similar to: TEQL and Subnet problem

TEQL and Subnet problem I have a network topology shown below, and I am trying to use TEQL. P1, P2 and P3 are three linux machines, and each has two network cards. P2 and P3 are connected in two ways: (1) directed connection between P2.eth0 and P3.eth0; (2) connection via P1. P1 acts as the gateway. TEQL is installed on P2 and P3 to load-balance packet transmission by round-robin sending packets

OK, I spammed the mailing list recently, but I will be fired if I can''t solve the problem today. (just kidding, but I did waste lots of time on it :( ) The common configuration for teql is for two computers connected directly with two links. My topology is a little different: one link is connected directly, but the other is connected through a gateway. My problem is teql can''t

Yesterday I posted a question, but I guess too much detail is provided that no one would bother to read, so I rephrase the question and hopefully some one may be willing to read. Sorry to spam. I am using TEQL on two computers, each with two network interfaces. The two eth0 are connected directly, and the two eth1 are connected via a gateway (a linux machine). The problem is that when I send

Hi there, I have two ethernet connections of 2Mbit/s each and I''m trying to add them together to one 4Mbit/s connection but I cannot get more than approximate 1Mbit/s! My setup: I have a LAN (10.2.18.0/24), connected to a larger network (10.0.0.0/8) by two WAN-connections with 2Mbit/s each. On each end I have a Linux router. I first setup the routers to use TEQL with one of the

Hi to all, +-------+ eth1 +-------+ | |==========| | ''network 1'' ----| A | | B |---- ''network 2'' | |==========| | +-------+ eth2 +-------+ A and B are routers # tc qdisc add dev eth1 root teql0 # tc qdisc add dev eth2 root teql0 # ip link set

Okay here is my setup: Gentoo Box running 2.6.4 w/ 4 NICs 1 NIC is for internal network 3 NICs are for external network The machine has a static address assigned to the internal network nic. This nic runs dhcp and dns forwarding. The other 3 nics have external dynamic IP addresses. All will have the same gateway. There are 3 NICs because this is a very large pipe, that will only allocate a

Thanks in advance! Summary: when I load netem and teql together, teql doesn''t work correctly. (If I load teql only, everything is fine) I loaded both netem and teql. Netem is associated with eth0, and teql is associated with both eth0 and eth1. But traffic only goes out of eth1. Attached are the commands that I used to configure teql and netem (on machine 1), and commands to

Sorry this is the right message. Hi all, in my school I have: - two Netopia router for ADSL (perform NAT), - one linux box with 3 ethernet card I want to make a load balancing on the two ADSL line. I have configured the system as follow: The LAN interface, of the two ADSL router, have address (A) 192.168.0.254 (B) 192.168.2.254 The 3 ethernet card, on the linux box, have address: -eth2

I''am using the following script to aggregate the bandwidth of one quad gigabit ethernet controller (pci-express). #!/bin/bash sysctl -w net.ipv4.tcp_reordering = 30 ifconfig eth1 up ifconfig eth2 up ifconfig eth3 up ifconfig eth4 up modprobe sch_teql tc qdisc add dev eth1 root teql0 tc qdisc add dev eth2 root teql0 tc qdisc del dev eth3 root teql0 tc qdisc del dev eth4 root teql0 ip link

I''m trying to follow Chapter 10 of the howto and apply it to two ubuntu machines each with two 802.11b/g interfaces. However, I cannot get a connection. I would like the 4 interfaces to create 2 ad hoc links on separate channels. I have set this up successfully with the following: /etc/dbus-1/event.d/25NetworkManager stop wlanconfig ath0 destroy wlanconfig ath0 create wlandev wifi0

Hello, After reading the excellent HOWTO I got traffic shaping working nicely over ethernet devices on a test setup. I can''t put this setup live though, because our main firewall has three 2mbit hdlc interfaces instead of a single device. We are using multipath routing using iproute2 nexthop at the moment, and that works fine for firewalling. But now I have a need for shaping and

Hi all, I want to implement a "weighted" teql that can send packets to interfaces based on their "weights". To do this, I want to create multiple virtual network interfaces, and add them to teql. Since teql will send packets to each interface in a round-robin way, a weighted teql is achieved (my guess). I already have two physical network interfaces, eth0 and eth1. I

Hi everybody, I want to do the following setup : | | Tun1 - Link 1 | Tun1 | | Router A | teql | INTERNET Link - | | teql |router B | | Tun2 - Link 2 | Tun2 | | This should permit to agregate Link 1 and Link 2 (less the cost of the encapsulation). The two tunnels are GRE ip tunnel. It seems to work fine

Dear Gurus, Can you please help/guide me with the following: I have 3 NICs in my Linux RH 9 (kernel 2.4.20) machine. (eth0, eth1 and eth2). I want to setup a 'link equalizer' (teql) between eth0 and eth1. This I am able to do with the required commands (using the utilities 'tc' and 'ip'). Now I need to setup a bridge between eth2 and this new interface

Dear List, Another noob question today! I''ve been using iproute2 for a long time now to manage bandwidth and directing traffic over multiple interfaces based on source routing. I am working on a test-project at the moment, in witch I want to actually bundle (''trunk'') some connections. In the LARTC-manual I found the chapter about TEQL (see chapter 10). The situation

I''ll take it from the begining... About one year ago I only had 1 IP and used wondershaper. It worked great. Now I got /27 (32 IPs) and a gw computer that talks to two ISPs via a two tunnels. See: http://www.flashdance.cx/pics/flashdance-LAN.png I _really_ have a need to do QoS on my connection, for example I host websites that uses all available upstream. When I download at the same

I have a centos 4 i386 machine that works like a router (iptables filter, NAT) with two NIC''s. One NIC is connected to my ISP (100 Mbit FTTH), I get a DHCP assigned public IP that changes "sometimes". Most incoming ports are blocked by my ISP. In order to get a fixed IP and open ports, I have to set up a PPTP tunnel to the ISP. The default gw and the NAT''ing goes to

hello , i''m currently trying to set-up Traffic Shapping with Shorewall and I have strong feelings that I found a bug. I may be mistaken, but I tried everything and can''t get it to work. I''ve turned ON TC_ENABLED=Yes and CLEAR_TC=Yes when i start shorewall ( shorewall start ), i get this message : Setting up Traffic Control Rules... TC Rule "2 eth1 0.0.0.0/0 tcp

Hi! We have 2 lines with 2 mbit each. I have to set up a configuration like the following: - if both lines work, grant 3 mbit to a web service running on a server in our DMZ - if one line fails, grant all the remaining 2 mbit to that service - if the service doesn''t need all the bandwidth, use the remaining for other services I read through the HOWTO, and figured out that I need TEQL to

HI, I have a problem with nat on teql devices, i set the nat on iptables and he''s accept well , but don''t work ... he don''t masq or nat anything, i try using -j MASQUERADE too, but without results.. i m using the command: iptables -t nat -A POSTROUTING -j SNAT -s 10.0.0.0/24 --to ip-teql-device On kernel 2.2x with ipchains works great.
