Added function to clean the environment before forking. (John Frickson)
ENHANCEMENTS
Added support for optional config file to check_nrpe. With the new SSL
parameters, the line was getting long. The config file is specified with
--config-file= or -f parameters. The config file must look
like command line options, but the options can be on separate lines. It
MUST NOT include --config-file (-f), --command (-c) or --args (-a). If any
options are in both the config file and on the command line, the command line
options are used.
make can now add users and groups using "make install-groups-users" (John Frickson)
Added "nrpe-uninstall" script to the same directory nrpe get installed to (John Frickson)
Updated code so configure && make will work on AIX, HP-UX, Solaris, OS X.
There should be no errors or warnings. Let me know if any errors or
warning appear (John Frickson)
Added command-line option to prevent forking, since some of the init
replacements (such as systemd, etc.) don't want daemons to fork (John Frickson)
Added autoconf macros and additional files to better support multi-platform
config and compile. The default will still set up to install to
/usr/local/nagios but I added a new configure option:
'--enable-install-method='. If is 'opt', everything will
install to '/opt/nagios'. If is 'os', installation will be to O/S-
and distribution-specific locations, such as /usr/sbin, /usr/lib/nagios,
/etc/nagios, and so on.
Added additional init and inetd config files to support more systems,
including SuSE, Debian, Slackware, Gentoo, *BSD, AIX, HP-UX, Solaris, OS X.
Added listen_queue_size as configuration option (Vadim Antipov, Kaspersky Lab)
Reworked SSL/TLS. See the README.SSL.md file for full info. (John Frickson)
Added support for version 3 variable sized packets up to 64KB. nrpe will
accept either version from check_nrpe. check_nrpe will try to send a
version 3 packet first, and fall back to version 2. check_nrpe can be forced
to only send version 2 packets if the switch -2 is used. (John Frickson)
Added extended timeout syntax in the -t : format. (ABrist)
