Multicast issue: FOG specifying wrong interface when starting udp-sender

[nengelhardt]

Hello. I’ve noticed an issue where FOG is not using the correct interface when starting udp-sender, which results in it quitting right away and not running the multicast task. My interface name, as specified in fog_udpcast_interface is “enp4s0” but FOG appears to keep trying to use “eth0”, as shown in the log below

What version of FOG?

[nengelhardt]

I forget. I’m not at work right now. Whatever the latest git version was at about 1800 UTC-6 yesterday.

Seeing as you’re on trunk, the FOG_MULTICAST_INTERFACE setting you described that you set is not what is used. Seeing as Multicast is ultimately dependent upon the master node of a group, it only seemed appropriate to move the interface definitions to the node’s panel. Check your nodes and ensure they’re setup to point at the correct interface as well as anywhere else you think needs this definition specified. You may need to restart the fogmulitcastmanager service.

Where else is there besides that setting in the web interface that you just said is not used anymore, and in .fogsettings? Both of those are right.

The interface field in the .fogsettings file is only used when the installer is ran.

@Wayne-Workman I checked that, but I’ll check @tom-elliott’s suggestion next time I’m working with it.
