VPS has been around for quiet sometime, and, If only I knew it earlier, I wouldn’t gave justhost.com people my money this year for their crappy server 
.
Anyways, I got myself a VPS a week ago. before I decided to get one, I was actually seeking for a VPN provider. and when I googled, the term VPS keeps coming on to my screen….so I decided to give it a click…then I got a VPS from rockmyweb.net, nice speed, nice configuration, and cheap.
There are a lot of people talks about setup a VPN in VPS, but those threads are soooo long…after 2 days, I found this http://vpsnoc.com/blog/how-to-install-openvpn-on-a-debianubuntu-vps-instantly/.
This is quick and dirty. and there are a few things I need to modify here for rockmyweb.net hosted VPS, and I use ubuntu for my OS.
Requirement:
A VPS
NAT is enable on your server
Able to create tun nod
This script gives you one cert for you to connect to VPN, for multiple user, see openvpn docs. it’s just a matter of running ./build-key
make sure you have /dev/net/tun
normally you don’t, so you need to create one with root privilege.
mknod /dev/net/tun c 10 200
and you can make sure you have nat support
root@znxf:~# iptables -t nat -L
This usually gives you an empty list, but we know that nat is working(support staff says otherwise, but well, it’s working).
If you see a error message instead, you’ll need to contact support.
Chain PREROUTING (policy ACCEPT)

Chain POSTROUTING (policy ACCEPT)

Chain OUTPUT (policy ACCEPT)

After you ran this script, you should have keys.tgz in your root folder. Move it to your ftp and download it to your computer, or scp it or whatever.

Start openvpn-gui, right click the tray icon go to vpn and click connect

Now you can download the keys and unpack it to use with Tunnelblick(Mac), or other VPN clients.

check the spec, they said it supports only 10.4…..oh well….
