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)  interprets  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).
