Re: [LARTC] Load balancing / Traffic shaping project looking for help
This looks really nice! I really would like to try it out, but there is no code on the sourceforge site released yet. Unfortunately I am not the person you are looking for as my understanding of the advanced routing concepts is not that good yet, thats why I am interested in your tool :) How much of this actually works? micah On Wed, 12 Jan 2005 12:59:07 -0500, Aaron Wolfe <[EMAIL PROTECTED]> wrote: > Hi, > > I've managed to create a web based interface to some of the advanced > routing capabilities in Linux.

Re: [LARTC] realtime trafic monitor
I've found pktstat to be almost exactly what you are looking for.

[LARTC] Shaping weirdness
I've been following the HOWTO, and reading mailing list discussions
about throttling bandwidth, and have had some success, but I just want
to tie off some loose ends. Essentially what I am wanting to do is to
keep our bandwidth usage below 1megabit, because if we go over we get
charged for that traffic. I've used some of the examples from the
HOWTO to limit our bandwidth, but I find that it gets limited to
*half* what I specify. If I specify 256, bandwidth tests (using iperf)
show that things are clamped at 128, that makes me scared that I am
doing something right.
I'm using cbq, I've seen some people suggest using htb instead because
it is more reliable and easier to configure, but I thought i'd get
what the HOWTO says working first, and then investigate alternatives.
I've got a machine that sits in front of the network, has the internet
plugged into eth0 and the other side plugged into eth1, and I am doing
the following:
#!/bin/bash
LIMITDOWN=256
LIMITUP=256
DEV=eth0
DEV2=eth1
# clean up qdiscs
tc qdisc del dev $DEV root 2> /dev/null > /dev/null
tc qdisc del dev $DEV2 root 2> /dev/null > /dev/null
# limit up- and downlink
tc qdisc add dev $DEV root handle 1: cbq avpkt 1000 bandwidth 100mbit
tc qdisc add dev $DEV2 root handle 2: cbq avpkt 1000 bandwidth 100mbit
tc class add dev $DEV parent 1: classid 1:1 cbq rate ${LIMITDOWN}kbit \
allot 1500 prio 5 bounded isolated
tc class add dev $DEV2 parent 2: classid 2:1 cbq rate ${LIMITDOWN}kbit \

tc class add dev $DEV parent 1: classid 1:2 cbq rate ${LIMITUP}kbit \

tc class add dev $DEV2 parent 2: classid 2:2 cbq rate ${LIMITUP}kbit \
