Subject: [PATCH] Decrease the number of individual sites listed in log.
|
|
|
|
By default 30 first servers are listed individually to system log, and
|
|
then a count of the remaining items. With e.g. a NXDOMAIN based adblock
|
|
service, dnsmasq lists 30 unnecessary ad sites every time when dnsmasq
|
|
evaluates the list. But the actual nameservers in use are evaluated last
|
|
and are not displayed as they get included in the "remaining items" total.
|
|
|
|
Handle the "local addresses only" separately and list only a few of them.
|
|
Remove the "local addresses only" from the general count.
