidfile /var/run/udhcpd.pid

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

# The time period at which udhcpd will write out leases file.
# If this is 0, udhcpd will never automatically write leases file.
# Specified in seconds.
#auto_time 7200

# Every time 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
# next server to use in bootstrap
#siaddr  192.168.0.22 # default: 0.0.0.0 (none)
# tftp server name
#sname  zorak  # default: none
# tftp file to download (e.g. kernel image)
#boot_file /var/nfs_root # default: none

# Static leases map
#static_lease 00:60:08:11:CE:4E 192.168.0.54
#static_lease 00:60:08:11:CE:3E 192.168.0.44

# The remainder of options are DHCP options and can be specified 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.
# 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 # appended to above DNS servers for a total of 3
option domain local
option lease 864000  # default: 10 days
option msstaticroutes 10.0.0.0/8 10.127.0.1  # single static route
option staticroutes 10.0.0.0/8 10.127.0.1, 10.11.12.0/24 10.11.12.1
# Arbitrary option in hex form:
option 0x08 01020304 # option 8: "cookie server IP addr: 1.2.3.4"
