ixfrdist.yml - Man Page
The ixfrdist configuration file
Synopsis
ixfrdist.yml
Description
ixfrdist reads its configuration from a YAML file. By default, this file is called ixfrdist.yml and is read from the directory configured as SYSCONFDIR when building the software. This directory is usually one of /etc/pdns, /etc/powerdns. Run ixfrdist --help to see the default.
Example
listen: - 192.0.2.2 - '[2001:DB8:ABCD::2]:5300' - 127.0.0.1 acl: - 127.0.0.1 - '192.0.2.0/24' - '2001:DB8:ABCD:1234::/64' work-dir: /var/lib/ixfrdist uid: ixfrdist gid: ixfrdist domains: - domain: example.com master: 192.0.2.18:5301 max-soa-refresh: 1800 notify: - 192.0.3.1 - 192.0.3.2:5301 - domain: example.net master: 2001:DB8:ABCD::2
Options
- listen
The list of addresses to listen on. ixfrdist listens on both TCP and UDP. When no port is specified, 53 is used. When specifying ports for IPv6, use the "bracket" notation. By default, ixfrdist listens on 127.0.0.1:53 and [::1]:53.
- acl
A list of netmasks that are allowed to query ixfrdist and request AXFRs and IXFRs Entries without a netmask will be interpreted as a single address. By default, the ACL is set is 127.0.0.0/8 and ::1/128.
- axfr-max-records
Maximum number of records allowed in an AXFR transaction requested by ixfrdist. This may prevent untrusted sources from using all the process memory. By default, this setting is 0, which means "unlimited".
- axfr-timeout
Timeout in seconds an AXFR transaction requested by ixfrdist may take. Increase this when the network to the authoritative servers is slow or the domains are very large and you experience timeouts. Defaults to 20.
- failed-soa-retry
Time in seconds between retries of the SOA query for a zone we have never transferred. Defaults to 30.
- compress
Whether record compression should be enabled, leading to smaller answers at the cost of an increased CPU and memory usage. Defaults to false.
- work-dir
The directory where the domain data is stored. When not set, the current working directory is used. This working directory has the following structure: work-dir/ZONE/SERIAL, e.g. work-dir/rpz.example./2018011902. It is highly recommended to set this option, as the current working directory might change between invocations. This directory must be writable for the user or group ixfrdist runs as.
- keep
Amount of older copies/IXFR diffs to keep for every domain. This is set to 20 by default.
- tcp-in-threads
Number of threads to spawn for TCP connections (AXFRs) from downstream hosts. This limits the number of concurrent AXFRs to clients. Set to 10 by default.
- gid
Group name or numeric ID to drop privileges to after binding the listen sockets. By default, ixfrdist runs as the user that started the process.
- uid
User name or numeric ID to drop privileges to after binding the listen sockets. By default, ixfrdist runs as the user that started the process.
- domains
A list of domains to redistribute. This option is mandatory.
- domain
The domain name to transfer from the master. Mandatory.
- master
IP address of the server to transfer this domain from. Mandatory.
- max-soa-refresh
Cap the refresh time to the given maximum (in seconds). Optional.
- notify
The list of destinations to send NOTIFY to. Optional.
- webserver-address
IP address to listen on for the built-in webserver. When not set, no webserver is started.
- webserver-acl
A list of networks that are allowed to access the ixfrdist webserver. Entries without a netmask will be interpreted as a single address. By default, this list is set to 127.0.0.0/8 and ::1/128.
- webserver-loglevel
How much the webserver should log: 'none', 'normal' or 'detailed'. When logging, each log-line contains the UUID of the request, this allows finding errors caused by certain requests. With 'none', nothing is logged except for errors. With 'normal' (the default), one line per request is logged in the style of the common log format:
[NOTICE] [webserver] 46326eef-b3ba-4455-8e76-15ec73879aa3 127.0.0.1:57566 "GET /metrics HTTP/1.1" 200 1846
with 'detailed', the full requests and responses (including headers) are logged along with the regular log-line from 'normal'.
