NAME

       tinydns - DNS content server


DESCRIPTION

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


CONFIGURATION

       Normally tinydns is set up by the tinydns-conf 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.


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 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.
