Ask Slashdot: How To Combat IP-Based Censorship? 103

An anonymous reader writes "For a while now there has been a lot of buzz on a new proposed censorship scheme in Turkey. The government wants to crack down on freedom of speech and other rights by preventing us from accessing any websites it deems unsuitable. The reasons for that could be criticism of the government, pornography and basically anything a politician might dislike (YouTube is blocked for example — I'm not sure about Google, etc., because I'm bypassing the filter). Right now the state is using DNS-based filtering which can be circumvented with OpenDNS or proxy services which everybody knows about in Turkey. On August 22, however, a new scheme will go into effect that uses IP-based filtering. Bypassing this by any means is illegal, but I wanted to get some opinions on how this could be done without having to set up a VPN server outside of Turkey and using it as a private proxy."

    You know, there's not a lot of ways other than VPN and the other ways usually aren't as secure. The last link provided covers most of the bases -- albeit in subpar English. So I guess what I would suggest is you contacting a not-for profit like Garden Networks [wikipedia.org] and ask them to grant Turks the same status as Chinese users in that you don't have to subscribe to use their premium servers. Their gTunnel application seems straight forward and intuitive and appears secure. It appears that users in China, Kuwait and Iran [gardennetworks.org] enjoy it so I imagine you shouldn't have any problems either.

    Furthering that idea, you might pass out "awareness" pamphlets while asking for donations to "keep the internet uncensored" and then pay for your pamphlets and donate the rest of that money to Garden Networks. I don't fully know what level of risk that might entail in Turkey, I certainly would not suggest that to a Chinese citizen.

    I will say that it is conceivably possible for your government to go insane and block ranges of IP addresses so that you cannot access Garden Network's premium servers or Tor nodes ... that would be pretty extensive however.

      This is pretty poor advice. For one, the software is quite crappy (I can't get it to work here in China). More importantly, by using their software you associate with them. Which may already be risky. Then you go as far as to say the OP should help fund this NGO. Enough for the government to classify him as a danger to national security / terrorist / whatever.

      IMHO it's much better to get that $2.99 VPN (I've seen them even cheaper) and claim you just wanted to talk to your Facebook friends abroad than to get involved with these type of NGO's.

      • This is pretty poor advice.

        Well, I apologize, I assure you that I have no affiliation with Garden Networks and, yes, their free service uses Tor -- which I think is largely German based if I'm not mistaken. I would imagine that would be better for Turkish users but who knows. I thought their protocol was novel but if you say they suck in China, I'll take your word on it.

        "Help fund this NGO" is not really what I said. I'm pretty sure I suggested raising awareness and, assuming Garden Networks is giving them free premium service, se

    What about using Tor bridges?

    https://www.torproject.org/docs/bridges [torproject.org]

    This is assuming, of course, that simply using encryption will not put you under suspicion.

      I use it, love it, also love the freenet, but the problem is those are "another net" not "the net". They will help you transfer files past the iron curtain. They will not help you log into youtube and facebook.

      The problem is almost exactly like trying to replace ms office with openoffice.org. Whiners will not be satisfied with "doing about the same thing", they'll used it as a whining point unless they can get it exactly the same down to the pixel and last decimal point.

    A cheap option could be rent a *nix VPS outside of Turkey and setup an SSH server with IP forwarding (in the kernel). You can then use a local machine to open an SSH connection to it and route traffic via the SSH tunnel.

  • Which faction is supporting this?

    • the equivalent of republicans in america - a faction which merges capitalism (corporate capitalism like in america), and religion.

      actually they are not 'supporting' it. they are doing it. due to majority.
      • by couchslug (175151)

        It figures. Ataturk's vision was always in conflict with the real culture of Turkey, and that culture is why it should never be allowed in the EU.

        • by Z00L00K (682162)

          As long as Turkey isn't acknowledging the Armenian genocide they should be kept on ice.

          But the whole region there seems to be poisoned politically. Including Israel.

    Well, obviously then just about anything you do WILL be illegal. Depending on how well this law is enforced, that could be an acceptable risk or not.

    I wanted to get some opinions on how this could be done without having to set up a VPN server outside of Turkey

    In your situation, just about any solution is going to involve outside help from SOMEONE. And an outside VPN is as good a solution as any.

    • by Z00L00K (682162)

      If it's illegal in a country like Turkey you can always get around it using a sufficient amount of bribes.

