# Do IPv6 ping tests as "conn6".
# This server script is based on a shell script from Debian hobbit-plugins
# 20101207 package, but rewritten in Perl.
#
# Just add conn6 to the services of a host and this script will ping6 the
# AAAA record of the given host.
# Alternatively you can add a comma separated list of IPv6 addresses or
# hostnames that resolve to IPv6 addresses as a parameter to conn6, to ping6
# all these addresses.
# Examples:
# 10.1.2.3 foo # ftp conn6:2001:db8:1::42
# 10.1.2.4 bar # smtp conn6
# 10.1.2.5 baz # conn6:baz.example.com dialup
# 10.1.2.6 router # conn6:2001:db8:1::1,2001:db8:2::1
