  Hi @Tom-Elliott – thank you for your help! The client is UEFI.

  I probably should have mentioned that the main symptom I’m trying to figure out is the client giving up with PXE-E16: No valid offer received after a few minutes of trying PXE boot.

  Interestingly, when I tried also listening to port 4011 with my initial config file, there was no additional traffic being picked up.

  When I used the version you suggested (with the server’s IP switched in of course), the tcpdump actually no longer shows any responses to the client’s requests, and the PXE boot errors out faster with PXE-E18: Server response timeout.

  tcpdump: listening on eno1, link-type EN10MB (Ethernet), snapshot length 262144 bytes 16:08:07.096920 IP (tos 0x0, ttl 64, id 29391, offset 0, flags [none], proto UDP (17), length 375) 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from <client’s mac address>(oui Unknown), length 347, xid 0x92c2c13c, Flags [Broadcast] Client-Ethernet-Address <client’s mac address>(oui Unknown) Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message (53), length 1: Discover MSZ (57), length 2: 1472 Parameter-Request (55), length 35: Subnet-Mask (1), Time-Zone (2), Default-Gateway (3), Time-Server (4) IEN-Name-Server (5), Domain-Name-Server (6), Hostname (12), BS (13) Domain-Name (15), RP (17), EP (18), RSZ (22) TTL (23), BR (28), YD (40), YS (41) NTP (42), Vendor-Option (43), Requested-IP (50), Lease-Time (51) Server-ID (54), RN (58), RB (59), Vendor-Class (60) TFTP (66), BF (67), GUID (97), Unknown (128) Unknown (129), Unknown (130), Unknown (131), Unknown (132) Unknown (133), Unknown (134), Unknown (135) GUID (97), length 17: 0.128.226.9.231.152.246.237.17.132.7.227.255.61.233.42.0 NDI (94), length 3: 1.3.16 ARCH (93), length 2: 7 Vendor-Class (60), length 32: "PXEClient:Arch:00007:UNDI:003016" 16:08:10.881261 IP (tos 0x0, ttl 64, id 29392, offset 0, flags [none], proto UDP (17), length 375) 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from <client’s mac address>(oui Unknown), length 347, xid 0x92c2c13c, secs 4, Flags [Broadcast] Client-Ethernet-Address <client’s mac address>(oui Unknown) Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message (53), length 1: Discover MSZ (57), length 2: 1472 Parameter-Request (55), length 35: Subnet-Mask (1), Time-Zone (2), Default-Gateway (3), Time-Server (4) IEN-Name-Server (5), Domain-Name-Server (6), Hostname (12), BS (13) Domain-Name (15), RP (17), EP (18), RSZ (22) TTL (23), BR (28), YD (40), YS (41) NTP (42), Vendor-Option (43), Requested-IP (50), Lease-Time (51) Server-ID (54), RN (58), RB (59), Vendor-Class (60) TFTP (66), BF (67), GUID (97), Unknown (128) Unknown (129), Unknown (130), Unknown (131), Unknown (132) Unknown (133), Unknown (134), Unknown (135) GUID (97), length 17: 0.128.226.9.231.152.246.237.17.132.7.227.255.61.233.42.0 NDI (94), length 3: 1.3.16 ARCH (93), length 2: 7 Vendor-Class (60), length 32: "PXEClient:Arch:00007:UNDI:003016" 16:08:18.968033 IP (tos 0x0, ttl 64, id 29393, offset 0, flags [none], proto UDP (17), length 375) 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from <client’s mac address>(oui Unknown), length 347, xid 0x92c2c13c, secs 12, Flags [Broadcast] Client-Ethernet-Address <client’s mac address>(oui Unknown) Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message (53), length 1: Discover MSZ (57), length 2: 1472 Parameter-Request (55), length 35: Subnet-Mask (1), Time-Zone (2), Default-Gateway (3), Time-Server (4) IEN-Name-Server (5), Domain-Name-Server (6), Hostname (12), BS (13) Domain-Name (15), RP (17), EP (18), RSZ (22) TTL (23), BR (28), YD (40), YS (41) NTP (42), Vendor-Option (43), Requested-IP (50), Lease-Time (51) Server-ID (54), RN (58), RB (59), Vendor-Class (60) TFTP (66), BF (67), GUID (97), Unknown (128) Unknown (129), Unknown (130), Unknown (131), Unknown (132) Unknown (133), Unknown (134), Unknown (135) GUID (97), length 17: 0.128.226.9.231.152.246.237.17.132.7.227.255.61.233.42.0 NDI (94), length 3: 1.3.16 ARCH (93), length 2: 7 Vendor-Class (60), length 32: "PXEClient:Arch:00007:UNDI:003016" 16:08:35.140038 IP (tos 0x0, ttl 64, id 29394, offset 0, flags [none], proto UDP (17), length 375) 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from <client’s mac address>(oui Unknown), length 347, xid 0x92c2c13c, secs 28, Flags [Broadcast] Client-Ethernet-Address <client’s mac address>(oui Unknown) Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message (53), length 1: Discover MSZ (57), length 2: 1472 Parameter-Request (55), length 35: Subnet-Mask (1), Time-Zone (2), Default-Gateway (3), Time-Server (4) IEN-Name-Server (5), Domain-Name-Server (6), Hostname (12), BS (13) Domain-Name (15), RP (17), EP (18), RSZ (22) TTL (23), BR (28), YD (40), YS (41) NTP (42), Vendor-Option (43), Requested-IP (50), Lease-Time (51) Server-ID (54), RN (58), RB (59), Vendor-Class (60) TFTP (66), BF (67), GUID (97), Unknown (128) Unknown (129), Unknown (130), Unknown (131), Unknown (132) Unknown (133), Unknown (134), Unknown (135) GUID (97), length 17: 0.128.226.9.231.152.246.237.17.132.7.227.255.61.233.42.0 NDI (94), length 3: 1.3.16 ARCH (93), length 2: 7 Vendor-Class (60), length 32: "PXEClient:Arch:00007:UNDI:003016" ^C 4 packets captured 4 packets received by filter 0 packets dropped by kernel

  @Tom-Elliott said in FOG Docker image:

  @Cpasjuste if you have github you likely have ability to have copilot to help read the repo and help you build the README if you find it lacking.

  Just thoughts, but thanks for this.

  Hi @Tom-Elliott ! I’m not a big fan of ia but i should take a closer look someday 🙂

  @Valer Thanks for the report and the writeup, that’s a good catch. You’re right about the cause. Debian 13 dropped the sysv-rc-conf package since it’s fully on systemd now, so the installer chokes trying to apt-get it. We never actually use that tool on a systemd system anyway, it only ever got called on the old non-systemd paths, so it was just dead weight on Trixie.

  I pushed a fix to working-1.6. It leaves the package off the list on Debian 13 and up, and it also strips it out of a cached .fogsettings so an in-place upgrade doesn’t drag it back in. Older Debian keeps installing it like before so nothing changes there.

  If you want to get moving before you pull the update, you can either grab the latest working-1.6 and rerun the installer, or just open /opt/fog/.fogsettings and delete sysv-rc-conf from the packages line, then run the installer again. Either one gets you past it.

  Let me know if you hit anything else on Trixie.
