hello everybody
i want run a vpn service , now i have questions that i ask you help me please?

1 - how much ram needed for linux vps run vpn ?
2- whitch program better to setup on vps ? and how ?
3- with os you know better ?

so many thanks

Running a VPN server isn't very memory intense, but the amount of RAM you need depends on the number of concurrent VPN connections you want to be able to support. So up to how many people will use your VPN service at the same time?

The two most common VPN servers offered by VPN providers are OpenVPN and PPTP. OpenVPN is better in many ways (and much more secure), but some clients only support PPTP, so it seems to be a good idea to offer it as well.

I'd use Linux as the OS for your VPN server. As there are client programs for pretty much each and every OS, your customers can connect no matter which OS they have.

Check out some websites of popular VPN services. You'll get many clues about what you'll have to set up!

Interesting Question from the Standpoint I was asking somebody about VPN's and here we are. So here's a HOWTO section from OPENVPN (http://openvpn.net/index.php/open-source/documentation/howto.html).
