Anybody knows about one bandwidth meter to use in Bering.
This is a script i built, it's works wel, but it's not very nice!!!  =3DP

#!/bin/bash

# Bandwidth Monitor

device=3Deth0

bytes=3D`grep $device /proc/net/dev |  cut -f 2 -d : | cut -d ' ' -f 2`
kbytes=3D`expr $bytes / 1024`
actual=3D$kbytes

i=3D1
x=3D0
total=3D0
while [ $i -le 2 ]
do
    x=3D`expr $x + 1`
    bytes=3D`grep $device /proc/net/dev |  cut -f 2 -d : | cut -d ' ' -f 2`
    kbytes=3D`expr $bytes / 1024`
    valor=3D`expr $kbytes - $actual`
    actual=3D$kbytes

    if [ $x =3D  5 ]
    then
        x=3D2
        total=3D$promedio
    fi

    total=3D`expr $total + $valor`
    promedio=3D`expr $total / $x`

    echo actual: [$valor Kb/s] - promedio: [$promedio Kb/s]
    sleep 1

done

Best regards.
