NAME
tinydns-edit - edit the (source form of the) database served by
tinydns/axfrdns
SYNOPSIS
tinydns-edit data data.tmp add type name address
DESCRIPTION
tinydns-edit edits the data file, which is the source form of the
database that is compiled by tinydns-data(8) and that is served by
tinydns(8) and axfrdns(8). The update to data is performed atomically,
by first writing the updated database content to the file data.tmp and
then renaming data.tmp to data . The two files must, of course, reside
on the same volume in order that this can be achieved.
On success, tinydns-edit returns zero. If, for any reason, an error
occurs it will exit with a non-zero code and data will not be changed.
With the "add" verb, tinydns-edit appends to the database a record
whose type is determined by type , with the fully-qualified name name
and the IP address address . type can be one of:
ns A ’.’ record is created. This record specifies that the domain
name is published by a DNS content server that is listening on
the IP address address .
The name of the DNS content server is not directly specifiable.
Names are automatically assigned by tinydns-edit itself,
following the pattern [a-z].ns.name . tinydns-edit will assign
the first letter of the alphabet that is not already used in
another ’.’ or ’&’ record as the name of a DNS content server.
If no letters of the alphabet remain unused, tinydns-edit will
fail.
If a ’.’ or ’&’ record for the domain already exists, proxy DNS
servers are allowed to cache the new record for the same length
of time as they are allowed to cache the existing records.
Otherwise, proxy DNS servers are allowed to cache the record for
up to 3 days.
childns
A ’&’ record is created. This record specifies that queries for
names in the domain name should be referred to a ("child") DNS
content server that is listening on the IP address address .
The name of the DNS content server is not directly specifiable.
Names are automatically assigned by tinydns-edit itself,
following the pattern [a-z].ns.name . tinydns-edit will assign
the first letter of the alphabet that is not already used in
another ’.’ or ’&’ record as the name of a DNS content server.
If no letters of the alphabet remain unused, tinydns-edit will
fail.
If a ’.’ or ’&’ record for the domain already exists, proxy DNS
servers are allowed to cache the new record for the same length
of time as they are allowed to cache the existing records.
Otherwise, proxy DNS servers are allowed to cache the record for
up to 3 days.
mx A ’@’ record is created. This record specifies that mail to
names in the domain name should be sent to an SMTP server that
is listening on the IP address address .
The name of the SMTP server is not directly specifiable. Names
are automatically assigned by tinydns-edit itself, following the
pattern [a-z].mx.name . tinydns-edit will assign the first
letter of the alphabet that is not already used in another ’@’
record as the name of an SMTP server. If no letters of the
alphabet remain unused, tinydns-edit will fail.
It is not possible to specify the distance value for the SMTP
server. tinydns-edit will leave that field blank, meaning that
tinydns-data (8) will use whatever the default value is.
If a ’@’ record for the domain already exists, proxy DNS servers
are allowed to cache the new record for the same length of time
as they are allowed to cache the existing records. Otherwise,
proxy DNS servers are allowed to cache the record for up to 1
day.
host A ’=’ record is created, that proxy DNS servers are allowed to
cache for up to 1 day. This record specifies that the name name
maps to the IP address address and vice versa.
tinydns-edit will fail if a ’=’ record already exists that uses
either name or address .
alias A ’+’ record is created, that proxy DNS servers are allowed to
cache for up to 1 day. This record specifies that the name name
maps to the IP address address but that there is no reverse
mapping.
Because this is an alias record, tinydns-edit will not fail if
there happen to already be existing records that use address .
