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.

The BBC are currently trialling multicasting the Olympics. This requires multicast and IGMP to be available. As far as I can make out, in 2.0.8 at least, all multicast addresses are filtered out and, to my naive eyes, can''t be re-enabled. Please prove me wrong :-) Dirk -- Please Note: Some Quantum Physics Theories Suggest That When the Consumer Is Not Directly Observing This M...

The testsuite that checks for mcast_max_groups functionality will need to wipe the added groups as well. Add helpers to build an IGMP or MLD packets announcing that host is leaving a given group.

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 shorewall / iptables cope with this? Dirk

Hi, Is there an IGMP Snooping implementation in development in the bridge module ? Is the bridge module a good place for this feature ? It is better to add it in the module or in user space ?

Hi All, I have to develop IGMPSnoop application within kernel 2.6. For the same purpose, I would have to Snoop L3 level IGMP packet at L2 level(Bridging level). Can anybody suggests how it can be done. Does Netfilter library support this kind of feature. Thanks In Anticipation Maverick -- ____________________________________...

...tizing traffic upstream of a slow wan link using htb, classic wonder shaper type stuff. I''m using the following command for traffic that does not match any of my defined filters: tc qdisc add dev eth0 root handle 1: htb default 50 It appears that local, non-routable traffic like arps and igmp are being snared by this and end-up queued in the lowest priorty queue. I was surprised that non-IP traffic would be effected by IP traffic control. How do I prevent this local, non-routable traffic from being queued? Since it''s local, I just want it to go at line rate. I know if I remove...

Currently we would still potentially suffer multicast packet loss if there is just either an IGMP or an MLD querier: For the former case, we would possibly drop IPv6 multicast packets, for the latter IPv4 ones. This is because we are currently assuming that if either an IGMP or MLD querier is present that the other one is present, too. This patch makes the behaviour and fix added in "brid...

running Version 3.6.23-14.el6_6 I'm having slow save times with folders names ~something.. ie. /www/~bin/content.txt. doing this via a windows share.. when I save file it has a moment (few seconds) of hesitation.. then saves. When I do /www/bin/content.txt. the file saves instantly. Is there anywhere I can change a setting to fix this? or is this a bug. I've looked in the logs

I have used lokkit to setup iptables ( I have a big script that does this) basically just ports I want with "--port=https:tcp" etc... I wish to allow igmp and add igmp to the lokkit command line? How do I do that?
