Sorry I didn't clarify the research I had already done:

- The non-support of IPv6 in the NRPE plugin is indeed a flaw
  in the Nagios source. It's not just a question of rebuilding
  with --with-ipv6 or something like that.

- There seem to have been several efforts to fix that.

- There's a patch floating around in the Debian universe which
  is said to add the missing IPv6 support to the Nagios NRPE
  plugin, but also reported to have some flaws. See
  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=484575

- There's an effort titled NRPE "3.0" which looks promising
  but hasn't shown any activity for two years, so it's unclear
  to me whether it's fit for production use. See
  https://github.com/KristianLyng/nrpe

- Icinga also has a NRPE plugin which is reported to
  (a) support IPv6 and (b) work with Nagios as well.

The aim of my question was to hear how others are dealing with
that situation. Is there someone who has successfully applied the
Debian patch, deployed Kritian Lyng's 3.0 version of NRPE, or
used Icinga's check_nrpe with Nagios on CentOS? Are there other
approaches? Which one appears the most sensible? Or is there just
nobody using Nagios on CentOS in an IPv6 enabled network?
