# DESCRIPTION:
#
# This is a template server.pcy file. A particular site may need to make
# modifications to this, especially to the name service and name allocation
# policies in force

# Default time-to-live for an address lease if not specified on a
# per host, per subnet or per class basis.

default_ttl 86400

# Time to live on provisional list

provisional_ttl 60

# Size of the internal array specifying the number of address
# blocks held on the free list. This number should not be too
# high, or the server will "forget" about all previous allocations
# of expired leases very quickly. It should not be too low or
# performance will suffer.

free_list_size 8

# Define type of name service. The name service is one of
# { dns, local, nis, nis+}.
# local means use text files on the local system (i.e. /etc/hosts).

# On OpenVMS leave this option as "dns".

name_service dns

# Specify whether the name service is dynamically updateable.
# NIS and NIS+ are dynamically updateable, but the system
# administrator may choose to disable this capability. In
# both cases the server must be in the same domain as the
# name server, and the JOIN server's key must be in the
# publickey database. NIS also requires the creation of
# a pseudo map, "join", and the installation of the file
# "updaters" in /var/yp on the name server. See manual
# for further details. This option can be enabled for DNS.
# The default is not to permit dynamic updating.

#name_service_updateable

# Name policy
# The name may be choosen according to three possible policies:
#   assign_name_by_hwaddr:
#       A particular client (identified # by its hardware address)
#       always has the same name wherever possible. This option
#       may only be choosen if the name service is updateable.
#   assign_name_by_ipaddr:
#       The client gets a name from the IP address which was
#       assigned to it, as found in the name service. This
#       option is incompatible with assign_name_by_hwaddr.
#   accept_client_name:
#       This toggle is valid only when the policy is
#       assign_name_by_hwaddr. When "on" the server will use
#       the name suggested by the client and bind it to the
#       IP address delivered by the DHCP protocol. This is
#       true even if the client in question already has a name
#       in the server's DB which is not the name suggested.
#       The old name continues to be "owned" by the client
#       and may have a valid IP address bound to it.
#       When this toggle is "off" the server will return to
#       client a pre-existing name bound to the client identifier
#       or hardware address, regardless of the name the client
#       suggests to the server.
#
# If no name can be found by the application of one or more of
# these policies, the server will generate a name for the domain
# by using the name prefix in the "namepool" database.

assign_name_by_ipaddr

#
# Note: The following two settings are most appropriate when you are using
# dynamic DNS updates. To set this up on the DHCP server side uncomment these
# lines and delete the line above with "assign_name_by_ipaddr".
#assign_name_by_hwaddr
#accept_client_name

# When the naming policy is assign_name_by_hwaddr the server will
# not allow a client to use a name which is "owned" by some other
# client. I.e. A name that is already bound to a different Client
# identifier or MAC address. When this toggle is on, this prohibition
# is lifted and the name will be re-assigned

#ignore_name_owner


# Bootp.
# Remove this line if the server is not to support old-style Bootp

support_bootp


#This boolean is only valid if Bootp clients are supported
#(support_bootp option is enabled). When present it permits
#the server to permanently assign an IP address from its
#free pool to a BOOTP client in the event that no permanent
#binding exists in dhcpcap. Normally the JOIN server can
#only service BOOTP clients for which such a binding pre-exists.

#bootp_addr_from_pool


# Timeout value for ping in milliseconds. Before the server offers an
# address it pings (using ICMP echo) it: if a reply is received the
# server assumes that it is in use and makes another choice. "ping_timeout"
# is the number of milliseconds the server will wait for a reply.

ping_timeout 500

# Registered clients. When this flags in on DHCP service will only be
# granted to clients which have been pre-registered in the JOIN database.
# To pre-register a client used jdbreg or xjdbreg. This feature is only
# available starting in release 2.3

#registered_clients_only


# Instructs the server to check whether or not the dhcpcap file appears to
# have changed each and every time a client configuration is required.
# If the file has changed (as indicated by its time stamp), the server
# will read and parse it anew.

auto_reread

# Before a BOOTP client is given a hard-wired IP address the server checks
# that the client is indeed connected to the logical IP network for which
# the address is valid. If not an error is logged and no response sent.
# In order for this to work properly the netmasks file must contain the
# network numbers and masks for any non-standard IP Class A, B or C
# configuration.


#check_bootp_client_net


# Before an IP address is given to a BOOTP client the server first checks
# to see whether or not it is in use by sending an ICMP echo. If a reply
# is received an error is logged.  If the address was from the dynamic pool
# it will be marked un-available, and a new address selected from the pool.
# If the address was statically configured the server refuses to configure
# the client.

