Can't find any free VPN provider for Ubuntu. I tried looking into old questions but they seem to be outdated.
Another vpn provider's services that work on Ubuntu are those by a company called Securitykiss. However, the free user is only allowed 300 mb per day, but this may be enough if you are using it in a cyber cafe, for example, to secure your connection.
Before you can follow either of these sets of instructions, however, you need to get a configuration generated for Linux based systems from here and then log on to the client area here and download your package which contains further configuration details.
Securitykiss takes a bit to setup and is limited to 300mb for the free user, but is an example of a 'free' vpn service, of which there are very few 'free' examples out there.
I have just been experimenting with it and wanted to bring it to the attention of the community, as it does work successfully on Ubuntu and the instructions on the site are tailored to Ubuntu so I thought it might be of interest.
If you mean VPN Clients check this:
PPTP (Microsoft VPN)
sudo apt-get install network-manager-pptp
sudo apt-get install network-manager-vpnc
sudo apt-get install network-manager-openvpn
If you mean VPN Servers check this:
Please do not use a free VPN provider. He will sell your data, what else is his source of income?
Have a look at PrivacyTools for a list with recommendations (paid).
Using a VPN will not keep your browsing habits anonymous, nor will it add additional security to non-secure (HTTP) traffic.
If you are looking for anonymity, you should use the Tor Browser instead of a VPN.
If you're looking for added security, you should always ensure you're connecting to websites using encrypted DNS and HTTPS. A VPN is not a replacement for good security practices.
Our recommended providers are outside the US, use encryption, accept Bitcoin, support OpenVPN, and have a no logging policy. Read our full list of criteria for more information.
the most popular choice is ProtonVPN.
