Hi Admin
I am currently working on latest mcproxy (downloaded from https://github.com/mcproxy/mcproxy )
Please help me with the following queries
1. Does this mcproxy support IGMPv3 ? (Source specific multicast ). Please help me in understanding to what extent mcproxy supports IGMPv3 (source specific multicast ) and limitations if any .
2. I see the mcproxy source code is written in CPP . Is the code available in C programming language ?.
Please help me with the following queries
Thanks

here is an example of how to configure Mcproxy:
https://github.com/mcproxy/mcproxy/blob/master/mcproxy/mcproxy.conf
In detail you have to set the group management protocol the proxy shall use ("IGMPv3" for IPv4 or "MLDv2" for IPv6)
and you have to configure upstream interface and downstream interfaces.
Your config file could like like this:
protocol IGMPv3;
pinstance myProxy: eth0 ==> eth1 eth2;

2. Make
But my requirement is to compile for ARM . Could you please help me with the Makefile , or the how to generate ARM compatible makefile from qmake .

there already is support for mcproxy in OpenWRT [1], so you should be able to install it via opkg or lucy.
If you want to build a custom version of mcproxy for your specific OpenWRT platform, you have to use the OpenWRT SDK [2]. I'm quite certain, that simply cross compiling mcproxy for ARM will work with OpenWRT. OpenWRT runs on many different ARM-based routers, the SDK provides a toolchain to build the base system and required packages.
[1]: https://github.com/openwrt-routing/packages/tree/master/mcproxy
[2]: https://wiki.openwrt.org/doc/howto/obtain.firmware.sdk
Hope this gets you started, best,
Sebastian (another one :)

Hi Sebastian
Thanks a lot for your valuable reply .
I have configured mcproxy in the following way and run the mcproxy binary as shown below :
root@OpenWrt:~# cat /etc/mcproxy.conf
protocol IGMPv3;
pinstance myproxy: eth0 ==> eth2.1;
root@OpenWrt:~# /usr/local/bin/mcproxy -dsvv -f /etc/mcproxy.conf
ERROR: failed to parse line 2 unknown token TT_DOT with value in this context
failed to parse config file
But I get the above error marked in yellow, when I configure eth0 as upstream and eth2.1 as downstream interfaces. I think it’s a parsing error in mcproxy.conf but the syntax I followed seems correct.
Could you please help me resolve this issue.
Regards
Siva Prasad

quotes around eth2.1 should solve the problem.
Like this:
protocol IGMPv3;
pinstance myproxy: eth0 ==> "eth2.1";

Hi Sebestian
Thanks a lot for the reply. Yes, it is working now.
I have one more query.
When I use protocol as IGMPv3, and connect two downstream interfaces ,(one host using IGMPv2 and the other IGMPv3),
root@OpenWrt:~# cat /etc/mcproxy.conf
protocol IGMPv3;
pinstance myproxy: “eth0” ==> “eth2.1” “eth2.2”;
Here host connected to eth2.1 sends IGMPv2 packets, host connect to eth2.2 sends IGMPV3 packets. Does mcproxy forward to both the hosts ?
Please help me in this issue.

Siva Prasad

Hi Siva,
Sebastian Woelke
yes, Mcproxy can interoperate with the older version IGMPv2.
I hope this helps.

Hi Sebastian
Following is the issue I am facing while using mcproxy.
I have configured upstream interface as “eth0” and downstream interface as “eth2.1” as seen below.
root@router0D0E0F:~# cat /etc/mcproxy.conf
protocol IGMPv3;
pinstance myproxy:"eth0" ==> "eth2.1" ;
Traffic is sent from eth0 interface and received on eth2.1 interface as expected.
Issue:
Now, I changed upstream interface to eth2.1 and downstream to eth0 like below.
root@router0D0E0F:~# cat /etc/mcproxy.conf
protocol IGMPv3;
pinstance myproxy:"eth2.1" ==> "eth0" ;
In this case, if Traffic is still sent from eth0 interface, it is received on eth2.1 interface which should not be case.
I think streaming should happen when traffic is sent from eth2.1 and received on eth0 ONLY.
Please correct me if my understanding is wrong. Please provide your inputs on this behavior.
Regards
Siva Prasad

Hi Siva,
Sebastian Woelke
I'm not sure if I get your issue, but I try to clarify the relation between upstream and downstream.
The configuration looks like this: upstream ==> downstream
And data received on a downstream is always (unconditionally) forwarded to the upstream.
Data received on an upstream is only forwarded to a downstream if hosts in the subnet of the downstream have subscribed the respective group.
Does this help you?
Regards,
Sebastian
