Topic: Galleon? Multicast issue?

[jdc0730]

Is anyone out there successfully running Galleon on their SME server?  I am attempting to do so, but am getting errors at start up:

I have added entries to the configuration db for all the required ports and checked that they are unused before Galleon starts.  All looks good.  If anyone as had any luck with the app, I would appreciate some insight.

Thanks,

With my limited networking knowledge.  It appears that a multicast call is being initiated with is showing up in the iptables local.  The call is to 224.0.0.251 UDP 5353 (Rendezvous port).  When I try to ping the address, I get the same operation not permitted error.  Can anyone provide any insight on whether this should or shouldn't work with SME?

So it seems like I am talking to myself.  

Multicast was the issue.  I saw that SME is blocking all multicast traffic by default.  I create a custom version of /etc/e-smith/templates/etc/rc.d/init.d/masq/40DenyMulticast and simply blanked the lines out.  That allowed the application to run fine.  So a couple of questions for the networking folks out there:

Is there a problem enabling multicasting?
Is there a better way to enable it?  
Some I just enable the one address being called (is this possible and if so, how?)

Thanks!

Thank you! This same issue has been haunting mt_daapd users. I don't know about the downsides, but at least now things work.
