tinydyndns-data

tinydyndns-data(8)					      System Manager's Manual						tinydyndns-data(8)

NAME

       tinydyndns-data - add or remove TYPE A record to or from data.cdb

SYNOPSIS

       tinydyndns-data add|remove fqdns

DESCRIPTION

       fqdns consists of one or more argument, each specifying a fully qualified domain name (fqdn).

       tinydyndns-data	adds a TYPE A record to or removes it from data.cdb in the current directory.  Other than tinydns-data(8), tinydyndns-data
       does not know about the source file data but changes the binary database data.cdb directly.

       tinydyndns-data reads data.cdb and copies its data to data.tmp.	While reading the records, tinydyndns-data checks for each fqdn  in  fqdns
       if  this  hostname  has a TYPE A record in data.cdb, drops the record when called with the option remove, or refuses to add the record when
       called with the option add.

       When called with the option add, tinydyndns-data then adds all new fqdns to data.tmp.  The data of the newly created records can optionally
       be controlled through the environment, see below.  Finally tinydyndns-data renames data.tmp to data.cdb.

OPTIONS

       add    For each fqdn in fqdns, add a TYPE A record for fqdn to data.cdb with the default IP address (127.14.14.14).

       remove For each fqdn in fqdns, remove all TYPE A records for fqdn from data.cdb.

ENVIRONMENT

       IP     The  environment	variable IP overrides the default IP address (``127.14.14.14'') for newly created records.  $IP must be a valid IP
	      address.

       TTL    time-to-live.  The environment variable TTL overrides the default time-to-live in seconds (0 if TTD is set, otherwise 5).  $TTL must
	      be an integer.

       TTD    time-to-die.  $TTD must be an integer, specifying a number of seconds.  If TTD is set, the timestamp of newly created records is set
	      to the current time plus $TTD seconds, and TTL is set to zero by default, so that tinydns(8) interpretes the timestamp  as  time-to-
	      die.   Note:  you  probably  want  to adjust SOA ttl, or create a wildcard record, to prevent DNS caches from caching nxdomain, when
	      using this feature.

       LOC    location.  $LOC must be two characters long.  If LOC is set, it specifies the client location for newly created records.

EXIT CODES

       tinydyndns-data exits 111 if anything goes wrong and leaves data.cdb unchanged.

       tinydyndns-data exits 0 if all fqdns were processed and the new data.cdb was written.

       For each fqdn in fqdns that tinydyndns-data was not able to remove or add (e.g., not there, or already there), it increases the	exit  code
       by one and exits non-zero (maximum is 100).

FILES

	./data.cdb
	./data.tmp
