check_ircd: IPv6 support (#1995)
The prior bindRemote function was restricted to IPv4 by explicitly using address family specific functions as pack_sockaddr_in or unparametrized gethostbyname. Since Perl 5.14, released in early 2013, there is IO::Socket::IP, which supports lookups and connects for a dual stacked network. By switching the connection establishment code, the plugin is now able to establish connections to IPv6-only hosts. Furthermore, additional -4 and -6 flags were introduced to enforce a specific address family. > $ netstat -p tcp -ln | grep 6667 > tcp6 0 0 *.6667 *.* LISTEN > $ ./plugins-scripts/check_ircd -H localhost > IRCD ok - Current Local Users: 4 > $ ./plugins-scripts/check_ircd -H localhost -4 > IRCD UNKNOWN: Could not start socket (Connection refused) > $ ./plugins-scripts/check_ircd -H localhost -6 > IRCD ok - Current Local Users: 4
