Re: [LARTC] can't get cbq to traffic shape

[Trevor Warren <trevorwarren@softhome.net>]

Hello Stef,

 Thanks a million for the information. Am sending you the modified tc
script that i worked on. This in essence have 2 filters for the incoming
and outgoing packets to 192.168.*.*.

 



#!/bin/bash
