## NAME
       key.dns_resolver - upcall for request-key to handle dns_resolver keys

## SYNOPSIS
       **/sbin/key.dns_resolver **<key>
       **/sbin/key.dns_resolver **--dump-config [-c <configfile>]
       **/sbin/key.dns_resolver **-D [-v] [-v] [-c <configfile>] <desc>
       <calloutinfo>

## DESCRIPTION
       This  program is invoked by request-key on behalf of the kernel when kernel services (such as
       NFS, CIFS and AFS) want to perform a hostname lookup and the kernel does  not  have  the  key
       cached.  It is not ordinarily intended to be called directly.

       There  program  has  internal  parameters  that can be changed with a configuration file (see
       [key.dns_resolver.conf(5)](https://www.chedong.com/phpMan.php/man/key.dnsresolver.conf/5/markdown) for more information).  The default configuration file is  in  /etc,
       but this can be overridden with the **-c **flag.

       The  program  can  be  called  in debugging mode to test its functionality by passing a **-D **or
       **--debug **flag on the command line.  For this to work, the key description and the callout  in‐
       formation must be supplied.  Verbosity can be increased by supplying one or more **-v **flags.

       The  program may also be called with **--dump-config **to show the values that configurable para‐
       meters will have after parsing the config file.

## ERRORS
       All errors will be logged to the syslog.
