I am looking at a few options but would liek to know any recomendations.
I am setting up two servers for the one extranet website (if seperate datacenters for redundentcy) will point the one domain name to both so if one is down does not mater.
The users will be loading their computers via either a usb stick or live cd to a linux image with a browser in kiosk mode. In booting up it also needs to connect to a VPN on (one of) the server with the website on it.
The VPN will give the user a static local IP (the users details will be built into their image) and the website will automaticly log them in because of this static ip.
How can this be done?
I have looked at Openvpn that looks like it can give static ips to users, set to login when booting up but this will then mean I will need openvpn on both servers which is fine but then will need to purchase accounts for the same users twice to allow to be setup on the other server as well?
I could look to do something like use a hosed service (maybe openvpn hosted?) to do the same but on my servers install client so that they then connect to ther vpn service - can't risk hosted service going down though?
Anyway to outline goal is the have users access website with automatic login via their ip, and access to website only from vpn - remembering that its a opencd operating system.
