Limiting uploads as a ratio using btlaunchmany

madtinkerer · 09-14-2006, 09:39 AM

Hi all,

I'd like to be able to limit uploads of bittorrent transfers by their upload ratio rather than upload speed. For example, I would like to launch a btlaunchmany command and have the program run until it is reached something like a 5:1 upload/download ratio, or has been seeded for a week, whatever comes first. I checked the man page for btlaunchmany but there doesn't seem to be any way to limit seeding according to the up/down ratio. Any idea how to do this?

That's a damn good attitude, let's try and support that...

Any idea how to do this?
Here's a slightly different approach because I use btdownloadheadless.
It should go for .*many as well as long as it uses --spew which sets the logfile.
If you "reverse cat" (tac) the logfile and grep for the first string "upload rate:" and take the 3rd value you have the most current amount for upload. Take the archive/file size from running btshowmetainfo, mangle a bit, and you get:

Code:

#!/bin/sh
# where your running torrent files and logs reside
torrentdir="/var/bittorrent"
find "${torrentdir}" -type f -maxdepth 1 -iname \*.torrent | while read t; do
 if [ -f "${t%%.torrent}.log" ]; then log="${t%%.torrent}.log";
  u_size=($(tac "${log}" | grep -m1 "^upload total:")); u_size=${u_size[2]}; 
  t_size=($(btshowmetainfo.py "${t}" | grep -m1 "^[fa].*size")); 
  t_size=$(echo "scale=2;${t_size[2]}/1024/1024"|bc -l); f=${t//*\//}; f=${f%%.torrent}; 
  echo "${f} uploading:$(echo "scale=2;(${u_size%%.*} / ${t_size}) * 100"|bc -l)%"
 fi
done
exit 0

This is more like PoC and not what you want exactly, but it should be trivial to turn the output line in to some check-and-execute thingie.

Trivial for someone with 8,000 posts, not for one with about 5 :-) Thanks for the info though, I'll see what I can do with what you gave me. If I run that as a cron job, how do make sure that the torrent isn't activated twice? I'd like to have a directory where i can drop torrent files and have it check for new files every day or so and download them. I know the commands are there, I just can't figure out how to string them together. Thanks for the help again though. Tis always appreciated.

Never was my intention to emphasise that.

and you don't have to be doing that alone.
Here at LQ we've got some real scripting guru's.

If I run that as a cron job, how do make sure that the torrent isn't activated twice?
This script will only help in a situation where torrents are already running.

I'd like to have a directory where i can drop torrent files and have it check for new files every day or so and download them.
That could be done with another script. Just tell us where (what dir) you would like your torrents to be dropped in, and what arguments you run btmany with.

I know the commands are there, I just can't figure out how to string them together.
Yes, annoying isn't it? :-]
