Script to automatically add trackers from a list to all torrents in Transmission. This allows to get more peers to download/upload from/to.

Features:

• Download lists of trackers from any number of URLs and cache them locally. The cache will only be updated after the specified time passes (e.g. once a day)
• Check if trackers obtained from remote URLs are resolvable in DNS
• Load additional local tracker lists
• Remove duplicates so that only unique hosts and IPs are used: if two or more URLs point to the same hostname or the hostname resolves to the same IP - only one URL will be loaded
• Optionally filter torrents by status (seeding, stopped etc)
• Compare the current tracker list of a torrent with the required one and only update Transmission if they don't match

Tracker list format:

• One tracker URL per line
• Empty lines are ignored
• Only http[s]:// and udp:// trackers are loaded (Transmission does not support WebSocket trackers AFAIK)

Requirements:

• Should work with both Python 2.7 and 3.x, although there may be problems with logging in Python2 due to different unicode handling, I don't want to fix that :)
• transmissionrpc Python module

Usage:

• Get transmissionrpc: pip[3] install transmissionrpc (or using any other method)
• Put the transmission-trackers.py script somewhere
• Make sure that the right Python interpreter is used (it's python3 by default)
• Adjust the host/port/credentials to access the Transmission RPC inside the script
• Add your URLs and local files to the appropriate lists in the script
• Adjust other parameters if needed (see comments)
• Make the script run by cron e.g. every minute
• You're done

Cron Setup:

• Open Crontab using crontab -e
• For Updating Trackers to Every New Torrent Every 15 Minutes Add: */15 * * * * /usr/bin/sh [path]]/transmission-trackers-auto-cron.sh
• Modify the transmission-trackers-auto.sh file as per your needs. We have provided two options, transmission-daemon & docker
