Package: libnet-dns-perl
Version: 0.78-1
Severity: normal
Affects: lintian
I was using lintian to check some packages and noticed that it is now slow as hell. A quick check showed that some perl stuff is sending bogus DNS requests over my lo device. This seems to be this perl script in _select_dns_method.
I am using network-manager in an IPv6 network and my /etc/resolv.conf contains entries like:
search real.example.org
nameserver 192.168.1.1
nameserver fe80::211:22ff:fe33:4455%wlan0
nameserver 2a01:1234:4568:abcd:ef01:2345:6781:abcd
And now I see a DNS query for fe80::::211:22ff:fe33:4455%wlan0 through my lo device when I am trying to start lintian on a package. This is a bogus query for a valid IPv6 link-lokal address nameserver entry and takes ages before it stops the query attempt and actually starts the rest of the lintian tests
