check_ircd: IPv6 support (#1995)

2024-03-18T09:05:04Z

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

use pack_sockaddr_in rather than hand-rolled

2023-10-06T09:15:35Z

On some OS, sockaddr structs include a length field. Perl's pack_sockaddr_in takes this into account; the hand-rolled "pack('S n a4 x8'..." doesn't do so, resulting in connection failures.

Restrict the nickname length of the test user for check_ircd

2021-10-20T09:14:44Z

check_ircd was using the string `ircd` plus the PID as a nickname for connecting to a IRC network by default. This caused errors, when the PID was too high and the network restricted the length of the nickname to 9 characters. This patch "fixes" this by just cutting it of, if it gets too big.

utils.pm locate is already convered by FindBin

Don't rely on FindBin module to locate utils.pm

2014-07-06T17:55:03Z

As the FindBin module doesn't work with ePN, set the path to utils.pm explicitly at build time. Keep using FindBin additionally, so that the plugins can also be executed from the build directory. Closes #1271.

Disable Perl's "taint" checks

2014-02-28T21:05:18Z

Perl's "taint" checks don't like `use lib "$FindBin::Bin"'. Cf. http://www.perlmonks.org/?node_id=585299

Replace "plugins-scripts/subst.in" foo

2014-02-28T12:28:33Z

Remove the buggy and complex awk(1) magic in "plugins-scripts/subst.in" in favor of simple sed(1) substitutions. The plugins in the "plugins-scripts" directory now always use the PATH specified via "./configure --trusted-path", or the default PATH hard-coded in "configure.ac". Fixes #1242.
