Thanks for the clear report. The bug seemed to be caused because in earlier versions of perl AF_INET6 was not defined in Socket.pm. use strict subs; will then stumble. It turns out that the developers of MRTG were aslo bitten by this (see thread starting at: http://lists.ee.ethz.ch/mrtg-developers/msg00198.html ) Using AF_INET6() instead of AF_INET6 solved their problem (Lorenzo, who was involved in that mrtg fix is sharing an office with me and just confirmed this). I have patched this and released 0.51_01 which should be available on CPAN shortly. Alternatively you can pull it from http://www.net-dns.org/download/Net-DNS-0.51_01.tar.gz --Olaf

In Cygwin using NET::DNS 0.51_01 I get Your vendor has not defined Socket macro AF_INET6, used at /usr/lib/perl5/site_perl/5.8/cygwin/Net/DNS/Resolver/Base.pm line 874 It seems pretty clear, but in case you need my test case that results in that please let me know.

This is a but generated by IO::Socket::INET6, did you get that installed without problems? Installation of IO::Socket::INET6 fails on my system, exactly with the same bug. (The test for the support of INET6 is based on assumption that the existence of IO::Socket::INET6 and Socket6 modules indicates system support for INET6, I can add an additional test but wonder if you did not encounter problems during the "make test" for cygwin. puzzled --Olaf

Oh eh yeah the test case would be appreciated if you _do_not_ have IO::Socket:;INET6 installed and you hit this message. --Olaf

The test case won't do much good because what happened was a problem in my DNS configuration that resulted in an error message in Base.pm and that error message refers to AF_INET6. But it is easy to see at line 874 where the error message does not test $has_test6 unless (defined ($sock[ $nssockfamily ])){ $self->errorstring("Send error: cannot reach $nsname (" . ( ($nssockfamily == AF_INET6()) ? "IPv6" : "" ). ( ($nssockfamily == AF_INET) ? "IPv4" : "" ). ") not available" It might be worth grepping for AF_INET6 in the source to verify that every use of it is inside some conditional (block or statement) that ensures that $has_test6 is true.

Good point, will do... Will also look at your patch for the the persistent sockets, I have some other obligations during this week so it may take a couple of days. --Olaf

In line 759 of lib/Net/DNS/Resolver/Base.pm taken from OLAF/Net-DNS-0.52.tar.gz there's still an occurence of this constant without the parenthesis pair, which triggers the error reported by <iwhite@victoria.tc.ca> here: $sock[AF_INET6] = IO::Socket::INET6->new( Regards, fany

Thanks Fany, Fixed on the subversion repository "trunk" --Olaf
