Prerequisites

NRPE Server

On RPM-Based distribution, you can use the centreon-nrpe3-daemon package deploying a preconfigured version of the NRPE Server.

Most of the Linux distributions provide a NRPE package you can deploy using the system package default manager. When using these, it's important to modify following directives in the config files:

• allowed_hosts

[...]
# ALLOWED HOST ADDRESSES
# This is an optional comma-delimited list of IP address or hostnames
# that are allowed to talk to the NRPE daemon. Network addresses with a bit mask
# (i.e. 192.168.1.0/24) are also supported. Hostname wildcards are not currently
# supported.
allowed_hosts=X.X.X.X,X.Y.Z.V
[...]

• dont_blame_nrpe

[...]
# ALLOWED HOST ADDRESSES
# This is an optional comma-delimited list of IP address or hostnames
# that are allowed to talk to the NRPE daemon. Network addresses with a bit mask
# (i.e. 192.168.1.0/24) are also supported. Hostname wildcards are not currently
# supported.
dont_blame_nrpe=1
[...]

Important note: the NASTY_METACHARS parameter should be left as its default value. Modifying it might open serious security hole and RCE exploitation from an attacker.
