Ubuntu 14.04 LTS, Fog 1.2 multicast not working

[chall]

New to Fog, followed walkthrough to set up a single fog 1.2 server. No prob PXE booting and registering a WIn7 client and and unicast is working fine to capture and deploy an image to from the client. Tested using same switch we have been using for Ghost multicasting (single subnet on same switch).

Unfortunately when attempting to multicast, the clients connect and show up on the server they just never start transferring. When going through the multicast troubleshooting guide, getting a bit lost and not able to start and stop the Mulicast service or detect the process.

Been stuck a few days would love to get this back on track.

@chall If things get stuck with multicast you usually need to “cleanup” by hand. Delete all the active tasks in the web gui (ALL!). Kill all udp-sender processes and best if you restart FOGMulticastManager:

sudo service FOGMulticastManager stop
sudo killall -9 udp-sender
sudo service FOGMulticastManager start

Then try again.

Followed your suggestion - see below:

administrator@fogtest:~$ sudo service FOGMulticastManager stop
[sudo] password for administrator:

• Stopping FOG Computer Imaging Solution: FOGMulticastManager start-stop-daemon: warning: failed to kill 1383: No such process
  [ OK ]
  administrator@fogtest:~$ sudo killall -9 udp-sender
  udp-sender: no process found
  administrator@fogtest:~$ sudo service FOGMulticastManager start
• Starting FOG Computer Imaging Solution: FOGMulticastManager [ OK ]

---------------------------------------------end log----------------

Attempted to push image to 2 clients via multicast. Same behavior, clients never start transferring. They stay on the Starting to restore image (-). Active tasks on the server shows them but the transfer never starts.

I “think” we figured it out.

Went into FOG Settings > FOG System Settings > Multicast Settings > FOG_UDPCAST_INTERFACE change it to the interface listed which was eth0 to what was listed in ifconfig which is em1.

We then restarted the Multicast service:

sudo service FOGMulticastManager stop
sudo service FOGMulticastManager start

Thanks,
Chris

@chall Good you found this and thanks for letting us know. Hope this might help others as well.

I am just wondering which interface you specified when installing??

FOG 1.2.0 doesn’t change the DB’s interface settings from the default eth0, even if you specify something different during installation. FOG Trunk does though.
