# options for the nsd server
server:
# Number of NSD servers to fork. Put the number of CPUs to use here.
# server-count: 1
# uncomment to specify specific interfaces to bind (default are the
# wildcard interfaces 0.0.0.0 and ::0).
# For servers with multiple IP addresses, list them one by one,
# or the source address of replies could be wrong.
# Use ip-transparent to be able to list addresses that turn on later.
# ip-address: 1.2.3.4
# ip-address: 1.2.3.4@5678
# ip-address: 12fe::8ef0
# Allow binding to non local addresses. Default no.
# ip-transparent: no
# use the reuseport socket option for performance. Default no.
# reuseport: no
# enable debug mode, does not fork daemon process into the background.
# debug-mode: no
# listen on IPv4 connections
# do-ip4: yes
# listen on IPv6 connections
# do-ip6: yes
# port to answer queries on. default is 53.
# port: 53
# Verbosity level.
# verbosity: 0
# After binding socket, drop user privileges.
# can be a username, id or id.gid.
# username: @user@
# Run NSD in a chroot-jail.
# make sure to have pidfile and database reachable from there.
# by default, no chroot-jail is used.
# chroot: "@configdir@"
# The directory for zonefile: files. The daemon chdirs here.
# zonesdir: "@zonesdir@"
# the list of dynamically added zones.
# zonelistfile: "@zonelistfile@"
# the database to use
# if set to "" then no disk-database is used, less memory usage.
# database: "@dbfile@"
# log messages to file. Default to stderr and syslog (with
# facility LOG_DAEMON). stderr disappears when daemon goes to bg.
# logfile: "@logfile@"
# File to store pid for nsd in.
# pidfile: "@pidfile@"
# The file where secondary zone refresh and expire timeouts are kept.
# If you delete this file, all secondary zones are forced to be
# 'refreshing' (as if nsd got a notify). Set to "" to disable.
# xfrdfile: "@xfrdfile@"
# The directory where zone transfers are stored, in a subdir of it.
# xfrdir: "@xfrdir@"
# don't answer VERSION.BIND and VERSION.SERVER CHAOS class queries
# hide-version: no
# version string the server responds with for chaos queries.
# default is 'NSD x.y.z' with the server's version number.
# version: "NSD"
# identify the server (CH TXT ID.SERVER entry).
# identity: "unidentified server"
# NSID identity (hex string, or "ascii_somestring"). default disabled.
# nsid: "aabbccdd"
# Maximum number of concurrent TCP connections per server.
# tcp-count: 100
# Maximum number of queries served on a single TCP connection.
# By default 0, which means no maximum.
# tcp-query-count: 0
# Override the default (120 seconds) TCP timeout.
# tcp-timeout: 120
# Preferred EDNS buffer size for IPv4.
# ipv4-edns-size: 4096
# Preferred EDNS buffer size for IPv6.
# ipv6-edns-size: 4096
# statistics are produced every number of seconds. Prints to log.
# Default is 0, meaning no statistics are produced.
# statistics: 3600
# Number of seconds between reloads triggered by xfrd.
# xfrd-reload-timeout: 1
# log timestamp in ascii (y-m-d h:m:s.msec), yes is default.
# log-time-ascii: yes
# round robin rotation of records in the answer.
# round-robin: no
# check mtime of all zone files on start and sighup
# zonefiles-check: yes
# write changed zonefiles to disk, every N seconds.
# default is 0(disabled) or 3600(if database is "").
# zonefiles-write: 3600
# RRLconfig
# Response Rate Limiting, size of the hashtable. Default 1000000.
# rrl-size: 1000000
# Response Rate Limiting, maximum QPS allowed (from one query source).
# If set to 0, ratelimiting is disabled. Also set
# rrl-whitelist-ratelimit to 0 to disable ratelimit processing.
# Default is @ratelimit_default@.
# rrl-ratelimit: 200
# Response Rate Limiting, number of packets to discard before
# sending a SLIP response (a truncated one, allowing an honest
# resolver to retry with TCP). Default is 2 (one half of the
# queries will receive a SLIP response, 0 disables SLIP (all
# packets are discarded), 1 means every request will get a
# SLIP response. When the ratelimit is hit the traffic is
# divided by the rrl-slip value.
# rrl-slip: 2
# Response Rate Limiting, IPv4 prefix length. Addresses are
# grouped by netblock.
# rrl-ipv4-prefix-length: 24
# Response Rate Limiting, IPv6 prefix length. Addresses are
# grouped by netblock.
# rrl-ipv6-prefix-length: 64
# Response Rate Limiting, maximum QPS allowed (from one query source)
# for whitelisted types. Default is @ratelimit_default@.
# rrl-whitelist-ratelimit: 2000
