# 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 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 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 leases file
#lease_file /var/lib/misc/udhcpd.leases
# The location of the pid file
#pidfile /var/run/udhcpd.pid
# 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
#siaddr 192.168.0.22 #default: 0.0.0.0
#sname zorak #default: none
#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. 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 # appended to above DNS servers for a total of 3
option domain local
option lease 864000 # 10 days
# Currently supported options (for more info, see options.c):
#opt lease NUM
#opt subnet IP
#opt broadcast IP
#opt router IP_LIST
#opt ipttl NUM
#opt mtu NUM
#opt hostname STRING - client's hostname
#opt domain STRING - client's domain name
#opt search STRING_LIST - search domains
#opt nisdomain STRING
#opt timezone NUM - (localtime - UTC_time) in seconds. signed
#opt tftp STRING - TFTP server name
#opt bootfile STRING - file (kernel image) to load for booting
#opt bootsize NUM - size of that file
#opt rootpath STRING - (NFS) path to mount as root fs
#opt wpad STRING
#opt serverid IP - by default, server's IP
#opt message STRING - error message (udhcpd sends it on success too)
# Options specifying server(s)
#opt dns IP_LIST
#opt wins IP_LIST
#opt nissrv IP_LIST
#opt ntpsrv IP_LIST
#opt lprsrv IP_LIST
#opt swapsrv IP
# Obsolete options, no longer supported
#opt logsrv IP_LIST - 704/UDP log server (not syslog!)
#opt namesrv IP_LIST - IEN 116 name server, obsolete (August 1979!!!)
#opt cookiesrv IP_LIST - RFC 865 "quote of the day" server, rarely (never?) used
