This repository implements BitTorrent-related packages and command-line utilities in Go. Downloading random executables from the internet is not a good idea. How should they know qbittorrent is safe as long as it's downloaded from www. Or at least was for awhile. They already know they can trust firefox and chrome, so it's better for them to just do that.
That's before you get to questions about security of the clients, security of the website you are downloading the torrent clients from, etc. Though their GUI nowadays promotes snaps and I'm not sure how much that is better than random executables. Yes, but a non-tech-savvy person is probably using Windows or Mac My sibling in particular is definitely using windows though they do use WSL for some of their work.
I thought a bit more about app stores and came up with the idea that Microsoft Store should be not that bad, because they probably have money to hire a lot of moderators. But search for "torrent" on microsoft. More so than a torrent client. Google is a known evil.. Browsers are far more battle-tested than just about any other web-facing application on your computer.
Of course, you could make the personal decision to trust a client, and that is fine. They also have a monstrous attack surface because they are "web-facing". A specialized client that only implements one protocol without any connection to the "web" is far easier to reason about and debug. If you only consider the number of man-years an application has been battle-tested, you imply that design complexity and attack surface doesn't matter.
But a bittorrent client isn't trying to be a browser and all the complex stuff that requires. All it's doing is downloading bittorrent files and having a usable GUI. And as the original article demonstrated the first half of that is a weekend project. A "miner" wastes a bit of my cpu while I have the website open, frankly, who gives a crap? If I do give a crap I'll notice and close the webpage. I'm much more concerned about "real" viruses like ransomware that the browser does successfully protect against.
Lots of people give a crap, myself included. Why would I run a resource hungry browser process with a huge attack surface and support for dozens of protocols, plugins, etc for the entire length of the transfer just to download some files? I trust my own judgement much more than some random webpage. Moving the application layer to the browser won't magically solve trust and security problems in the long run.
This is a battle OS vendors should resume fighting. From a user's perspective it "solves it" because you already have to trust the browsers security. Or in other words torrenting becomes no worse than everything else you do. Busy box I think has a torrent client in it and most Linux distributions ship with that if I remember correctly. The internet tells me busybox doesn't provide a torrent client.
But you're missing the point, even if it did it wouldn't be a torrent client non-technical users can use. It's not me , a programmer, who I'm talking about here. JustSomeNobody on Jan 5, root parent prev next [—]. A decade ago now, I wrote a bit torrent client  that started as a project for a software development class. I think the focus of the class was roadmaps and other parts of the development process for a larger project.
Most of the groups picked games or things like that. We chose to build a bit torrent client and I ended up continuing working on it for a year or so. I was pretty proud of it at the time. I'm sure there are a bunch of implementation details that seemed like a great idea as a Sophomore in college that no longer sound so clever, but the implementation is pretty sound.
I used it to download a lot of stuff over the years. The part I think is most interesting is the code for managing the torrent pieces and writing them into the proper places for the various files within the torrent. Not necessarily my implementation of it, just the math behind the process  I remember feeling really clever the first time everything came together and actually downloaded a full torrent.
My first bit software development victory. That's great to hear I know there are quite a few developers who would do lots of different projects, but only to the point of getting something that barely works, and then never use it again. Having it in regular use means you have to continue to fix bugs and make improvements, which a lot of developers unfortunately seem to hate doing, although it's often the more valuable skill.
Not necessarily my implementation of it, just the math behind the process Can you explain a little bit how this is interesting mathematically? On first thought, it seems like you would probably use a lot of pwrite, or if want convenience over safety, mmap all the files and write directly to memory. Not to diminish your achievement, but I didn't immediately see anything interesting here.
Can you explain a bit more? What I meant more-so was the math of a "piece" from a torrent is a fixed number of bytes. The way the files are laid out for a torrent, they are listed in some order in the initial torrent file, along with their individual lengths. The data for the torrent is then treated as the contiguous sequence of bytes for the files in the listed order. That contiguous sequence is then broken into "pieces" of whatever fixed size.
So finding which file s and what position within those files piece , for example, goes to involves some math that is pretty straight forward all in all, but is still rewarding when it's the first time you've done such a thing. ScarZy on Jan 5, parent prev next [—]. Strictly leeches does not support uploading pieces Be careful with using this client the swarm for a Linux ISO is probably a bit more forgiving, but you may get banned very quickly by the tracker or other clients, because they will definitely notice that.
I will put it back to life at some point, but it grew quite big and became very time consuming for a single developer. Looks like a good idea to implement something from scratch to improve the understanding of a language and also a tool. Any other ideas about stuff to implement? I built an http server and a markov chain library to learn python. They're both pretty worthwhile weekend-size projects. I heard cryptopals  is really good for learning both crypto and a new programming language.
