validating DNS resolver
unwind is a validating DNS resolver. It is
intended to run on client machines like workstations or laptops and only
listens on localhost.
unwind sends DNS queries to
nameservers to answer queries and switches to resolvers learned from
dhclient(8) if it detects that DNS
queries are blocked by the local network. It periodically probes if DNS is
no longer blocked and switches back to querying nameservers itself.
unwind is usually started at boot time,
and can be enabled by setting the following in
prepend domain-name-servers 127.0.0.1;
unwind can be controlled with
the unwindctl(8) utility.
The options are as follows:
unwindwill run in the foreground and log to stderr.
-voptions increase the verbosity.
