- This is a quick hack I wrote to assist in tracking down broken
- DNS resolvers.
-
- Invoke it as: trnamed < named.run > named.log
-
- The .log file is a reduced form of named.run whose output is useful for
- detecting broken resolver behavior patterns. Two additional output
- files are produced: named.byaddr, a frequency count of requests by
- source IP addresses; named.byname, a frequency count of the name
- being looked up.
