...separate location a fair share of the bandwidth (in relation to their student count) with as a ceiling the 6 mbit maximum. As a complicating factor there is also a DMZ connected at LAN speed (100 mbit). So what I did was make a root class of 100/100 mbit, subclassing it in an Internet class off 6/6mbit and a DMZ class of 94/100mbit. The default class is the DMZ class. The Internet class is subclassed further to make a class per unit. I''ve enclosed the script below, it has worked well for 2 years now.... but there are changes at the horizon :D The 6mbit Internet connection has been full...

Hi When I list all the qdisc with tc command it is not possible to see the parent of the qdisc. An example by the book. # tc qdisc add dev eth0 root handle 1: htb default 30 # tc class add dev eth0 parent 1: classid 1:1 htb rate 6mbit burst 15k # tc class add dev eth0 parent 1:1 classid 1:10 htb rate 5mbit burst 15k # tc class add dev eth0 parent 1:1 classid 1:20 htb rate 3mbit ceil 6mbit burst 15k # tc class add dev eth0 parent 1:1 classid 1:30 htb rate 1kbit ceil 6mbit burst 15k # tc qdisc add dev eth0 parent 1:10 handle 10: s...

I've got 2 internet connections but unfortunately not the same - 6mbit and 1 mbit. My default is 6mbit and I want to create backup connection (1mbit). How can do it? Has anybody done it? My perfect scenario is that my network uses 1mbit if (only) 6mbit fails and it switches automatically. -- This message has been scanned for viruses and dangerous content by MailScan...

I''m trying to implement something similar the the diagram in section 9.5.2.1 in the LARTC HOWTO, but must have missed something somewhere :( I''m trying to hack up wondershaper, as it looked like a good place to start.. Here''s where I currently at, but I''ve tried alot of different things, all failing, some worse than others. The end result is to throttle back 126

Hey guys, I have several Linux routers in place at high-usage locations (student apartment complexes). I''m having trouble with some of the routers which use 6Mbit DSL lines as their Internet feed. The routers use PPPoE and perform NAT. During peak usage periods, the routers are dropping alot of packets. I''m lead to believe this is because there are too many active connections. For example, when I ping the WAN IP address of one of the routers fro...

Hello everybody! With a HTB qdisc: # tc qdisc add dev eth0 root handle 99: htb How can I change the "final qdisc" of the default walk-throught class? # tc qdisc add dev eth0 parent 99:0 handle 88: sfq results in: "RTNETLINK answers: Invalid argument" CBQ automatically creates a xx:0 root class where I can attach final qdiscs... - If there is a root class in htb, how is it

Hello I am using htb (krenel 2.6.14.3 + esfq patch from fatooh.org) to limit the bandwidth. But I want the absolute maximum rate to be for example 5Mbit and not to exceed it. here is the script: $tc qdisc add dev ${NETIF} root handle 1 htb r2q 4 $tc class add dev ${NETIF} parent 1: classid 1:21 htb rate 5Mbit ceil 5Mbit $tc class add dev ${NETIF} parent 1:21 classid 1:101 htb rate 2Mbit ceil

My situation: I have a cable modem (COMCAST 6Mbit d/l) and am about to also have DSL (Verizon 3 Mbit d/l).

Hi I am search a sample config for my linux box: Shorewall 3.2.3 Eth0 => Internet Access 4Mbits on ethernet Eth1 => Lan Eth2 => Lan 2 Eth3 => Lan 3 i want limit the internet access: Eth1 = 2 Mbits Eth2 = 0,5 Mbits Eth3 = 1,5 Mbits but if eth1 don''t use 2 Mbits other lan can use it anyone have a simple sample config for help me ? Thanks bye

Hi! Is it HTB fully compatible with BOND interface? I have this setup (mode= fault tolerance) : BOND0 -> ETH0 + ETH1 BOND1 -> ETH2 + ETH3 ( http://www.kernel.org/pub/linux/kernel/people/marcelo/linux-2.4/Documentation/networking/bonding.txt ) HTB work very well with Class over BOND0. If I add Class for BOND1 it generate balance errors. Also with HTB.init

I have a customer who is complaining about slow SFTP transfers over a long haul connection. The current transfer rate is limited by the TCP window size and the RTT. I looked at HPN-SSH, but that won't work because we don't control what software the peer is using. I was thinking about coding a much more modest enhancement that just does SO_RCVBUF for specific subsystems. In the interest

Hello, I''m trying to setup what I thought would be a fairly basic tiered shaping system. I have a 6mbit (768kbps) link coming into my eth1 device, with my LAN IPs on the eth0 device. I want to limit outgoing traffic so that certain IPs are limited to 400kbps, with 3 classes under that 400k so certain machines get prioritized (main servers in 1:21, other servers in 1:22, workstations in 1:23) The...

Hopefully this is not too off topic. I have a server in which I'm creating an Exchange Information Store backup using ntbackup. The .bkf file it creates is 112GB. My goal was first to rsync it over to a local linux server, and then rsync just the changes over the internet to another linux server. I do this with other Exchange .bkf files (in the 4GB to 20GB range) and it seems to work well

I currently have a 6mbit DSL line with a /28 block of static IP numbers. My DSL modem is in bridge mode, so I do not have a router. Because I dont want to put all my machines directly on the internet without some kind of firewall, I put a Linux machine between my DSL modem and my LAN, like this, DSL Modem --> eth0...

...p upload traffic. I limited it to 4Mbit/s. I also set up iptables counters chains in FORWARD chain to calculate traffic generated by p2p and others. While tc stats show that p2p shaping class keep defined 4Mbit traffic, iptables counters show me that p2p traffic exceed traffic to 150% and is about 6Mbit/s. Ofcourse I revised twice all configs but no mistake found.
