No udp-sender?

Where do FOGMulticastManager service gets my external IP from?

This is done by calling http://ipinfo.io/ip to get the external IP. Tom added that a while ago, I think it’s used to be able to connect FOG servers that run behind gateways. It’s not particularly for the Multicast service but all FOG services use this interface enumeration. We removed/disabled that part in the latest development version weeks ago as it’s a special use case.

Re-reading most of the topic and especially your initial post I don’t notice much of an issue here. The only statement I see is “I cannot get multitask working”. What exactly does not work? What are your steps to schedule a multicast task? The usual way is create a group, add hosts and schedule a multicast task for this group. I am fairly sure this is working in 1.5.5 as I have tested this not long ago. But there are other ways of multicasting in FOG. Maybe one of the others is not working. Please tell us exactly what you are trying to do.

Hi @Sebastian-Roth, it’s been a “long” time that I’ve been using FOG, it’s not new for me, and it was working.
The issue that I notice is that of FOGMulticastManager not loading ant udp-sender service.
I tried creating a Multicast task from

1. Group
2. Named
3. To a single workstation.
   And I can see that task are created but, in the clients I see
   Attempting to check in… failed
   Invalid Multicast Session (In line for .)

In MYSQL I see

1. In multicastSessionsAssoc table there is one record per client
2. In tasks table there is one record per client
3. In multicastSessions table there is no record

So, my question is, should it be one record in multicastSessions table?

If I do ps aux | grep udp Should I find any udp-sender proccess?

Thanks

Can we get a clear screen shot of this error taken with a mobile phone (unless the entire bit of text on the screen is “Invalid Multicast Session (In line for .)” then it adds no value)? Does it show you the kernel parameters on the error screen?

The context of the error message sometimes is just as important as the actual error itself.

Just to be sure when you go to schedule a multicast deployment, you do have hosts listed in the “Hosts in task” list?

@Sebastian-Roth Its been a while since I worked with Multicasting images, but I just scheduled one and it didn’t ask me for a session name when I submitted the task. Looking at the “Task Name” column the session name appears to be “Multi-Cast Task” Is this expected? (FWIW I’m still running FOG 1.5.4 in production)

Hi @george1421, there they go

[Sebastian Roth]

@URfog Thanks for the details! I’ll have a closer look later on today or tomorrow.

Got me there. I think I never ever used multicast that way. Back at my old working place where we heavily used multicast we’d always schedule it via groups. I’ll check that out as well.

Hi all ( @Sebastian-Roth, @george1421), you can leave this problem, I reinstalled the OS and FOG, and with only one machine and one image in my new FOG it worked, I reused my DB backup and it retruned to fail, so the error was in the DB. I have recreated it and now it’s working.

Thank you so much for your efforts.

[Sebastian Roth]

@URfog Oh wow, didn’t expect that! Thanks heaps for letting us know! Great that you figured this out.

@URfog

What exactly did you end up doing to fix this? I am experiencing the exact same issue with my installation.

I"m running Debian 9.9
FOG 1.5.5

Thanks!

Cheers!

@Joe-Gill See what @URfog said:

Possibly you are in the same situation. Not sure if we can figure out what exactly is wrong in the DB. If I’d have heaps more time I’d suggest you send me a dump of your database and I’d try to replicate the issue and find a fix. But unfortunately I can’t afford the time.

Re-creating the whole DB is probably not an option for you, right?

Maybe start by cleaning up your DB: https://wiki.fogproject.org/wiki/index.php/Troubleshoot_MySQL#Database_Maintenance_Commands

@Sebastian-Roth

Yeah I would rather not re-build my DB from scratch if at all possible. I have fewer hosts now than when I started with FOG but it’s still a large number. I am in the process of setting up another FOG server to do a fresh install and go from there. I do need to clean some things up in there so it may be the time to do this. I did run through the Troubleshoot MySQL Database Maintenance Commands and didn’t get real far with it. I"ll look at that once more before I bite the bullet on starting over.

I’ll post back to the other thread I started. Hopefully I can figure something out without having to re-do the entire DB…

Thanks for all of your help! I know you guys put in a ton of time with FOG and it’s very appreciated!!

Cheers!
