similar to: Policy based routing support for IPv6 in Linux

Hello all, I am going through the LARTC howto to understand how the iproute2 works. But some concepts like Policy Routing, RPDB etc are not clear to me. I am pretty new to iproute, beeing using route command for long... From what I understand 1. rules (ip rule) tell how to select packets for routing and route (ip route) tell where to route the selected packets. 2. A collection of rules is

Hello, [I hope i''m on the lartc mailing list - i''m posting using gmane] I used the "Linux Advanced Routing & Traffic Control HOWTO" for doing source routing using iproute2. The documentation would be perfect if the source routing page <url:http://lartc.org/howto/lartc.rpdb.html> mentionned you may have to turn off spoofing protection on ppp2:

Hello all, I do not read C very well (especially kernel C). Though I have tried to muddle my way through an understanding of what''s going on in fib_hash.c, fib_rules.c, and route.c, I have not succeeded to my satisfaction, hence my post. I''m trying to document the general process of route selection, and have come up with the following overview. Could somebody point out any

Hi, I''m sorry for "novice"-level question, but I hope your expert advice will save me many painful hours running after my own tail... Let assume I have Linux box with eth0, eth1 and eth2 interfaces. Each one has IP assigned from different network. By default, IP address associated with eth0 is chosen as default routing. My application creates thee TCP sockets and explicitly

Hi, I''ve set up a Linux box with redhat on to act as an internet gateway and I''m running into a few problems. Its got two adsl modems connected to it, both connected to seperate 512kbs lines. Now I''ve followed the simple source routing in the advanced routing howto to the letter but it doesnt work. I''ve got it autoconnecting on startup and redhat puts ppp1

Hi everybody, I''m trying to set up routing for 2 links to the internet on a box which produces traffic itself (e.g. DNS) and will route all our local traffic. AS one route is quick and expensive and the other one slow and cheap, I want to be able to route packets for some high-level protocols to the second link. If I correctly understood table 3-2 in

Hello all, I am working with kernel 2.2.20 with the necessary options configured into the kernel to support all of the wonderfully fancy routing features: - routing based on ToS - routing based on fwmark - multiple routing tables This same kernel is in use elsewhere, and is routing based on fwmark with success. This leads me to believe that my kernel is OK and that I have another

Hello, Is there a way to route p2p traffic on a separate ISP connection, just as you would choose a separate connection for http traffic? I tried all sorts of setups based on: http://www.braindump.dk/en/wiki/?wikipage=PolicyRouting but with no luck. Please help :) (ipp2p is up and running) _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

I have two T1s and I'd like to split my SIP traffic over the two. I am looking at this: http://lartc.org/howto/lartc.rpdb.multiple-links.html what bothers me about it is the note "Note that balancing will not be perfect, as it is route based, and routes are cached. This means that routes to often-used sites will always be over the same provider.". If all my traffic goes to the same

hi, i wann to make multigateway routing and i read ur how to on http://lartc.org/howto/lartc.rpdb.multiple-links.html and create some rules which i am sending u, but with this rules i am not able to do multigateway routing on my linux router so plz help me out. thanks the rules are given below IF0=eth0 IF1=eth1 IF2=eth2 IP1=192.168.1.2 IP2=61.246.243.86 P1=192.168.1.1 P2=61.246.243.81

Hello, I started off by reading the Linux Advanced Routing & Traffic Control Howto, then searched a bit around the web. I see many documents discussing these matters with kernel 2.2.x but they are quite old, something around 1998-2000. I have some questions but I might as well start by exposing my setup to clarify things. I have a couple of internet links: a leased line of 256kbit/s and an

Doing routing based on this: http://lartc.org/howto/lartc.rpdb.multiple-links.html Have done it for over a year. Tried a new 2.6.15 kernel. Firewall is based on debian sarge. Most things work ok dnat snat etc. Can simultaneous ssh in to an internal host via both isps with no problems. At the moment the default route is via eth2. root@fonroute:~# ip rule 0: from all lookup local 200:

Hi, I configured a router box to use 2 providers, as described in the HOWTO. (Apendix 1) I want to use both links to reach a single smtp server. As I read in the kptd and in some old messages of this list, doing a SNAT in the postrouting chain comes _after_ the routing desision. So I guess the following lines I''m trying to use are wrong. (See Apendix 1) What can I do to have multiple

Hi. Contents: 1) Introduction 2) 2 Questions * Introduction: I used this HOWTO to use multiple providers. http://lartc.org/howto/lartc.rpdb.multiple-links.html The box is a load balancer, using the Linux Virtual Server. We have a problem with lost connections, and it seems you get issues when you combine this setup with DNAT [1]. The proposed solution [1] is to use these rules to mark

Hello, I have a very strange problem that I can''t seem to be able to figure out. First of all: my network scheme: http://heavyg.safehex.be/network.png I have an agreement with my neighbour that I can use his wireless network to experiment with extra internet uplinks in exchange for some filesharing etc. Now I have set up a wireless router at my place, that connects to his network.

Hi All, I have a linux router, configured with two internet connections and two lan segments. I''ve setup multipath routing as described in http://lartc.org/howto/lartc.rpdb.multiple-links.html My problem (I think) is that somehow the router will randomly choose incorrect routing paths for different hosts, for example: on my workstation (192.168.1.20), I ssh to a server I have on an

Hi list, I''m trying to setup a Linux box with a complicated source routing and could use a hand from you. The box has 4 NICs and lots of VLANs attached. It is a firewall and router in the following scenario: (obs: IP addresses have being changed for security purposes) - eth0 holds the default route (GW: 200.1.0.1, Firewall: 200.1.0.2); - The box is routing and sometimes source

Dear friends - I am trying to understand fda and working with the 2009 book from Springer. I run the scripts directly from a new installed fda library and include sessionInfo() below. This is from the script fdarm-ch09.R - I seem to have got not fda_2.2.8 but 2.2.7 - is that the problem? Where do I get .8 as I just reinstalled?

Hi all, I am wondering if anyone can help me to resolve a problem. I am trying to use tc command in linux to drop udp packets of specific diffserv value.

Hi, Is it possible to create a routing rule that depends on the source host/network, besides the target host/network? E.g. route everything from 192.168.0.x to 10.0.0.1, and route everything from 192.168.1.x to 10.0.0.1. TIA -- Groeten, Joost Kraaijeveld Askesis B.V.