#ping_bootp_clients


# The server will by default ignore any packets forwarded to it via a relay
# agent whose giaddr field shows it to be directly connected to the server -
# the server will, presumably, hear the clients broadcast directly. This
# option forces the server to reply regardless.

#reply_to_relay_on_local_net


# The server will not send a complete configuration to a DHCP client unless
# this toggle is set. Resolving a client configuration can be time consuming
# and, in a multi-server environment, the client may select another server.

#send_options_in_offer

# Minimum packet size for DHCP requests.  By modifying this parameter,
# the DHCP server can be configured to work with some non-compliant
# DHCP clients that send DHCP requests smaller than the minimum required
# packet length.  By default, the minimum packet size is 300 bytes.

minimum_bootp_packet_size 300

# Set this true if you want to automatically delete leases when
# the client changes its net. I.e. if the server has leases for
# the client on several nets, and the client boots on a specific
# net, say X, the all the leases on all the nets except X, whether
# expired or not will be deleted.
#
# Note that some HW, notably SUN workstations, use a MAC address
# or client identifier which is the same regardless of the
# interface being configured. Therefore, two interfaces of a client
# of this tupe may appear to the server to be a single client
# which has changed network. You would probably not want to
# auto delete leases in this case.

#auto_release

# Finite Bootp lease support. When this parameter is non-zero it
# instructs the server to grant FINITE leases to BOOTP clients.
# BOOTP clients don't know this, so before the server can re-use
# these leases it must ping the IP address. If a reply is heard
# the server automatically extends the lease by this time interval (secs).
# Note that the *original* lease conferred on a BOOTP client is
# determined by the dhcpcap file, which need not be the same as
# this extension. Also that this capability is only relevant to
# BOOTP clients which are dynamically addresses (bootp_addr_from_pool
# toggle on).

bp_auto_extension 0

# Set auto_sync_dbs to flush the server database to disk
# after each update. This is more reliable in the event
# of a failure, but slows the server down.

auto_sync_dbs

# This toggle is used to ignore the so-called client ID
# and instead always use the MAC address to identify
# the client. It is useful to turn this on if you are
# trying to migrate clients either from BOOTP or from
# a vendor stack which doesn't set the ID to one
# which does.

#use_macaddr_as_id

# Turn on if you want to support Microsoft's Proxy Remote Access Server
# (RAS). The RAS server generates a BOOTP packet with a MAC address
# of 16 octets. JOIN recognizes these packets and will ignore them
# (and complain about them in the log) unless this toggle is on.

# This option is not currently supported on OpenVMS.

#support_microsoft_ras

# Turn on if you are using Token Ring Source Routing
# Currently this is only supported on HPUX platforms.
#tr_source_routing

# Use canonical_name to override the default (which will
# normally be the value returned by "gethostname". This is
# primarily for multihomed hosts which have the
# canonical name corresponding to an interface which
# is ignored by JOIN (e.g. ATM interfaces).
# and for high-availability servers which have per-service
# IP addresses which differ from any "physical" ip host address

#canonical_name glenroy

# Expand the BOOTP reply packet to 548 bytes (BOOTP clients only).
# Normally joind replies with a packet of 300 octets (the legal minimum),
# or a size equal to the size of the packet received, whichever is
# the bigger. Setting this parameter on causes all replies to BOOTP
# clients to be 548 octets. (These sizes are exclusive of the UDP (8)
# IP (20, usually)  and LINK LAYER (14 of 10MBPS ethernet) headers

#expand_bootp_packet

# Dynamically created name to IP mappings in the DNS are normally
# permanent. Toggle this parameter "on" to have the mappings
# in the DNS expire when the DHCP lease expires.

#dns_tracks_dhcp_lease

# If a DHCP client needs a bootfile, send the name of that file in the BOOTP
# 'file' field, not as a DHCP option (option 67). BOOTP clients *always*
# receive a bootfile name in the 'file' field, regardless of this option

#bootfile_not_sent_as_option

# Ignore the hardware  type field. For client s which *don't* use DHCP
# client identifiers, this toggle tells the server to use the clients
# hardware address as its identifier, *BUT* to ignore the hadware
# type field. In the JOIN DB the identifier is stored with a type field
# of zero (which is also the type for those clients which are using
# client idetfifiers)

#ignore_hardware_type

# When "on" server ignores the value of the "broadcast bit" and always
# broadcasts reply, even when the client can receive a pseudo unicast
# reply. This was needed by some Cabletron "smart" bridges.

#force_broadcast_reply.
