+# Schnellstart
+
+Diese Anleitung fuehrt dich von Null bis zum ersten laufenden Grid.
+
+## Voraussetzungen
+
+- Linux-Server mit Shell-Zugang

+
+```bash
+bash osmtool_main.sh install-grid-sim
+```
+
+1. Datenbank einrichten (Passwort per Umgebungsvariable):
+
+```bash
+export OSM_DB_PASS='DEIN_PASSWORT'
+bash osmtool_main.sh dbsetup
+```
+
+1. Grid starten:

+```
+
+1. Funktion pruefen:
+
+```bash
+bash osmtool_main.sh healthcheck
+```
+
+## Was install-grid-sim macht
+
+Der Shortcut fuehrt intern eine komplette Kette aus:
+
+- prepare-ubuntu
+- install-opensim-deps
+- install-dotnet8
+- server-check
+- install-opensim
+- configure-opensim
+
+## Naechster Schritt
+
+- Weboberflaeche einrichten: [Weboberflaeche](03-Weboberflaeche.md)

+# CLI Kurzbefehle
+
+Diese Kurzbefehle sind absichtlich kurz gehalten und fuer den Alltag gedacht.
+
+## Verfuegbare Kurzbefehle
+
+```bash
+bash osmtool_main.sh install-grid-sim
+bash osmtool_main.sh opensimstart
+bash osmtool_main.sh opensimstop
+bash osmtool_main.sh opensimrestart
+bash osmtool_main.sh healthcheck
+bash osmtool_main.sh smoketest
+bash osmtool_main.sh dailyreport
+bash osmtool_main.sh croninstall
+bash osmtool_main.sh cronlist
+bash osmtool_main.sh janusinstall
+bash osmtool_main.sh janusrestart
+bash osmtool_main.sh dbsetup
+bash osmtool_main.sh dbbackup
+```
+
+## Befehle mit Variablen
+
+### dbsetup
+
+Legt Datenbanken und Benutzer an.
+
+```bash
+export OSM_DB_PASS='DEIN_PASSWORT'
+bash osmtool_main.sh dbsetup
+```
+
+Optionale Variablen:
+
+- `OSM_DB_USER` (Standard: `opensim`)
+- `OSM_DB_ROOT_USER` (Standard: `root`)
+- `OSM_DB_ROOT_PASS` (Standard: leer)
+
+### dbbackup
+
+Sichert die Datenbank.
+
+```bash
+export OSM_DB_PASS='DEIN_PASSWORT'
+bash osmtool_main.sh dbbackup
+```
+
+Optionale Variablen:
+
+- `OSM_DB_USER` (Standard: `root`)
+- `OSM_DB_NAME` (Standard: `opensim`)
+
+## Wenn du volle Kontrolle brauchst
+
+Neben Kurzbefehlen kannst du auch den modularen Modus mit `--module` und `--action` nutzen.

+# Weboberflaeche
+
+Die Weboberflaeche liegt im Ordner `webphp/`.
+
+## Funktionen
+
+- Login-Schutz
+- Mehrsprachigkeit (`de`, `en`, `fr`, `es`)
+- Modul- und Aktionsauswahl
+- Kommando-Vorschau
+- Ausgabefenster
+- Live-Status fuer Screens, Ports und Artefakte
+
+## Wichtige Regel zur Konfiguration
+
+- Aktive Datei: `webphp/src/config.php`
+- Vorlage: `webphp/src/config.sample.php`
+
+Aenderungen werden nur aus `config.php` gelesen.
+
+## Minimal-Setup
+
+1. Dateien deployen
+2. `webphp/src/config.php` anpassen
+3. Webroot auf `webphp/public` setzen
+4. Runner-Skript ausfuehrbar machen
+
+## Live-Status anpassen
+
+In `webphp/src/config.php`:
+
+- `status_ports`
+- `status_screens`
+
+Wenn falsche Ports angezeigt werden, zuerst pruefen:
+
+1. Wurde `config.php` geaendert?
+2. Ist es die richtige Instanz?
+3. Browser-Hard-Reload gemacht (`Ctrl+Shift+R`)?
+
+## Referenz

+Detaillierte technische Anleitung: `webphp/README.md`

+# Sicherheit
+
+## Grundregeln
+
+- Produktivsystem nur mit Backups betreiben.
+- Webzugriff nach Moeglichkeit auf interne Netze/IPs begrenzen.
+- HTTPS verwenden.
+- Starkes Passwort in `webphp/src/config.php` setzen.
+
+## Login-Schutz (Web)
+
+Die Weboberflaeche enthaelt Brute-Force-Schutz:
+
+- Sperre nach mehreren Fehlversuchen pro IP
+- Zeitbasierte Entsperrung
+- Audit-Logging von Login-Ereignissen
+
+## Wichtige Einstellungen
+
+In `webphp/src/config.php`:
+
+- `auth_lockout_max_attempts`
+- `auth_lockout_seconds`
+- optional `auth_store_path`
+- optional `auth_audit_log_path`
+
+## Audit-Log
+
+Typische Events:
+
+- `login_success`
+- `login_failed_password`
+- `login_failed_locked`
+- `login_blocked`
+- `csrf_invalid`
+
+Nutze das Log fuer Nachverfolgung von Angriffen und Fehlbedienung.

