tinydns-edit(8) System Manager's Manual tinydns-edit(8)
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 com‐
piled 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 deter‐
mined 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 automat‐
ically 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 automat‐
ically 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 .

This manual page was created by Jonathan de Boyne Pollard on 2001-04-06.
2001-04-26: A new AUTHOR AND MODIFICATIONS section was added. axfrdns(8) is now men‐
tioned. The description of how server names were auto-generated was clarified. A cut-
and-paste error in the description of the "mx" type was corrected.
