#12 Prevent internal IPs from broadcast attempt?

Frank Seidel — Mon, 18 Jun 2018 06:34:29 -0000

Hi, i have the very same problem/question.
Constantly getting those messages filling up my log from not related clients on my lan.
Is there any way to silence this out or tell igmpproxy to ignore those hosts?

#23 Fails to start with Unknown token of my interface error

neocortex — Thu, 28 Jan 2016 11:13:58 -0000

Sorry, my config was wrong (interface position was confused with its role).

Fails to start with Unknown token of my interface error

neocortex — Thu, 28 Jan 2016 08:30:11 -0000

I use Gentoo Linux. It seems that igmpproxy doesn't like my interface. The error is following:
[i]Unknown token 'enp2s0' in configfile
Unable to load config file...[/i]
Interface 'enp2s0' is set as upstream in igmpproxy.conf. Does it support Predictable Network Interface Names?

[PATCH] fails to build with musl libc due to use of non-standard unsigned

Natanael Copa — Mon, 03 Mar 2014 12:23:06 -0000

The use of the non-standard u_char, u_short and u_int types makes build fail on musl libc, which is kinda strict when it comes to standards.

Error message:

igmpproxy not working on FreeBSD dot-separated interfaces

Serzh — Mon, 23 Dec 2013 07:04:31 -0000

for example if I create interface "msk0.2" igmpproxy fail to start on it, but if I create "vlan2" it works fine.

Support multiple multicast sources

Ambroz Bizjak — Fri, 03 Feb 2012 01:34:49 -0000

If a multicast packet comes in on the upstream interface to a group address, but from a different IP source than previously seen, igmpproxy will forget about the old source, and the corresponding multicast route will time out shortly - even if the multicast stream from the original source is never interrupted.

I haven't investigated what in particular the suspicious packet is; it did however originate from the multicast router.

The submitted patch resolves the issue by adding support for multiple source IPs for any given group. Instead of keeping a single source address, MAX_ORIGINS addresses are kept. If we run out of source address slots, the least recently used one will be reused.

not starting without error message

Michael Müller — Tue, 31 May 2011 06:11:03 -0000

When trying to start igmpproxy I only get

ERRO multicast IP forwarding not enabled

Even I use the -d or -vvv options it won\'t tell me more. Any idea how I can figure out what the exact problen is?

Daemon start fails if there are more than 32 vif's

Anonymous — Wed, 15 Sep 2010 05:32:00 -0000

We have an router with many aliases, along 200 ip aliases on more than 10 ifaces.

Daemon crashed on start, where try to enum all VIFs, and open socket for each one.

At the start i have limit of 32 VIFs hardcoded in /var/tmp/portage/net-misc/igmpproxy-0.1/work/igmpproxy-0.1/src/igmpproxy.h
#define MAX_MC_VIFS 32

I was changed this to 256, and change define in /usr/include/linux/mroute.h
#define MAXVIFS to 256 too.

There is the config file:
quickleave
phyint vlan17 upstream
altnet 193.111.x.x/24
phyint vlan11 downstream
phyint eth2 disabled

Starting daemon
igmpproxy -d -vv /etc/igmpproxy.conf

and having...

I have checked some Linux limit such as ulimit, and sysctl variables. They look fine, but i have no ideas what wrong.

igmp snooping does not work after igmpproxy

Anonymous — Sun, 05 Sep 2010 15:57:06 -0000

I run igmpproxy on freebsd8.0 router, then, via cisco 2950 switch, video stream is requested by client as udp://@238.0.0.9:1234 (for example).
Cisco say about correct adding clent port to the multicast group, but broadcast this stream to all ports. Same situation with d-link switch with igmp snooping.
When I run VLC as source of video stream internally in my lan and igmpproxy play role only of igmp querier, stream not go to all port, but go only to client as must with igmp snooping.
