2 # Sample NRPE Config File

8 # This is a sample configuration file for the NRPE daemon. It needs to be
9 # located on the remote host that is running the NRPE daemon, not the host
10 # from which the check_nrpe client is being executed.
11 #############################################################################
15 # The name of the file in which the NRPE daemon should write it's process ID
16 # number. The file is only written if the NRPE daemon is started by the root
17 # user and is running in standalone mode.
19 pid_file=/var/run/nrpe.pid
24 # Port number we should wait for connections on.
25 # NOTE: This must be a non-priviledged port (i.e. > 1024).
26 # NOTE: This option is ignored if NRPE is running under either inetd or xinetd
33 # Address that nrpe should bind to in case there are more than one interface
34 # and you do not want nrpe to bind on all interfaces.
35 # NOTE: This option is ignored if NRPE is running under either inetd or xinetd
37 #server_address=192.168.1.1
42 # This determines the effective user that the NRPE daemon should run as.
43 # You can either supply a username or a UID.
45 # NOTE: This option is ignored if NRPE is running under either inetd or xinetd
47 nrpe_user=nrpe,admin,root
52 # This determines the effective group that the NRPE daemon should run as.
53 # You can either supply a group name or a GID.
55 # NOTE: This option is ignored if NRPE is running under either inetd or xinetd
61 # ALLOWED HOST ADDRESSES
62 # This is an optional comma-delimited list of IP address or hostnames
63 # that are allowed to talk to the NRPE daemon.
65 # Note: The daemon only does rudimentary checking of the client's IP
66 # address. I would highly recommend adding entries in your /etc/hosts.allow
67 # file to allow only the specified host to connect to the port
68 # you are running this daemon on.
70 # NOTE: This option is ignored if NRPE is running under either inetd or xinetd
72 allowed_hosts=127.0.0.1,138.96.250.127,138.96.250.129,87.98.251.120
76 # COMMAND ARGUMENT PROCESSING
77 # This option determines whether or not the NRPE daemon will allow clients
78 # to specify arguments to commands that are executed. This option only works
79 # if the daemon was configured with the --enable-command-args configure script
82 # *** ENABLING THIS OPTION IS A SECURITY RISK! ***
83 # Read the SECURITY file for information on some of the security implications
84 # of enabling this variable.
86 # Values: 0=do not allow arguments, 1=allow command arguments
93 # This option allows you to prefix all commands with a user-defined string.
94 # A space is automatically added between the specified prefix string and the
95 # command line from the command definition.
97 # *** THIS EXAMPLE MAY POSE A POTENTIAL SECURITY RISK, SO USE WITH CAUTION! ***
99 # Execute restricted commmands using sudo. For this to work, you need to add
100 # the nagios user to your /etc/sudoers. An example entry for alllowing
101 # execution of the plugins from might be:
103 # nagios ALL=(ALL) NOPASSWD: /usr/lib/nagios/plugins/
105 # This lets the nagios user run all commands in that directory (and only them)
106 # without asking for a password. If you do this, make sure you don't give
107 # random users write access to that directory or its contents!
109 # command_prefix=/usr/bin/sudo
114 # This option determines whether or not debugging messages are logged to the
116 # Values: 0=debugging off, 1=debugging on
123 # This specifies the maximum number of seconds that the NRPE daemon will
124 # allow plugins to finish executing before killing them off.
131 # This specifies the maximum number of seconds that the NRPE daemon will
132 # wait for a connection to be established before exiting. This is sometimes
133 # seen where a network problem stops the SSL being established even though
134 # all network sessions are connected. This causes the nrpe daemons to
135 # accumulate, eating system resources. Do not set this too low.
137 connection_timeout=300
141 # WEEK RANDOM SEED OPTION
142 # This directive allows you to use SSL even if your system does not have
143 # a /dev/random or /dev/urandom (on purpose or because the necessary patches
144 # were not applied). The random number generator will be seeded from a file
145 # which is either a file pointed to by the environment valiable $RANDFILE
146 # or $HOME/.rnd. If neither exists, the pseudo random number generator will
147 # be initialized and a warning will be issued.
148 # Values: 0=only seed from /dev/[u]random, 1=also seed from weak randomness
150 #allow_weak_random_seed=1
154 # INCLUDE CONFIG FILE
155 # This directive allows you to include definitions from an external config file.
157 #include=<somefile.cfg>
161 # INCLUDE CONFIG DIRECTORY
162 # This directive allows you to include definitions from config files (with a
163 # .cfg extension) in one or more directories (with recursion).
165 #include_dir=<somedirectory>
166 #include_dir=<someotherdirectory>
170 # COMMAND DEFINITIONS
171 # Command definitions that this daemon will run. Definitions
172 # are in the following format:
174 # command[<command_name>]=<command_line>
176 # When the daemon receives a request to return the results of <command_name>
177 # it will execute the command specified by the <command_line> argument.
179 # Unlike Nagios, the command line cannot contain macros - it must be
180 # typed exactly as it should be executed.
182 # Note: Any plugins that are used in the command lines must reside
183 # on the machine that this daemon is running on! The examples below
184 # assume that you have plugins installed in a /usr/local/nagios/libexec
185 # directory. Also note that you will have to modify the definitions below
186 # to match the argument format the plugins expect. Remember, these are
189 # The following examples use hardcoded command arguments...
