Hello i want to know how to configure bonding in kubuntu/ubuntu linux:
3 network cards: 2 Internet + 1 Lan

Thanks in Advance

Hi,

You need to add following package to attach and detach slave interfaces to a bonding device
Enable bond0
Now setup bonding mode for Round-robin policy:
Now open /etc/network/interfaces and modify as follows:
And just restart computer and you are done test the same:

Thanks for the fast answer.


i have another questions:

1. the ip address i have to configure in the gateway of my lan pc's is the bond0 ip address?


2. if i have configured a squid proxy, to take advantage of bonding + transparent proxy should i configure the iptable to route to bond0 device instead of eth0 which is the actual configuration?

i mean:

i have it configured like this:
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128

i need to change to eth0 for bond0??

You need to use bond0 to get benefit of bounding. There was some problem in old kernel. If you are using latest kernel you should be fine with iptables and bond0 configurations/squid.

Thanks for the answer.

Another Question: What should i write in the gateway of the bonding interface?

Put your router IP address that connects to your WAN / LAN / Internet

i have installed and configured squid 2.6.
i made the transparent proxy configuration:
"http_port 8080 transparent"
"always_direct allow all"
and set the route:
"iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 8080"

i put the ip of the lan interface of the server in the gateway of another machine, and the internet does not work until i set the proxy in the browser connection configuration.

then i installed firestarter and enable the sharing internet connection option and the internet works without the proxy configuration in the browser.

the question is:
how do i know if the clients having this server as their gateway are using the squid cache or going straight to the internet??

Thanks in Advance

Hi all

i want to bond several nics together where each nic has an own
internet connection. i. e.:
host 0 has 3 interfaces eth0, eth1, eth2. each of them is connected
to a separate host.
host0:eth0 to host1:eth0
host0:eth1 to host2:eth0
....

each host 1,2 ... acts as a gateway with an internet connection.
the intend is to to bond all internet connections to one fast internet connection.

client --- host0:bond0 --- host0:eth0 --- host1:eth0 ip 168.0.1.1
--- host0:eth1 --- host2:eth1 ip 168.0.2.1
--- host0:eth2 --- host3:eht2 ip 168.0.3.1


How can i configure multiple gateways for the one bond ?
Or how can i specify for each slave interface its own gateway ?

Thanks for any reply.

Is it possible to bond if bond0 is dynamic. I have been trying for a while now with little success

I have tested the NIC's and they should work. I have even loaded XP and they do work using WinGate and InterGate but I don't want XP on my box.
