Hi, I am using netem to add loss and then adding another qdisc within netem according to the wiki. Then i want to change the netem drop probability without having to delete the qdisc and recreate it. I try it but I get invalid argument: thorium-ini hedpe # tc qdisc add dev ath0 root handle 1:0 netem drop 1% thorium-ini hedpe # tc qdisc add dev ath0 parent 1:1 handle 10: xcp capacity 54Mbit

I have installed windows printer drivers and it worked but now I need to remove several. I have tried everything I can find but nothing will get rid of them. Using "remove" from a winxp machine in "server properties" won't work. It claims they are in use. I'm not sure what "in use" means. Nothing is printing and the drivers should be local. I've

Hey, fellow LART controlllers, I''d like to ask if someome has a real esfq experience with HTB class hierarchy and esfq qdiscs. Lets say that I want to unite the connections to 10 client PCs with u32 or fw filters (doesn''t matter which one in fact) into one HTB class with esfq qdisc at the end. Did anyone tried it, and more important, did it worked the way it is supposed to? As

Hi, it seems that "ip address delete" will delete all addresses of the same class on an interface if it is ordered to only delete the first one: # ip a f eth0 # ip a l eth0 3: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether xx:xx:xx:xx:xx:xx # ip a a 192.168.a.b brd + dev eth0 # ip a a 192.168.c.d brd + dev eth0 # ip a d 192.168.a.b brd + dev

Hi, I''m trying to set up 15 different delay intervals for packets leaving on an interface, using netems hanging off of a 16-band prio. I''m having trouble adding anything to bands higher than 10. Here''s what I tried: tc qdisc add dev eth0 root handle 1: prio bands 16 \ priomap 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 I want all default traffic to go to

Hi, at my local university network, I have to make sure no student uploads more than x GB/day. So far, I give them unlimited bandwidth until they have more than y GB (y<x) upload. After that, I use the u32 filter to associate the affected IP address with a HTB class limited to the rate (remainingtraffic/remainingtime). Since the accounting is done with ipt_ACCOUNT right now and the netfilter

Hi all, I''m running some tests with netem and I noticed some strange behaviour that looks like a bug: I''m pinging another machine and adding delay with netem. When I tell netem to give me a 10ms delay, it works fine. The problem is that when I ask for a 11ms delay, it gives me 20ms! It happens for any value between 11ms an 20ms, and it repeats for values over 20ms, now

Hi, [sorry for the crosspost, I don''t know whether this is a routing or ebtables problem] I want to redirect all HTTP traffic passing through my bridge to a squid proxy on another machine. However, setting up brouting as suggested in the ebtables examples doesn''t work and the packets get dropped on the floor completely. /\/\/\/\/\/\/\/\ +----------------------+

Hi, I wonder about the performance of a Linux box used as router (I guest I''m not the first :). Althought I know it mainly depends on the hardware, I''m trying to find some references on the topic or comparations with other routing solutions (FreeBSD box used as router, Cisco, etc). For example, http://facweb.cti.depaul.edu/jyu/Publications/Yu-Linux-TSM2004.pdf (althought is

During my tests I''m starting to feel stupid :). Traffic shaping works quite on its own. System: RedHat 7.3, RedHat kernel 2.4.18-18.7.xsmp, HTB version 3.6, interfaces eth0 and eth1 are acting as bridge br0. If TCP shaping almost works, it just exceeds limits UDP is not shaped. Traffic flows PC=>eth0=>eth1=>PC. Statistics shown is for just UDP traffic (1mbit of small udp

Hello one more time, As others seem to already asked without reply, I''m getting lower speed rates than specified via ingress. How do I know. Because I have this in my script: tc qdisc add dev $DEV handle ffff: ingress # Filter intranet traffic, so fit it to intranet speed tc filter add dev $DEV parent ffff: protocol ip prio 10 u32 \ match ip src $Q_2_HOSTS \ match ip dst

Dear All, I need to setup different route with different tos value. I can use the flowing command to add a tos route to routing table. ip route 192.168.0.2/32 via 192.168.0.1 tos 0x1c and ip route 192.168.0.2/32 via 192.168.0.1 tos 0x40 I used "ping -Q" to test it with different tos, the output packet is marked correctly. The problem that is only the tos value defined at

I am measuring the performance of one TCP connection over two symmetric paths. Packets are sent to two paths alternatively. I found that when the latency of each path are within 1ms, the overall TCP throughput is the *sum* of the throughput of the two paths. However, when the latency of the two paths increases to 5ms, the overal TCP throughput drops to the throughput of a *single* path. Has anyone

Hello, I how an embedded processor that needs to act as a bridge between a wireless and wired network. I have managed to bring up the bridge fine. I can also bring up the bridge with a static ip address. However I can not figure out how to bring up the bridge with a dynamic ip address. Is it possible to for a bridge to get a dynamically assigned ip address? Oliver

Hi wondering if anyone can help. I have two NICs on a debian sarge based system and current running as a bridge (br0) which consists of eth0 and eth1. Is it possible to add a virtual interface to the eth1 so I can also do NAT on the box as well? I have tried many times and keep coming up with errors. Kind Regards William Bohannan
