Nefunkcni HTB shaper.

Ahoj, snazim se rozchodit traffic shaping pomoci HTB, ale stale se mi nedari.

Mam linku o rychlosti 2Mbit a chci na ni uprednostnovat vybrany provoz. Rozdelil sem proto pasmo na dve tridy. Prvni tridu pro prioritni provoz a druhou pro ostatni provoz. V prvni tride jsem jeste vytvoril ctyri pasma pro prioritizaci v ramci teto tridy.

Moje konfigurace pro tc:

#!/bin/bash
ORATE=2000
OFACE=ppp0
IFACE=eth1
IRATE=3000
BANDS=4

Problem je, ze pakety nepadaji do prislusnych qdiscu:

tc -s qdisc show|grep -A 2 ppp0

Z vypisu vyse je videt, ze pakety padaji pouze do qdiscu 1:, 11:, 112: a 115: a napr. qdisc 111:, kam by mel padat icmp provoz, zustava prazdny.

K prioritizaci timpadem nedochazi.

V cem by mohl byt problem?

Dekuji.
