Shell Programming and Scripting

Hello everybody,


i try to control the downlink of my computer via wondershaper. I want to set the downlink every two seconds.


Therefore i have a the following example file, with the downlinks, that should be set:

Code:

1000
2000
3000

In this case the downlink should be limited from 0s - 2s to 1000, from 2s - 4s to 2000, ...


I tried to write the following script to execute wondershaper every two seconds, according to the file:

Code:

#!/bin/bash
while read LINE
do
   wondershaper eth0 $LINE $LINE 
  sleep 2
done<$1

But when i execute the script with the file as parameter, i got the error massage: Illegal rate ...
I don't know why this messages appears and i hope someone can help me here.

wondershaper, some versions I think, requires command line switches. For example

Code:

-a : network card name
-d : download rate
-u : upload rate

Perhaps try adding the correct command line option?
