 +====== Install NRPE On A Target Machine ======
 +
 +**ON THE TARGET MACHINE (as root):**
 +
 +  groupadd -g 213 nagios
 +  useradd -u 213 -d /dev/null -s /bin/false -g nagios nagios
 +
 +Install nagios via SBo (Required by Nagios-plugins)
 +
 +Install nagios-plugins via SBo (Required by NRPE)
 +
 +Install nrpe via SBo
 +
 +Ignore the xinetd stuff, you have to run NRPE as a daemon on Slackware (unless you want to go through the headache of replacing inetd with xinetd)
 +
 +So, start NRPE in Daemon mode:
 +  chmod 755 /etc/rc.d/rc.nrpe
 +  /etc/rc.d/rc.nrpe start
 +
 +Test NRPE
 +  /usr/libexec/nagios/check_nrpe -H localhost
 +  NRPE v2.15
 +  
 +  /usr/libexec/nagios/check_nrpe -H localhost -c check_users
 +  USERS OK - 1 users currently logged in |users=1;5;10;0
 +
 +Add your Nagios server's IP into the allowed_hosts list:
 +  vi /etc/nagios/nrpe.cfg
 +   allowed_hosts=127.0.0.1,192.168.1.77  (WHERE: 192.168.1.77 is the IP of your Nagios server)
 +
 +  chown nagios:nagios /etc/nagios/nrpe.cfg
 +
 +-----
 +**ON THE NAGIOS SERVER MACHINE:**
 +
 +Add the client machine into one of the .cfg files
 +
 +I did this:
 +  vi /etc/nagios/nagios.cfg
 +ADD:
 + # Definitions for monitoring a linux machine
 + cfg_file=/etc/nagios/objects/linux.cfg
 +
 +  chown nagios:nagios /etc/nagios/nagios.cfg
 +
