FastPCRF (BRAS integration by RADIUS)

PCRF provides proxying requests from fastDPI to the Radius server. It is a part of the standard Stingray Service Gateway installation package, but if necessary, it can be used as a dedicated server.

In order to run PCRF you can use the following hardware or virtual machines matching the following characteristics:

1. CPU 2.5 GHz, 1 pcs
2. RAM 512 MB - 1 GB
3. HDD 50 GB - 250 GB
4. Operating system Cent OS 8.5, VEOS
5. NIC ranging from 10 Mb/s

1. Install the Network Time Protocol daemon

   yum install chrony -y
   systemctl restart chronyd
   timedatectl

   When entering the timedatectl command, the System clock synchronized parameter must be set to yes

2. Add vasexperts repository

   rpm --import http://vasexperts.ru/centos/RPM-GPG-KEY-vasexperts.ru
   rpm -Uvh http://vasexperts.ru/centos/6/x86_64/vasexperts-repo-2-1.noarch.rpm

3. Install the fastPCRF

   yum install fastpcrf

4. Make sure the service is running

   service fastpcrf start

5. Сonfigure fastpcrf service to run at startup

   systemctl enable fastpcrf

6. Open firewall ports in order to access the fastPCRF and Radius servers

   firewall-cmd --permanent --zone=public --add-port=22/tcp
   firewall-cmd --permanent --zone=public --add-port=3799/udp
   firewall-cmd --permanent --zone=public --add-port=29002/tcp

and restart firewall for the rules to take effect

firewall-cmd --reload

1. Disable selinux ¹⁾

   setenforce 0
   vi /etc/selinux/config
   SELINUX=disabled

You can get these utilities from the server where fastDPI is installed.
The utility files are located in /usr/sbin/.

1. Copy the utilities to the home directory

   cp /usr/sbin/fdpi_cli /home/vasexpertsmnt
   cp /usr/sbin/fdpi_ctrl /home/vasexpertsmnt

2. Move these files to the server where fastPCRF is installed, to /home/vasexpertsmnt

How to use the utility:

fdpi_cli -r 1.1.1.1 dpi config get trace_ip 
fdpi_cli -r 2.2.2.2 pcrf config get verbose
fdpi_ctrl -r 1.1.1.1:29000 list all --bind

Server address – 1.1.1.1 where the fastDPI module is installed.
Server address – 2.2.2.2 where the fastPCRF module is installed.
