pdnsd is a proxy dns server with permanent caching (the cache contents are
|
2001-01-28 07:51:34 +00:00
|
|
|
written to hard disk on exit) that is designed to cope with unreachable or
|
2000-12-14 03:27:37 +00:00
|
|
|
down dns servers (for example in dial-in networking).
|
|
|
|
|
pdnsd can be used with applications that do dns lookups, eg on startup, and
|
2001-01-28 07:51:34 +00:00
|
|
|
can't be configured to change that behavior, to prevent the often minute-long
|
2000-12-14 03:27:37 +00:00
|
|
|
hangs (or even crashes) that result from stalled dns queries. Some Netscape
|
2001-01-28 07:51:34 +00:00
|
|
|
Navigator versions for Unix, for example, expose this behavior.

|
|
pdnsd is configurable via a file and supports run-time configuration using the
|
|
|
|
|
program pdnsd-ctl that comes with pdnsd. This allows you to set the status
|
|
|
|
|
flags of servers that pdnsd knows (to influence which servers pdnsd will
|
|
|
|
|
query), and the addition, deletion and invalidation of DNS records in pdnsd's
|
|
|
|
|
cache.
|
|
|
|
|
Parallel name server queries are supported. This is a technique that allows
|
|
|
|
|
querying several servers at the same time so that very slow or unavailable
|
|
|
|
|
servers will not block the answer for one timeout interval.
|
|
|
|
|
Since version 1.0.0, pdnsd has full IPv6 support.
