Bind 9 Administrator Reference Manual

Chapter 6. BIND 9 Configuration Reference
Note: Not yet implemented in BIND9.
sig-validity-interval
Specifies the number of days into the future when DNSSEC signatures automatically generated as a
result of dynamic updates (Section 4.1) will expire. The default is 30 days. The signature inception
time is unconditionally set to one hour before the current time to allow for a limited amount of
clock skew.
min-refresh-time
max-refresh-time
min-retry-time
max-retry-time
These options control the server’s behavior on refreshing a zone (querying for SOA changes) or
retrying failed transfers. Usually the SOA values for the zone are used, but these values are set by
the master, giving slave server administrators little control over their contents.
These options allow the administrator to set a minimum and maximum refresh and retry time either
per-zone, per-view or globally. These options are valid for slave and stub zones, and clamp the SOA
refresh and retry times to the specified values.
6.2.14.15. The Statistics File
The statistics file generated by BIND 9 is similar, but not identical, to that generated by BIND 8.
The statistics dump begins with the line +++ Statistics Dump +++ (973798949), where the number in
parentheses is a standard Unix-style timestamp, measured as seconds since January 1, 1970. Following
that line are a series of lines containing a counter type, the value of the counter, optionally a zone name,
and optionally a view name. The lines without view and zone listed are global statistics for the entire
server. Lines with a zone and view name for the given view and zone (the view name is omitted for the
default view). The statistics dump ends with the line — Statistics Dump — (973798949), where the
number is identical to the number in the beginning line.
The following statistics counters are maintained:
