I think what we’re seeing here isnt Valve messing up but rather the middle east conflict expanded to cyberspace and spilling over to impact civilians. Look at the timing and affected countries. China isnt also exactly known for free internet.

WebRTC works as fallback. WebRTC is encrypted and cant be used for much else.

STUN in the otherhand is unencrypted and the protocol itself can be used for DDoS reflection/amplification. I would not be surprised if this is somehow weaponized and/or blocked/analyzed in real time that then breaks the connectivity.

numpad0•3 days ago

STUN/TURN is basically icanhazip for WebRTC. STUN gives you your public IP:port. TURN is the same, but the returned IP:port is the one that had been dynamically allocated to you at time of querying, rather than the actual ones.

WebRTC clients take that STUN/TURN response and send to peers through out-of-band, through e.g. a lobby server chat mechanism, to set up the connection. This allows NAT table entries to be created as if they are outbound connection at both ends.

You can't make P2P connection with STUN/TURN alone. STUN/TURN is just a tool required for WebRTC.

bob1029•3 days ago

TURN is the last resort and isn't just signaling. It carries the traffic as well.

If you can make all the STUN servers fail from the perspective of the clients, you could hypothetically force them to use TURN servers that are more centralized and easier to spy on. STUN negotiates pipes n:n. TURN is closer to n:1.

michaelt•3 days ago

> force them to use TURN servers that are more centralized and easier to spy on

Webrtc traffic is encrypted as it travels through the TURN servers, isn't it? Sure, you get some which-ip-contacted-which-using-what-service metadata, but any active middleman able to mess with STUN traffic already has that.

It could just be that someone's fucked up a setting somewhere. I mean, the reason WebRTC has loads of options for 'interactive connectivity establishment' is because it's common to see users behind NAT, users whose NAT cant be traversed with STUN, IPv6 being broken, UDP getting blocked, TCP ports other than port 443 getting blocked, etc etc.

If a country's ISPs use CGNAT to avoid giving users precious IPv4 addresses, and world events made the ISPs turn the security settings up to 11, STUN just stops working.

> TURN is the same, but the returned IP:port is the one that had been dynamically allocated to you at time of querying, rather than the actual ones.

I don't know you mean by this, but I think you're confused. I have implemented STUN, so I know how it works. AFAIK, TURN doesn't reveal an address/port any different from that revealed by STUN, and cannot, because its discovery feature is STUN. (Also, a typical home user has only one internet-facing address, not a dynamic one plus another one.)

Rather, TURN provides a STUN address/port discovery service and a data relay service. The relay is for cases where two peers wishing to connect are both behind difficult NAT, meaning there is no quick and reliable way for them to directly connect even when they have their STUN results. So instead of connecting directly, they communicate through the relay.

numpad0•1 day ago

I admit that I only have rudimentary understanding, but: my understanding was that TURN uses a modified STUN format that returns the address/port on the peer facing side of the TURN server, a la address of a hotel room or PO box, of querying user. My point is that STUN/TURN(especially STUN) are not encapsulation protocols for WebRTC, but just means to determine(or get assigned, so TURN sort of is encapsulating, by being a transparent proxy) client's own public IP/port because there is no way to do so than by asking someone with a global IP.

ars•3 days ago

I think you have that backwards, WebRTC doesn't work, and STUN does.

RossBencina•3 days ago

I think you have it sideways. STUN [1] is the NAT traversal / "NAT hole punching" process that allows peers to discover their public IP addresses and establish direct P2P bidirectional UDP communication. WebRTC depends on STUN to establish P2P communication. You may be thinking of TURN [2] which amounts to routing traffic through an intermediary node that is visible to the two peers.

api•2 days ago

We do P2P in our networking software and this is why we do it all in band instead of using STUN, TURN, or other common methods. Those get blocked and they’re also often insecure.

STUN has mitigations now against being weaponized but it’s still a shit protocol. The fact that neither STUN nor TURN contain any way whatsoever to accomplish any kind of rendezvous without yet another signaling path boggles my mind given how easy it would have been.

apitman•2 days ago

> The fact that neither STUN nor TURN contain any way whatsoever to accomplish any kind of rendezvous without yet another signaling path boggles my mind

Interesting. Can you expound on this a bit? How does ZeroTier do it?

api•2 days ago

ZeroTier has "roots," which are nodes that relay packets and also tell you what your IP info is. Everyone in the world connects to a pool of these.

Other than relaying and STUN-like IP info reflection, they're dumb and do very little. They can't see your traffic or other information or even what virtual networks you're on.

Once both sides learn their external info, they communicate via the root to arrange P2P rendezvous. If both have IPv6 they use that, but still do a hole punch due to stateful firewalls. But with V6 it works almost 100% of the time. If one or both have V4, they do more cumbersome V4 hole punch maneuvers.

Our next-gen product, which is still in pre-release and has been shown only to some enterprise customers, is called ZeroTier Quantum. It's called that cause it's built on PQC (pqNoise to be exact) but it's also a full-scale reengineering of the whole system. But it still uses very similar techniques. Everything is in-band. No STUN, TURN, or even DNS dependencies.

xlmnxp•1 day ago

I developed WireGuard-like P2P VPN on WebRTC and performance was great 300Mbps+

I think we can align on WebRTC for realtime P2P gaming and enterprise networking and more, instead of IPs base solution as end-users will not need to figure out firewall issues and IPv4/IPv6 differents

I know I'm just preaching to the choir here but my favourite thing about open source/published source libraries/applications is discussions on bug reports/pr's like this.

It's just something so heartwarming of multiple people coming together to describe their symptoms, workarounds and theories of what could be causing it.

GitHub discussions used to be so much higher quality though when the platform was for professionals. Now, I see so many discussions that devolve into practically being reddit/4chan threads. Another reason to leave.

Only on those posted to social media including Hacker News. There is no devolving into memes for niche discussions only interested parties know about.

Don’t blame Github for getting spammed whenever an issue reaches the front page.

Title does not match GitHub issue: "Major P2P issues in Israel and possibly other middle east countries"

RossBencina•3 days ago

Wild hypothesising here on HN but if you read to the end of the GH issue users have been reporting that STUN has been failing (i.e. no P2P link establishment, fallback to high-latency relay servers.) Multiple users have been able to work around the issue by manually substituting older Valve WebRTC dlls. I'd love to read a postmortem from the Valve devs.

komali2•3 days ago

Valve fascinates me because the devs there occasionally seem to be simply the best on earth in a given field, but despite that, bizarre bugs will persist for a long time. My favorite was how steam in home streaming from a PC to a steam deck wouldn't work if the steam deck had an Ethernet and wifi connection - one of the connections had to be disabled or the stream would always crash.

Maybe they need a few average devs there to spend time sweeping up behind the paragons that are pushing the envelope into these features existing at all.

3form•3 days ago

The company is very small, and they're doing a lot with what they have. Steam alone is full of arcane features that I keep discovering. There's a lot of backend stuff. They're making games and hardware.

Perhaps some of this is contracted, similar to the Linux compat and drivers, but it's still impressive to me, compared to the orgs like Spotify, order of magnitude larger with barely any features at all. (I understand there's legal, huge backend, and I didn't see many bugs over time, but still)

trumpdong•3 days ago

The company makes $50,000,000 for every employee each year. It can afford more employees.

zipy124•2 days ago

But would it actually help. More employees means more communication and overhead. Lean organisations can move much quicker. Part of why valve can do what valve does is how lean it runs.

DanielHB•2 days ago

The number of developers needs to grow log(n) to the number of users to handle all error reports. Valve is way under the log(n) of user.

stackghost•3 days ago

Valve famously has a very flat org structure so it's possible that that problem just isn't sexy enough for someone to pick it up on their own, without being told by a higher-up.

I wish they offered remote; I'd happily work there doing those sorts of unglamorous bug fixes. High-reliability engineering is my jam.

sph•3 days ago

People keep blaming the flat org, as if conventionally-organised companies never had any bugs or never focused on very visible and marketable features rather than bug fix.

In fact, the flat org allows a random person to work on a niche bug management doesn’t seem to care about, which wouldn’t be possible if you had a boss breathing down your neck.

They say they have a flat structure. People who have worked there, despite some axe-grinding, indicate otherwise.

mhitza•3 days ago

My favorite bug family, that somehow to sneak in every time, is how their react frontend (or whatever the store runs) manages to semi-crash and the controller inputs are no longer recognized.

I kind of hope at least they'll fix such issues permanently before the steam machine release.

philistine•3 days ago

That is the bane of my existence. Steam's UI is so slow to react due to its web roots, that I feel like people must be insane to think that Steam is somehow this great app. It's terrible.

I shop on GOG.

csande17•3 days ago

Steam was rewritten in React relatively recently. I think most people formed their opinion of Steam back when it was mostly developed in VGUI, the same in-house native UI framework Valve used in games for stuff like the Half-Life 2 title screen and the TF2 server browser.

NekkoDroid•2 days ago

I actually wouldn't blame the web roots. Battle.net is also a CEF based launcher and it feels so much more snappy compared to Steam. For some reason Steam just feels really slow.

Then don't make this thread. One can't discuss an issue about Israel/middle east's internet connection while pretending the war doesn't exist. Technical issues don't float in a perfect vacuum sphere.

babuskov•3 days ago

The rabbit hole started as a major P2P issue in Israel and possibly other middle east countries and further investigations revealed it seems to be a worldwide problem.

tancop•2 days ago

worldwide means israel russia and china so far. all countries that dont exactly like internet freedom and have a long history of spying and censorship. this might be a side effect of some government policy against p2p networks designed to make it harder to bypass censoring isps.

saidnooneever•2 days ago

this looks like not Valve issue. the problems noted seem to indicate only countries which very aggressivly scan and filter connections. P2p is very sensitive to this.

SDR is a relay network, and encrypted, so like onionrouting etc.

its well known malicious actors can abuse it by publishing a p2p game and running coms over SDR via that game...

you can imagine that people want to inspect this traffic in these regions..

ulveclok•1 day ago

This Steam problem has affected all countries worldwide. There are confirmations on twitter from european, japanese, and other residents of "free" countries. The fact that only israelis, chinese and russians are complaining doesnt mean its related to their governments. Its just that in "free" countries Steam servers (SDR) are located throughout the country, while in "non-free" countries these servers may not exist at all. For example, to play with a neighbor both russian players need to connect to Sweden. I hope you know the geography and can predict the ping depending on how far a russian player might be from Sweden.

Is this a bug on Valve? Or is it simply a case of "My ISP is fucking with my internet traffic and they won't admit it please help me"

bigibas123•3 days ago

Reading the github thread points to a case of: "My country's governemt mandated it's ISPs fuck with my internet traffic, but steam P2P stuff used to not be affected but now is" across mutiple countries. People have found it works again if they roll back some of steam's dlls so Valve can probably fix ir.

picofarad•3 days ago

Hm, I have always wanted to use this to play couch co-op remotely but is this even the same "service" that provides that?

Looks like they tracked it to a steam update in March, and there's a workaround for at lest 3 games that involves all players copying steamwebrtc.dll to the game's ./binaries folder.

My unpopular opinion: Valve is basically a parasite or a landlord. They've been so successful it's hard to imagine a world without them, and they say "you gotta give the parasite its due" and we believe them and comply.

It's been kept around because they treat their customers ok, but they absolutely exsanguinate their developers.

And their engineering culture is... odd. They hire senior people and then let them all fuck sound aimlessly. Their APIs are terrible, their infrastructure is all over the place, they still have patch Tuesdays. But because they are the landlord that owns every house in town, what are you going to do, not pay rent?

Gabe is out there cruising the world in a billion dollar yacht, eating thousand dollar meals. All that came off the backs of developers who actually make the games.

This is true, but "treat their customers ok" goes a long way. When everybody else severely abuses their customers, the one company that doesn't generates a lot of goodwill.

faidit•3 days ago

Eh, Steam is kind of like the liberal democratic US empire. It may be evil in a lot of ways but it could actually be a LOT worse. We may actually historically be very lucky to have had a non-shittificationmaxxing games platform for a couple decades, just like we were lowkey lucky that the world was briefly ruled by a somewhat democratic country.. Enjoy both while they last, may not be around long.

gacgacgac•about 10 hours ago

> the liberal democratic US empire. It may be evil in a lot of ways

May be? It's absolutely evil in a lot of ways. It's an active participant in multiple genocides at the moment. And has been for a long time.

I guess it could be worse, but being stuck laboring under Saruman's orcs and pointing at Mordor and going "At least we aren't over there" isn't exactly a defense of the situation.

It’s fascinating how (mostly western liberal) game developers argue in favor of 99% taxes for general population “for maintaining infrastructure” and yet cannot fathom paying a fee for maintaining actual infrastructure that is necessary for their business to function.

simoncion•2 days ago

It makes a lot of sense for businesses to seek to reduce their costs wherever they can. But, from what I've heard about brick and mortar distribution, you used to pay quite a bit more and get a lot less than what Steam gives you.

From what I can tell, that 30% cut gets you -for the rest of forever-

* distribution for both the current version of the game and some number of older versions you choose to make available [0]

* a place in their searchable games index [1]

* "cloud" storage for your players' savegames

* basic forum and blog hosting for discussion of and news about your game

From what I could tell as someone who used to buy games in retail stores, in a bricks and mortar distribution unless you were -like- the Starcraft/Diablo/Warcraft boxed set, you got like maybe a half year of time on the shelf. I've heard folks say that you had to pay a 50->80% cut for that.

[0] Valve will even distribute games that don't work anymore. This is both good and bad, but Steam's no-hassles refund policy combined the existence of unofficial patches that make games work on current versions of Windows make me generally fine with charging for and distributing games that no longer work as-is.

[1] ...at least until the wrong horde of pearl-clutching busybodies demand that credit card companies require your game be erased from the commercial world because it is art that discusses those busybodies' bugbear du jour

The Epic store is horrendously slow though. I bought a few games there but in practice the client is just so slow that I avoid it if I can.

Totally agreed. I'm building a Steam competitor, that's web-based (WebGPU/WASM) as well as cross-platform. Light on games atm, but the goal is to replicate over time virtually every feature Steam has to offer, as well as more. You can check out a preview of the portal here:
