Hello list, I''m having a little trouble imagining a setup I''ll soon have. I am in the process of getting a routed /28 to my homeLAN. What I want to do is to put a linux box in front of the lan to filter some of the unneeded and potential dangerous ports. Now the box has 2 nics, one for the inside one for the outside. How should I go on to setup those NICs when a) the PCs in

I have three ADSL lines that I''d like to use as one big pipe to the internet. The ADSL service works by establishing a pppoe connection (the ADSL "modem" is a bridge), and each pppoe interface gets its own IP address. This means I''d have to have 4 ethernet interfaces (3 for each of the ADSL modems and 1 for the LAN) in my gateway. I''d setup the gateway to NAT

Hello, I want to share/split bandwidth on a link with unknown bandwidth. I want to exactly share/split bandwidth (for example : FTP 30% , HTTP 20% or 30% for a group of PCs and so forth.) "Traffic-Control-HOWTO" talk that PRIO scheduler is an ideal match for "Handling a link with a variable (or unknown) bandwidth". But PRIO scheduler can not exactly share/split

Greetings, me again. I''m starting to feel miff now. If I have a few vpn tunnels with different tun interfaces. And all this tunnel traffic is coming in on my eth0 interface, it also leave via eth0 again. I would like to share the available bandwidth evenly with tunnel clients. Would applying the bandwidth rule on eth0 with htb & sfq work for sharing the bandwidth or will

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

Hi: I am using a machine with the 2.4.26 kernel, and trying to compare the performance of the HTB qdisc with the HFSC one. I have the following simple script that allows me to have a video stream on port 1234 while it limits a ttcp UDP stream so that the video stream is unimpaired. #!/bin/bash tc qdisc add dev eth0 root handle 1: htb default 12 tc class add dev eth0 parent 1: classid 1:1

Hi, I am not sure if this problem has already being posted, but I haven''t found any solution. Excuse me if it''s a repost but would appreciate any pointers. I have newly configured Multipath default route. I have 1 local connection and 4 internet connections. I am using kernel 2.6.7 and have applied Julian''s relevent patches. When the next hop is down,

Greetings, I want to setup bandwidth restrictions for a few clients that use openvpn to connect to my server. I''m using iptables to mark the packets in the mangle table (PRE/POSTROUTING) on eth0 before they get sent via the tunnel. Will the mark survive even if the packets then get routed via an openvpn tunnel (tunX) out the box or does openvpn change it removing the mark ? damnit,

OK, here it is. Near perfect bandwidth calculation for ADSL users. Patch iproute2 with the HTB stuff and then this: It''s still a hack (as far as I can tell) because we are patching the rates tables, and hence I think it is only loosly coupled with the actual calculation of bytes in each bucket. However, it works very nicely for me! I have only been lightly testing with

Did anyone see the article? It''s the first time I really noticed that these little Linksys routers are such a fully fledged linux machine with a decent processor and a replacable firmware. I am now itching to get one to replace the multipurpose firewall desktop machine. Has anyone experimented with the current state of the firmware and how advanced you can get with tc rules? For

Well I got mine from http://ftp.iasi.roedu.net/mirrors/ftp.inr.ac.ru/ip-routing/ but I didn''t even know about those 2.6 ones... I''m using the latest 2.4.7 with my 2.6.5

The recent thread titled: working ftp shaping, i think provided a script example where 100Mbps was specified as the rate for a typical NIC. If that NIC is connected to a switch, chances are that it runs at 100Mbps in each direction concurrently - duplexed Writing a rule that specifies a 100Mbps rate and thereby a 100Mbps ceil, limits the connection to half the available bandwidth. I

I''m playing with the rather excellent QOS script from Alexander Clouter at http://digriz.org.uk/jdg-qos-script/ So far I am really impressed with it - a very impressive example of the power of linux QOS rules (has pretty much everything in it from the LARTC Howto!) However, the instructions hint that "for QoS to affect locally generated traffic in a non ethernet bridge setup

Hi I have to manage a network with approx. 200 users, a 256kbit/s unmanaged Internet connection and a 3Mbit/s unreliable managed Internet connection (only http/ftp-proxy and ssh available). All users are in one Class C Subnet with 512 IP-Addresses. 60% of the machines are Windows. The rest are SUN and Linux. At the moment Windows viruses and p2p-traffic eats most of our bandwidth. My Aims are:

Hi all, I''m developing Q-in-Q VLAN feature for a router software. Does any open source tools have capacity of capturing and displaying Q-in-Q VLAN packet?

Hello to everyone, Can someone help me with hints on how to configure a pppoe gateway on a linux box with 200+ clients behind it ? I''ve read that user-space daemons give A LOT of CPU overhead. I''m opened to ANY solution ! -- Radu Cugut mobile: +40 742 045686 web: http://rcugut.has.it

Hello there! Yesterday I started my experiments with HTB. I configured it this way: 1: root HTB qdisc | 1:1 HTB class rate 1000kbit | /-------+------\ 1:40 1:50 1:60 user1 user2 user3 rate 333 & ceil 1000 for everyone. User2 is disconnected and user1 and user3 are downloading. For all the time (t1-t5) there are ONLY these two users downloading! HTB should give

It seems Andreas Klauer''s fairnat has experimental support for using HTB''s MPU and overhead options. fairnat.config: # Use MPU for HTB. From the LARTC Howto on MPU: # "A zero-sized packet does not use zero bandwidth. For ethernet, no packet # uses less than 64 bytes. The Minimum Packet Unit determines the minimal # token usage for a packet." HTB_MPU=0 # HTB_MPU=64

I have a Cable ''modem'' that has a problem that many of these devices is bound to have. I was wondering what other lartc user thought about this and if DSL has simular problems. Cable, being Asymetrical, is able to upload at a given rate and hopefully has a buffer, in the modem, of some kind. When I nc(netcat) to a UDP echo, or discard, server I get about 10Mbps out on my
