script to change .torrent file tracker ?

[juan_valdez]

Howdy,

I saw the excellent (Windows GUI) BEncode Editor here, bravo ! Unfortunately, I'm looking to do something a little different.

I am hoping to be able to have a command line script (preferably linux capable) replace a single tracker within the b'encoded .torrent file to a different pass key. i.e. http links might be from

private-tracker.com/announce.php?passkey=AAA36E6D84CBA8FDC2A1359A25FA6AAA

to new passkey of

private-tracker.com/announce.php?passkey=BBB6BB55208CEB35A18894855754EBBB

I'm not wanting to change anything else.

I'm sure there have to be some scripts out there to do this, I just haven't been able to locate them yet.

(I plan to drop the resulting modified copy over in another directory that uTorrent is set to scan via "Automatically load .torrents in directory" setting)

Thanks for any pointers, didn't want to hijack the great BEncode Editor thread space.

Hmmz, it depends on language you want to use:

Thanks, looks good. I'm thinking PHP is pretty portable, and wouldn't be running this every 5 minutes, so plenty efficient for my needs.

Also found http://www.carpetsmoker.net/code/download/changetracker.py.txt for those searching this topic, a python "Simple script to change the tracker(s) of a torrent file" . . .

And there is an API here about editing .torrent files: http://torrenteditor.com/

Ahh very nice, I had missed they had a BEncode capable php5 API there. I had glossed over the site once I saw it was an online tool - very nice, but not meeting what I wanted to do.

Good catch Moogly, a php API is hard to argue with

I use a PHP library in the Webui Shell. I got it from DWK. You can find it on utorrent trac:

Also useful, thank you.

Hopefully, folks will be able to forum search on this in the future to help themselves out.
