No peers connecting


#21

@ichorid Considering that anonymity is Tribler’s unique selling point, I would say, DHT checks should be anonymous by default (and obfuscated if possible).

If a potential user prefers un-anonymous downloading and/or DHT checking, there are plenty of alternatives to choose from, so no need to cater towards those people.

I wouldn’t expect these DHT checks to be very demanding on the Tribler’s exit nodes, but would it otherwise be an option to relay them through the TOR network?


#22

@LesVerres, anonymous DHT checks are more complex to implement efficiently. We got a ticket for this problem since 2017.


#23

I agree with you. I started using Tribler a couple of years ago because it allowed to download anonymously. Telling us now that we have to disable anonymous download to make it work is like if Tor’s developers would ask us to disable all its features if we want to keep on using it… For that purpose we already have Firefox. If this issue is not solved I’m afraid most of Tribler’s users (including myself) will start migrating to other clients.


#24

@heribator, Tribler is many things to many people. Most people use Tribler to download things non-anonymously and only use anonymity functions from time to time. The problem is how to present both anonymous and non-anonymous download options in the GUI without compromising security and usability.


#25

@ichorid, the first you see when you enter Tribler’s website is:

“Privacy using our Tor-inspired onion routing
Search and download torrents with less worries or censorship”

I don’t know about other users, but as @LesVerres said, for me this is the main factor that makes Tribler better than other clients. Without it I would have to reconsider my choice and see if it’s still above the rest.


#26

@ichorid I’m curious, how was it established that most people use Tribler to download things non-anonymously?

Furthermore, from the expression of this behaviour, the user’s preference to do so can’t simply be inferred (to be clear, I’m not saying that you did).

Although anecdotal, the main complaint of other Tribler “converts”, I received, was the low download speed (although it must be said, it has improved considerably). This lead to situations where users gave up anonymity in favour of download speed, even though they rather would’ve had both. This could have contributed to the behaviour you described.

I’ve read the ticket of the DHT check problem and I see the complication.

That being said, I think @heribator provided an applicable analogy, taking into account the way Tribler promotes itself.


#27

@LesVerres, @heribator you make a valid point about users mainly coming to Tribler for anonymous downloads. However, they soon discover that our technology is far from perfect and anonymity reduces performance. Then they start to differentiate their anonymity usage.

Again, this is anecdotal. We can’t check it because we can’t track our users. However, running Tribler exit nodes gives us some insight into our users’ average behaviour. Last year we doubled our exit nodes’ bandwidth capacity, and yet this capacity is not completely utilized to this day. For me, this indicates that the default behaviour for our established userbase is to only use anonymity when it really matters. Probably for reasons described by @LesVerres

After all, presenting an option for non-anonymous download is a workaround for imperfect anonymity technology.


#28

I must say it’s rather disappoiting the way @ichorid reacted recently. Tribler is troubled by an exit node problem, ichorid said some three days ago. Fair he did: in a complex setting problems can arouse and even persist a while, Overt pointing out the course of the problem can be effective in finding a solution. But it’s no use changing the course of the debat to wether or not users want anonymity. There are far better, a least faster, clients if your only object is to connect to seeds and peers. That needs no discussion. So back to the problem. If it was persisting after 1 or 2 days we were asked to report that. I can confirm the problem persists.


#29

The ink of my message still being wet I see that the problem changed. Earlier this morning it fully persisted but now there’s a change: from a complete absence of seeds/peer connections I now notice a connection, not always stable but nevertheless… I will keep track of it.


#30

It’s been three days so I just want to report that I’m still experiencing the problem. Had been for a day or two before your post, and it’s still persisting exactly the same as it was. Slightly different to what a couple others have said, my client shows both 0(0) seeds and 0(0) peers as well for all torrents with one or more hops (and instantly shoots up to higher values and starts downloading as soon as I turn anonymity off, like others have reported).
Any word on a resolution to this issue?
I’m still using 7.3.2 by the way, as any later client I’ve downloaded (7.4.0, 7.4.4, and 7.5.0) crashes on startup for me (Windows 10), but that’s a separate issue…


#31

I’m sorry to say, but the problem is back. No seeds no peers connected (other than only for a while).


#32

@ichorid It’s three day later, unfortunately I can’t say I see any improvements.

Last year we doubled our exit nodes’ bandwidth capacity, and yet this capacity is not completely utilized to this day. For me, this indicates that the default behaviour for our established user base is to only use anonymity when it really matters.

That seems a very bold conclusion based on this single metric. Is the exit nodes’ consumed bandwidth indicative of the actual demand of Tribler’s users (e.g. considering bugs like this one), what other factors could influence this outcome?

Furthermore, what does it tell about the absolute demand for downloads of your user base? What does it say about their considerations on whether or not to download anonymously?

If there was an overcapacity in bandwidth, was it redistributed over the current users? How did this overcapacity vary over time? Was it an average overcapacity or was it persistent? It would be interesting to see it plotted out over time.


#33

Interesting questions @LesVerres but the main thing stays: Tribler differs from other torrent handlers and what the difference is one can easily see opening Triblers website. That leaves no doubt about Triblers identity. So the discussion about whether or not there are users that use Tribler for other reasons is distracting. You can’t say: here we have the perfect faciltity for you to become a high jumper but we don’t have bars.


#34

Absolutely, there should be no discussion about that. In my opinion, the development aim should be to overcome the shortcomings in the program, not to facilitate users to make compromises.

Bypassing anonymity would be acceptable as a fallback measure only.


#35

Greeting to all.
I have been experiencing this problem of zero seeds and peers (with a few dribbles now and then) since at least 2nd May.
ichorid wrote 3 days ago ‘… should be resolved in 1-2 days. Please, report if the problem persists after that.’
I can confirm that the problem still persists.
Thank you for your help.


#36

Issue still seems to persist. Client tries to connect to peers/seeds it finds, but fails most of the time. Had one file able to connect to one peer and get up to 1.5MB/s, but lost connection after just a few minutes.

Speed is there, just seems to be unreliable to connect to peers.
This thread points out a good question, if Triblers main selling point is no longer “privacy”, what is it? There are far better clients for non-anonymous transfers. If I can get up to 2MB/s, then the exit nodes does have capacity, but is it due to this issue, or that users aren’t using the anonymous feature?


#37

A few hours after my last post and things seem to be working again! My torrents are downloading and finding their seeds and peers again. Hopefully it’s working for everyone else and this means the problem’s been fixed :+1:


#38

I too can confirm that things seem to be working fine.
Thank you for fixing it.


#40

I see some down and upload activity appearing, though not a lot.


#42

Another dev here. It’s unfortunate to hear about these problems and we will try to address them as soon as we are able to. There could be problems with anonymous downloads outside our control (e.g., a lack of exit nodes or a congestion of them). Direct (non-anonymous) downloads should always work since they are not proxied through other Tribler instances.

To quickly detect these kind of bugs, or to even prevent them from happening in the first place, we have invested time in an application tester that tests the aspects of Tribler that users are most likely to use. You can find the source code here. However, to get the quality of this tool up to a level where it can reliably run on all supported platforms, and for extended periods of time, takes effort.
