Trickle is a simple program to put limits on how much bandwidth a program can use.
Because sometimes you don't want to allow programs to monopolize your internet connection.
To install trickle, first you need to add the Xandros repositories. Adding Additional Software Repositories
Then install with apt-get. (Thanks to PyAvatar on the forums)
sudo apt-get install trickle
then, to use it, type:
trickle -d <download limit, in KB> -u <upload limit in KB> <command>
so, to limit firefox to 10KB up and down, you would type:
trickle -d 10 -u 10 firefox
Trickle may also be used in daemon mode to limit more than one application. More information can be found here… Debian.net Article
