In case anyone wondered how to potentially get around this…
- Pay for a server in another country that gives you SSH access
- Create SSH SOCKS tunnel:
ssh -N -D 8008 your-server-ip - Open your browser and set the SOCKS server to
localhost:8008(in Chromium/Firefox you can search for this in Settings)
So, that’s definitely better than nothing, but your browser isn’t the only thing – though these days, it is a very important thing – that talks to the Internet. If, for example, you’re using a lemmy client to read this, I’d bet that it’s good odds that it doesn’t have SOCKS support.
Though I wouldn’t be surprised if someone has made VPN software that intercepts connections and acts as a proxy SOCKS client, which would make it work more like a traditional VPN if you can reach a remote SOCKS server, though maybe with a performance hit.

Yeah, okay, looks like stunnel can do this on Linux. So it’s a thing.
You don’t need a 100% solution, though, to have a pretty big impact on society. Combine technical barriers with it just being easier to not think about what’s going on outside, maybe some chilling effects from legally going after people who do start doing things that you don’t like (viewing websites, spreading information, etc), and you can control people’s information environment a lot. Make using circumvention solutions illegal – okay, maybe you can bypass their system if you don’t get caught, but do you want to risk it? Make creating or spreading circumvention solutions really illegal. Do you want to risk getting in a lot of trouble so that random other person can get unrestricted or unmonitored Internet access?
On that note, I was reading about the way North Korea does it in an article from someone who got out of North Korea. That is about as close as it gets to a 100% solution. Only a few thousand people are authorized to get Internet access. You need to apply to use the Internet with a couple of days lead time. Each pair of computers has a “librarian” monitoring what the Internet user on each side is doing, and every five minutes or so the computer will halt with whatever you were doing on the screen and require fingerprint re-authorization from the “librarian” to continue. Users are not allowed to view pages in Korean, just English and Chinese (I assume because most information out there that you’d have to go outside North Korea to get access to is likely available in either English or Chinese, and they definitely don’t want people seeing anything out of South Korea).
That pretty much screws North Korea in terms of access to information, is a costly solution, but if you place an absolute priority on control of the information environment, North Korea does prove that it’s possible to take a society there.
North Korea does prove that it’s possible to take a society there.
I don’t think NK took themselves there, they were already there when the internet was invented. Easier to limit access to few people when you have draconian measures in place when access becomes possible.
Having a society that already widely has access to one that has extremely limited access is a lot more difficult.
This is a good point that many don’t think about. Even if you could somehow drop hardware and free starlink into North Korea it wouldn’t even matter because the citizens never grew up on internet culture. No one would be able to figure out what to do with it by the time they got caught.
Unfortunately it would be trivial to block an SSH tunnel like this. I recall reading news 10 years ago (maybe even earlier) some foreign journalist tried this at a Beijing hotel room and got shut down in minutes. That was when people are still using PPTP and L2TP protocols to get around censorship, Wireguard and shadowsocks wouldn’t be born for another couple years.
trivial to block an ssh tunnel like this
Far from trivial unless you’re willing to brick ssh completely, or at least cripple a bunch of non-VPN uses for tunneling. Of course it’s trivial to just block ssh outright, or block tunneling above a certain bandwidth. But that would also block, as an example, most remote IDE sessions, loopback-only server management frontends, etc.
The Kremlin could maybe have something set up that looks for accesses to stuff inside Russia from outside Russia, then flag that IP as suspicious as being a VPN endpoint outside Russia.
So, okay, take this scenario:
-
IP A, user inside Russia.
-
IP B, VPS outside Russia.
-
IP C, service inside Russia that state can monitor.
User in Russia on IP A has an SSH tunnel to VPS on IP B with SOCKS that they control.
That’s fine as long as user is only browsing the Internet outside Russia. But if you’re routing all traffic through the VPS and you use any sites in Russia, the Great Russian Firewall can see the following:
-
IP A has a long-running SSH connection to IP B.
-
IP B is accessing stuff in Russia.
You could maybe also do heavier-weight traffic analsysis on top of that if you see 1 and 2, or gather data over a longer period of time, but seeing 1 and 2 alone are probably enough to block IP A to IP B connections.
That can be defeated by using two external VPSes, opening an SSH tunnel to the first one, and then talking to SOCKS on the second (maybe with another SSH connection linking the two). But that’s increasing complexity and cost.
can be defeated with two VPSes, but that’s increasing complexity and cost
A marginal increase, perhaps. You don’t need a separate VPS - just a second IP. Accept incoming traffic on port 22 on one, and set the default route for outbound traffic to the other.
-
This is actually pretty interesting, thanks for sharing. Although i live in a third world country that doesnt care about anything at all including piracy, but this tunneling thing looks pretty handy
Couldn’t you also just set the VPN to use port 443?
E: Apparently this isn’t enough. IE, for Wireguard, you would need to find a way to obfuscate the handshake.
I’m not 100%, but I think you could set this up for free with an Oracle AlwaysFree tier VM.
(Boo Oracle, yes I know. Still very handy.)
Just looked up Oracle Always Free… Good to know about, thanks!

Blocking all encrypted traffic… fantastic suggestion comrade, I’ll forward this on to the Kremlin. Also, you’ve been drafted.
I suppose with “comrade” you are hinting at Soviet customs, but Russia isn’t the USSR and couldn’t be further from being socialist
Settle down, it was a joke
deleted by creator
what
Russia isn’t the USSR but it is heading towards the USSR ways, and it’s already there in many aspects. It’s not just on a technical definition, a lot of pro-war and nationalist rhetoric is rooted in the old USSR culture.
The USSR wasn’t socialist, it was communist. And yes I know, it wasn’t real communism because real communism is a utopia.
Russia isn’t implementing maternal paid leave, a good universal healthcare system, guaranteed housing, food, education, and a job, so it’s not heading for the ‘USSR ways’ and the USSR was socialist
Oh please. In all the ways that matter, it is identical.
It’s a custom protocol that uses SSL/TLS for key exchange and such, so it can be detected. It’s actually causing huge problems for many large Russian companies, as it’s common to use those protocols for remote access, work, etc.
As mentioned in the article you need something like “Shadowsocks” to avoid protocl blocking, since it fully disguises the traffic as standard SSL/TLS. Which was created for, and is still used to circumvent this type of blocking in “the great firewall of china”.
https://security.stackexchange.com/questions/187649/is-it-possible-to-detect-vpn-in-the-network
tl;dr: You can infer that OpenVPN is used from the key exchange somehow.

Unless the whole of the inner IP packet is encrypted,
It is, because they’re inside an encrypted stream of data.
The way OpenVPN works is this:
-
OpenVPN establishes a TLS connection to the OpenVPN server.
-
Your computer’s kernel generates an IP packet.
-
OpenVPN sucks that up, shoves it into the TLS connection. That connection is encrypted, so the network provider cannot see inside it, know whether the data is IP packets or anything else, though I suppose maybe traffic analysis might let one classify a connection as probably being a VPN.
-
The data in that connection is broken up into IP packets, went to the OpenVPN server.
-
The OpenVPN server decrypts the data in the TLS stream, pulls the original IP packets out.
So the original packets are always encrypted when the network sees them. Only the OpenVPN server can see the unencrypted packet you originally sent.
What @raltoid is saying sounds plausible, though I can’t confirm it myself off-the-cuff – that OpenVPN is detected by looking at somehing unique in the initial handshake.
VPN detection is simple: track new encrypted connections outside of Russia, connect to the same server, check if it replies as a VPN server. If it does, block the shit out of it. No need for packet inspection or any voodoo.
Fair enough. I mean, there are ways around that too, like some port knocking scheme, but I assume that this shadowsocks thing solves the same problem in a better way.
But I do stand by what I was responding to on, the bit about the internal IP packets being encrypted and not readable.
