Hi Charles,

Put the following in your mararc file:

verbose_level = 3

This will log all queries received. You'll have to do some parsing of
the logfile yourself to extract meaningful information, but it should
return lines like:

May 12 02:48:23 sevensisters maradns.etc_maradns_mararc: Query from:
194.30.0.1 Aaurora.webconquest.com.
May 12 02:48:23 sevensisters maradns.etc_maradns_mararc:  Log: Message
received, processing
May 12 02:48:29 sevensisters maradns.etc_maradns_mararc: Query from:
194.30.0.1 Uaurora.webconquest.com.
May 12 02:48:29 sevensisters maradns.etc_maradns_mararc:  Log: Message
received, processing

I hope this helps.

Kind regards,

Remco
