similar to: linux bridging vlans?

re I would like to do some firewalling and p2p shaping/limiting on one of the vlans in my network and I was thinking of using linux box as transparent bridged firewall/limiter. For this I''m planning to use AMD64 2.2Ghz box with 2 1gbit NIC (Broadcom 5721), that will be bridged. The box must be totally transparent and unseen in the network, as well as it should have much influence on

Hi, there is something I''m not able to understand about HTB statistics. Why the qdisc show show how many packets are overlimits but in the classes there are always 0 packets overlimits or dropped? I try to expain with a simple example. I create a qdisc htb with only a class and then i do a lot of traffic. pc-innocenti:~# tc qdisc add dev eth0 parent root handle 1: htb default 10

Hi, I''m getting this warning/error in /var/log/messages: May 26 18:21:05 mail kernel: HTB: quantum of class 10010 is small. Consider r2q change. Its a big deal? What should I do? Many thanks Oliver -- Oliver Schulze L. <oliver@samera.com.py>

Hi everybody! I''m using an edge bridge box with two ethernet cards to shape traffic in a WAN link. I''m running Debian 3.1 stable with kernel 2.6.8 and iproute from packages. I recompiled the kernel with the following built-in options: [*] 802.1d Ethernet Bridging [*] QoS and/or fair queueing <*> HTB packet scheduler <*> SFQ queue [*] QoS support

Hi, I am configuring some servers in a high availability setup. The servers are connected to two switches with two LAN cards in each server. The two switches are connected directly to each other. The servers are configured to bridge eth0 and eth1 with spanning tree. Usually this makes sure eth1 is disabled, unless something happens to eth0. This way I can have one IP address on each server. Now

Running on Centos 5.6 with KVM... I was wondering if anyone had any luck configuring the NICs where eth0 and eth1 are bonded together with vlan support to a bridge? I noticed some threads show this as a possibility (http://lists.centos.org/pipermail/centos-virt/2009-November/001417.html), but haven't had any luck implementing it. There also seems to be a bug with 5.6

Hi, I was hoping someone on this forums could help me out with a problem I was facing with Xen. When I compiled the kernel for Xen-3.1.3 using "make world"(I know this is an old version but I need to use it for some compatibility issues), the kernel was missing the Xen netloop module. There was no /kernel/drivers/xen/netback/netloop.ko in the newly compiled kernel. I think we would

Hello You must add first: vlan (tagged) to eth2 eth2 interface is not tagged by default and not know vlan-s . It is like a cisco if you have 24 ports in cisco by default all ports are in vlan1. if you want to do trunk (with vlans) you myst add (vlans) to this ports (tagged or untagged) So you can compare that all interfaces in linux by default are in one vlan(but not tagged). (only for

Hello list, I've posted here about this before, but I realise that it may have been assumed that the bridged vlans simply put a switch port in a blocking state and left my question ignored. So to recap. I have two tg3 interfaces named 'in' and 'out' and a bridge named 'br0' My vlan trunk is on the 'in' side of the network, and set as in.2, in.3 ... The

Hello. I''m trying to use vlan in domU, but have something strange: I created bridge on eth0. This interface was configured as trunk with vlan 300, 301. I use this bridge in my domU, and I can see tagged packets when run tcpdump in domU. Also I created interface on domU to work with vlan 300. On this interface I see untagged packets in vlan300. And everything looks fine. But when

Hi *, having built Xen 4.1.0 and running my Dom0 on Slackware 13.1, I''m trying to assign different physical network interfaces to different DomU guests: vif = [ ''bridge=ethX'' ] in the DomU configuration files.

Hello Peter & Jeremy, I've found an ordinary desktop PC (with Phoenix Award BIOS 6.00PG) that won't boot off a USB stick created by livecd-tools-024 with syslinux (tested both versions 3.75 and 3.81). The boot process drops to the "boot:" prompt with an error message: could not find kernel image: linux The same USB stick boots fine on any other computer I could find.
