similar to: Loadbalancing and failover using TC and Iptables

Hi, A friend of mine has 2 lines of 512kbps terminated in two Linux boxes. He now want to remove those 2 boxes and have some device which will loadbalance the two ISPs and also have a failover arrangement. But he has agreed to give me a chance to do it on Linux for my own satisfication. Is this easy to do with lartc? How do I go about it exactly? I have very less time to do it since his

Hi all, After posting some emails here and googling in the net. I have now a little clarity where and how to start bandwidth Management. Hope I can still be guided though. My understanding is I will be needing these modules and linux utilities. I hope someone can confirm. 1. I need to use iptables/ebtables for packet marking. 2. I can use tc for packet shaping. 3. I can use bwm_ng for

Hello everybody I’m french and ‘im a network administrator. It the firs time I write on this mailing list ..

Hi An earlier post sited the following links as helpful for setting up multiple external IPs: http://selab.edu.ms/twiki/bin/view/Networking/MultihomedLinuxNetworking http://selab.edu.ms/twiki/bin/view/Networking/RoutesKeeperProject I''ve tried repeatedly to follow these links, but they seem to be dead. Does anyone have this information that they could share, or know where else I can

Hello, I have finished setting up the load balancer with IPROUTE ... also patch the kernel to support DGD and now it''s working fine with the valuable guide at LARTC website, Julian Anastasov, and the kind people in this mailing list. Now I would like to launch a web server and a ftp server to the public but I''m stuck into a problem and really need your help. Currently internal

I''ve managed to get myself confused with what is probably quite simple so if there''s any definitive documentation then please give me pointers. I''ve read and tried the nano.txt document, that''s what I''ve based my current setup on and it isn''t working at the moment. I have two external links, a DSL link on eth1 and a cable link on eth2.

hi all. First of all, sorry for my (bad) english. I Want to balance the traffic in a local network over two ADSL. I wanna send http traffic trough ADSL line number 1. And the other traffic by the default ASSL (number 2) Can you help me ? thx. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO:

I have a very simple setup exactly as described in the HOWTO section " 4.2. Routing for multiple uplinks/providers". One is cable (eth1: dhcp) and the other is PPPoE (ppp0). I used the following commands to configure the routing once all of my interfaces are up and i have configured SNATing for them: ip route add 66.11.173.0/24 dev ppp0 src 66.11.173.224 table 11 ip route add default

Hi guys, Can you take a look at this? :) +-----------+ | | eth1-|- | | -|-eth0---LAN--- | | eth2-|- | | | +-----------+ - eth0 is connected to the LAN having the IP=LAN_IP eth1 is connected to the first ISP having IP=ISP_IP_1 and GW=ISP_GW_1 eth2 is connected to the second ISP having IP=ISP_IP_2 and GW=ISP_GW_2 I need

>Theory is.. You can only shape outbound traffic. Inbound is via tcp windowshaping etc.. In theory yes, but it is shaping inbound transfers to my server. >> iptables -t mangle -A MYSHAPER-OUT -p tcp --sport 65437 -j MARK --set-mark 20 >> iptables -t mangle -A MYSHAPER-OUT -p tcp --sport 50000:51000 -j MARK --set-mark 20 >> iptables -t mangle -A MYSHAPER-OUT -m mark --mark 0

Hi, I''ve setup a gateway using multiple default gateways and netfilter MASQUERADE to load balance traffic between two DSL interfaces and one dedicated link, and when I try to download something big, or when I''m using MSN (both in clients under this gateway), sometimes, or most times, after a while the connection timeouts. The connection doesn''t seem to change its

Hello everyone, First of all, sorry for my poor english. I''ve been working with this for a few weeks and I''m getting sick... I''m trying to control the bandwith in my network using the following script. The machine where the script is running makes NAT, eth0 is connected to the router and eth1 is connected to the Lan. When I run the script it doesn''t appear any

Well it appears i have no clue what im doing. I thought i had the below script working to shape outbound ftp traffic....however, it is shaping inbound traffic too. I have NO clue why. Please comment if anyone has any ideas why this doesnt work. I want to shape only outbound ftp traffic and not inbound or lan traffic. #!/bin/bash #shaping passive and active outbound ftp traffic on an

Will the following rules work to mark and shape OUTBOUND ftp speed (passive ftp ports 50000-60000) on my linux server?

I thought that the below email would be of interest to LARTC readers. I wasted quite a bit of time tracking down this "feature" (bug?). Any comments that shed light on this would be appreciated. In short, "tc filter" + htb + bridging works only with ip_forward off. Andrew Athan ----------------------------------------------------------------------- All: It seems that

I am trying to mark outbound passive ftp traffic with iptables and shape it to 35KBytes. I am using the following script on the computer that runs the ftp server. It is not working correctly, it seems to limit ALL traffic. Cant file share or anything. Anyone might know what is wrong? It seems that I might need to add a ''lan limit'' so all traffic that is not marked still
