NAME
unbound - Unbound DNS validating resolver 1.4.21.
SYNOPSIS
unbound [-h] [-d] [-v] [-c cfgfile]
DESCRIPTION
Unbound is an implementation of a DNS resolver, that does caching and
DNSSEC validation.
The available options are:
-h Show the version and commandline option help.
-c cfgfile
Set the config file with settings for unbound to read instead of
reading the file at the default location,
/usr/local/etc/unbound/unbound.conf. The syntax is described in
unbound.conf(5).
-d Debug flag, do not fork into the background, but stay attached to
the console. This flag will also delay writing to the logfile
until the thread-spawn time. So that most config and setup errors
appear on stderr.
-v Increase verbosity. If given multiple times, more information is
logged. This is in addition to the verbosity (if any) from the
config file.
SEE ALSO
unbound.conf(5), unbound-checkconf(8).
