This 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

This 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.

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.

This 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.

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.
