# GE Aerospace PXE Boot Server
Automated, air-gapped PXE boot server for deploying GE Aerospace Windows images. Built on Ubuntu 24.04 Server with zero-touch provisioning via autoinstall and Ansible.
## Overview
This project provides a complete, repeatable build process for a PXE boot server that serves Windows PE images to client machines on an isolated network. Everything runs offline after initial setup — no internet required on the target server.
### Boot Chain
```
Client PXE boot (UEFI Secure Boot)
-> iPXE (TFTP, Broadcom-signed for Secure Boot)
-> iPXE boot menu (HTTP, port 4433)
-> User selects boot option:
├── Windows PE -> wimboot -> boot.wim -> startnet.cmd -> Samba share -> Image deployment
├── Clonezilla -> vmlinuz/initrd -> Disk cloning/imaging
├── Blancco -> vmlinuz/initrd -> NIST 800-88 drive erasure
└── Memtest86+ -> Memory diagnostics
```
### Services
| Service | Port | Purpose |
|-------------|-----------|------------------------------------------|
| dnsmasq | 67/udp | DHCP (10.9.100.10-100, 12h lease) |
| dnsmasq | 69/udp | TFTP (serves ipxe.efi) |
| Apache | 80/tcp | HTTP (wimboot, WinPE boot files, proxy) |
| Apache | 4433/tcp | iPXE boot script (GetPxeScript.aspx) |
| Samba | 445/tcp | Deployment content + Clonezilla + Blancco|
| Flask Webapp| 9009/tcp | Web management interface |
### Network
- **PXE server IP:** `10.9.100.1/24`
- **DHCP range:** `10.9.100.10` - `10.9.100.100`
- **Firewall:** UFW deny-by-default, only service ports open
## Quick Start
### Prerequisites
**On your workstation (internet-connected):**
- Ubuntu 24.04 (or Linux Mint / similar) for downloading packages
- Ubuntu Server 24.04 ISO
- GE Aerospace Media Creator LITE (for WinPE images)
- USB drive >= 8 GB (32+ GB if bundling WinPE images)
**GE Access Packages (MyAccess portal):**
- EPM Rufus Exception Request
- EPM DT Functions
- DLP - Encrypted Removable (USB) Long Term Access
### Step 1: Download Offline Packages
```bash
./download-packages.sh
```
Downloads all .deb packages and Python wheels for offline installation (~140 MB of debs, ~20 MB of wheels).
### Step 2: Prepare Boot Tools (optional)
```bash
./prepare-boot-tools.sh /path/to/blancco.iso /path/to/clonezilla.zip /path/to/memtest.bin
```
Extracts and configures boot tool files (Blancco, Clonezilla, Memtest86+). Automatically patches Blancco's config.img to auto-save erasure reports to the PXE server's Samba share.
### Step 3: Build the USB
```bash
sudo ./build-usb.sh /dev/sdX /path/to/ubuntu-24.04-live-server-amd64.iso
```
Creates a bootable USB with two partitions:
- **Partition 1:** Ubuntu Server installer
- **Partition 2:** CIDATA (autoinstall config, offline .debs, pip wheels, Ansible playbook, webapp, boot tools)
### Step 4: Install on Target Server
1. Insert USB into the target machine
2. Press F12 and boot from USB
3. Ubuntu auto-installs with no interaction
4. After reboot, the first-boot script:
- Installs all offline .deb packages
- Runs the Ansible playbook (configures dnsmasq, Apache, Samba, UFW, webapp)
- Configures static IP `10.9.100.1/24`
5. Move the server's wired NIC to the isolated PXE switch
### Step 5: Access the Web Interface
Open `http://10.9.100.1:9009` from any machine on the isolated network.
## Web Management Interface
The Flask webapp (port 9009) provides a browser-based management UI:
- **Dashboard** — Service status overview, disk usage, connected DHCP clients
- **Image Import** — Import WinPE deployment images from USB drives
- **Unattend Editor** — Edit Windows unattend.xml files per image type (XML syntax highlighting)
- **startnet.cmd Editor** — Modify the startnet.cmd inside boot.wim without Windows (uses wimtools)
- **Clonezilla Backups** — Upload, download, and manage disk backup images
- **Blancco Reports** — View, download, and manage drive erasure reports (auto-collected via Samba)
- **Audit Log** — Activity history for all write operations (imports, edits, deletes)
### Image Types Supported
| Image Type | Domain | Description |
|----------------------|-----------------|-------------------------|
| gea-standard | geaerospace.com | Standard desktop |
| gea-engineer | geaerospace.com | Engineering desktop |
| gea-shopfloor | geaerospace.com | Shop floor kiosk |
| ge-standard | ge.com | Standard desktop |
| ge-engineer | ge.com | Engineering desktop |
| ge-shopfloor-lockdown| ge.com | Shop floor (locked) |

## Testing with KVM
A test VM script is included for validating the full provisioning pipeline without dedicated hardware:
```bash
# Download Ubuntu Server ISO
wget -O ~/Downloads/ubuntu-24.04.3-live-server-amd64.iso \
https://releases.ubuntu.com/noble/ubuntu-24.04.3-live-server-amd64.iso
# Launch test VM (requires libvirt/KVM)
sudo ./test-vm.sh ~/Downloads/ubuntu-24.04.3-live-server-amd64.iso
# Watch install progress
sudo virsh console pxe-test
# Clean up when done
sudo ./test-vm.sh --destroy
```
The test VM creates an isolated libvirt network (10.9.100.0/24) and runs the full autoinstall + Ansible provisioning.
## Samba Shares
| Share | Path | Purpose |
|-----------------|---------------------------|--------------------------------|
| winpeapps | /srv/samba/winpeapps | WinPE deployment images |
| clonezilla | /srv/samba/clonezilla | Clonezilla disk backup images |
| blancco-reports | /srv/samba/blancco-reports| Blancco erasure reports (auto) |
All shares use guest access (no authentication) for ease of use on the isolated network.
## Blancco Drive Erasure
Blancco Drive Eraser is configured to automatically save XML erasure reports to the PXE server's Samba share (`blancco-reports`). The `prepare-boot-tools.sh` script patches Blancco's `config.img` to set:
- Network share hostname: `10.9.100.1`
- Share path: `blancco-reports`
- Auto-backup: enabled
- Erasure standard: NIST 800-88 Purge
Reports are viewable and downloadable from the web interface at `http://10.9.100.1:9009/reports`.
## Known Issues / TODO
- **wimtools** must be downloaded with `download-packages.sh` before building USB (used for startnet.cmd editing)
- **Apache VirtualHost conflict**: Two VirtualHosts on port 80 (default site and pxe-webapp proxy) — should disable default or merge
- **WinPE boot files** (wimboot, BCD, boot.sdi, bootx64.efi, boot.stl, boot.wim) must be manually placed on USB or sourced from the legacy `WestJeff` playbook folder
- **CSRF protection** not yet implemented on webapp POST forms
- Test VM requires re-download of Ubuntu ISO if `--destroy` is run (fixed in latest test-vm.sh)
