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 net...

...39;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 connections and it works with 2Mbit/s, then I test the other connection with TEQL and it works fine to, but then I add both connections to TEQL and then the speed go down to 1Mbit/s. WAN router: # Connected to the 10.0.0.0/8 network eth0: 10.1.1.118/24 eth1: 10.2.20.1/30 # First W...

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 packets through teql0 to the other machine (ping -I teql0), the packets can''t go through eth1 and all pac...

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...

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 in theory : I manage to send packet on the...

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 'teql0'. This is not possible as 'teql' is not a 'bridgable' interface. Is it pos...

...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 create a virtual device that can have HTB attached. My questions: - how will bandwidth granting work with teql? Will the bandwidth be additive and then granting and borrowing possible? - if one line fails, how what will happen? I guess that the failing device (e.g. eth1) will go offline, and th...

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 send packets through both links at the same time. When I don''t configure a gateway for...

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....

...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 shaping only works over a single interface it seems and not over multiple interfaces. According to the HOWTO I can setup a teql device to bundle the hdlc0-2 into a single teql0 device, but that requires an extra combined IP address at both sides it seems. The question is whether I can get away with setting up the teql device over the three hdlc IPs with an ip on the teql device that''s either fake or one of our...

Is it possible to detect if a link is down in a TEQL device, so that I will receive a mail on such occasion? TIA -- Groeten, Joost Kraaijeveld Askesis B.V. Molukkenstraat 14 6524NB Nijmegen tel: 024-3888063 / 06-51855277 fax: 024-3608416 web: www.askesis.nl

Hello list, I''d like to use teql with tap devices (two OpenVPN tunnels). This works, but the doc /usr/src/linux-<version>/net/sched/sch_teql.c says: "1. Slave devices MUST be active devices, i.e., they must raise the tbusy signal and generate EOI events. If you want to equalize virtual devices like tunnels, use a norma...

...n the linux box, have address: -eth2 172.16.255.254, connected to a switch and operate with VLANs -eth1 192.168.0.2, directly connected to the router (A) -eth0 192.168.2.2, directly connected to the router (B) The routing with router (A) or (B) work fine. I want to do a load balancing using teql I have configured the qdisc and teql as follow #ip route del default #tc qdisc add dev eth0 root teql0 #tc qdisc add dev eth1 root teql0 #ip addr del 192.168.0.2 dev eth1 #ip addr del 192.168.2.2 dev eth0 #ip address add 192.168.0.2/24 dev teql0 #ip address add 192.168.2.2/24 dev teql0 #ip link...

hi, I''ve encrountred some problem with iproute2... I''m building a router with kernel 2.4.20 but my script fail when I try to do a load balancing over a specific traffic, how explained on LARTC for balance the access between more link we should simple: ip route add default scope global nexthop via IP1 dev ETH0 weight 1 \ nexthop via IP2 dev ETH1 weight 1 for specific traffic

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. TE...

...all 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 studied similar problem? What makes the performance go down? I use Fedora Core 3 and 4, teql and netem for my emulation. _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

...sing 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 in that example is too link 2 networks. I need to link a network to 1 remote gateway. The problem I can''t solve on my own is that you can only add physical devices to the teql0 qdisc. Therefore the following won''t work: +--------...
