Maybe a strange request, I''ll try to explain this as clearer as I can (forgive my bad english, please :-) ). I''m setting a linux box as a router. My router uses multiple routing tables, so I can address the traffic from specific ip addresses of my lan to distinct ISPs providers (specifying a different default gateway fo r each table), marking packets with iptables

This is more of a NF question but it is tightly related to LARTC as well. In the following example: -t mangle -A PREROUTING -i eth0 -j MARK 0x1 .... -t mangle -A INPUT -i eth0 -j MARK 0x2 Since MARK is a non-terminatring target, what would be the resulting mark on a packet comming from the outside and destined for a local process? Thanks P.S. I agree, the example looks stupid, but on the

Hello, world! Sorry to subscribe to the list only to immediately ask a question, but this one''s got me scratching my head and I can''t find the answer in the archives, the HOWTO, or on the web. Maybe I''m just asking the wrong question. Anyway, our Internet gateway is a Linux box. We''ve got two Internet feeds, a fast one from a crummy provider, and a

I am developing load balancing router, But I have a question about fail over. The follow diagram is my test environment and scripts. ------------------------------------------------------------------- Environment Setting PC1(192.168.10.2) | (LAN) | PC2-eth2(192.168.10.1) +

Hello, I am attempting to match on a single bit of the NF mark value, and after hours of reading and googling I can not get the syntax right. It got to be something very simple, yet I can''t find it. Any help will be greatly appreciated. Thanks! root@Arzamas:/etc/init.d# tc filter add dev wan_b protocol ip prio 2 parent 1:0 basic match meta\(nf_mark mask 0x80 eq 0x80\) flowid 1:0x80

Hi, I have searched the archives on the topic, and it seems that the list gurus favor load balancing to be done in the kernel as opposed to other means. I have been using a home-grown approach, which splits traffic based on `-m statistic --mode random --probability X`, then CONNMARKs the individual connections and the kernel happily routes them. I understand that for > 2 links it will become

(I know that what I''m wanting to do can be done, but for some reason I can not get it to work for the life of me. I think I have been staring at it too long and too closely.) I have two different internet connections from two cooperating ISPs. I also have a small 8 block of IPs that are globally routable that both ISPs will route to me via my world facing globally routable IPs that

Hi, I have a testing multihome setup, with the default gateway being one of the links and using policy routing to honor requests for a specific link. Everything works as expected when I request a specific IP to bind to. But if I request a specific interface things fall apart in ways that I can not explain: default gw (WORKS) ---------- rabbit@Thesaurus:~$ ping -c 1 yahoo.com PING yahoo.com

Hi, I have a server and ten clients in a Gigabit network. The server has 125mbps network bandwidth. I want that the server has 40Mbps bandwidth reserved for client 1 (IP 192.168.5.141), and the rest bandwidth is for all other clients. My script looks like this (I use IFB for incoming traffic): #!/bin/bash export TC="/sbin/tc" $TC qdisc add dev ifb0 root handle 1: htb default 30

Hello list. I have been trying to figure this out on my own, but I guess I somewhat failed :) A linux router with external eth0 and internal eth1 acts as a gateway for a number of machines utilizing a partial T1 line (512kbps). Since the T1 is limited by hardware and by its nature to 64kbps per channel the most I can pump out of it is up+down < 512kbps. If a number of workstations amount to

Hello, Am writing to the list in the hope that someone out there might be able to help me make sure I have the right configuration here. I''m not all that au fait with routing using multiple interfaces. Some time ago I configured a web server to have two different IP addresses from two different network ranges on each of it''s two ethernet cards. I followed the excellent

Hi, I posted this question yesterday on the Openvpn mailing list, with no response, figured I will ask here too. I have been using openvpn for quite a while, no major problems encountered. Now I need to allow the server to access the lan of the client, and I can not figure out the routing. This is what I have after the tunnel is brought up: SERVER (A.A.A.A) Arx:~# ip addr ... 3: eth1:

Hi, I''ve been implementing a load balancing solution using CONNMARK, based on solution described by Luciano Ruete at [1]. Gracias por el post y por apuntar en la dirección correcta Luciano! Once implemented, I''ve found that due to some reason packets aren''t properly marked (or improperly remarked) and sent out using the wrong interface. My topo setup is:

Greetings to all, To start I’ll firstly lay down the foundation to what I have done so far and if those of you on the list can provide further insight, tips, links etc. This scenario consists of 2 firewalls (both running Debian “etch”), 2 Cisco routers (unsure of model numbers) connected together like so in the diagram below. ----------------------- | Uplink Provider |

Hello all, I have the following problem both at my home network and at work. Once many cleints access a share, and traffic grows up extensively connections start to terminate themselves unexpectedly. It may be an open file or a locked share - either way it reflects a mesaage similar to oplock_break: receive_smb error (Success) oplock_break failed for file John's Publications/Show Price

Hello list, I need to realize a complicated custom shaping setup, and given very little experience with shaping I just can''t wrap my head around it. I am not seeking a complete script, I just need an idea/a set of pointers on how to best subdivide traffic accordingly to my needs, and which shapers to place on every leaf. I am very experienced with netfilter and have minor experience with
