Unless otherwise overridden with the \fB\-c\fR flag, the program reads: .IP /etc/key.dns_resolver.conf .P Configuration options are given in \fBkey[=value]\fR form, where \fBvalue\fR 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. .P 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. .P Leading and trailing spaces and spaces around the '=' symbol will be stripped off. .P Available options include: .TP .B default_ttl= 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. .P 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. .SH FILES .ul /etc/key.dns_resolver.conf .ul 0 .SH SEE ALSO \fBkey.dns_resolver\fR(8)
