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.
