Do I need Ports Opened on Server for NRPE Agent Install

Trying to get NRPE agents installed on our production machines. SA's are telling me that the fullinstall script for that process needs to go out to RPMForge and that they do not allow that network traffic
Code: Select all
#!/bin/sh
##########################################
# INSTALL YUM REPOS
##########################################
. ./init.sh
# See if we need to install RPMForge...
if ! rpm -q rpmforge-release &>/dev/null; then
echo "Enabling RPMForge repo..."
(
cd /tmp
URL=$(curl -s http://repoforge.org/use/ | grep -o "http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-[0-9.-]\+.$dist.rf.$basearch.rpm")
curl -L -O "$URL"
rpm -Uvh rpmforge-release*.rpm
rm rpmforge-release*.rpm
)
yum check-update
fi
Can I get an explanation why I need to open up traffic to that site?
Thanks.

Certainly there are many ways to install the NRPE packages and plugins.
In our easy install script you are using we require some items from the rpmforge repo.
However you could install the packages directly through YUM, the packages you will need are nagios-plugins-nrpe and nrpe
One thing to note though is it won't come pre-configured to work, you might need to find where it installed the plugins, change the paths, manually add the allowed IP's etc..

Thanks, is there a default dir it will put the configs? Do you know the name of the config files for NRPE by any chance?

The default is nrpe.cfg however it can also include configs of other names...

Scott, I am getting errors when I try to install:
# rpm -ivh nagios-nrpe-2.5.2-1.el5.rf.x86_64.rpm
warning: nagios-nrpe-2.5.2-1.el5.rf.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 6b8d79e6
error: Failed dependencies:
nagios-plugins is needed by nagios-nrpe-2.5.2-1.el5.rf.x86_64
Which NRPE and NRPE plugins should I be downloading/installing?
Thanks.

Has another dependency
Yum is not detecting those packages so I cannot install them.

Yum list does not have any knowledge of perl(Net::SNMP) or fping.

This is why our fullinstall script needs network access, so it can go out to the repositories and get the required packages...
