Multicast won't start

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

@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’?

Wayne Workman · Aug 11, 2016, 1:04 PM

@Pascal-Gazaille It’s supposed to be marked as done, at least. There’s been work in this area, I’m going to defer to @Tom-Elliott on that question.

Tom Elliott · Aug 11, 2016, 1:05 PM

We’re at 1.3.0-RC-8, which I know addresses issues on multicast closing. This should be fixed now, so YES it should. NO need to defer, please update and see if all is well.

Towndrunk · Aug 11, 2016, 7:47 AM

@Wayne-Workman I went in and followed the steps listed below. I’m assuming that these are the steps that you were asking me to do?

mysql> DELETE FROM `multicastSessions` WHERE 1;
Query OK, 15 rows affected (0.00 sec)

mysql> DELETE FROM `multicastSessionsAssoc` WHERE 1;
Query OK, 2 rows affected (0.00 sec)

mysql> DELETE FROM `tasks` WHERE `taskTypeID` = 8;
Query OK, 42 rows affected (0.01 sec)

I then restarted the service, and tested again. I got the same results.

@Towndrunk Can you repeat the steps to clean the DB, then update to RC-8 (installing RC-8 will restart fog multicast manager as part of the upgrade), then try again?

Towndrunk · Aug 11, 2016, 7:57 AM

@Wayne-Workman I can do that. I am already running RC-8 though. I ran the upgrade this morning before doing the steps to clean the DB. If you want me to, I can repeat the process now.

@Towndrunk No, don’t bother then.

Now, once the Multisession is started the first computer will join and sit on the same screen as it always has, but now the second computer will not connect. It does all of the checks, but then Attempts to check in and fails. . .

Is there a limit on how long you have to join the Multicast? I just tried another test and set it up for timeout of 10 minutes. I was able to get the first one added, however once I went to the second one it was not able to find the Session I created.

The odd thing is that if I send an image to any of these the individually I have no issues at all. I just assumed that the Multicast would be quicker if we were doing a group all at once. If I have to, I can just go back to doing them individually.

Pascal Gazaille · Aug 11, 2016, 3:16 PM

@Wayne-Workman @Tom-Elliott Just wanted to thank you guys, great support for a great product!

BedCruncher · Aug 11, 2016, 4:05 PM

@Towndrunk
There is a setting under the header Multicast Settings that is called FOG_UDPCAST_MAXWAIT you might look there to see if that is where you set the 10 minute timeout.

Wayne Workman · Aug 11, 2016, 4:07 PM

@Towndrunk Try to multicast to a group with just one host in it. Use groups to create the multicast task. See what happens. At this point, I just want to see if multicast is working at all.

Towndrunk · Aug 11, 2016, 5:45 PM

@Wayne-Workman I made a group called Multicast and added one computer to that group. I sent a multicast to that computer, and powered it on. It comes to the same screen as it has in the past, and sits there. It doesn’t appear to be doing anything, and I’m not sure how to interpret what the logs say it is doing. . . It just continues to post the “Task (4) Multi-Cast Task is already running PID 28433”
