Hello to all people there . Can i guarantee ICMP respond time no metter how loaded is internet line . i have typical NATed enviroiment like External IP |linux router| LAN - 192.168.0.0/24 i have example setup with IMQ but is it possible to be done also if i attache htb to eth0 and eth1 for example . if i start shaper ping i better that without shaper but it''s not guarantted i mean

i''m trying to limit upload and download but something is wrong(it is about NAT) i will post here my "script" maybe someone could tell me what is wrong my kernel(2.6.9) is patch with imq(linuximq.net) and my iptables(1.2.11) also #flush tc qdisc del dev eth0 root tc qdisc del dev eth1 root tc qdisc del dev imq0 root tc qdisc del dev imq1 root ifconfig imq0 down

Hi, i am running imq + htb on my router , the situation is like this eth0 = uplink to my provider eth1 = 1st customer eth2 = 2nd customer eth3 = 3th customer eth0 has limit 512 and i want to share this between eth1 eth2 and eth3 , but not working , this is the script i used, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ #!/bin/sh

Hello, I''m trying to get my shaper to work, but have only a partial success. Can someone help me with that. My setup unfortunately is not so trivial, but I think some people could have similar one... 1. There is a router connected to the internet line via interface eth0 2. There are users connected to the router via two interfaces : eth1 and wlan0 3. All users are assigned private IP

I posted earlier when I noticed that htb was releasing packets in pairs, even though my burst/quantums were 1 pkt. To fix I set HTB_HYSTERESIS 0 in net/sched/sch_htb.c . This gives a noticable gain in upstream worst case latency, for me with 256kbit/s up I used to see +90 sometimes, now it''s +45. For the many who have 128 up it should limit them to +90 rather than +180. Andy.

i''m trying to limit my egress bandwidth over 2 interfaces (eth1 and eth2) to 2 Mbit my script is something like this: tc=/sbin/ip ipt=/sbin/iptables $tc class add dev imq0 parent 2: classid 2:4 htb rate 1845Kbit quantum 3000 $tc filter add dev imq0 parent 2: protocol ip handle 4 fw classid 2:4 $tc class add dev imq0 parent 2:4 classid 2:40 htb rate 0.5Mbit quantum 3000 prio 5 $tc qdisc

What''s wrong... I have Celeron 633MHz nd 768Mb RAM. When I''m running my script everything is OK, but when I''m connecting Internet and LAN link computer is hanging. But when i dissconnect this everything is OK. I have 500 users, 1500 classes and 3000 filters. Is it normal? What should I do?

Hello everyone. CONFIGURATION DESCRIPTION: I have a linux box doing masquerade for two lan''s.

Hi all ! I''m building a network appliance whose goals are to enhance Voip quality on 512/128k DSL links. But, i have a voice quality problem, and i think i''m doing something wrong, but i can''t find what. Please excuse my terrible english, i''m french. >From what i''ve read, tc is the tool i need. I read the documentations, readmes and lartc.org

Why am I getting giants on imq0?

Andreas, Since I understand your ASCII art and comments, I would very much appreciate it if you would draw what you see and criticize the following. Hopefully I''ll better understand after that!

Hello! I have a quite complicated setup. In my network on each interface there is bandwidth limitation for each user. Booth outgoing (on interface itself) and incoming (attached IMQ) traffic. There is main HTB class which limits bandwidth for whole interface and HTB subclasses for each user. Filtering is done with hashing filters. This setup was working correctly. But now in the network I

Hello, I wrote a simple traffic shaping script (below) that should have allowed me to shape my internet traffic a bit (ppp0 - adsl 128kbit/64kbit; local interface eth0). The script works only partially - the speed is being limited but too much. Without running this script my download rate is about 10kBytes (with second computer also downloading at about 6kBytes). After running it my download speed

Hello, I have HTB on IMQ device. My rate does not work as I configured. I configured 1920kbit/s and I can download only about 290kbit/s (while it should be the whole bandwidth). My script: /sbin/modprobe imq numdevs=1 /usr/local/sbin/tc qdisc del dev imq0 root 2> /dev/null > /dev/null /usr/local/sbin/tc qdisc del dev imq0 ingress 2> /dev/null > /dev/null /sbin/ifconfig imq0 down

Thanks, The only issue here is that for each service I need to create 200 child classes if I have 200 clients... Let me explain the problem better I have the following connection from my ISP: (1024/1024) (rate/ceil) 1) First, I want to divide the 1024 into smaller pieces based on priority: 256/256 - P2P (I want to limit the P2P traffic as much as possible) 256/1024 - HTTP 256/1024 - FTP

Hello, I have a serious problem with HTB which I wasn''t able to solve myself. I run a masquerading router with ppp0 as interface to the Internet. Three clients need to share a downstream of 1 MBit, which I want to divide with tc. When I see a packet being forwarded to one of these clients, I give it the appropriate unique mark: iptables -t mangle -A FORWARD -d 192.168.34.141 -j MARK

Hi All, I''m trying to create a contended section of bandwidth using IMQ. I have the imq0 device up and running, with traffic passing through it. Firstly, I need to throttle the entire device imq0 to 2mbit/s. I would then like to add throttle rules for individual IP addresses, allowing them to pass up to 512kbit/s each, as long as imq0 has not reached its 2mbit/s. The configuration

I''ve done some tests with TC FILTER and his PRIO and think that is an error or OMISION on TC FILTER DOCUMENTATION from: http://lartc.org/howto/lartc.qdisc.filters.html#AEN1100 Let''s say we have a PRIO qdisc called ''10:'' which contains three classes, and we want to assign all traffic from and to port 22 to the highest priority band, the filters would be:
