I would not recommend sucking in your dns log into array, rather, read line by line and iterate over the file, line by line.

True.. reading into an array can get a bit nasty, if your server logs are a few gigabytes in size. Could use C, also... http://pastebin.com/f4c2ff010 Scanning your logs after the fact is definitely not as good as separating DNS servers that are authoritative for zones and picking nameserver software such as TinyDNS or similar options for authoritative DNS usage that won't respond to queries for the root or other zones the DNS server is not directed to be used for, and using acls/firewalls to prevent outside queries against other DNS servers that aren't delegated zones. It's a bit difficult to apply a BIND patch that doesn't exist yet in vendor-supplied implementations of BIND, at least.. -- -J
