I am a qBittorrent user. To keep alive some torrents, I always keeps my qBittorrent online. Recently, I found my upload stream reaches much higher than usual. Then I found some peers using github.com/anacrolix/torrent, and they request several torrents continously, brings upload stream hundreds times than torrents' itself. In my opinion, this should be a bug on github.com/anacrolix/torrent, which leads to infinity request to peers. Wish you can found it.

For example: magnet:?xt=urn:btih:e7268b2b2a4c6457ba0c4e40f35b206a08b5cc39&dn=%5BNekomoe%20kissaten%5D%5BAyakashi%20Triangle%5D%5B06%5D%5B1080p%5D%5BCHS%5D.mp4&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80%2Fannounce In this torrent, some IP always request this.

--- Chinese Version, I am sorry that some words is beyond me. ---- 我使用qBittorrent并长期保种。 最近我发现qBittorrent的上传流量明显高于平时，并且我发现有些使用github.com/anacrolix/torrent的用户在持续请求个别种子，产生了几百倍于其大小的上传流量。 我想github.com/anacrolix/torrent一定有BUG，使得用户持续对其它用户发起请求。 希望能尽快解决这个问题。

Noticed some reddit posts about it, just wanted to post here for reference. I personally have also noticed this types of peer leeching from me infinitely, and the transferred data far exceeded the size of the torrent. Apparently it appears on many Anime torrents, both Chinese subs and from English sites. I know it might not be a problem with this library but rather some downstream user, but still wanted to report here as I'm not sure what kind of users are using this client.

Only a guess: It could be some type of shared IP/seedbox/debrid/cloud storage service, (for example 115 NetDisk or PikPak) using Go in the backend, and somehow misconfigured the client so it leeches forever but does not actually save any data or make any progress.

If it helps, the IP leeching from me is from 1.180.0.0/14

Chinese Explaination for OP：看起来有不少人遇到这个问题，我截个图汇报一下，不一定是这个客户端问题，猜测是某个离线下载服务部署出了问题，等更多人来汇报的话看看能不能解决吧

[anacrolix]

Thanks for the report. A few years ago there was a bug that could result in downloading continuously. I think your guesses about broken seedboxes or bad downstream clients are accurate. I'll check into specific details when I get time, cheers.

[slowlearnerLspeedup]

I already baned these names called anacrolix bt clients. What waste of time. They just downloaded some files that sized only 2 or 3 GB, but I had to upload hundreds of times more than the original!!! This is crazy. Unbelievable!

[festoney8]

The same here. It consumed hundreds GB of my qbittorrent upload traffic. I found that peer from ip route 1.180.0.0/14 and 36.102.0.0/16, that means possibly there is a distribution of torrent software with bug, or something more harmful.

[serfreeman1337]

I've taken a look at its traffic, and it seems like it requests already requested pieces.

Please do not ban entire clients (at least include a version in case it's related to a bug). It's heavy handed, and easy to spoof. It's easy for users and developers to react by not revealing their true client names and versions and the situation is worse for everyone. Ban IP addresses that have bad actors, and if you do ban a client, be sure to include the full client string.

[anacrolix]

Just to clarify, the bug I mentioned I believe was when the user ran out of disk space, it would retry indefinitely in a loop. It reports an error message but if the user has spun up a client and is not paying attention it could cause this. It was fixed a long time ago if it is indeed that issue.

The client name that people are reporting is concerning. It doesn't appear to be a downstream client, they seem to be running the provided demo utility. The code that derives this is https://github.com/anacrolix/torrent/blob/7308c68d87af7e46aabe66540202d2171443e700/version/version.go#L42. I welcome anyone else's insight here.

I will unblock them as soon as this bug gets fixed.

[anacrolix]

For example: magnet:?xt=urn:btih:e7268b2b2a4c6457ba0c4e40f35b206a08b5cc39&dn=%5BNekomoe%20kissaten%5D%5BAyakashi%20Triangle%5D%5B06%5D%5B1080p%5D%5BCHS%5D.mp4&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80%2Fannounce In this torrent, some IP always request this.

I didn't have any luck with this link. I did see a lot of peers in China but most of them disappeared quickly. Nobody wanted to download (qBitTorrent or anacrolix/torrent). I wonder if the peers in question are targeting users in specific regions.