-
There’s still headers and it’s fairly trivial to block using packet analysis. Using other protocols such as SSH tunneling may work (until they try to ban that I suppose). There’s always way around these kind of blocks, it’s a cat and mouse game.
Is OpenVPN not just SSL traffic?
It’s not, it’s an IPSec VPN by default which runs over UDP. You can run it via TCP and it operates over the same port as HTTPS (443), but it’s not the same protocol and can be differentiated that way.
A way around this would be to run an SSLVPN with a landing page where you log in instead of using an IPSec VPN or a dedicated SSLVPN client.
Another way around it would be to create a reverse SSH tunnel on a VM/VPC in another country/state and send all your traffic through that.

I think that either I’m misunderstanding what you’re aiming to say, or that this is incorrect.
OpenVPN can run over UDP or TCP, but it’s not IPSec, not even when running over UDP. IPSec is an entirely separate protocol.
Blocking VPN is easy. You detect a new encrypted connection to a host outside of Russia. Then you connect to the same host yourself and check if it’s a VPN server or not. If you get a VPN handshake, you block all access to such host. Boom! No more VPN.

Good read. So it sounds like your analysis of the situation is that it is short sighted and Putin is simply a Megalomaniac attempting to hold onto power, would you say that is an accurate summary? Or is he just crazy and super optimistic that things will change all the sudden one day?
Because even if you kept all the people physically producing bombs and shells, eventually you will run out of the educated people that run the other industries that support the military industrial system in Russia if this goes on for long enough.

I suspect that if things continue in the trajectory that they seem to be heading, that people from Russia who exit may likely be better-off too, as much as moving countries is a significant barrier.

I’d appreciate a source for that statement. :o
Removed by mod
I see! So, to quote the sources you provided:
“Despite widespread speculation, the law does not directly ban the operation of VPNs and anonymisers. However, it does restrict access to banned websites with the help of these tools.”
I.e. the VPN providers themselves are not illegal, though the VPN providers technically have to not allow users to access content listed by rospotrebnadzor. That’s responsibility on the side of the providers, not a ban on use. Practically speaking it still is attempting to censor content, but neither of the three sources claim that VPN use is illegal in Russia.
You can argue as much as you want, but the full usage of a vpn is illegal in russia by law, because you could access real informations instead of their bullshit propaganda.
Yes you can install it freely and “use” it to a certain degree to browse on pages uncle Putin allows you, but you can’t use it completely without any restrictions, e.g the definition of real usage in my opinion. So in my understanding the (full) usage of a vpn is prohibited by law in russia.
And they are now actively blocking protocols…so 🤷♂️
Don’t get me wrong, I think those restrictions are horrible and Putin is a tyrant, but it’s irresponsible to say that VPNs are illegal. They are not. People should use them to access alternative media like Meduza instead of accepting that there’s only state media. VPNs are still incredibly useful and we shouldn’t play into the scare tactics of the Russian government by insinuating that you can end up in jail by using VPNs. I think that’s coming, too, but these tools are still available to get around lots of the censorship. As you yourself noted, most of the VPN providers aren’t actually complying with the law, so you can access way more material, without current legal repercussions to the individual, at least based on the sources you provided.
This is not accurate information. VPN usage is not banned.
Using is not illegal

Illegal to show how bypass bans, it is allowed to use VPNs
But how are their propaganda farms going to be able to pretend they are in your country now?
They still get to operate don’t worry!!
official companies are still able to use vpn 😏
Exemptions that only apply rules to the common people. Maybe device registration with an exception using ipv6 address
Maybe they don’t actually have all those propaganda farms that the dems were crying about, did that thought cross your mind?
Before it was widely reported, Twitter’s geocoding feature showed a ton of Russian-based accounts posing as “Americans” and only discussing politics. Would love to see lemmy be more transparent about accounts posting here too, tbh.
In all honesty, I would expect at least an organized troll farm to use VPNs ending outside Russia.
Random people in Russia might just act directly, but it’s a red flag that’s easy to pretty-inexpensively eliminate.
googles
It sounds like at least the Internet Research Agency troll farm used VPNs.
https://www.bbc.com/news/technology-43093390
According to court documents, the IRA took several measures to hide its tracks, duping the technology companies who were unaware, or unable, to stop what was filtering through their systems.
The key - and obvious - move was to hide the fact that these posts were coming from Russia. For that, the IRA is said to have used several Virtual Private Networks - VPNs - to route their operations through computers in the US. The operatives allegedly used stolen identities to set up PayPal accounts using real American names.
Even if it’s just a hash of an ip4, that would go a long way towards identifying who is coming from where
I’d say you probably want to check my geolocation?
They exist. Inform yourself on the Internet Research Agency, one of Russia’s state sponsored troll farms. A handful of their activities are well documented in factual records. ‘Dems’ weren’t crying about it, every rational person who doesn’t want foreign interference and disinformation flooding our spaces is concerned about it. This should not be a partisan issue whatsoever.
Yeah, I don’t even really have a problem with RT, as long as it’s labeled so that people understand that it’s the Russian state speaking. But a lot of forums rely more-or-less on the idea that people are more-or-less good faith actors. Very large scale efforts to have people pretend to be someone else and make non-good-faith arguments is something that I think that a lot of our forums can’t today handle well.
Arguably, that’s a technical problem that needs to be fixed in some way.
Maybe, but get fucking real.
Sadly, but we have. There is a big propaganda campaign have been raised for the last 2 years. It was here before but not in a such huge amount.

I live in Russia and I have vps with wireguard vpn in Netherlands. At the current moment it works for me pretty well except the some connection failures two days ago. But they were very short. But I don’t know how long my vps will be accessible with these fucking blocking.
You might want to sign up with astrill. Greetings from China, we’ve been dealing with this shit for decades.
Thanks for advice. I didn’t hear about it before. It will be my backup plan.
Can you confirm that it is still working fine on normal home internet but not on cellular data? Have been back to Russia multiple times per year (family reasons) and none vpn ever works on cellular network. Some work at home and places.
My own vpn is to my house in different country. Wireguard. That has always been working over home wifi here (not cellular). Even until now.
For now it works both via mobile data and home provider. My mobile operator is Tinkoff. The home Internet provider - City Telekom. But sometimes it losses connection for several minutes. But generally it works well.
It will be blocked soon. Go read here what to do https://habr.com/ru/articles/731608/
Now comes the Great Russian Firewall.
The Copper Curtain?
I don’t think they can afford copper at the moment. Try cotton maybe.
It was not working 2 day on mobile operators, now waiting full shutdown
yup. kinda same experience. tele2. complete shutdown on my vpn.
Shadowsocks worked fine
Shadowsocks is very difficult to block. What provider do you use for shadowsocks?
I am pretty confused by the article.
What I’d expected based on what I’ve seen so far was that the Kremlin would not care what protocols are used, just whether the a given VPN provider was in Russia and whether it provided the government with access to monitor traffic in the VPN.
So, use whatever VPN protocol you want to talk to a VPN provider where we can monitor or block traffic by seeing inside the VPN. You don’t get to talk to any VPN providers for which we can’t do that, like ones outside Russia, and the Russian government will do what it can to detect and block such protocols when they pass somewhere outside of Russia.
But that doesn’t seem to fit with what the article says is happening.
The media in Russia reports that the reason behind this is that the country isn’t banning specific VPNs. Instead, it’s putting restrictions on the protocols these services use.
According to appleinsider.ru, the two protocols that are subject to the restrictions are:
- OpenVPN
- WireGuard
A Russian VPN provider, Terona VPN, confirmed the recent restrictions and said its users are reporting difficulties using the service. It’s now preparing to switch to new protocols that are more resistant to blocking.
I don’t see what blocking those protocols internal to Russia buys the Kremlin – if Terona conformed to Russian rules on state access to the VPN, I don’t see how the Kremlin benefits from blocking them.
And I don’t see why Russia would want to permit through other protocols, though maybe there are just the only protocols that they’ve gotten around to blocking.
EDIT: Okay, maybe Terona doesn’t conform to state rules or something and there is whitelisting of VPN providers in Russia actually happening. Looking at their VK page, it looks like Terona’s top selling point is “VPN access to free internet” and they have a bunch of country flags of countries outside of Russia. So maybe Russia is blocking VPN connectivity at the point that it exits Russia, and it’s affecting Terona users who are trying to use a VPN to access the Internet outside Russia, which would be in line with what I would have expected.
Your edit makes sense, it would be possible to block all VPN traffic but just whitelist traffic from trusted IP addresses (like those in Russia). But I don’t think we have enough info to say for sure that’s what’s happening.
ProtonVPN has a “stealth” protocol. Does anyone know if that breaks through?
protonvpn hasn’t worked here at all for a long time now lol
It doesn’t work in China, if that’s any indication.
Absolutely doesn’t. Even tried to go like 100 servers to see.
But nothing related to proton get through

Russia is a terrorist state. #SlavaUkraini #ArmUkraineForVictory
I love all my fellow Russians and Ukrainians who rise above the brainwashing that this commenter is demonstrating.
Fuck patriotism and slogans, that’s what politicians want you to do to die for them. All wars would be over in a day if people just realized this as politicians can’t fight their wars without people like this commenter.
Ukraine was invaded bro. Their politicians did exactly nothing to encourage war.
Maybe theirs didn’t, some other countries’ did (and still do) because it advances their interest.
Russia is less terrorist than Azerbaijan, but the latter isn’t even being sanctioned (and there’s been an ICJ decision against them, but everybody ignores it) for starving out a little country of 120k people right now in a medieval siege, and openly stating that they are doing exactly that.
I don’t think Ukraine has lots of problems. At least the aggressor there is recognized for what it is and the victim is recognized for what it is and armed by half the world.
I don’t think Ukraine deserves any attention, in fact, since in Artsakh they support Azerbaijan. Support of now finally actual genocide happening is what makes me think that.
Russian likes to threaten the world with nukes - nuclear war would inevitably lead to a nuclear holocaust that would cause the near extinction of the human species.
I don’t give a flying fuck about Azerbaijan. Russia is terrorizing the entire species of humanity. Until you’re threatening to wipe out the entire planet, you are not a terrorist on the same level as Russia.
Russian likes to threaten the world with nukes
Tactical nukes usually.
nuclear war would inevitably lead to a nuclear holocaust that would cause the near extinction of the human species.
If you use tactical nukes, then it’s not much more significant than using thermobaric ordnance or cassettes or even chemical weapons or anything else kinda nasty and non-conventional.
It won’t lead to a global thermonuclear war and thus a nuclear holocaust any more than use of sarin in Syria did.
However! If you don’t give a flying fuck about a smaller holocaust then I don’t give one about your bigger one even if it involves me, I just don’t care.
If you don’t give a flying fuck about a smaller holocaust then I don’t give one about your bigger one even if it involves me, I just don’t care.
Sure, Russia threatens the entire human species, but if it doesn’t suit your liberal virtue-signalling for some marginalized minority, then it’s fine with you.
What’s the survival of humanity vs your imaginary liberal internet points.
Sure, Russia threatens the entire human species,
Your life is worth at best as much as any Artsakhi farmer’s life. In fact much less, if by “the entire human species” you mean yourself.
Now, Russia can’t threaten anybody, I’d be surprised if any of those strategic nukes are still operational. I happen to live in Russia and know how things are usually done here. That aside, Russia’s regime consists of thieves and murderers, not some Hollywood fascist hardliners. They care for their lives very much.
but if it doesn’t suit your liberal virtue-signalling for some marginalized minority
At this point I’d actually prefer that somebody nukes the miserable being you are.
And people of Artsakh are very much the majority in their land, however they are besieged and dying from hunger.
But, well, it’s good to know that you care about Ukraine only because of being afraid that, again, somebody nukes you.
Also my ancestors on paternal side happen to be from a certain valley in the province of Tayq, Western Armenia, currently occupied by a certain genocidal NATO country. I won’t buy your bullshit. I’ll care about Ukraine and somebody, again, nuking you personally when enough people care about that, which is never.
The people of Artsakh are also people of the world. Russia is threatening them with extinction too. You don’t actual care about them. You’re a fake and a liar begging for liberal minority points online.
Russia is threatening them in much more material way, with all its deals with Azerbaijan (which would be something sanction-worthy for the latter if it were, I don’t know, Georgia), but it isn’t killing them right now.
You don’t actual care about them.
I very definitely do, my aunt’s husband is from there and a participant of the first war.
You’re a fake and a liar
Judging by your use of the words “liberal” and “minority”, I’d say your opinion on the matter is not worth much, neither are you as a whole.
It won’t lead to a global thermonuclear war and thus a nuclear holocaust any more than use of sarin in Syria did.
You didn’t mention the escalation policy of either of those countries during a war event.
Escalation policies tend to become very elastic when implemented by humans.
They really can get to some limited strategic exchange, but after that point some countries are democratic and that demos which supposedly rules them will tear into pieces everybody preventing the cessation of hostilities, and others are authoritarian, and their authority cares about its lives and well-being the most.
I mean, NATO officials have become much more modest with words about “any attack on NATO territory is an attack on NATO” after a few stray missiles have landed on Polish territory, for example.
Escalation policies tend to become very elastic when implemented by humans.
I’m talking about the Rules of Engagement during wartime. Especially when it comes to the release of nuclear weapons. These rules are very un-elastic.
Each use of nuclear force is responded to by an escalated nuclear force reply. This can keep happening until all the missiles are in the air, flying to their destinations.
I think Ukraine is a western puppet. But that doesn’t mean Russia isn’t also shit.
People can wrap their heads around two mean bullies fighting in a schoolyard. But someone when it’s politics many people want a single bad guy.
Ukraine is not “western” puppet, it’s just a big oligarch-dominated part of the ex-USSR.
Say, Transcaucasia was toxic nationalist-bandit-oligarch dominated, with these components being initially almost equally mixed, and to some extent still is.
Russia was oligarch and FSB dominated, until those merged with FSB being on top.
Ukraine was similar, but oligarchs are on top now.
I wholeheartedly agree that Ukraine is better than Russia. It’s just more similar to Russia in the dimension of evil than most here seem to think.
Shadowsocks/ShadowsocksR/vmess/vless/trojan:
Is it possible to bypass this block? Say, embedding VPN packets within a different protocol?
I don’t know why some moron downvoted you, but the answer is maybe. For reference, I have always bypassed SSH firewall blocking by sneaking SSH packets within https.
The only way this won’t be possible is if the government enforces installing a certificate to use the internet, so that they can do a man-in-the-middle-attack. I heard this is already being done in Afghanistan.
So sad. More and more we are seeing a world were the powers that be can do anything they want but if you do it it’s (rightfully) malware and illegal.
The vast majority of popular apps and OSes are spyware by any reasonable definition of the term.
I remember, back in the late 1990s, if I have the time right, when RealPlayer phoned home to check for updates, and there was enormous uproar over the privacy implications.
Things sure have changed since then.
For simple web browsing or streaming over https you can use a socks proxy.
For full VPN function you could try something like IPSec or L2TP, as they’re not listed in the protocols Russia is targeting.
Can someone explain from a technical standpoint how they can block OpenVPN running on port 443? my admittedly limited understanding is that port 443 is the common port for https. If they blocked that port wouldn’t that mean that they would be blocking nearly the entire internet?
You can analyze the traffic, detect common patterns and also detect source of the request. Russian IT specialists are now using very complex solutions to come around the block which work a lot like MITM attacks.
