       pdnsd-ctl - controls pdnsd


       pdnsd-ctl [-c cachedir] [-q] command [arguments]


       pdnsd-ctl controls pdnsd, a proxy dns server with permanent caching.  Note that the status
       control socket must be enabled (by specifying an option on the pdnsd command  line  or  in
       the configuration file) before you can use pdnsd-ctl.

       -c cachedir
              Set  the  cache  directory  to  cachedir  (must match pdnsd setting).  This is only
              necessary if the directory differs from the default specified at compile time.

       -q     Be quiet unless output is specified by the command or something goes wrong.


       help   [no arguments]

              Print a command summary.

       version [no arguments]

              Print version and license info.

       status [no arguments]

              Print a description of pdnsd's cache status, thread status and configuration.  Also
              shows which remote name servers are assumed to be available.

       server (index|label) (up|down|retest) [dns1[,dns2[,...]]]

              Set the status of the servers with the given index or label to up or down, or force
              a retest. The index is assigned in the order of definition in  pdnsd.conf  starting
              with  0. Use the status command to view the indexes. You can specify all instead of
              an index to perform the action for all servers registered with pdnsd.

              An optional third argument can be given  consisting  of  a  list  of  IP  addresses
              separated by commas or white-space characters. This list will replace the addresses
              of name servers used by pdnsd for the given server section. This feature is  useful
              for  run-time configuration of pdnsd with dynamic DNS data in scripts called by ppp
              or DHCP clients. The last argument may  also  be  an  empty  string,  which  causes
              existing  IP addresses to be removed and the corresponding server section to become

       record name (delete|invalidate)

              Delete or invalidate the records of the given domain name if it is  in  the  cache.
              Invalidation  means  that the records are marked as timed out, and will be reloaded
              if possible. For local records (i.e., records that were given in  the  config  file
              using  a  rr  section, records read from a hosts-style file and records added using
              pdnsd-ctl), invalidation has no effect. Deletion will work, though.

       source fn owner [ttl] [(on|off)] [noauth]

              Load a hosts-style file. Works like using the pdnsd source  configuration  section.
              Owner  and ttl are used as in the source section. ttl has a default of 900 (it does
              not  need  to  be  specified).  The  next  to  last  argument  corresponds  to  the
              serve_aliases  option,  and  is off by default.  noauth is used to make the domains
              non-authoritative (this is similar to  setting  authrec=off  in  the  config  file,
              please  consult the pdnsd.conf(5) man page for what that means).  fn is the name of
              the file, which must be readable by pdnsd.

       add    a addr name [ttl] [noauth]

       add    aaaa addr name [ttl] [noauth]

       add    ptr host name [ttl] [noauth]

       add    cname host name [ttl] [noauth]

       add    mx host name pref [ttl] [noauth]

              Add a record of the given type to the pdnsd cache, replacing existing  records  for
              the  same name and type. The 2nd argument corresponds to the value of the option in
              the rr section that is named like the first argument. The addr argument  may  be  a
              list of IP addresses, separated by commas or white space.  The ttl is optional, the
              default is 900 seconds.  noauth is used to make the domains non-authoritative (this
              is  similar  to  setting  authrec=off  in  the  config  file,  please  consult  the
              pdnsd.conf(5) man page for what that means).  If you want no other record than  the
              newly added in the cache, do pdnsd-ctl record name delete before adding records.

       neg    name [type] [ttl]

              Add a negatively cached record to pdnsd's cache, replacing existing records for the
              same name and type. If no type is given, the whole domain is cached negatively. For
              negatively  cached  records,  errors  are  immediately returned on a query, without
              querying other servers first.  The ttl is optional, the default is 900 seconds.

       config filename

              Reload pdnsd's configuration file.
              The config file must be owned by the uid that pdnsd had when it was started, and be
              readable by pdnsd's run_as uid.  If no file name is specified, the config file used
              at start-up is reloaded.  Note that some configuration changes, like the port or IP
              address  pdnsd  listens  on,  cannot be made this way and you will receive an error
              message.  In these cases, you will have to restart pdnsd instead.

       include filename

              Parse an include file.
              The include file may contain the same type of sections as a config file, expect for
              global  and server sections, which are not allowed. This command can be used to add
              data to the cache without reconfiguring pdnsd.

       eval   string

              Parse a string as if part of an include file.
              The string should hold one or more complete configuration sections, but  no  global
              and  server  sections,  which are not allowed.  If multiple strings are given, they
              will be joined using newline chars and parsed together.

       empty-cache [[+|-]name ...]

              Delete all entries in the cache matching include/exclude rules.
              If no arguments are provided, the cache is completely emptied, freeing all existing
              entries.  Note that this also removes local records, as defined by the config file.
              To restore local records, run "pdnsd-ctl config" immediately afterwards.
              If one or more arguments are provided, these  are  interpreted  as  include/exclude
              names.  If an argument starts with a '+' the name is to be included. If an argument
              starts with a '-' it is to be excluded.  If an argument does not begin with '+'  or
              '-',  a  '+'  is  assumed.   If the domain name of a cache entry ends in one of the
              names in the list, the first match will determine what  happens.  If  the  matching
              name is to be included, the cache entry is deleted, otherwise it remains.  If there
              are no matches, the default action is not to delete.

       dump   [name]

              Print information stored in the cache about name.  If name begins with a dot and is
              not  the  root  domain,  information  about  the  names in the cache ending in name
              (including name without  the  leading  dot)  will  be  printed.   If  name  is  not
              specified, information about all the names in the cache will be printed.

       list-rrtypes [no arguments]

              List  available rr types for the neg command. Note that those are only used for the
              neg command, not for add!


       If you pipe the output of dump command through an application that reads only part of  the
       output  and then blocks (such as more or less), pdnsd threads trying to add new entries to
       the cache will be suspended until the pipe is closed.  It is  preferable  to  capture  the
       output in a file in such a case.
       Report any remaining bugs to the authors.