  • And Turkey wants to join the EU. Don't make me laugh.

    • by xnpu (963139)

      That's why it will be the EU joining Turkey instead.

      The EU needs to court favor with Turkey. The Turks are going to be a serious military and economic force in the coming decades.

    Solution: Vote in a new government. It works for us.

    Not.

  • If you can put with the FAP and LAG there is satellite internet.

  • Run for political office.
  • This is easy and I recommend looking at a very inexpensive service called Tunnelr [tunnelr.com]. Tunnelr offers SSH and OpenVPN tunnels and is located primarily in the United States. Tunnelr also uses the most secure OS on the planet, OpenBSD, so you are fairly safe. However, I would be very careful because the last thing that you want to do is end up in a Turkish prison.

      Turkish people think exactly the same thing for US prisons. At least you don't have to worry about your ass if you drop the soap in Turkish ones.

      • And how do you know this ?

      • by niw3 (1029008)
        Turkish prisons are much better than US prisons, if US prisons are exactly as they are pictured by movies and TV shows. Ironically, you rate Turkish prisons after watching ONE non Turkish movie, which is a well known anti Turkey propaganda everyone is apperantly willing to buy.
  • Using off the shelf hardware, groups of people could pool internet resources to ensure their continued ability to access the internet. Even with a very large mesh network (not just wireless), it would only be a few hops to an internet gateway. This would have the added benefit of providing redundancy for the people involved (e.g. in an area where Comcast and AT&T are the only "physical" ISP's). It would also be imperative not to "oversell" your connection capacity, as this would basically kill the usab

  • Ultrasurf was developed to evade the Great Firewall of China. I would not be surprised if Turkey is getting consultation from China. There is a wired article at http://www.wired.com/magazine/2010/11/ff_firewallfighters/ [wired.com]

    A good starting point for UltraSurf and some of the other options is a consortium of several organizations including the folks behind gTunnel which is at:

    Their web site has not been updated very recently, but I don't know how the individual organizatio
  • Welcome to China!

  • How about switching to the new technology? Some sites have already native IPv6 support, and for others you can use public IPv6->IPv4 proxies. See for instance: http://www.sixxs.net/tools/gateway/ [sixxs.net]
  • While it doesn't change (or answer) the question on how to bypass the filtering, what the poster does not make clear is that the "safe internet" infrastructure that will be enabled by all operators (due to government regulation) will be opt-in. Unless subscribers specifically request that their internet be filtered, their traffic will not even pass through the filtering system, and the Turkish government has specifically stated (believable or otherwise) that they have no intention of making the system manda

    • by unity100 (970058)
      no. the 'opt in' they talk about, is the 'main' package which will keep filtering websites just like they do. the difference is, it will be ip based filtering instead of dns based filtering, and it will be illegal to circumvent it. so basically the 'opt in' just covers the fact that websites will be censored nation-wide, but there will be 2 heavier censored packages.
  • by Krneki (1192201)
    While the VPN is a good solution it is also the most visible if someone is tracking this activities.

    A ssh tunnel is the most discrete and while it is not a solution for everything like VPN, it does cover all you need for web surfing.

    Also you could use something like foxyproxy addon for Firefox and you can tunnel SSH for only the web pages you needs, thus reducing the chances to get caught to the bare minimum.

    And SSH tunnel is the most difficult type of connection for a firewall to block.
  • Turkey is an oppressive regime with little to no regards for its subjects (e.g. Ilisu dam) yet still wishes to join the EU. If you are willing to take some personal risk, you could always contact the EU and complain; although it may be better to find a contact in another EU country to complain on your behalf. And, of course, many "free" EU states see little wrong with censoring the Internet and have plans to do so. If you are prepared to wait a while, more secure systems will become available to by-pass

  • Turkey really, really, really wants to become a member of EU, but there's been several obstacles already, including the state mandated denial of the Armenian Genocide and their less-than-equal treatment of women and other human rights violations. Adding full censorship to the list will make sure life will get better in Turkey as their desire to become an EU member is so strong it just might make them drop this stupid censorship and correct the other 'follies'...

  • I know Slashdot has developed a cultural sense of anything Bitcoin-related as being utter shit, but does anyone follow the development of Namecoin, or think they could help? It's in an alpha stage right now, but as i understand it, the intention is to incorporate dns services in addition to the current simple name registering scheme.
