It's important to remember these tools are written by humans that also have busy mornings where they don't get to drink enough coffee... :-) Awhile back we updated an internal tool that generates DNS records as part of a hosted email solution and one of these tools started baulking. Everything we were doing was RFC compliant, but the tool turned red. This spawned a lot of calls to support from customers who took the tool as an omniscient being, support escalated to management because the customer is always right (and were threatening to go elsewhere even after being pointed to relevant RFCs and walking through dig showing everything worked just fine in practice). After triple-checking the RFCs and contacting the maintainer with our justification, the tool started doing the right thing a few weeks later. So now we need tools that check the tools, and they need to be written by omniscient beings... Failing that, the big thing I hope folks learn from this is that automated tools written by third parties are helpful at times, but no substitute for familiarity with standards and generally understanding how things work. _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
