Freepbx Production Install Guide (RHEL v6, Asterisk v11+, Freepbx v2.11+)

Sections: 

Asterisk 11Changes in this guide include Asterisk 11 which requires at least FreePBX v2.11.  Also cdr_mysql module has been deprecated so FreePBX 2.11 adds support for the ODBC method. This install guide adds configurations to enable the new method.  You can continue to use the old method for as long as the cdr_mysql module is included in Asterisk and still functional.

Tested on CentOS 6.4

How to Install OpenVPN and PPTP on RHEL v6

Sections: 

OpenVPNThis procedure can be used to install OpenVPN and/or PPTP VPN access on a Redhat Enterprise Linux v6 server or OpenVZ RHEL v6 virtual server.  For OpenVZ you also require root access to the physical server or you need your service provider to enable virtual server access to tun and ppp on the physical server for you. This install procedure was tested on CentOS v6 using the 64bit distribution.  I have not tried on v5 or 32bit distribution.  For pptp on an OpenVZ virtual server I believe your OS needs to be the same bit type as the physical server.  Ie. if the OpenVZ physical server is 64bit then your virtual server OS must also be 64bit in order for pptp to work

Hardening FreePBX

Sections: 

Hardening FreePBXThis script is a highly modified version of the AsteriskNOW hardening script a copy of which is here.  Some things were added.  Some were changed.  Some things were taken out.  Most importantly, it has been updated to work with newer versions of FreePBX where all the settings that used to be in amportal.conf are now in the Asterisk MySQL database.  As such, it is not compatible with older versions of FreePBX (anything before v2.9) which use the amportal.conf file.

Install Fail2ban for Asterisk from RPM

Sections: 

Fail2ban

This procedure is what I consider the simplest possible fail2ban install procedure because it installs from RPM.  The most up to date RPM is currently found on the EPEL repository.

OpenSIPS and Control Panel Install Guide

OpenSIPSThis install guide was tested using the Redhat Enterprise Linux v5 distribution known as CentOS . 

 

Most of the install procedures for OpenSIPS assume Debian.  I prefer working with RHEL which is the reason for this install procedure.  This guide should work on Debian with some minor modifications but I haven't tried.

Replace TFTP with FTP for SIP phone configuration

Sections: 

These are my notes on how I replace TFTP with FTP for Aastra SIP phone configuration files on a Redhat Enterprise Linux server.  With the TFTP port exposed to the internet and no IP restrictions for remote phone configuration the directory is wide open. This makes it easy for someone to obtain extension passwords.
