Multicast won't start

Wayne Workman · Aug 9, 2016, 4:43 PM

@Pascal-Gazaille Look at this setting:
Web Interface -> FOG Configuration -> FOG Settings -> Multicast Settings -> FOG_UDPCAST_MAXWAIT

What’s it set to? FYI this is the amount of time in minutes that FOS (fog operating system) will wait for all members of the session to join before leaving unjoined ones behind and going ahead with the multicast. This wait-time is used for every partition processed. I recommend 4 minutes. Mess with that, see if you get different results.

Pascal Gazaille · Aug 9, 2016, 5:38 PM

@Wayne-Workman Hi, I’ve changed the setting fog_udpcast_maxwait to 4, tried to multicast 4 laptops and nothing after 30 min.

Wayne Workman · Aug 9, 2016, 11:18 PM

@Pascal-Gazaille Can you clear the DB of non-essential multicast data, and then restart the FOGMulticastManager, and try again? Instructions in the link below.

@Wayne-Workman
This just occured to me, but it seems exactly like the problem that I was having before with the custom rules that I had in my server. This is something that you had suggested that I do and it very well could solve the issue that is happening here…

@BedCruncher But that thread was never resolved, it appears. Turning off the firewall completely - didn’t help you, so it’s not firewall related. Have you tried the MySQL commands and restarted the multicast service yet?

Towndrunk · Aug 10, 2016, 8:09 PM

I’m going to continue to watch this thread because I’m having the exact same issue. I have tried all of the same steps listed in this thread with no change.

Wayne Workman · Aug 10, 2016, 8:10 PM

@Towndrunk Problems are often specific to people. With multicast there’s not “an answer”. We need your details if you need our help.

Towndrunk · Aug 10, 2016, 8:11 PM

@Wayne-Workman I wasn’t sure if I should start a new thread, or post in this one. I didn’t want to have to many issues going on in one thread.

Towndrunk · Aug 10, 2016, 2:35 PM

I have went to Image Management> Multicast Image> and created a Multicast with the information I wanted. I only used two computers as a test, but it failed. I also created a group and added the computers that I wanted to multicast from there, however I get the same indication that Pascal received. It stops on the screen he indicated in his screenshot.

I have restarted the service with no changes. Every time I go and look at the tasks, it shows that the task is in progress even though nothing is happening.

When I look at the logs, it looks like things worked as they should from what I can tell. Please see the attached.

It wouldn’t let me attached the .txt file, so I’ll post the log here.

@Towndrunk said in Multicast won't start:

10.15.31.20

What does that address belong to?

Towndrunk · Aug 11, 2016, 12:11 PM

@Wayne-Workman that is the IP address of the FOG Server.

Wayne Workman · Aug 11, 2016, 6:15 AM

@Towndrunk Well, that’s where it’s trying to send the multicast data to, and that will never, ever work.

Go here:
Web Interface -> FOG Configuration -> FOG Settings -> Multicast Settings -> FOG_MULTICAST_ADDRESS

And set that to 0 then restart the FOGMulticastManager and try again.

Towndrunk · Aug 11, 2016, 12:22 PM

@Wayne-Workman I believe that is where it was by default, and it wasn’t working. A co-worker made the change and it still wasn’t working, but he never put it back. I’ll put it back now and try again as soon as the update is done.

Towndrunk · Aug 11, 2016, 12:47 PM

I went in to Image Management> Multicast Image and created a multicast with the following settings. I added one to the multicast and it was found and sat at the same screen, then added the second and it did the same. This is the same indication I have got in the past, however the log says that it is running.

Session: multi
Client Count: 2
Timeout (minutes): 4
Select Image: The Image

Wayne Workman · Aug 11, 2016, 12:49 PM

@Towndrunk The multicast address is now completely missing from the command, did you set it to 0 or blank?

Tom Elliott · Aug 11, 2016, 12:50 PM

@Wayne-Workman Multicast address on the sender will only display IF the multicast address in the global settings is defined.

Towndrunk · Aug 11, 2016, 1:00 PM

@Wayne-Workman I set it to 0

FOG_UDPCAST_INTERFACE: eth0
FOG_UDPCAST_STARTINGPORT: 64148
FOG_MULTICAST_MAX_SESSIONS: 64
FOG_UDPCAST_MAXWAIT : 4
FOG_MULTICAST_ADDRESS: 0
FOG_MULTICAST_PORT_OVERRIDE: 0
FOG_MULTICAST_DUPLEX : FULL_DUPLEX

Pascal Gazaille · Aug 11, 2016, 12:57 PM

@Wayne-Workman Hey sorry for the delay, I did what you wanted and tried to multicast 4 laptops this morning, it seems to work!

I’m gonna tried with more computer later today!

Wayne Workman · Aug 11, 2016, 1:00 PM

@Towndrunk Can you please try the below steps that I posted for the other guy now?

Pascal Gazaille · Aug 11, 2016, 1:03 PM

@Wayne-Workman Once the multicast job is done, is it supposed to disapear from the DB ‘multicastSessions’?
