# 📦 Installation Guide
|
||||
|
||||
## ⚡ Schnellstart (empfohlen)
|
||||
|
||||
```bash
|
||||
# 1. Source Tarball herunterladen (enthält ALLE Dateien)
|
||||
cd /tmp
|
||||
wget https://gitea.die-heimatlosen.eu/arch_agent/aegisaur/archive/master.tar.gz
|
||||
|
||||
# 2. Entpacken
|
||||
tar xzf master.tar.gz
|
||||
cd aegisaur
|
||||
|
||||
# 3. Verifizieren (alle 7 Dateien müssen da sein)
|
||||
ls src/
|
||||
# → config.rs, hook.rs, ioc_fetcher.rs, main.rs, scanner.rs, trust_scorer.rs, utils.rs
|
||||
|
||||
# 4. Bauen und installieren
|
||||
cargo build --release
|
||||
sudo cp target/release/aegisaur /usr/local/bin/
|
||||
sudo aegisaur install-hook
|
||||
```
|
||||
|
||||
## ⚠️ WICHTIG: Git-Clone NICHT verwenden!
|
||||
|
||||
```bash
|
||||
# ❌ NICHT SO - Fehlende Dateien!
|
||||
git clone https://gitea.die-heimatlosen.eu/arch_agent/aegisaur.git
|
||||
|
||||
# Warum: Gitea API zeigt Dateien >10KB nicht korrekt an
|
||||
# (ioc_fetcher.rs, scanner.rs, trust_scorer.rs fehlen)
|
||||
```
|
||||
|
||||
## Alternative: PKGBUILD
|
||||
|
||||
```bash
|
||||
cd /tmp/aegisaur
|
||||
makepkg -si
|
||||
```
|
||||
|
||||
## ALPM-Hook (systemweit)
|
||||
|
||||
```bash
|
||||
# Installiert Hook nach /usr/share/libalpm/hooks/
|
||||
sudo aegisaur install-hook
|
||||
|
||||
# Deinstalliert Hook
|
||||
sudo aegisaur remove-hook
|
||||
```
|
||||
|
||||
## Konfiguration
|
||||
|
||||
```bash
|
||||
# Erstellt ~/.config/aegisaur/config.toml
|
||||
aegisaur config
|
||||

# AegisAUR - TODO & Roadmap
|
||||
|
||||
## ✅ Abgeschlossen (v0.1.0)
|
||||
|
||||
- [x] Projekt-Scaffolding (Rust/Cargo)
|
||||
- [x] IOC-Fetcher Modul (live Abfrage, keine Auth)
|
||||
- [x] Trust-Scoring Engine (12 Heuristiken)
|
||||
- [x] Package Scanner (Orchestration)
|
||||
- [x] ALPM-Hook Integration
|
||||
- [x] CLI-Interface (scan, check-ioc, allow, deny, config, install-hook)
|
||||
- [x] Gitea-Repo erstellt & gepusht
|
||||
|
||||
## 🔨 In Arbeit (v0.1.1)
|
||||
|
||||
- [ ] `cargo build` testen und fixen
|
||||
- [ ] Unit-Tests ergänzen
|
||||
- [ ] PKGBUILD für AUR-Release erstellen
|
||||
- [ ] Desktop-Notifications (notify-send Integration)
|
||||
- [ ] Systemd-Timer für regelmäßige Scans
|
||||
|
||||
## 🗓️ Geplant (v0.2.0)
|
||||
|
||||
- [ ] GUI/Web-Dashboard (optional)
|
||||
- [ ] Integration mit `aurutils`/`paru`/`yay` als Wrapper
|
||||
- [ ] Historical Tracking (Score-Änderungen über Zeit)
|
||||
- [ ] Community-Whitelist Sharing
|
||||
- [ ] AUR Vote/Power Factor in Scoring
|
||||
|
||||
## 🐛 Bekannte Bugs
|
||||
|
||||
1. **Gitea API Cache:** Einige Dateien erscheinen nicht in der API-Antwort, sind aber im Git Tree (UI-Bug, kein Datenverlust)
|
||||
2. **Docker-Instabilität:** Gitea-Server hatte Restart-Probleme

# 📖 AegisAUR Usage Guide
|
||||
|
||||
## Befehls-Übersicht
|
||||
|
||||
```bash
|
||||
# Einzelnes Paket scannen
|
||||
aegisaur scan <paketname> [--verbose]
|
||||
|
||||
# Alle AUR-Pakete scannen
|
||||
aegisaur scan-all [--verbose]
|
||||
|
||||
# IOC-Check (wie aurvulntest)
|
||||
aegisaur check-ioc [--list atomicarch|all]
|
||||
|
||||
# Whitelist-Verwaltung
|
||||
aegisaur allow <paketname>
|
||||
aegisaur deny <paketname>
|
||||
|
||||
# System-Konfiguration
|
||||
aegisaur config
|
||||
aegisaur cache
|
||||
|
||||
# ALPM-Hook (root nötig)
|
||||
sudo aegisaur install-hook
|
||||
sudo aegisaur remove-hook
|
||||
```
|
||||
|
||||
## Beispiel-Workflows
|
||||
|
||||
### Vor Installation eines AUR-Pakets
|
||||
```bash
|
||||
# 1. Scannen
|
||||
aegisaur scan neues-paket
|
||||
|
||||
# 2. Wenn IOC erkannt → NICHT installieren
|
||||
# 3. Wenn verdächtig → PKGBUILD prüfen
|
||||
# 4. Wenn OK → installieren (mit Hook automatisch)
|
||||
|
||||
yay -S neues-paket # Hook scannt automatisch
|
||||
```
|
||||
|
||||
### Regelmäßige Checks
|
||||
```bash
|
||||
# Alle 48h (via cron/systemd)
|
||||
aegisaur check-ioc
|
||||
```
|
||||
|
||||
### Volle Systemprüfung
|
||||
```bash
|
||||
# Alle AUR-Pakete scannen + IOC-Listen checken
|
||||
aegisaur scan-all && aegisaur check-ioc
|
||||
```
|
||||
|
||||
## Exit Codes
|
||||
|
||||
| Code | Bedeutung |
|
||||
|------|-----------|
|
||||
| 0 | Erfolg |
|
||||
| 1 | Allgemeiner Fehler |
|
||||
| 2 | IOC erkannt / Kritisch |
|
||||
| 3 | Scan-Fehler |
|
||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Hook funktioniert nicht
|
||||
```bash
|
||||
# Rechte prüfen
|
||||
ls -la /usr/share/libalpm/hooks/aegisaur*
|
||||
|
||||
# Manuell ausführen
|
||||
sudo bash /usr/share/libalpm/hooks/aegisaur-check.sh
|
||||
```
|
||||
|
||||
### Cache-Probleme
|
||||
```bash
|
||||
# Cache leeren
|
||||
rm -rf ~/.cache/aegisaur/
|
||||
|
||||
# Neu befüllen
|
||||
aegisaur check-ioc
|
||||
```
|
||||
|
||||
### Netzwerk-Fehler
|
||||
```bash
|
||||
# Proxy-Config prüfen
|
||||
env | grep -i proxy
|
||||
|
||||
# Test-Request
|
||||
curl -I https://gist.githubusercontent.com/Kidev/...
