I changed the code to PHP and now it works, so I think it was something security related from the browser.

@Tom-Elliott
Alright, that was the point where I was confused too. Now I understood.

@Tom-Elliott

I mean is there a setting in FOG where I can change it or does FOG just uses the version that is available?

@george1421 @Tom-Elliott

We just saw our switches can’t process v3… Is it possible to change a setting that FOG uses the v2 of igmp?

@george1421

Yea, it’s not possible having the FOG and the target pcs on the same subnet. Our switches have the option active igmp. And I see a warning on the switches that they get a v3 query but the device is just configured for igmp v2. But that I have to look with our service provider.

@Tom-Elliott

That’s a good idea to reduce the limit. But our priority will be to get multicast to work. I’m pretty sure somewhere in our network structure is the error why it’s not working yet.
Since we have to do that multiply times in a week, reducing the time would be great.

And here are the logs: https://pastebin.com/JQadkbZ0

@george1421

The current status: FOG and client pc in different VLANs. We have managed switches where the streams should be forwarded (we don’t managed them ourselves). We started a multicast session for 6 pcs. They are all going into the Partclone windows, but don’t start the deployment process.

In the active task tab I have once (under “Active Tasks”) 6 task (for each pc one) and under “Active Multicast Tasks” I have one for the whole group. State is in “In-Progess” and status is “0”.

edit: I somehow can’t post the logs because they are marked as spam

@george1421
We have the following structure:

• FOG Server on office VLAN
• 3 rooms with separate VLANs each (because they have different rights in the network, but all can access the FOG server)
• FOG server is running on the VM but on ssd, if I’m correct
• All are linked with aruba managed switches

Somewhere I read that it’s possible to have it with different VLANs if the udp stream is forwarded.
The weird thing is: we didn’t had the problems in the past… so yea something in the network could be the problem.

@george1421 The 10 pcs getting all the same image, but through the normal deployment. It would be still better to use multicast deploying in that case?

Edit: I tried the multicast for one group now, they starting the Partclone part but don’t start the deplayoment. As I seen the FOG server and the client pcs has to be in the same VLAN for multicast? That’s not our case, they have different ones.

@george1421 On that place we have 10 pcs, but all are connected at a one gigabyte port. So when all are deplyoing at the same time, the rate is decreased. If just one is deploying the rate is at that 5.7 GB/min.
But you saying that the problem isn’t something on the FOG more like outside, like the network connection?

We tried to reset 8 pcs yesterday. 3 of them stuck at 22, 24 and 25% like shown in the image. These are also always different pcs.
