Default Igmpproxy won't start in 5.5 Current

Hi,

I've just re-updated my CURRENT build and performed a:

Code:
pkg_add -vui
my ports tree is 100% up to date through CVS and I'm using the correct one.


What is odd is that in 5.4 I had a working igmpproxy setup and now it comes up with this error:

Code:
igmpproxy, Version 0.1 beta2, Build 140421 
Copyright 2005 by Johnny Egeland <johnny@rlo.org>
Distributed under the GNU GENERAL PUBLIC LICENSE, Version 2 - check GPL.txt

ERRO: MRT_ADD_VIF; Errno(45): Operation not supported
My build is:

5.5 GENERIC.MP#86 amd64

/var/log/messages show:

Code:
igmpproxy: Note: adding VIF, Ix 10 Fl 0x0 IP 0x01c9c90a tun1, Threshold: 1, Ratelimit: 0
igmpproxy: ERRO: MRT_ADD_VIF; Errno(45): Operation not supported

As well as my other interfaces and vlans.

Could it be that I'm running two tunnel interfaces which is causing igmpproxy to frazzel out?

One of the interfaces is part of OpenVPN and the other is part of L2TP/IPSEC.


Is there a fix/solution for this as currently inter-vlan igmp is not working?


Thanks

I don't know anything about igmpproxy. I assume your question relates to this guidance from the igmpproxy(8) man page:
Code:
       Since igmpproxy only uses IGMP signalling, the daemon is only suited
       for situations where multicast traffic comes from only one neighbouring
       network.     In more advanced cases, 'mrouted' or 'pimd' is probably more
       suited.    The daemon is not designed for cascading, and probably won't
       scale very well.
There has been no change to this port since June of 2013. The underlying system has changed.

I've looked at the port. The error message is produced by mroute-api.c, line #147 (with the OpenBSD port's patch applied):
Code:
    if ( setsockopt( MRouterFD, IPPROTO_IP, MRT_ADD_VIF, 
                     (char *)&VifCtl, sizeof( VifCtl ) ) )
        log( LOG_ERR, errno, "MRT_ADD_VIF" );
See setsockopt(2). For further assistance, you might reach out to the ports' maintainer, Markus Friedl (markus@), directly, or make an informal query on the ports@ mailing list. Either way, be sure to include a dmesg(8) so that no one has to guess which snapshot you happen to be running.

Just to underscore the point, the output of uname(1) is not as descriptive as the output of:

$ sysctl kern.version

...& the output of dmesg(8) is far better.

Thanks for the advice.

I have already attempted to contact markus@ with dmesg output and problem output etc... I think I even tried running igmpproxy in gdb too and sent that along.

I didn't get any response though which is why I came here as perhaps someone would have an idea of how to fix it.

Perhaps @ports is the right place to ask as I'm totally lost

Markus has been busy. If you've already reached out to him, give him several days to respond before posting to ports@.

Hi jggimi,

I actually emailed last week or the week prior?? Can't remember now as I've been immensely busy too

I guess I could give it another week and then see where things are at.

The last thing I want to do is annoy any one! Also since OpenBSD is an OS that needs a lot of experience or development capability and since I have neither on this OS I always feel like I'm treading on thin ice.

If after a week you've received no reply from a $MAINTAINER, then you should feel comfortable reaching out to the list. As long as your problem report is as complete as you can make it, you should not fear posting.

Thanks so much for the advice jggimi

Having gone through the link you sent me, I thought it was better to file a bug report and posted to bugs@

In any case I tried to give as much output and detail as I could.
