[LARTC] [LONG] Weights not working

[Raj Mathur <raju@linux-delhi.org>]

Hi,

The Description
---------------

Am making a package for a VSAT ISP.  Running Red Hat 8.0 with the
updated kernel (2.4.20) and patched for HTB on the bandwidth
management system (BMS).  BMS has two ethernet interfaces: eth1 at
192.168.0.1/24 going to the LAN with PCs and eth0 at 10.9.25.34/28
going to the VSAT uplink.

Kernel HTB version: HTB init, kernel part version 3.10

Using the htb.init script v0.8.4

Throttling total outgoing VSAT bandwidth on eth0 at 64 Kbps.
Throttling total incoming VSAT bandwidth on eth1 at 256 Kbps.

Throttling total incoming/outgoing bandwidth for sets of PCs on the
LAN on eth1/eth0 respectively using netfilter marks.

PC pools on the LAN (IP, Min/Max download bandwidth allocated):
(a) 192.168.0.64/31 (32/128)
(b) 192.160.0.2/32 (128/256)
(c) 192.168.0.3 (32/128)

The Problem
-----------

Throttling is working fine in both directions.  However, when the link
is choked the PCs do not get bandwidth proportional to their RATEs or
CEILs.  So if all the PCs start downloading simultaneously, each pool
gets ~85 Kbps, instead of pools (a) and (c) getting 64 Kbps each and
(b) getting 128 Kbps.

Enclosing the files from /etc/sysconfig/htb and the htb compile
output.  Thanks in advance for any help.

Regards,
