Can not create deployment tasks

[Tom Elliott]

Is there a specific reason to use single system multicast?

I still want to help fix it, but as you said you have multiple nodes, my suspicion is that’s why you’re seeing the waiting screen, it’s not looking at the correct node to get the image from, or hear the udp-cast message.

I’ll fiddle with it tomorrow to see what else I can wiggle from it to see about multicast to verify if it’s looking good or not through a tcpdump and all.

I uploaded an image and then tried to download the same image of my laptop and that apparently has borked it so now in repair mode on that.

When I create a multicast deployment task and the client is at the screen of “Starting to restore image” should I see a udp-sender program running in my processes? I’m running down the troubleshooting page I found on the wiki, and it seems to work. [url]http://www.fogproject.org/wiki/index.php/Troubleshooting_a_multicast[/url]

I can’t get the manual part at the bottom to work to force imaging (gunzip keeps ignoring cause it’s a directory) but I can do the first tests with 1 and 2 clients for sending the multicast.log file fine.

Looks like the FOGMulticastManager service didn’t start up at all, from default install or even by reboot on, CentOS 6.5 at least.

/etc/init.d/FOGMulticastManager status
FOGMulticastManager is stopped
/etc/init.d/FOGMulticastManager start
Starting FOGMulticastManager: [ OK ]

Found the service and started it, multicast imaging is now working!

EDIT: For the record, in case anyone else has this issue and comes across this thread, you WILL get a process for the UDP being sent out. You should get two, and one’s gonna be several lines long.

If your only result back is the “grep udp” then you’re not working.

I ran into a lot of the problems. Since it’s only an imaging server I literally opened up TCP/UPD 0:65535 ports and disabled Selinux. Everything works great now.
