Subject:	t/ping.t fails (with recent Net::Ping versions?)

My smoker machines started to report the following failure in the test suite: ... getaddrinfo(aaa.bbb.ccc,,AF_INET) failed - hostname nor servname provided, or not known at /home/cpansand/.cpan/build/2016102915/Data-Checker-1.06-STvcDE/blib/lib/Data/Checker/Ping.pm line 37. t/ping.t .......... Dubious, test returned 83 (wstat 21248, 0x5300) No subtests run ...

Technical analysis revealed that Net-Ping-External tests do cross-check for foreign hosts to match the result of ping with Net-Ping-External, but not with 127.0.0.1. On many hosts the firewall forbids now icmp to localhost. hence these tests error. Before Net-Ping 2.51 these tests were never executed. The Net-Ping-External tests need to be fixed for firewalled localhost ICMP. 1..6 ok 1 not ok 2 not ok 3 ok 4 not ok 5 not ok 6 Net::Ping::External version: 0.15 2/6 tests passed. Successful tests: use Net::Ping::External qw(ping) ping(host => 'some.non.existent.host.') Failed tests: ping(host => '127.0.0.1') ping(host => '127.0.0.1', timeout => 5) ping(host => '127.0.0.1', count => 10) ping(host => '127.0.0.1', size => 32) -- Reini Urban

I've had several problems making the ping checks always work, so I've disabled them by default. I've released a new version which will not run the tests. I'll work on the tests separately to try to make them more robust.
