Originally created by @tuxayo on GitHub (Dec 25, 2016).

With two machine on the same network with:

qBittorrent version: 3.3.1.0
libtorrent-rasterbar: 1.1.1.0
OS: Archlinux
Boost: 1.62.0
Qt: 5.7.1

LPD wasn't working.
If I manually added the ip, the transfer would start (with the right local IPs)
However, the transfers rate was around 200KiB/s compared to 50MiB/s (limited by disks) usually.

When downgrading to libtorrent 1.0.x on both machine.
Then LPD works by itself and the transfers is around 50MiB/s.

Downgrade instructions for other Arch Linux users:

yaourt -S libtorrent-rasterbar-1_0-git
yaourt -S qbittorrent-git # the qbittorrent official package is linked against the new libtorrent and won't work with the old one.
