NRPE 2.15 was released earlier today. The primary update in this version of NRPE is full support for IPv6.
The NRPE daemon now has the ability to listen on IPv4 and/or IPv6 addresses. In addition, the check_nrpe plugin now accepts switches that specify whether an IPv4 or IPv6 connection should be made to the NRPE daemon. The NRPE daemon has always had the ability to perform checks using IPv6, assuming the plugin it runs supports it. Thanks to Leo Baltus for the patch that made this possible.
IPv6 communication has been tested on Linux (RHEL/CentOS) and is known to work there. It also known to compile on other Unices that we have access to: Solaris 10, AIX 5.3 and 6.1 and HP-UX 11i v1. Feedback on these and other platforms is welcome. Bugs or enhancements (preferably with patches) can be submitted to http://tracker.nagios.org. Other discussion/questions can be sent to the mailing lists or http://support.nagios.com/forum.
