This is not really CentOS-specific - sorry. On a name server, I would like to log ns queries (specifically, queries which result with no answer) regarding one domain (for which my ns is authoritative). Is this possible? I know you can turn on logging "globally" using the logging section of named.conf. - Jussi -- Jussi Hirvi * Green Spot Suvilahdenkatu 1 B 78 * 00500 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358 40 771 2098 (only sms) jussi.hirvi at greenspot.fi * http://www.greenspot.fi
