This list of trackers, along with a torrent info hash (such as ae8fb99f41b99da0818108897e07ec7fb8ebc63d) can be used on tools like romanr.info/magnet.html to make fully functional torrent magnet links.
How this list was obtained
I started from an old, much larger list that I use to add to my torrent downloads, then I filtered them based on how they respond to my torrent client (Transmission). Here is the Shell+Perl script, documented for myself, on how to obtain it again:
for s in `seq 100 285`; do
transmission-remote 9091 -n user:pass -t $s -it;
done | perl -e '
while (<>) {
chop;
if (/^$/) {
print "$t\n";
$t=""
};
if (/Tracker \d{1,3}\: (.*)/) {
$t=$1
};
if (m/Got a/) {
$t="$t|$_"
}
}'
Then the result is sorted and filtered in a spreadsheet based on each server’s response. Removing the non-responsive servers and keeping the ones that responded at least zero seeds. Then I manually added the trackers that appear on http://coppersurfer.tk.
