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) 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 information 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 parameters will have after parsing the config file.

ERRORS

All errors will be logged to the syslog.
