Yes and so have I. You would need some way to dynamically change the network adapter defined in the global FOG settings to change the network adapter. You might also need to change a file called /tftpboot/default.ipxe to point to different interfaces. You might be able to get around this by setting up multiple tftp servers on the fog server, where each tftp server bound to a different interface and had a different home directory, that would be more of a long term change. And then you need to work out a way to update the imaging network interface in the fog settings depending on what interface you wanted to image using. There may be more crafty ways about doing this, but this is just off the top of my head.

So vacation is done, back to this problem.

I see, there are some more difficulties on the way.

In the meantime my colleague looked into the router and found a PIM function (Protocol Independent Multicast) and activated that.
I started a test run and the PCs are going in the Partclone process (Starting to restore image). But they are stuck in that screen, like they waiting for something or can’t get the data?

Is there something that I can look up, to see where the problem is?

Thanks in advance.

@george1421 said in FOG Multicast on different VLANs:

Where the magic happens is on your router between the vlans. Your router needs to be configured to forward muticast traffic between the vlans.

As far as I know that’s the problem. The router between is a Sophos which can’t forward that traffic (Asked a 2nd person about that).

To the multiple adapter topic: I looked up some threads yesterday where people tried it (for example: https://forums.fogproject.org/topic/12907/multi-network-multi-nic-fog-server-config-help/3)

Hi,

We have currently a FOG server running on VLAN 1, that unicast round about 40 pcs in VLAN 2 - 5 (not the best approach). To optimize that, I wanted to try to run multicast, but sadly our switches are just Layer 2 switches and they don’t support that on other VLAN (as far as I read, not a big network guy myself).

So my idea was now: The FOG server is running on a VM, is it possible to give that machine just 4 more virtual network adapter (for each VLAN one) and reconfigure the IP address on the clients to one thats on there VLAN? Somehow I think that would be too easy.

Or do I need to have a second FOG Server in that specific VLAN that just using the main FOG storage?

What else could I do to optimize the workflow?

Thanks in advance!

@Tom-Elliott Which information would help you to understand the problem more?

Secure Boot is disabled at the moment.

Hi,

I wanted to install FOG on a new location. Installed on a VM, signed the files because of Windows 11 and you can access the dashboard from the other PCs.
Now we trying to boot the first PC through PXE but it stucks at “Checking Media Presence… Media Present… Start PXE over …”. It stops at this point.
Does anybody know what the problem could be? Thanks

@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.

@george1421 It’s always different, sometimes at 34%, then 56%, then another number. But the next time it happens I will take a picture of it.
The fog version is 1.5.10

Hi,

we noticed in the last time, that we have issues with the deployment process. Sometimes the deployment is getting stuck at a random % number.
The problem happens with different pcs and different images. Is there somewhere a log file which could give me a hint, what the problem could be?

@sega Whoops, yea I meant that.
