Hi. I'm a newbie in NSD. I want using NSD instead of bind for my DNS Autho Slave. (We're using Bind 9.11 for Master and Slave DNS). In my system, we log all query from client to my dns server by query-log (category queries)... So, my asks: How to config log query in NSD without using TAP. And, why have many dns soft, dns system don't support log query. Is monitoring log query on DNS Authoritive server really necessary? How to monitor abnormal, and tracing in DNS without monitoring query logs. -- _____________________________________ Mr Nguyen Huy Bac DNS Administrator Tel: +084.2435564944 Email: huybac.nguyen at gmail.com Skype: huybac.nguyen at hotmail.com -------------- next part -------------- An HTML attachment was scrubbed...

You can log queries by running tcpdump on the server, with an appropriate filter rule to capture UDP and TCP packets to port 53. Regards, Anand
