Every server has an imaging NIC (static, the only one that serves
DHCP/TFTP/HTTP boot/SMB) and a GE corporate NIC (DHCP client, SSH and the
webapp on 9009). The playbook guessed the PXE NIC and the installer put
172.16.9.1/24 on every en* NIC, so a two-NIC box could answer on the GE
network.
- New per-site vars pxe_nic_mac / corp_nic_mac (required, from
playbook/site-vars.yml or -e; template site-vars.example.yml), stable
names pxe_nic_name / corp_nic_name (default pxe0 / corp0, overridable),
pxe_server_ip, pxe_subnet, DHCP range. pxe_imaging_mac / pxe_ge_mac are
derived from them. The play stops before touching anything if a MAC is
unset, malformed, duplicated or not on the box (lists the box's NICs).
- Heuristic NIC detection and the single-NIC netplan task replaced by a
two-NIC netplan template (match macaddress + set-name), installed by
pxe-netplan-apply.sh: validate in a scratch root, back up, generate,
rename, apply, restore the previous config on any failure. cloud-init
network config disabled so it cannot rewrite it.
- dnsmasq: /etc/dnsmasq.d/pxe-nic-only.conf from the vars (interface=,
except-interface=, no-dhcp-interface=); dnsmasq.conf IP/range from vars.
- UFW per interface: imaging NIC 22, 67/udp, 69/udp, 80, 4433, 445, 139,
137/udp, 138/udp, 9009; GE NIC 22 and 9009 only. Old any-interface rules
and the stale 9011 rule removed after the new ones are in.
- sysctl drop-in: IPv4/IPv6 forwarding off; ip_nonlocal_bind so Apache
can bind the imaging IP before the address is up.
- Samba [global]: interfaces = 127.0.0.0/8 <imaging NIC>, bind interfaces
only. Apache 80 and 4433 on the imaging IP only; 9009 stays on all (TODO:
the webapp has no auth).
- autoinstall: DHCP only on en*, no static 172.16.9.1; apt geoip off and
offline-install fallback now that the corp NIC may have a lease.
- Blancco UEFI/Secure Boot: blancco_kver (7.0.0-34-generic) drives the
kernel, initramfs and modules builds instead of the running kernel;
outputs vmlinuz-ubuntu-70, kexec-initrd-70.img, kmod-<kver>.tar.gz as the
menu and blancco-init.sh expect; creates: guards keyed on the full kver.
Ubuntu's shimx64.efi.signed published as blancco/shimx64.efi.
download-packages.sh adds shim-signed, linux-generic-hwe-24.04 and the
pinned linux-image/modules/modules-extra for BLANCCO_KVER.
Rendered with the live MACs and names, netplan generate output is
identical to the live config; pxe-nic-only.conf and the Samba binding
match live directive for directive.
sbsigntool, zip and curl, the Zscaler root CA in the system store (GitHub is
TLS-intercepted on the corporate NIC; downloads.dell.com is not), and
/var/lib/pxe-webapp/updates.
Workstation reorganization:
- All build/deploy/helper scripts moved into scripts/ (paths updated to use
REPO_ROOT instead of SCRIPT_DIR so they resolve sibling dirs from the new
depth)
- New config/ directory placeholder for site-specific overrides
- Removed stale: mok-keys/, test-vm.sh, test-lab.sh, setup-guide-original.txt,
unattend/ (duplicate of moved playbook/FlatUnattendW10.xml)
- README.md and SETUP.md structure listings updated, dead "Testing with KVM"
section removed
- .claude/ gitignored
Enrollment share internal taxonomy (forward-looking; existing servers
unaffected since they keep their current boot.wim with flat paths):
- Single SMB share kept (WinPE only mounts one Y: drive), but content now
organised into ppkgs/, scripts/, config/, shopfloor-setup/, pre-install/{bios,
installers}, installers-post/cmm/, blancco/, logs/
- README.md deployed to share root explaining each subdir
- New playbook tasks deploy site-config.json + wait-for-internet.ps1 +
migrate-to-wifi.ps1 explicitly (were ad-hoc on legacy servers)
- BIOS subdir moved into pre-install/bios/, preinstall/ renamed to pre-install/
- startnet.cmd + startnet-template.cmd updated with new Y:\subdir\ paths
- Bumped GCCH PPKG references v4.9 -> v4.10
Blancco USB-build fixes (so next fresh USB install boots Blancco end-to-end
without the manual fixup we did against GOLD):
- grub-blancco.cfg: kernel/initrd switched HTTP -> TFTP (GRUB's HTTP module
times out on multi-MB files); added modprobe.blacklist=iwlwifi,iwlmvm,btusb
(WiFi drivers hang udev on Intel business PCs)
- grubx64.efi rebuilt from updated cfg
- Playbook task added to create /srv/tftp/blancco/ symlinks pointing at the
HTTP-served binaries
run-enrollment.ps1: OOBEComplete is now set AFTER PPKG install (Win11 22H2+
hangs indefinitely if OOBEComplete is set before the bulk-enrollment PPKG runs).
Also includes deploy-bios.sh / pull-bios.sh / busybox-static / models.txt
that were sitting untracked at the repo root.
