?where can I get more info on configuration
did it recurses over the next server when name is not found?
If DNSd is enabled, on any hostname query that comes in, TPS will first look in config.ini, and if not found will hand over the query to the system (which will then use whatever dns server has been set).
That can be handy to write a batch that will not depend on hardcoded IP's but rather on a hostname which I can always reuse whatever my network config is (that scenario would work only in plain dhcp mode, not in proxydhcp mode).
Example, "repository.local" hostname dns query comes in, TPS will look for the below in config.ini and will resolve to 192.168.1.100.
Note that this would work also for hostnames such as www.facebook.com, etc and would be seen as DNS hijacking.
