Re: [lartc] Virtual Interface
Mike,
Thanks. I will try it..
I have not explained the puspose for this doing this - just to give you an idea I want to create around 200 virtual interfaces and send traffice through all the interfaces simulating traffic comming from different networks. Do youthink this approach will scale to that level?

If all went well there should now be two new virtual ethernet devices,tap0 and dummy0.Hope this information is useful to you,Mike Wright :m)___

Re: [LARTC] Virtual Interface
Thanks Ryan. VLAN will not for for me, I will check ebtables. BTW, I was thinking more on lines of MAC-VLAN. I could not find much information about it. I will really appriciate if someone can provide me some direction one this.

Re: [lartc] Virtual Interface
Hi Roger,
[big snip: lost o.p.]
There are a couple of different approaches you might try. One is to use
uml-utilities' tunctl to create an ethernet tap. Another is to use the
dummy interface. With either method you can bridge, route, configure as
you would a physical device using ifconfig and/or ip.
The following methods work for me. I use Fedora Core 4. Its network
setup methods are in /etc/sysconfig/network-scripts.
cd /etc/sysconfig/network-scripts
ln -s ifup-eth ifup-tap
ln -s ifdown-eth ifdown-tap
echo 'ip link show tap0 | grep tap0 21 /dev/null || tunctl -t tap0
DEVICE=tap0
TYPE=ethernet
ONBOOT=yes
BOOTPROTO=static
MACADDR=5a:5a:5a:5a:5a:5a
NETWORK=192.168.0.0
IPADDR=192.168.0.1
BROADCAST=192.168.0.255
NETMASK=255.255.255.0' ifcfg-tap0
ifup tap0
ln -s ifup-eth0 ifup-dummy
ln -s ifdown-eth ifdown-dummy
echo 'ip link show dummy0 | grep dummy0 21 /dev/null || {
ip link set dummy0 up
ip link set dummy0 arp on
ip link set dummy0 multicast on
}
DEVICE=dummy0
TYPE=ethernet
ONBOOT=yes
BOOTPROTO=static
MACADDR=a4:a5:a5:a5:a5:a5
NETWORK=192.168.0.0
IPADDR=192.168.0.2
BROADCAST=192.168.0.255
NETMASK=255.255.255.0' ifcfg-dummy0
ifup dummy0
If all went well there should now be two new virtual ethernet devices,
tap0 and dummy0.
Hope this information is useful to you,
Mike Wright :m)

You can do this with vlans, but this may not be a suitable solution, as if you want to make them work normaly, you will need to tie this to a vlan capable switch.

RE: [LARTC] virtual interface
Alen, : can i add HTB rule on virtual interface? : example: eth0:0 First, it's not really a virtual interface--it's just a convention from the old days of IP aliasing to have names like eth0:0. The IP exists and is active on an interface, eth0 in your case. The short answer is no. Traffic control occurs just prior to the release of the packet for transmission by the hardware driver. See the KPTD [0]. You can however select packets based on many characteristics, so you may be able to accomplish what you need. You'll use characteristics other than the label eth0:0. Hi guys, I have this problem too. I have two Internet routers connected to the same Ethernet interface (using a hub). And each one obviously needs to be shaped seperately. It seems like a very common and logical scenario and this issue seems like a design problem. Any Ideas on a workaround? Perhaps IMQ can be used somehow (although I hear it has serious stability problems...)?

Re: [LARTC] virtual interface
There is no need to use imq ant everything is easy to do anyway interface name is usefull only to attach qdisc to something and that all you need to clasify packets by source or destination ip antway if you have idea how to use imq there then just use your interface instead. also why it is so obvious that they must be shaped separately, ususly it is much better to shape everything in one einterface Hi guys, I have this problem too.
