Afin d’effectuer l’installation de NRPE sur un NAS Terramaster, il faudra au pr\u00e9alable d\u00e9j\u00e0 avoir proc\u00e9d\u00e9 \u00e0 l’installation d’un gestionnaire de paquet. Tuto ici<\/a>.<\/p>\n\n\n\n

Dans un premier temps, il faut t\u00e9l\u00e9charger les pr\u00e9requis ainsi que le package NRPE, les plugins nagios et cr\u00e9er l’utilisateur nagios :<\/p>\n\n\n\n

opkg update\nopkg install  autoconf gcc glibc libmcrypt make openssl wget snmp-utils\ncd \/tmp\/\nwget https:\/\/nagios-plugins.org\/download\/nagios-plugins-2.3.3.tar.gz --no-check-certificate\nwget https:\/\/github.com\/NagiosEnterprises\/nrpe\/releases\/download\/nrpe-4.0.2\/nrpe-4.0.2.tar.gz \ntar -xvzf nrpe-4.0.2.tar.gz\ncd nrpe-4.0.2\/\nuseradd -d \/usr\/local\/nagios nagios\npasswd nagios<\/code><\/pre>\n\n\n\n
Une fois le mot de passe de l’utilisateur Nagios configur\u00e9, il faut installer le package. Les NAS terramaster ne poss\u00e9dant pas par d\u00e9faut de gestionnaire de paquet, j’ai install\u00e9 Entware avec lequel je n’ai pas trouv\u00e9 la fa\u00e7on de r\u00e9pondre au pr\u00e9requis SSL, j’ai donc d\u00e9sactiv\u00e9 celui-ci pour l’installation de NRPE :<\/p>\n\n\n\n
.\/configure -enable-command-args -disable-ssl<\/code><\/pre>\n\n\n\n
V\u00e9rifier que cela s’effectue sans erreur, puis :<\/p>\n\n\n\n
make all\nmake install-plugin\nmake install-daemon\nmake install-groups-users\nmake install-config<\/code><\/pre>\n\n\n\n
Nous passons maintenant \u00e0 l’installation des plugins :<\/p>\n\n\n\n
cd ..\ntar -xvzf nagios-plugins-2.3.3.tar.gz\ncd nagios-plugins-2.3.3\/\n.\/configure --build=aarch64-unknown-linux-gnu\n\nmake\nmake install\nchown nagios:nagios \/usr\/local\/nagios\/libexec\/*<\/code><\/pre>\n\n\n\n
Pour la commande pr\u00e9c\u00e9dente make install<\/strong> j’ai personnellement eu un retour en erreur et n’ayant pas r\u00e9ussi a corriger l’erreur, je l’ai donc ignor\u00e9 :<\/p>\n\n\n\n
make install -i<\/code><\/pre>\n\n\n\n
Pour lancer NRPE en mode daemon, il faut ex\u00e9cuter la commande suivante :<\/p>\n\n\n\n
\/usr\/local\/nagios\/bin\/nrpe -c \/usr\/local\/nagios\/etc\/nrpe.cfg -4 -d<\/code><\/pre>\n\n\n\n
Pour d\u00e9marrer le service au d\u00e9marrage du NAS :<\/p>\n\n\n\n
crontab -e\n@reboot \/usr\/local\/nagios\/bin\/nrpe -c \/usr\/local\/nagios\/etc\/nrpe.cfg -4 -d<\/code><\/pre>\n\n\n\n
Le SSL \u00e9tant d\u00e9sactiv\u00e9, depuis le serveur Nagios il est possible d’attaquer le NAS avec l’option -n (ignorer le SSL) :<\/p>\n\n\n\n
check_nrpe -H XXX.XXX.XXX.XXX -n<\/code><\/pre>\n\n\n\n
Le fichier de configuration de NRPE : \/usr\/local\/nagios\/etc\/nrpe.cfg<\/strong><\/p>\n\n\n\n
BONUS<\/strong>
Je me suis \u00e9galement permis de r\u00e9diger un script permettant de le lancer \u00e0 la mani\u00e8re de initd :<\/p>\n\n\n\n
nano \/etc\/init.d\/nrpe\n\n#!\/bin\/sh\nconfigfile=\/usr\/local\/nagios\/etc\/nrpe.cfg\nRETVAL=0\nnrpe=\/usr\/local\/nagios\/bin\/nrpe\n\nstart() {\n        echo -n \"Starting nrpe: \"\n        $nrpe -c $configfile -4 -d\n        echo \"done\"\n}\n\nstop() {\n        echo -n \"Shutting down nrpe services: \"\n        ps -ef | grep nagios | awk  '{print $2}' | xargs kill -9 >&\/dev\/null\n        echo \"done\"\n}\n\nrestart() {\n        stop\n        start\n}\n\ncase \"$1\" in\n  start)\n        start\n        ;;\n  stop)\n        stop\n        ;;\n  restart)\n        restart\n        ;;\n  *)\n        echo \"Usage: $0 {start|stop|restart}\"\n        exit\nesac\n\nexit $?<\/code><\/pre>\n\n\n\n
Note : Le plugin check_users ne fonctionne pas. Celle-ci devant se baser sur la commande who<\/strong> qui semble ne pas fonctionner sur le NAS.<\/p>\n","protected":false},"excerpt":{"rendered":"
