NAME

       tinydns - a DNS server.

DESCRIPTION

       tinydns  accepts  iterative  DNS queries from hosts around the Internet, and responds with
       locally configured information.

Configuration

       This is a reference page.  For tutorial information, see the instructions for
       running a DNS server (http://cr.yp.to/djbdns/run-server.html).

       Normally tinydns is set up by the tinydns-conf(8) program.

       tinydns runs chrooted in the directory specified by the $ROOT environment variable,  under
       the uid and gid specified by the $UID and $GID environment variables.

       tinydns  listens for incoming UDP packets addressed to port 53 of $IP.  It does not listen
       for TCP queries.

       tinydns answers queries as specified by  data.cdb,  a  binary  file  created  by  tinydns-
       data(8).

Further details

       tinydns  rejects  zone-transfer  requests,  inverse  queries,  non-Internet-class queries,
       truncated packets, and packets that contain anything other than a single query.

       tinydns, like BIND, includes NS records with answers to most queries.  This increases  DNS
       packet  sizes, but it draws queries away from parent servers, and reduces the frequency of
       long DNS delays.  With the default tinydns-data(8) cache  times,  a  client  that  uses  a
       normal record at least once every day will always have the corresponding NS records cached
       and will never have to talk to parent servers.
