Re: Good VPN for Ubuntu?
Don't use any free VPNs. They are slow, and they usually log the sites you visit, or inject adverts, etc. Also don't use a VPN with servers located in the USA (or similar privacy invasive countries), because of sh*t laws that allow the VPN company to log what goes through their servers. In general, I'd highly recommend a Swedish VPN, for example iPreditor, Anonine, VPNTunnel, or Mullvad. I use BTGuard myself (it's servers are located in Canada and Germany, although I never use the Canadian servers because of poor privacy laws) for torrents and casual browsing, and although it has decent speed and great up-time, the customer service is crappy (overall it's pretty good).
And yes, you should never use PPTP for any VPN.
The whole thing is so patently infantile, so foreign to reality, that to anyone with a friendly attitude to humanity it is painful to think that the great majority of mortals will never be able to rise above this view of life.
