This is a stay on up post to How to setup a VPN server on a CentOS VPS straight away same requirements and instructions apply.
Minor delivery point changes were made on the previous CentOS speech to get it effective under Debian and Ubuntu. We might start one single speech which will bed in OpenVPN on most distributions and architectures in prospect.
To bed in issue the following orders logged in as root on your VPS (Give up to this post if you are facing any issues)
wget http://vpsnoc.com/scripts/debian-openvpn.sh
chmod +x debian-openvpn.sh
./debian-openvpn.sh
For any additional issues and pointer please e-mail us at help@vpsnoc.com
You may use and adjust this speech but you see fit, provided that you do not edit the first copyright.
#!/bin/bash
# Quick and soil OpenVPN bed in speech
# Tested on debian 5.0 32bit, openvz minimal debian OS template
# and Ubuntu 9.04 32 bit minimal, must work on 64bit descriptions as well
# Please give up pointer and questions at help@vpsnoc.com
