key.dns_resolver.conf - Kernel DNS resolver config

This file is used by the key.dns_resolver(5) program to set parameters. Unless otherwise overridden with the -c flag, the program reads:
/etc/key.dns_resolver.conf

Configuration options are given in key[=value] form, where value is optional. If present, the value may be surrounded by a pair of single ('') or double quotes ("") which will be stripped off. The special characters in the value may be escaped with a backslash to turn them into ordinary characters.

Lines beginning with a '#' are considered comments and ignored. A '#' symbol anywhere after the '=' makes the rest of the line into a comment unless the '#' is inside a quoted section or is escaped.

Leading and trailing spaces and spaces around the '=' symbol will be stripped off.

Available options include:

default_ttl=<number>
The number of seconds to set as the expiration on a cached record. This will be overridden if the program manages to retrieve TTL information along with the addresses (if, for example, it accesses the DNS directly). The default is 5 seconds. The value must be in the range 1 to INT_MAX.

The file can also include comments beginning with a '#' character unless otherwise suppressed by being inside a quoted value or being escaped with a backslash.
