Meta-torrents (those containing other torrents) often have poor tracker propagation due to their small file size (usually under 1MB). To solve this, include DHT and PEX (Peer Exchange) in your client: lsm file list torrent torrent

1. The Problem (The "File List" & "Torrent" Bottleneck) In a standard BitTorrent system, the server (tracker) or the client must maintain a massive list of metadata: In practical terms: you download a
LSM File Lists: Researchers often work with large "Z-stacks" or time-series data, resulting in extensive lists of .lsm files for a single experiment.
mktorrent -a udp://tracker.opentrackr.org:1337 -l 20 -o myarchive.torrent /your/data
In practical terms: you download a .torrent, inside its contents (or as a separate text file) there is an example.lsm file that lists every single file in that torrent, with checksums.
cat manifest.lsm | grep -A10 "FileList:" | grep "\.iso"
# Returns all ISO files listed in the archive
