Yeah, its 5am – got clients that rely on me to get things done…
DNS: Best free tool to use: http://www.dns.lu/en/EN-LUTestNoms.php
If seeing “not advertising as nameserver”, that means in the zone file that server is not listed:
mochabomb.com. IN NS ns1.mochabomb.com. mochabomb.com. IN NS ns2.mochabomb.com. mochabomb.com. IN NS ns4.mochabomb.com.
.. for the server it resides on – and that record can be a slave record, just need to add all slaves in the master DNS server so that the slave server advertizes itself as an authority….
In /etc/named.conf is where a zone is set as master or slave. A slave can be authoritative if its name is listed/resolved by the master record.
