+#  Sample NRPE Config File
+#
+#  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.

+# LOG FACILITY
+# The syslog facility that should be used for logging purposes.

+# LOG FILE
+# If a log file is specified in this option, nrpe will write to
+# that file instead of using syslog.

+# DEBUGGING OPTION
+# This option determines whether or not debugging messages are logged to the

+
+
+
+# PID FILE
+# The name of the file in which the NRPE daemon should write it's process ID

+# supported.
+#
+# 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.

+# COMMAND ARGUMENT PROCESSING
+# This option determines whether or not the NRPE daemon will allow clients

+#
+# *** ENABLING THIS OPTION IS A SECURITY RISK! ***

+# This option determines whether or not the NRPE daemon will allow clients

+# $(...).  This option only works if the daemon was configured with both
+# the --enable-command-args and --enable-bash-command-substitution configure

+# 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 allowing
+# 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

+# MAX COMMANDS
+# This specifies how many children processes may be spawned at any one
+# time, essentially limiting the fork()s that occur.

+# 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
+
+
+
+# CONNECTION TIMEOUT
+# This specifies the maximum number of seconds that the NRPE daemon will
+# wait for a connection to be established before exiting. This is sometimes
+# seen where a network problem stops the SSL being established even though
+# all network sessions are connected. This causes the nrpe daemons to
+# accumulate, eating system resources. Do not set this too low.
+
+connection_timeout=300
+
+
+
+# WEAK 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

+
+
+# SSL/TLS OPTIONS
+# These directives allow you to specify how to use SSL/TLS.
+
+# SSL VERSION
+# This can be any of: SSLv2 (only use SSLv2), SSLv2+ (use any version),
+#        SSLv3 (only use SSLv3), SSLv3+ (use SSLv3 or above), TLSv1 (only use
+#        TLSv1), TLSv1+ (use TLSv1 or above), TLSv1.1 (only use TLSv1.1),
+#        TLSv1.1+ (use TLSv1.1 or above), TLSv1.2 (only use TLSv1.2),
+#        TLSv1.2+ (use TLSv1.2 or above)
+# If an "or above" version is used, the best will be negotiated. So if both
+# ends are able to do TLSv1.2 and use specify SSLv2, you will get TLSv1.2.
+# If you are using openssl 1.1.0 or above, the SSLv2 options are not available.
+
+#ssl_version=SSLv2+
+
+# SSL USE ADH
+# This is for backward compatibility and is DEPRECATED. Set to 1 to enable
+# ADH or 2 to require ADH. 1 is currently the default but will be changed
+# in a later version.
+
+#ssl_use_adh=1
+
+# SSL CIPHER LIST
+# This lists which ciphers can be used. For backward compatibility, this
+# defaults to 'ssl_cipher_list=ALL:!MD5:@STRENGTH' for < OpenSSL 1.1.0,
+# and 'ssl_cipher_list=ALL:!MD5:@STRENGTH:@SECLEVEL=0' for OpenSSL 1.1.0 and

+
+# SSL USE CLIENT CERTS
+# This options determines client certificate usage.
+# Values: 0 = Don't ask for or require client certificates (default)
+#         1 = Ask for client certificates
+#         2 = Require client certificates
+
+#ssl_client_certs=0
+
+# SSL LOGGING
+# This option determines which SSL messages are send to syslog. OR values
+# together to specify multiple options.
+
+# Values: 0x00 (0)  = No additional logging (default)
+#         0x01 (1)  = Log startup SSL/TLS parameters
+#         0x02 (2)  = Log remote IP address
+#         0x04 (4)  = Log SSL/TLS version of connections
+#         0x08 (8)  = Log which cipher is being used for the connection
+#         0x10 (16) = Log if client has a certificate
+#         0x20 (32) = Log details of client's certificate if it has one

+
+# 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...
+# This is by far the most secure method of using NRPE

+# The following examples allow user-supplied arguments and can

+# command arguments *AND* the dont_blame_nrpe directive in this
+# config file is set to '1'.  This poses a potential security risk, so
+# make sure you read the SECURITY file before doing this.
