DNSPROXY(1) General Commands Manual DNSPROXY(1) NAME dnsproxy -- DNS proxy SYNOPSIS dnsproxy [-dhV] [-c file] DESCRIPTION The dnsproxy daemon waits for nameserver queries on a user specified ad- dress, dispatches these queries to authoritative and recursive nameservers and forwards the received answers back to the original client. The options are as follows: -c file Read configuration from file. -d Detach from current terminal and run as background process. -h Show usage. -V Show version. If a client from an internal IP address does a recursive lookup the query is forwarded to a recursive DNS server. Authoritative queries and queries coming from clients in foreign networks are forwarded to an authoritative DNS server. CONFIGURATION FILE At startup dnsproxy reads a configuration file specified via the -c option or at the default location of /etc/dnsproxy.conf. The following keywords are recognized: authoritative IP Address of the authoritative nameserver [required]. recursive IP Address of the recursive nameserver [required]. listen IP Local address (defaults to 0.0.0.0). port number Local port number (defaults to 53). chroot path A path to chroot to before starting to answer queries. user name A user to change to before starting to answer queries. authoritative-timeout seconds Time in seconds when authoritative queries time out (defaults to 10). recursive-timeout seconds Time in seconds when recursive queries time out (defaults to 90). authoritative-port number Port number on authoritative nameserver (defaults to 53). recursive-port number Port number on recursive nameserver (defaults to 53). statistics seconds Period between output of statistics (defaults to 3600). Use 0 to disable output of statistics completely. internal network Declare networks recognized as internal and thus eligible to do recursive queries. One network in CIDR notation per keyword. EXAMPLE authoritative 10.1.1.1 recursive 127.0.0.1 recursive-port 10053 listen 192.168.1.1 port 53 chroot /var/empty user nobody internal 192.168.1.0/24 internal 127.0.0.1 STATISTICS Every hour (by default) dnsproxy logs the collected statistics about its usage to standard error (or syslog when running detached). Statistics look like ActiveQr AuthorQr RecursQr AllQuery Answered 0 0 0 0 0 TimeoutQ DroppedQ DroppedA LateAnsw HashColl 0 0 0 0 0 and have the following meaning: ActiveQr Number of currently active queries proxied to the servers. AuthorQr Accumulated number of authoritative queries. RecursQr Accumulated number of recursive queries. AllQuery Accumulated number of all queries ever received. Answered Accumulated number of answered queries. TimeoutQ Accumulated number of queries that did not receive an answer in time. DroppedQ Accumulated number of dropped queries (e.g. transmission errors). DroppedA Accumulated number of dropped answers. LateAnsw Accumulated number of answers received after the timeout period. HashColl Accumulated number of hash collisions in the query list. SEE ALSO named(1) VERSION This manual page describes dnsproxy version 1.17.
