Bittorrent Mainline Port Randomizer / Custom Settings script

Here is a quick and dirty bash script that I used when Bittorrent Mainline removed the random port option.

• The script uses a random port to listen from a given range
• Sets custom upload limits,refresh intervals and client address(IP)
• Disables Linux uPnP
• Changes the default data directory (default is ~/Desktop/Bittorrent)
• Saves the downloaded file to current directory

Copy the code to text file and save it as Bitty.sh and set execute permission with 'chmod a+x Bitty.sh' and launch with ./Bitty.sh <torrentfile>.torrent

You may need to change the values to suit your needs. Also note that the You the /usr/bin/bittorrent-console is commandline client from the bittorrent Mainline for GNU/Linux and change the location on your Linux distro.

#!/bin/sh
#
#
#set -n
# Bitty.sh - a port randomizer for bittorrent mainline
#set -x 
#
MAXPORT=25000
MINPORT=20000

number=0

while [ "$number" -le $MINPORT ]

do 
  number=$RANDOM
  let "number %= $MAXPORT" 
done 


exec /usr/bin/bittorrent-console  --ip debbox.no-ip.org  --display_interval 30 
--no_upnp --minport $number  --maxport 25000 --max_upload_rate 5120 
--max_initiate 70  --save_incomplete_in /mnt/BigMaMa/.bittorrent/incomplete
 --data_dir /mnt/bigMaMa/.bittorrent  --save_in . "$1"

Please feel free to improve the script !