[Seele-xier]

I've also encountered a similar issue. I use qBitTorrent, and it detected a client called anacrolix/torrent that kept downloading continuously, even completing over 400 downloads of the same file in one night.

我也遇到了类似的问题，我使用qBitTorrent，检测到有个名叫anacrolix/torrent的客户端一直在下载，甚至一晚上对同一个文件完整地下载了400多次。

I plan to use this regular expression and block the relevant client if it matches. I applied an aggressive version matching because I wasn't quite sure what the next version would be. If possible, I would like to know the specific highest version, this helps to precisely reduce the impact on users. Hope this issue will be fixed soon ;)

Regex: "anacrolix/torrent v?([0-1].([0-9]|[0-3][0-9]).[0-9]?[0-9]?|unknown)" Block version range: anacrolix/torrent unknown, anacrolix/torrent 1.0 to anacrolix/torrent 1.39.99 My search suggested it might be this commit: https://github.com/anacrolix/torrent/commit/8025d1515503f485e4d5e1faa111577748ca49a6

[tuxayo]

Bad news for anyone wanting to ban a specific version, I got a case of a client using the devel one.

And a previous comment also show this version: https://github.com/anacrolix/torrent/issues/889#issuecomment-1883658739

bugged peer ip is 1.180.25.97 my client is qbittorrent

[anacrolix]

@tuxayo I think it's fine to ban that exact string on your own torrent client installation (github.com/anacrolix/torrent (devel) (anacrolix/torrent unknown)). For the most part people developing on anacrolix/torrent won't be bothered (unless it's banned by default for other common clients which I test against). That string should also only matches the demo client, which again, shouldn't bother many users. It's still preferable to ban the IP range people are reporting from China however.

[festoney8]

The same here. It consumed hundreds GB of my qbittorrent upload traffic. I found that peer from ip route 1.180.0.0/14 and 36.102.0.0/16, that means possibly there is a distribution of torrent software with bug, or something more harmful.

Just ban single IP doesn't work, I recognized several different IP from 1.180.24.0/24. So I banned IP range 1.180.24.0/24, 1.180.25.0/24, 36.102.218.0/24 in my client, it works pretty well these days.

[RaySibay]

I encountered the same problem yesterday. It's crazy, when I found the problem, this bad client had downloaded more than 300GB data. Recently, some Chinese ISP is using the ratio of upload flow to download traffic to detect PCDN, maybe it is related to this matter.

Here are some IPs I encountered: 1.180.24.2 1.180.24.220 1.180.24.225 1.180.25.84 1.180.25.131 1.180.25.210 1.180.25.216 36.102.218.131 36.102.218.132 36.102.218.222 221.203.6.54 221.203.6.58 221.203.6.60 240e:918:8008:3::61 240e:918:8008:4::224 It is easy to see the IPv4 IPs are in 1.180.24.0/23, 36.102.218.0/24 and 221.203.6.0/24, I am still observing IPv6 IPs range, may be 240e:918:8008::0/48. Mostly they request 2.3MB/s from my computer. Moveover, how to write a rule to ban IPv6 range?

Create a TXT file, write these lines, and rename it to ipfilter.dat, then choose it in qb

1.180.25.0-1.180.25.255
36.102.218.0-36.102.218.255

[anacrolix]

I've added a likely fix (bdcb6c9fcdebbc5ac8825c11f3177464d95efee1, on master) for errors during download that might be the cause of this problem for the bad peers people are seeing. It will be included in v1.53.3 and above.

Due to https://github.com/golang/go/issues/50603, users running the cmd/torrent utility from source will always show github.com/anacrolix/torrent (devel) (anacrolix/torrent unknown) for their extended handshake client version. Is it possible to discriminate against clients based on their peer IDs instead? In this case I can bump -GT0003- for big protocol fixes like this.

If anyone is testing anacrolix/torrent for this issue, please try with the fix above. Unfortunately existing clones of anacrolix/torrent out there will need to be updated to include the fix, if you operate one of those, please give it a try.

