Hi, today a couple of Hypervisors got restarted due to a power outage. While the systems and the VMs on the are running fine multicast traffic between the guests is no longer working. I generate multicast udp packet using iperf in the guest and check on the host using tcpdump: tcpdump vnet0 => multicast packets are visible tcpdump vlanbr8 => multicast packets are visible tcpdump em1.8

Would it be extremely difficult to do multicast over tinc? How about reliable multicast over tinc? This would be more traffic than multicast dns, but not _necessarily_ a great deal more. It would be for syncing some information among freeipa domain controllers. Would the tinc nodes need to be in all in switch or maybe even hub mode? EthernetOverIP over tinc?

I have a standard 3 interface shorewall setup and I want to receive multicast stuff from ''net'' -> ''loc''. This requires me, first, to do an IGMP join which involves 192.168.1.x -> 224.0.0.x being NATed out as the ''net'' interface''s IP address. Obviously replies have to be NATed back to ''loc'' addresses. Can

Hi all, We want linux (ubuntu) with 2.6 kernel to act as multicast router and to pass multicast packets between different subnets. And linux machine as router has two network cards having two different subnets assigned onto. We first worked "sysctl -w net.ipv4.ip_forward=1" line on linux shell that made linux to work as unicast router. (like host, the multicast packets were discarded at

Hello All, I'm trying to figure out why xen-utils-common 3.2 doesn't suport bridging on multiple interfaces. I've been digging around /etc/xen/scripts/network-bridges. And modified it so that during boot, when executed the script writes into /tmp/netbr file, but I commented out code that actually creates bridges. I discovered that this script is called three times during boot, I

I am trying to set up my Shorewall box to forward multicast packets to my local net. I do have some problems with mrouted (see below), but I can join and add routes using smcroute. Multicast works when shorewall is disabled. I got a lot of help from the following. http://lists.shorewall.net/pipermail/shorewall-users/2005-January/016674.html I cannot get the multicast packets to pass the fw when

I need to send multicast traffic through a GRE tunnel between two Linux routers. The tunnel works for normal IP packets, but I can''t see how to make it work for multicast. Here''s the setup: 10.10.10.0/24 LAN-B--------------RtrB-------------RtrC--------------LAN-C 192.168.2.0/24 192.168.1.0/24 RtrB interfaces: eth0

Hi, I''ve setup a box with xen.

We have had an interesting issue with Market Data and Network Interface failures in the past with ipmp (or even VCS multinicA).. Multicast groups can not span multiple interfaces and in our environment when we have a network failure the interface is failed over however the multicast group does not. The only way to recreate the multicast group is to restart the application with the active network

Dear I need create second bridge xenbr1 for separate traffic between my virtual machine , I following this step but show message that Link veth0 is missing, how I can create veth0 ? When I run script for create xenbr1 ./network-bridge netdev=eth1 bridge=xenbr1 start Shwo this message Link veth0 is missing. This may be because you have reached the limit of the number of interfaces that the

Hello. I''m new to this list. I''m trying to set up multicast routing between two networks: Internet ^ | Windows box | | UserModeLinux A <-----> Colinux Router <-----> UserModeLinux B

Hi, my ISP is streaming some local concert using UDP multicasting. I followed the instructions on the site which described how to set VLC in order to view the stream, but it didn''t work. I am behind a Linux router/firewall doing NAT. Using google, I quickly found out that the netfilter/conntrack code doesn''t support NATing multicast traffic. I thought about bridging the internet

The documentation is very clear that multicast over tinc does not work in router mode. Why?

Hi, all! Can I enable multicasting via shorewall? I have router with Gentoo Linux (one interface to ISP, one with alises - to local network). Shorewall work perfect! But now I need setup Quagga (zebra) for dynamic routing between one more router via another provider. All routers daemons (zebra, ripd, ospf) used multicasting. In my configuration already enabled allowBcast and etc.

Hi all Can someone explain me this: ifcfg-eth0-range1: ONBOOT="yes" IPADDR_START="192.168.1.48" IPADDR_END="192.168.1.55" CLONENUM_START="1" Why Bcast is 192.168.1.51 and why Mask is 255.255.255.252 ?

Hi. I'm proposing a wireless distribution system in infraestructure mode for a valley with no cables and distant houses, respect to Asterisk, I can get a company I work with to provide me with E1 and use LCR to get 4 different telcos based on prefix. I've been reading a very interesting paper about voip on wireless, i recommend it really

Hello, Can anyone tell me why the maximum number of members in a multicast group is set at 20? Are there issues with increasing this number? Any information would be greatly appreciated. Thanks, Steve Clark -- "They that give up essential liberty to obtain temporary safety, deserve neither liberty nor safety." (Ben Franklin) "The course of history shows that as a

Hi, Here are two, small feature changes I would like to submit to increase the usefulness of the multicast snooping of the bridge code. The first patch is an unaltered one I had submitted before, but since it got no feedback I'm resubmitting it here for net-next. With the recently added patch to disable snooping if there is no querier (b00589af + 248ba8ec05 + 8d50af4fb), it should be a safe
