PacketFence Installation:
yum repository: Make sure your system is up to date and your yum database is updated: yum update

Some PacketFence dependencies are available through ( so you need to configure YUM to use it.
First import the DAG RPM GPG key:
rpm -import
Then install the latest version of the RPMForge package (
rpm -i rpmforge-release-0.5.2-2.el5.rf.i386.rpm
In order to use the repository, just create a file named /etc/yum.repos.d/PacketFence.repo with the following content:
name=PacketFence Repository
Once the repository is defined, you can install PacketFence with all it's dependencies, and the required external services (DNS server, Database server, DHCP server, RADIUS server) using:
yum groupinstall --enablerepo=PacketFence,rpmforge “Packetfence-complete”
Or, if you prefer, to install only the core PacketFence without all the external services, you can use :
yum install --enablerepo=PacketFence,rpmforge packetfence

Execute the installer at /usr/local/pf/ and follow the instructions.
Once completed, PacketFence will be fully installed on your server. You are now ready to configure it.

PacketFence Configuration:
In order to properly begin the configuration of PacketFence, we strongly recommend to execute the configuration script located at /usr/local/pf/ This script will guide you through the process of creating a working PacketFence configuration file that is suitable to your needs.

Keep in mind that the resulting PacketFence configuration will be located in /usr/local/pf/conf/pf.conf, and it can always be adjusted by hand afterward.

PacketFence provides a web-based administration interface for easy configuration and operational management. In order to access the interface you need to create an administrator and a web services account.
You need to encrypt the new password in the admin.conf file with htpasswd:
htpasswd /usr/local/pf/conf/admin.conf admin
Then again for webservice:
htpasswd /usr/local/pf/conf/admin.conf webservice

Once PacketFence is started, administration interface is available at: https://ipaddress:1443/