这些 IP 段到底是偶然还是必然是一个不可知问题. 至少, 就上面看到的 IP 段中, 有内蒙古的但也有辽宁的 IP 地址, 且来自不同运营商, 屏蔽客户端很方便, 但也不完全合理, 从汇报数据判断并解决也许不错. 就我而言, 我不太愿意相信屏蔽 IP 段是一个可持续的做法, 可以说这只能是一个临时做法, 因为你无法保证这种客户端不会越来越多.
由于此问题, 最近有一些 qBittorrent 客户端屏蔽器已经更新来应对此问题. 不过除此之外, 你还可以使用 qBittorrent-Enhanced-Edition 解决此问题, 这是一个 qBittorrent 的分支版本, 其自带客户端屏蔽功能. 对了, 补充一下, 标题的 qBittorrent users 显然是有问题的, 因为不只是 qBittorrent 用户才看得到.

Whether these IP segments are accidental or inevitable is an unknowable question. At least, as far as the IP segments seen above come from different regions (for the time being, China) and from different ISPs, blocking clients is very convenient, but it is not entirely reasonable. A better solution is to look for unreasonable data issues from the client data itself and automatically determine and resolve them.

As far as I'm concerned, I'm not willing to believe that blocking IP segments is a sustainable approach. It can be said that this can only be a temporary approach, because you can't guarantee that there won't be more and more such clients.

As this issue arises, some qbittorrent client blockers have recently been updated to address this issue either by name or mechanism. Alternatively, you can also try qBittorrent-Enhanced-Edition, which is a forked version of qbittorrent.

要是有心人可以通过ip预留的电话去滥用报告试试，应该能查出来是谁在乱搞

The contact information from Whois usually points to ISP or something like that. So I won't expect contacting them will do any help.

While I believe this can just cases where people left some unattended downloader that happens to encounter the bug mentioned here. (Believe me, it is not until I came across this issue that I noticed those leechers are taking ~40MB/s bandwidth from me)

By any chance, does anyone know how to find which seedbox provider (or something like that) operates the clients at 1.180.24.0/24 & co? To tell them to upgrade, who knows what is their update schedule.

Those ip addresses are supposed to be located in Mainland China, where not many seed box services are available.

Well, if this is just due to the bug just got fixed here, appearence of new such leechers won't be a concern. Those misbehaving client should restore as they are rolling to newer release of this library.

While if this is some kind of deliberate attack to the bittorrent network, banning ip range would be the best approach until bittorrent software authors implement a way to address such malicious behavior. Since it is very easy to spoof things like client id, if you have the intension.

你这么一说，我就觉得应该是某些人因为宽带上传流量太大被运营商怀疑PCDN后清退，怀恨在心蓄意制造有BUG的客户端，想拉其他正常用户下水，让运营商乱封号

@Moredistant it may be a genuine bug. I do know that anacrolix/torrent is popular in China, but I don't know why a ton of servers there would be running the demo client, that's odd.

Per https://github.com/anacrolix/torrent/issues/889#issuecomment-1891242553, please upgrade to master if you are using anacrolix/torrent, by using go get github.com/anacrolix/torrent@master, or pulling master in your git repo. Let me know if the issue is resolved.

If you are a BitTorrent user affected by this issue, please do one or more of these things, in descending order of preference:

1. Block the client version string github.com/anacrolix/torrent (devel) (anacrolix/torrent unknown).
2. Ban the IP subnets mentioned above.
3. As a last resort if you can't do 1.: Block the -GT0003- peer ID. Do not do this permanently for a client implementation as it will block a lot of existing legitimate users. I will upgrade the peer ID when I have confirmed this fix or release the next version of anacrolix/torrent.

I have created a discussion to track further information so this issue can focus on the fixes to anacrolix/torrent.

The issue relating to infinite requests on storage write errors is resolved. The ongoing leeching issue by bad peers is in the discussion. If anacrolix/torrent adds defenses against that behaviour (assuming it doesn't already) it will be a separate issue.

说来很奇怪，我用群晖nas套件版transmission下载种子的时候一直有速度3M/s以上，但是本地文件保存不了，下了两天完成度都是0，但是流量一直是有的，换了几个种子都是这，干脆换qb了。

你应该是没有把transmission的用户组加到你共享目录的权限上，如果你不太明白可以用docker版的tr

一开始我也是这样想的，但是在群晖共享文件夹的权限设置里的内部账户里没有找到tr的账户，之前使用都是正常的，也不知道动了哪里导致这这样的-------- 原始邮件 --------发件人： jd04063221 @.>日期： 2024年3月22日周五 21:15收件人： anacrolix/torrent @.>抄送： astangcong @.>, Comment @.>主 题： Re: [anacrolix/torrent] Client requests indefinitely on storage write errors (Issue #889)
