OpenVPN is flexible in other ways as well, allowing endpoints to authenticate using either PKI-style certificates or P2P-style pre-shared key authentication. In this case I want to implement a client. The software is capable of implementing either a VPN server or a VPN client. It is built heavily on the OpenSSL library, and is largely a modification of the SSL/TLS protocol. OpenVPN is an open source VPN daemon written by James Yonan. Since there is no TunnelBear client for Linux (and the same is true of a number of other VPN services I would wager), I will have to set up the VPN client myself using a generic VPN software like OpenVPN. Cypherpunks will be equally familiar with the solution to this vulnerability, which is to use end-to-end encryption via a VPN. People who are in the Cypherpunk/Internet privacy community will be familiar with the Tor exit node vulnerability, where data is completely decrypted as it leaves the exit node and can thus be intercepted if the exit node is controlled by a hostile entity. My next step is to add end-to-end encryption with a VPN. So far I’ve managed to combine Tor with proxychains so that after a packet leaves the Tor network, it goes through a series of anonymous SOCKS proxies before reaching its destination (I will talk about this part of the project in another post). in combination to minimize the chances of being deanonymized. This involves a philosophy of complete overkill, where a user combines tools like Tor, multiple VPNs, multiple SOCKS proxies, anti-fingerprinting techniques, etc. One of the projects I’ve been working on lately is creating a system where I can be as anonymous as possible while doing hacky stuff on the Internet through Tails. The other reason is just the simple fact that the client won’t run on Linux. That’s one reason why I wanted to find an alternative to the stock TunnelBear client. It’s not very customizable and it tends to stop working at random times, and when it gets disconnected, it takes a really long time to reconnect, if it’s able to reconnect at all. The actual VPN client software, however, still leaves much to be desired. I do have to turn it off when posting to certain sites like 4Chan that interpret VPN traffic as spam or abusive content, which is a major pain in the ass, but other than that it serves its function rather well. TunnelBear is a paid VPN, and for the most part I like it. Never ever use one under any circumstances. Seriously, free VPNs are a joke, a literal scam. The only difference is which companies are collecting your data. And due to the magic of subpoenas and B2B Big Data marketing, that data is instantly available to governments and corporations whenever they want it, so in practice using a free VPN isn’t any safer than using no VPN at all. I swear by paid VPNs as opposed to free VPNs, because free VPNs almost universally collect massive amounts of data on you and use that data to bombard you with ads. There are a lot of VPN services out there, but I will focus on TunnelBear since I’d like to be able to get into the nitty-gritty details of my experience rather than having to be vague and general in an effort to be widely applicable. I’m going to talk about my personal experience establishing TunnelBear service through OpenVPN. TunnelBear is a paid VPN service that provides both end-to-end VPN encryption and anonymous proxying, using AES-256 encryption for all connections, and collects only a bare minimum of data from customers. If you still are having issues logging in, please try resetting your password.In this article I want to talk about one of my tech adventures from shortly after I went on vacation, which is that of getting OpenVPN up and running and using it to contact the TunnelBear servers. On macOS, you may see the following error message: (-999) Cancelled.Ĭheck to make sure you are using the correct email and password combination. This can typically be resolved by resetting the Windows Firewall to its default settings. On Windows, you may see the following error message: (-1009) No Internet Connection. Please try disabling any firewalls/security software that you may have enabled to see if you can now log in. Some third-party programs may interfere with your ability to get logged into TunnelBear. Please try logging in using another network if you have one available. If you are connecting from a more restrictive network, or a location where heavier censorship is enforced, you may run into issues with logging in. There are several reasons why you may experience login issues:
