Long story short, P2P seems to be causing issues. In our flat of 17 or so people, we have one flatmate that seems to be torrenting, or at least has an absolutely insane amount of outbound traffic. Like clockwork, whenever he comes back and turns on his computer, many of us disconnect from IRC, games, Skype, etc. Web browsing remains fine, but anything that operates in real-time basically fails.

We finally talked the flatmate into disconnecting their system temporarily to show that it was the issue. Unfortunately, we're still having difficulty connecting to anything. Does anyone know if Slingshot's traffic shaping basically detects P2P usage, and then throttles the entire connection for a set amount of time? 

Thanks!

wasn't this all explained here and given you have now found one using torrents out of 17 users maybe its just too many people

Well he will be hammering the connection so of course it will take everyone else down

What sort of connection are these 17 people all trying to share?

Jeffnz, we've had eighteen to twenty devices connected for the last several hours and everything worked wonderfully throughout the entire day. As soon as this computer came online, it all just kind of collapsed again.

Skewt, it's unfortunately an ADSL connection, haha. Almost all of the flatmates are great about sharing, though, mainly because almost everyone just does really light stuff such as web browsing.

He needs to just stop torrenting and if he wants to, limit it to hours where people are asleep, its called being considerate to others

Yeah, I agree. I've tried to talk to him about it. I think I'm finally getting through to him. I've compiled together quite a bit of evidence against his behaviour, and I've talked with several other flatmates about it as well.

I don't think he "knows" he's torrenting, though. He doesn't seem too tech-literate and appears to just accidentally be seeding content, or doing something entirely unrelated. For all I know, his system may be infected. I saw quite a bit of connections of his opened on ports that looked like NetBus/Whack-A-Mole.

If he's saturating the upstream then everybody's downstream will suffer.

17 people should be able to take on one guy. Tell him to sod off to another flat or to get his own internet connection.

I'm amazed you 1, have 17 people in your flat. 2, manage on ADSL. Try get VDSL at least for that number of people!


sbiddle: I don't quite understand the people protesting against paying a fee.

Why do stores play music? Because it creates ambiance and adds to the shopping experience. Why should the owner of that content not be compensated for that?


wrong thread perhaps?

Good news: We finished the "research" and he reconnected his PC. A few minutes after him doing so, I was able to show him the connections that his computer was opening through the router logs and how I was disconnecting. He didn't believe me at first, so he went to talk to another flatmate that was having the same issue. Their story was the same as mine (just less technical).

I'm going to be investigating his computer on Thursday (when he actually gives me the opportunity) to see what's causing all this traffic. If I can get it sorted out, we should be fine. If not, he said he's frustrated and that he'll be finding a new flat. Either way, it's a win/win, haha.

It's unfortunate how difficult he's been to work with, though. I'm just happy that we'll have a resolution soon enough.

I'm also quite amazed how well we fare on this ADSL connection. We actually are going to be upgrading to VDSL within a couple of weeks, fortunately. The modem should arrive soon (if it hasn't already) and Slingshot will be out for the upgrade shortly thereafter. Like I mentioned, most people either do really casually web browsing, or are extremely courteous. I've helped out several flatmates so far with various network and technical difficulties and overall they've all been quite appreciative. It's just this one guy that's unexpectedly raised hell.

worth considering, if hes hammering with too many connections, it would be hurting the network even more so.

might be easier to sit down and have a conversation about being reasonable, keeping torrents out of peaks, capping speeds, limiting active connections.


in my time sharing connections, i spent a few months in a flat with someone who did the occasional light bit of torrenting (im not gonna proclaim im any angel there, but i prefer to download then ftp home.) i knew the traffic patterns of what it would do to latency, and could tell as soon as they started, its time to go out for a little while, or switch games.

was only a bit of an improvement from sharing a 3/1 rural connection with family (which i went to the extent of speed capping certain devices...)

simply put, i didnt share too well.. i like to have a nice consistent low latency...

I was the torrenting guy once, reduced the number of peer connections and limited both upstream and downstream speeds but still tended to lag my flatmates games. It all started happening after Telecom made a change to the queueing setup on its backhaul network (I asked them). The solution is to avoid torrenting anything while there is any other person using the network. Torrent software generally has settings for what times to run slower and what time to stop the torrents altogether.

i too was it once, and kinda still am (well minus the torrenting at home). im also a gamer however, whos very sensitive to latency - the difference between 30 and say 60ms is noticeable, as is jittering by maybe 1ms vs 10ms.


i can tell from afar, when gaming, if someones downloading heavily, uploading heavily or torrenting simply by the havoc it wrecks on udp streams and latency.


i prefer to stick with an isp with decent routing, and let tcp window scaling do it work. one scaled ftp transfer thread is far more nicer on the network than torrenting the hell out of it - and takes just as long as torrenting anyway with my setup..



cant say i ever looked into an ISPs queuing setups though.

Really?   you can tell a difference of 30ms,  or three one hundredths of a second?

Those are some pretty impressive pro-gamer reflexes you have there.

in saying i can tell, its more, its noticeably not normal. that 30ms can be pretty important though..


im not saying i could sit there and say that is 30ms away and that is 60ms.

Any competent gamer can, 30ms - 300ms is a game changer is most games

If i ever torrent it is usually 10pm+ after we have all really stop the usage




I'm going to noob myself past judgement

yes,  30ms to 300ms the difference is obviously noticable. Nobody said it wasn't. 

But nobody but pro-gamers are going to be noticing real differences between 30ms and 60ms IMHO
