Net::DNS make test fails on recurse

Hi, I'm trying to install Net::DNS while following the qmail rocks installtions. The `make test TEST_VERBOSE=1` fails with the following text. Details about environment as follows: 800mhz Athlon running FreeBSD5.3 uname -a gives: FreeBSD mailserver2.clarke-family.org.uk 5.3-RELEASE FreeBSD 5.3-RELEASE #0: Fri Nov 5 04:19:18 UTC 2004 root@harlow.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386 perl v5.8.5 built for i386-freebsd-64int (rebuilt with ENABLE_SUIDPERL=true) My DNS (192.168.3.1) is an ipcop box.

ok 8 - anwer section had RRs Server [192.168.3.1] did not give answers at /downloads/qmailrocks/perlmods/source/Net-DNS- 0.48_01/blib/lib/Net/DNS/Resolver/Recurse.pm line 73. Server [192.168.3.1] did not give answers at /downloads/qmailrocks/perlmods/source/Net-DNS- 0.48_01/blib/lib/Net/DNS/Resolver/Recurse.pm line 73. not ok 9 192.168.3.1 is RFC1918 space. That indicates to me that that server is not on the public internet and may not be able to recurse. if you do a 'dig @192.168.3.1 net-dns.org SOA' do you get an answer? --Olaf

You are correct in that 192.168.3.1 is my firewall, which also serves as my local DNS server.

I think that your firewall is not transparent to DNS queries. The test fails on queries directly to authoritative servers. So the question I should have asked was: Does dig @193.0.4.49 net-dns.org SOA give you an answer... and that is probably no. --Olaf

Well, it looks like I get something, see below.

Looks like an answer to me :-) Hmmm... in t/10-recurse.t can you change the following: # test the callback { my $res = Net::DNS::Resolver::Recurse->new ; my $count; into # test the callback { my $res = Net::DNS::Resolver::Recurse->new (debug=>1) ; my $count; do perl -Iblib/lib t/10-recurse.t and show the output? --Olaf

The "REFUSED" part is confusing. Your nameserver (192.168.3.1) did answer once, and REFUSED a second time, it seems. So I think this problem is really related to your setup. On the other hand I think that the test itself could be made somewhat more resilient for these situation. I will also review the do_recurse function. May take a while. --Olaf
