# 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

# NOTE: "boot_file FILE" and "opt bootfile FILE" are conceptually the same,
# but "boot_file" goes into BOOTP-defined fixed-size field in the packet,
# whereas "opt bootfile" goes into DHCP option 0x43.
# Same for "sname HOST" and "opt tftp HOST".

# 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
