mydns.conf(5)
NAME
mydns.conf - mydns(8) configuration file.
DESCRIPTION
- mydns.conf is read by mydns(8) on startup. The default
- location of this file is /etc/mydns.conf.
- A mydns.conf might look something like this:
# /etc/mydns.conf
# Configuration file for the MyDNS name daemon
db-host = dbserver.example.com
db-user = mydnsuser
db-password = Gr8DNS!- Each line in the file may contain only one configuration
- variable. All allowable configuration variables are described in
- this man page. The syntax for a configuration line is `option [=
- value]'. All configuration variables have default values, which
- are used if the variable is omitted from the mydns.conf. These
- defaults are listed in parentheses after the variable syntax.
- All text following a hash mark (`#') and empty lines are
- ignored. If you need to specify an actual hash mark in a option
- value, escape it by prefixing it with a backslash (´) character.
- The mydns(8) program has a convenient command-line option
- that will output all current configuration variables in
- mydns.conf format. If you are creating a mydns.conf file for the
- first time, this is a great way to create a template that you can
- customize. See mydns(8) for details.
DATABASE INFORMATION
- The following configuration variables tell MyDNS about
- your database server.
- db-host = hostname (`localhost')
- Connect to the database server located at hostname.
- db-user = username
- Use username when authenticating with the database
- server.
- db-password = password
- Use password when authenticating with the database
- server.
- database = name (`mydns')
- Read resource record information from the database
- called name. The specified dbuser must have SELECT privileges on
- the specified database.
GENERAL OPTIONS
- The following configuration variables control the general
- behavior of the name daemon.
- user = username (`nobody')
- Run the name daemon with the permissions of user
- username.
- group = groupname (`nogroup')
- Run the name daemon with the permissions of group
- groupname.
- listen = address (`*')
- The name daemon should listen on address. If
- address is *, listen on all addresses. This must be an IP ad
- dress in numbers-and-dots format, or *. Multiple addresses may
- be specified, either separated by commas, or listed on separate
- listen lines, or both. If a port number other than port 53 is
- desired, append `:port' to the address.
- no-listen = address (`*')
- The name daemon should NOT listen on address, even
- if it was specified by listen. This must be an IP address in
- numbers-and-dots format, or *. Multiple addresses may be speci
- fied, either separated by commas, or listed on separate listen
- lines, or both. If a port number other than port 53 is desired,
- append `:port' to the address.
CACHE OPTIONS
- The following configuration variables affect the cache
- used internally by the name daemon.
- zone-cache-size = number (`4096')
- The zone data cache will not contain more than
- number entries. The average entry in the cache is about 128
- bytes. If number is 0, the zone data cache will not be used.
- zone-cache-expire = seconds (`60')
- Entries expire from the zone data cache once they
- are seconds old. If seconds is 0, the zone data cache will not
- be used. If the TTL for any RR in the zone is less than the
- cache expire time, the TTL will be honored.
- reply-cache-size = number (`1024')
- The reply cache will not contain more than number
- entries. The average entry in the cache is about 128 bytes. If
- number is 0, the reply cache will not be used.
- reply-cache-expire = seconds (`30')
- Entries expire from the reply cache once they are
- seconds old. If seconds is 0, the reply cache will not be used.
ESOTERICA
- The following configuration variables affect the name dae
- mon also, but most users will not need to use them.
- log = facility (`LOG_DAEMON')
- The name daemon should log via syslog facility
- facility. facility may be LOG_DAEMON or LOG_LOCAL0 through
LOG_LOCAL7
- stderr only.
pidfile = filename (`/var/run/named.pid') - Create a PID file for the name daemon called
- filename.
- timeout = seconds (`120')
- Incoming queries time out if a reply could not be
- sent after seconds have elapsed.
- multicpu = cpucount (`1')
- Run with multiple processes to support cpucount
- number of processors.
- allow-axfr = bool (`no')
- Should DNS-based zone transfers be allowed?
- allow-tcp = bool (`no')
- Should TCP requests be allowed? (not recommended)
- allow-update = bool (`no')
- Should DNS-based zone updates (RFC 2136) be al
- lowed?
- ignore-minimum = bool (`no')
- Should MyDNS ignore the minimum TTL for zones?
- soa-table = name (`soa')
- The name of the table containing SOA records.
- rr-table = name (`rr')
- The name of the table containing resource record
- data.
- soa-where = string
- An extra WHERE clause to append to queries select
- ing records from the `soa' table.
- rr-where = string
- An extra WHERE clause to append to queries select
- ing records from the `rr' table.
- recursive = address
- If this option is specified, address is the address
- of a DNS server that accepts recursive queries. If MyDNS re
- ceives a query where recursion is desired, and the zone is not
- local, MyDNS will forward the query to the server at address and
- return the result to the client.
SECURITY
- The mydns.conf file should be readable only by the root
- user (uid=0) since it typically contains a username and password
- allowing access to your database.
FILES
- /etc/mydns.conf
- The default location of the configuration file.
