Create a basic configuration of /etc/pdnsd/pdnsd.conf, you can use -# /etc/pdnsd/pdnsd.conf.example to start. -# -# Additional configuration will be created automatically be resolvconf. -# The generated server sections has labels starting with "resolvconf", so -# -# DO NOT USE "resolvconf" IN YOUR LABELS! -# -# Check if the status_ctl is set to "on", otherwise the configuration -# will not be automatically reloaded - see sample config file. -# -# You are free to edit automatically created server sections, but always -# write one option per line. There are few options that are always recreated -# and your changes in them will be lost. Here is the list (with example -# values): -# -# preset=on; -# ip="192.168.0.1","192.168.0.2"; -# include=".net",".com";' -# -# The exclude directive in "resolvconf" server section is partly recreated. -# Known (configured) domains in the form "." or ".." are -# added and removed automatically, unknown domains (also those not in -# the format above) found in this directive are kept. -# -# The sample configuration file /etc/pdnsd/pdnsd.conf prepared to work -# with resolvconf would look like this: -# -#global { -# perm_cache=2048; -# run_as="pdnsd"; -# status_ctl = on; # Important to enable status control -# run_ipv4=on; -# par_queries=2; # How many servers are probed in parallel -# interface = "lo"; # Interface on which the pdnsd listens -#} -# -# 2. The last step is to configure dns configuration for /etc/resolv.conf -# for the lo interface.
