Multicast not starting
-
Back with the same problem.
I started one one my bi-annual labs redeployment.
The multicast doesn’t start. All computers are ready for the image:

The tasks are created:

First, I removed the task, rebooted but it doesn’t help. All computers remain stuck at the same window.
The solution was, as the last time, reinstall fog. I started the installer (it was the same version, 1.4.4).
When the install (or let’s call it upgrade) was done, I created the tasks again, rebooted the computers and this time it worked like a charm.

Thanks for your help.
P.S.
OS: Ubuntu 16.04 (all updates installed, no fancy settings, the default OS).
FOG: latest version, 1.4.4 -
I’m back with some more info.
It looks like the problem was that udp-sender wasn’t started by the multicast manager service. If I restart the service, the udp-sender starts. I reboot the workstations and this time it starts deploying. -
@andreiv Please go through these two articles:

I will. Thank you. I have 3 more deployments coming up. I’ll get back here if the issue repeats and I find the solution.

Went through debug but I still cannot figure out why is this happening.
First, I found that the network interface used by udp-sender was wrong. Corrected that in the config file. Tested again, but the issue repeats exactly as the first time.
I checked, the MulticastManager service was running, status OK. udp-sender was started, network interface ok, number of clients ok. All seems perfect.
But after each server restart, multicast doesn’t start.
If I reinstall fog, all works OK.
Very strange. -

It’s corrected in the FOG Web GUI, not a config file. The first article I linked below shows how.

I also checked the udp-sender command line from the terminal and the interface was the correct one.
I’ll collect more data at the next deploy (in the next few days) and get back here with it. -
