Revision as of 12:12, 30 January 2023
This page describes the BitTorrent library "libtorrent-rasterbar" by Rasterbar Software (Arvid Norberg) but not the similarly named BitTorrent library "LibTorrent" by Rakshasa.
libtorrent-rasterbar is a BitTorrent library written in C++. It is used by popular clients, such as qBittorrent (Qt) and Deluge (Python).
I2P Support
The I2P support is available through the SAMv3 bridge in libtorrent. It was broken until late 2022 after a thread on zzz.i2p[1], resulting in several patches being merged upstream[2][3].
Issues
Currently (early 2023), the peer count shows the right numbers, but the peer list (both in libtorrent's client_test[4] and qBittorrent) shows only one peer with an IP address of "0.0.0.0:0".
(client_test shows multiple 0.0.0.0's, while qBittorrent shows only one.)
Examples
libtorrent
For libtorrent's client_test[4] program, the following command can be used to leech/seed a magnet[5] through I2P (by Vort):
examples/client_test --enable_dht=false --proxy_type=i2p_proxy --i2p_hostname=127.0.0.1 --i2p_port=7656 'magnet:?xt=urn:btih:889401025a1c16bbf9d8001ae157679507a87feb&dn=I2P%2B+Universal+Installer+2.1.0%2B&tr=http://tracker2.postman.i2p/announce.php'
You can press 'h' within client_test to see the available options.
qBittorrent
For qBittorrent, until the I2P support is added[6], one needs to build using Jiigen's fork.
Make sure the installed libtorrent-rasterbar library includes the I2P-fix commit. Building/Installing from source is recommended until the release with the fix is tagged and becomes available on most distros[7].
git clone https://github.com/jiigen/qbittorrent -b i2p-support jiigen_qbit cd jiigen_qbit mkdir build cd build cmake .. make sudo make install
And within the Settings->Connection->Proxy, one needs to set "Proxy Type" to I2P, the host/port to SAM bridge's host/port, and needs to tick "proxy for peer connections/host lookups".
(Note: One might also want to enable Anonymous Mode. (Settings->BitTorrent->Enable anon.mode))
