    • RE: Subnet Groups Plugin | Dynamic Groups Not Working

      I’ve done some trivial troubleshooting, and it seems that the ‘RequestClientInfo’ action is not taking place thus the plugin is never being called to run.

      I’ve tried installing the FOG Client (rather than relying on the machine booting to fog via PXE), and power cycling a test machine, but this did not make a difference.

      Reviewing previous forum post @mattmurdock78 had a similar issue and wrote a trigger, unfortunately the file he attached is not available.

      @Tom-Elliott, I understand you were not the main author of the plugin but if you have the opportunity to review and advise if the plugin ‘should’ be working or is deprecated and potentially how I can try to proceed it would be greatly appreciated.

    • Subnet Groups Plugin | Dynamic Groups Not Working

      Hello, I have a FOG server setup on version 1.5.10.1719.

      I have multicast working across VLANS/Subnets and it’s all splendid.

      My challenge now is that I want to provision a subset of computers based on what subnet they are on. As different labs will need different images pushed to them and computers can get moved between labs at any time.

      I saw that the ‘Subnet Groups’ add-in existed and thought this was the exact answer I needed! I added it, I created a group with the address range of one of my test machines, and booted it into FOG, but alas it was never added to the group.

      I don’t quite grasp how the add-in works and how it interacts with the hosts IP addresses.

      If anyone has any insight into this it would be greatly appreciated!

    • RE: Multicasting Stuck on Partclone Screen

      My RP address was not pointing to my FOG server 🤦

      Once this was adjusted, multicast is functional. Definitely a good reminder to start small.

    • RE: Multicasting Stuck on Partclone Screen

      I was able to create a multicast task from the FOG server, and while the main client was stuck in the partclone screen, I was able to launch another client on the same VLAN in debug mode and run “udp-receiver --portbase <PORT FROM LOGS>” and it was receiving the stream of traffic and showed up in the ‘multicast.log.udpcast’ logs.

      This makes me curious as to what udp-receiver command the client is running when booting into partclone as it never joins the session and just sits at that screen indefinitely.

    • RE: Multicasting Stuck on Partclone Screen

      I see that the images did not load so I uploaded my multicast settings to imgur.

      Also wanted to note no ports are being blocked within the VLAN.

      I’ll continue troubleshooting but appreciate anyone’s 2 cents on this.

    • Multicasting Stuck on Partclone Screen

      Hello everyone,

      I’m back with more multicasting issues. When I attempt to multicast the task starts, but on the client end, they are left sitting at the first partclone screen after listing the image.

      On the networking side, we intend on using 3 VLANS but I have kept it all on the same VLAN to get the initial test working before complicating things.

      I am on Ubuntu 24.04 and FOG v 1.5.10.1719

      We have the following setup in regards to networking:

      1. Option 66 + 67 (Unicast is confirmed working, and it boots successfully
      2. IGMP snooping enabled
      3. PIM (SM)
      4. RP

      I have also followed the steps to test multicast manually with the udp-sender and udp-receiver commands and that is working within the same VLAN and outside.

      If anyone has any suggestions I would really appreciate it. I understand this is a common issue judging by similar forum posts but I was unable to find a resolution from past posts.

      When I start the task the log has the following:```

    • RE: Unable to Multicast | Unable to locate udp-sender

      I found the issue!

      The udpsender path on my system was “/usr/sbin/udp-sender”

      The path that is set within config.class.php is:

      define('UDPSENDERPATH', '/usr/local/sbin/udp-sender');
      

      I ran the following and restarted the FOGMulticastManager to resolve:

      sudo ln -s /usr/sbin/udp-sender /usr/local/sbin/udp-sender
      

      And we have logs now! Time to begin multicast testing 🥳

      I did a fresh install utilizing Debian 13 and the current Dev branch of FOG and received the same error.

    • Unable to Multicast | Unable to locate udp-sender

      Hello,

      I am trying to get multicast working with FOG and whenever I attempt to, the screen is stuck indefinitely on the first partclone screen after initializing.

      The logfile simply states “Unable to locate udp-sender!.”

      I am on Ubuntu 24.04.3
      I am utilizing the latest stable version of FOG.

      I can restart the ‘FOGMulticastManager’ service and all it does it update the log file with the current time the service launches and states the same message.

      I believed there may have been some corruption to my files and did a fresh install of FOG & Ubuntu and the log just had that message in it immediately after install.

      If I run the ‘which udp-sender’ command I receive "/usr/sbin/udp-sender’

      I have also tried removing and reinstalling udp-sender to no avail.

      Has anyone come across this before? If not does anyone have multicast working on the stable version mind sharing what Linux OS they are running it off of? I am still in the PoC phase of setting up FOG and don’t mind changing Linux flavours.

      Thanks in advance!

    • ip helper address instead of DHCP options 66 + 67

      Hello! I am in the process of configuring a FOG server and need some insight into if I can use an ip helper address to point the imaging computers to DHCP & TFTP (FOG) instead of setting DHCP options 66 + 67. I know this is suggested for WDS deployments across multiple subnets/vlans but am unsure if this is supported/working in FOG.

      Thanks in advance!
