Nagios Plugins 2.1.0 Released

The Nagios Plugins Development Team is proud to announce that nagios-plugins 2.1.0 has been released and is available for download.

As promised, both the findbin and timeout_state branches have included in this release. The nasty awk script for perl plugin paths has been removed and replaced with the functionality of FindBin.  Enhancements to the timeout (-t) switch were included in the timeout_state branch.  See below for details:

-t <interval>:<state>

Interval is a positive integer.
State is case insensitive and one of:
State name: ok/warning/critical/unknown
Or stateid: 0/1/2/3

For example:
-t 5:0 = 5 seconds timeout with state ok
-t :warning = default timeout with state warning
-t 5 = 5 second timeout with default state

Additionally, check_http now supports chunked-encoded pages, check_radius now supports the FreeRADIUS Client library, and  check_snmp now support IPv6.

There were many other small fixes from coverity and our fantastic community, as well as a large number of smaller enhancements,  bug fixes, localization fixes, and typo corrections.
