+# Sample NRPE Config File 
+# Written by: Ethan Galstad (nagios@nagios.org)
+# 
+# Last Modified: 02-23-2006
+#
+# NOTES:
+# This is a sample configuration file for the NRPE daemon.  It needs to be
+# located on the remote host that is running the NRPE daemon, not the host
+# from which the check_nrpe client is being executed.
+#############################################################################
+
+
+# PID FILE
+# The name of the file in which the NRPE daemon should write it's process ID
+# number.  The file is only written if the NRPE daemon is started by the root
+# user and is running in standalone mode.
+
+pid_file=/var/run/nrpe.pid
+
+
+
+# PORT NUMBER
+# Port number we should wait for connections on.
+# NOTE: This must be a non-priviledged port (i.e. > 1024).
+# NOTE: This option is ignored if NRPE is running under either inetd or xinetd
+
+server_port=5666
+
+
+
+# SERVER ADDRESS
+# Address that nrpe should bind to in case there are more than one interface
+# and you do not want nrpe to bind on all interfaces.
+# NOTE: This option is ignored if NRPE is running under either inetd or xinetd
+
+#server_address=192.168.1.1
+
+
+
+# NRPE USER
+# This determines the effective user that the NRPE daemon should run as.  
+# You can either supply a username or a UID.
+# 
+# NOTE: This option is ignored if NRPE is running under either inetd or xinetd
+
+nrpe_user=nagios
+
+
+
+# NRPE GROUP
+# This determines the effective group that the NRPE daemon should run as.  
+# You can either supply a group name or a GID.
+# 
+# NOTE: This option is ignored if NRPE is running under either inetd or xinetd
+
+nrpe_group=nagios
+
+
+
+# ALLOWED HOST ADDRESSES
+# This is an optional comma-delimited list of IP address or hostnames 
+# that are allowed to talk to the NRPE daemon.
+#
+# Note: The daemon only does rudimentary checking of the client's IP
+# address.  I would highly recommend adding entries in your /etc/hosts.allow
+# file to allow only the specified host to connect to the port
+# you are running this daemon on.
+#
+# NOTE: This option is ignored if NRPE is running under either inetd or xinetd

+
+# COMMAND ARGUMENT PROCESSING
+# This option determines whether or not the NRPE daemon will allow clients
+# to specify arguments to commands that are executed.  This option only works
+# if the daemon was configured with the --enable-command-args configure script
+# option.  
+#
+# *** ENABLING THIS OPTION IS A SECURITY RISK! *** 
+# Read the SECURITY file for information on some of the security implications
+# of enabling this variable.
+#
+# Values: 0=do not allow arguments, 1=allow command arguments
+
+dont_blame_nrpe=1
+
+
+# COMMAND PREFIX
+# This option allows you to prefix all commands with a user-defined string.
+# A space is automatically added between the specified prefix string and the
+# command line from the command definition.
+#
+# *** THIS EXAMPLE MAY POSE A POTENTIAL SECURITY RISK, SO USE WITH CAUTION! ***
+# Usage scenario: 
+# Execute restricted commmands using sudo.  For this to work, you need to add
+# the nagios user to your /etc/sudoers.  An example entry for alllowing 
+# execution of the plugins from might be:
+#
+# nagios          ALL=(ALL) NOPASSWD: /usr/lib/nagios/plugins/
+#
+# This lets the nagios user run all commands in that directory (and only them)
+# without asking for a password.  If you do this, make sure you don't give
+# random users write access to that directory or its contents!
+
+# command_prefix=/usr/bin/sudo 
+
+
+
+# DEBUGGING OPTION
+# This option determines whether or not debugging messages are logged to the
+# syslog facility.
+# Values: 0=debugging off, 1=debugging on
+
+debug=0
+
+
+
+# COMMAND TIMEOUT
+# This specifies the maximum number of seconds that the NRPE daemon will
+# allow plugins to finish executing before killing them off.
+
+command_timeout=60
+
+
+
+# WEEK RANDOM SEED OPTION
+# This directive allows you to use SSL even if your system does not have
+# a /dev/random or /dev/urandom (on purpose or because the necessary patches
+# were not applied). The random number generator will be seeded from a file
+# which is either a file pointed to by the environment valiable $RANDFILE
+# or $HOME/.rnd. If neither exists, the pseudo random number generator will
+# be initialized and a warning will be issued.
+# Values: 0=only seed from /dev/[u]random, 1=also seed from weak randomness
+
+#allow_weak_random_seed=1
+
+
+
+# INCLUDE CONFIG FILE
+# This directive allows you to include definitions from an external config file.
+
+#include=<somefile.cfg>
+
+
+
+# INCLUDE CONFIG DIRECTORY
+# This directive allows you to include definitions from config files (with a
+# .cfg extension) in one or more directories (with recursion).
+
+#include_dir=<somedirectory>
+#include_dir=<someotherdirectory>
+include_dir=<%= nagios_nrpe_cfgdir %>/nrpe.d

+
+
+# COMMAND DEFINITIONS
+# Command definitions that this daemon will run.  Definitions
+# are in the following format:
+#
+# command[<command_name>]=<command_line>
+#
+# When the daemon receives a request to return the results of <command_name>
+# it will execute the command specified by the <command_line> argument.
+#
+# Unlike Nagios, the command line cannot contain macros - it must be
+# typed exactly as it should be executed.
+#
+# Note: Any plugins that are used in the command lines must reside
+# on the machine that this daemon is running on!  The examples below
+# assume that you have plugins installed in a /usr/local/nagios/libexec
+# directory.  Also note that you will have to modify the definitions below
+# to match the argument format the plugins expect.  Remember, these are
+# examples only!
+
+# The following examples use hardcoded command arguments...
+
+#command[check_users]=/usr/lib/nagios/plugins/check_users -w 5 -c 10
+#command[check_load]=/usr/lib/nagios/plugins/check_load -w 15,10,5 -c 30,25,20
+#command[check_disk1]=/usr/lib/nagios/plugins/check_disk -w 20 -c 10 -p /dev/hda1
+#command[check_disk2]=/usr/lib/nagios/plugins/check_disk -w 20 -c 10 -p /dev/hdb1
+#command[check_zombie_procs]=/usr/lib/nagios/plugins/check_procs -w 5 -c 10 -s Z
+#command[check_total_procs]=/usr/lib/nagios/plugins/check_procs -w 150 -c 200 
+
+# The following examples allow user-supplied arguments and can
+# only be used if the NRPE daemon was compiled with support for 
+# command arguments *AND* the dont_blame_nrpe directive in this
+# config file is set to '1'...
+
+#command[check_users]=/usr/lib/nagios/plugins/check_users -w $ARG1$ -c $ARG2$
+#command[check_load]=/usr/lib/nagios/plugins/check_load -w $ARG1$ -c $ARG2$
+#command[check_disk]=/usr/lib/nagios/plugins/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$