Crypto stuff indeed sounds interesting. I implemented a blockchain-based cryptocurrency for fun. It sounds cliche but the details are surprisingly complicated: what exactly do you use as the criteria to determine whether you should accept a block? What are the ways a malicious actor can try to send you an invalid block? Just how exactly do you confirm a double-spending attempt? How do you pick a block based on which to mine a new block?
BookPage on Jan 5, parent prev next [—]. I noticed my terminal emulator Terminator is a python app. I now have a todo item to try and write my own! Excellent write up and very readable code. I noticed a few things with the Go code that confused me.
I haven't coded in Go in quite some time, so I may be way off. Doesn't it overflow into other data elements? Also, and I may be wrong, in the following line, it appears that you are casting to a byte when it's already a slice of bytes, which should still be fine. I'm not done with the article, but I love it so far. It's really helpful. Also, copy will never overflow because it will only copy up to the length of the shortest buffer. I've removed it.
I played with this it requires go 1. It has no command line options and crashes if no options are present. It also doesnt support magnet links, only torrent files. Can you describe the process of learning two concepts simultaneously? Or you knew before the parts of Bitorrent and how to implement it in some other language? Great write up, very clear explanation about the torrent protocol, and nice to see the rational behind certain code decisions.
Any resources for doing the same thing in python? Can it be done in node. Use proxychains for this. Any sources regarding failed interview? Googles ha-ha says nothing. May be the down-voters think I'm a troll? I thought it was an interesting note about the creator of a protocol responsible for a third of all Internet traffic.

Install the library package with go get github. There are some small examples in the package documentation. Communication about the project is primarily through Gitter and the issue tracker. Note that the godo command which is invoked in the following examples builds and executes a Go import path, like go run. The contents are the torrents described by the torrent files and magnet links at -metainfoDir. Data for read requests is fetched only as required from the torrent network, and stored at -downloadDir.

I have been testing this library using an in-memory lru cache with a small readahead time. One of the issues I have observed is that when chunks get evicted from the cache and the piece completion state changes, if I then seek back to try to re-download those chunks, in a lot of cases the peers end up getting banned, and the download seems to hang for a long time.
I see a bunch of messages like this in the logs:. My theory is that chunks arriving after piece is marked for hashing are added to the dirty list after it's already cleared in preparation to be hashed. Later when the pieces are evicted from the cache, a piece check fails and those peers that sent late, overlapping chunks are being banned despite being innocent. If your cache was small enough, and chunks were redundant, and hashes took a while, this would occur quite a lot.
I think the solution is to disallow writing chunks while piece checks are pending or active. I want to use the torrent library in a project that will distribute files across a number of heterogenous storage nodes. Now, after adding a torrent, the client starts hashing. I expect 10x the performance I can see from the torrent library, and thus assume that I'm doing something wrong. Can you provide some help? I used torrent download -seed 'magnet:? If I try to download the torrent using instant.
And immediately after those logs, I am unable to download the seeded file via WebTorrent using the websites mentioned above. When running on Windows, after minute of downloading, I get non stop error messages that keep scrolling infinitely. When I restart torrent, it works ok, but after 1 minute the same happens again.
When I checked the network activity of the torrent process after the error kicks in, I find out that it "loses" all UDP connections and only TCP connections remain active. This might be an error in UDP socket implementation for Windows in the network libraries you're using.
Or something else. The goal here is to discuss and suggest usability improvements to the API. I believe these changes could also be used to help resolve , in a clean fashion. With latest builds for example H and R blocks loaded faster then N and even A - and there is video streaming issue because A block must be completed before play cursor. Last version TorrServer loaded blocks as expected was probably 1. Is there a way to implement piece load order in current torrent code?
When I open QB to start downloading files, the download speed is 0, because there is no seed service. Then when I keep starting the seed service, QB can instantly download some chunks, but then the download speed becomes 0 bytes. On the other hand, if I create a torrent for the same file from in a browser-based webtorrent client such as instant.
I've noticed some differences in the torrent file being created with my code compared to the one created for the same file with instant. I think these differences might point to the reason why seeding from my module seems to be incompatible with the browser client, and why download start is so inefficient in my go module. At ozon. We've chosen this library because it seems to fit our requirements and works well, but in our case some parts of code need to have some changes to provide more flexibility.
Observability is such a crucial thing for our environments and we need to have answers to questions like this:. And there are some webseed metrics which we want to be available as well, but due to the privacy of httpClient we can't intergate our logic. We also want to provide a custom metrics, request modification in the custom client. In the pull request below a client turned to the interface in order to be easily extended by the client code note that there is a mark "need advice here".
In my opinion a webseed client can have different requirements than a client which requests a torrent file. In the code I've tried to make as little changes as I could in order not to break current customer API design. See message banning I see that it's happening during hashing pieces it does re-check all files hashes.