+# Konfiguration
+
+## 1. Zentrale Bereiche
+
+Es gibt zwei Konfigurationswelten:
+
+- CLI/Skripte: ueber Parameter und Umgebungsvariablen
+- Web: ueber `webphp/src/config.php`
+
+## 2. Web-Konfiguration
+
+Wichtige Eintraege in `webphp/src/config.php`:
+
+- `session_key`: Schluessel fuer Session-Schutz
+- `web_password`: Login-Passwort fuer Web-UI
+- `command_timeout_seconds`: Timeout fuer Runner
+- `default_workdir`: Standard-Arbeitsverzeichnis
+- `status_ports`: Port-Check pro Profil
+- `status_screens`: Screen-Check pro Profil
+- `use_sudo` und `sudo_user`: optionaler sudo-Betrieb
+
+## 3. Sicherheitseinstellungen
+
+- `auth_lockout_max_attempts`
+- `auth_lockout_seconds`
+- optional `auth_store_path`
+- optional `auth_audit_log_path`
+
+## 4. Typische Stolpersteine
+
+- Nur `config.sample.php` geaendert statt `config.php`
+- Falscher Deploy-Pfad oder falsche Instanz
+- Browsercache zeigt alte Daten
+
+## 5. Empfehlung
+
+Aendere zuerst in einer Testumgebung. Dokumentiere eigene Abweichungen in einer separaten Betriebsdoku.

+# Backup und Restore
+
+## 1. Grundprinzip
+
+Jede groessere Aenderung startet mit einem Backup.
+
+Empfohlen:
+
+- Datenbank-Backup vor Updates
+- OAR-Backup vor Regionenumbauten
+- Regelmaessige automatisierte Sicherung per Cron
+
+## 2. Datenbank sichern (Kurzbefehl)
+
+```bash
+export OSM_DB_PASS='DEIN_PASSWORT'
+bash osmtool_main.sh dbbackup
+```
+
+## 3. Modulare Backup-Aktionen
+
+Beispiele (ausfuehrlicher Modus):
+
+```bash
+bash osmtool_main.sh --module backup --action db-backup --db-user root --db-pass DEIN_PASSWORT --db-name opensim --workdir /opt
+bash osmtool_main.sh --module backup --action oar-backup --workdir /opt --region sim1 --session sim1
+bash osmtool_main.sh --module backup --action full-backup --workdir /opt --db-user root --db-pass DEIN_PASSWORT --db-name opensim --region sim1 --session sim1 --compress true
+```
+
+## 4. Restore
+
+Restore-Funktionen laufen ueber das Modul `restore`.
+
+Vor einem produktiven Restore immer:
+
+- passenden Backupstand verifizieren
+- Zielsystem stoppen
+- optional Dry-Run oder Testsystem nutzen
+
+## 5. Aufbewahrung
+
+- Backups versioniert speichern
+- externe/offsite Kopie einplanen
+- Restore regelmaessig testen

+# Troubleshooting
+
+## 1. Live-Status zeigt falsche Ports
+
+Pruefen:
+
+1. Ports in `webphp/src/config.php` gesetzt?
+1. Richtige Umgebung/Instanz aufgerufen?
+1. Hard-Reload im Browser (`Ctrl+Shift+R`)?
+
+## 2. Login ploetzlich gesperrt
+
+Ursache:
+
+- Mehrere falsche Loginversuche fuehren zur IP-Sperre.
+
+Loesung:
+
+- `auth_lockout_seconds` abwarten
+- Audit-Log pruefen
+
+## 3. check_screens startet neu
+
+Erwartetes Verhalten:
+
+- kritische Ausfaelle fuehren zu Neustart
+- Status wird in `ProblemRestarts.log` protokolliert
+
+## 4. Befehle schlagen ohne erkennbare Ursache fehl
+
+Pruefen:
+
+1. Rechte auf Skripte vorhanden (`chmod +x`)
+1. Pfade korrekt (`/opt/...` vs andere Pfade)
+1. Abhaengigkeiten installiert (dotnet, mysqldump, screen)
+
+## 5. Web-UI startet Befehle nicht
+
+Pruefen:
+
+- runner-Skript vorhanden und ausfuehrbar
+- `runner_path` korrekt
+- `use_sudo` und `sudo_user` korrekt
+- sudoers-Eintrag fuer Runner vorhanden

+# Cronjobs
+
+Cronjobs helfen, wiederkehrende Aufgaben zu automatisieren.
+
+## 1. Kurzbefehle
+
+```bash
+bash osmtool_main.sh croninstall
+bash osmtool_main.sh cronlist
+```
+
+## 2. Manuelle Crontab-Befehle
+
+```bash
+crontab -l
+crontab -e
+```
+
+## 3. Beispiele
+
+```cron
+# Grid jeden Morgen um 05:00 neu starten
+0 5 * * * bash /opt/osmtool.sh autorestart
+
+# Alle 30 Minuten check_screens
+*/30 * * * * bash /opt/osmtool.sh check_screens
+```
+
+## 4. Empfehlungen
+
+- Logs aktivieren
+- Zeiten so legen, dass Nutzer moeglichst wenig beeinflusst werden
+- Neustarts mit Backup-Strategie kombinieren
