...Plugin 10539 reported a DNS server as allowing recursive queries. I tried to verify this with:

It looks like nessus is relying on the 'ra' bit to determine if recursion is available...correct?
Yes.
If this is the case, why does it report this since the response (from below) is 0x8082?
Also, when the script builds the query, it apparently sets the DNS flags to "dns["flags"] = 0x0100;", but from the packet capture you see that the query is actually 0x0000. Is this correct?
No, it's a bug. Thanks for pointing it out. I've just fixed it.
