    Wir können das noch für eine sanfte Methode erweitern, das ist die Datei robots.txt, wo man sich in alten Zeiten mal dran hielt. Einige Bots machen das, andere nicht. Praktisch, das o.g. Projekt bietet diese Datei auch an. Dann werden wir das kurz mal mit einbauen. ai-block.sh #!/bin/bash # Script um AI-Bots zu blocken # https://github.com/ai-robots-txt/ai.robots.txt/tree/main mkdir /root/AI-test cd /root/AI-test ## Daten holen curl -O https://raw.githubusercontent.com/ai-robots-txt/ai.robots.txt/master/nginx-block-ai-bots.conf curl -O https://raw.githubusercontent.com/ai-robots-txt/ai.robots.txt/master/robots.txt ## Daten in nginx einbauen mv nginx-block-ai-bots.conf /etc/nginx/blocklists/ mv robots.txt /var/www/html ## NGINX neustarten systemctl restart nginx.service Damit das in nginx funktioniert. Den Server Block um folgendes erweitern. # Serve robots.txt directly from Nginx location = /robots.txt { root /var/www/html; try_files $uri =404; } Kurzer Test https://<DOMAIN>/robots.txt Ergebnis User-agent: AI2Bot User-agent: Ai2Bot-Dolma User-agent: Amazonbot User-agent: anthropic-ai User-agent: Applebot User-agent: Applebot-Extended User-agent: Brightbot 1.0 User-agent: Bytespider User-agent: CCBot User-agent: ChatGPT-User User-agent: Claude-Web User-agent: ClaudeBot User-agent: cohere-ai User-agent: cohere-training-data-crawler User-agent: Crawlspace User-agent: Diffbot User-agent: DuckAssistBot User-agent: FacebookBot User-agent: FriendlyCrawler User-agent: Google-Extended User-agent: GoogleOther User-agent: GoogleOther-Image User-agent: GoogleOther-Video User-agent: GPTBot User-agent: iaskspider/2.0 User-agent: ICC-Crawler User-agent: ImagesiftBot User-agent: img2dataset User-agent: imgproxy User-agent: ISSCyberRiskCrawler User-agent: Kangaroo Bot User-agent: Meta-ExternalAgent User-agent: Meta-ExternalFetcher User-agent: OAI-SearchBot User-agent: omgili User-agent: omgilibot User-agent: PanguBot User-agent: Perplexity-User User-agent: PerplexityBot User-agent: PetalBot User-agent: Scrapy User-agent: SemrushBot-OCOB User-agent: SemrushBot-SWA User-agent: Sidetrade indexer bot User-agent: Timpibot User-agent: VelenPublicWebCrawler User-agent: Webzio-Extended User-agent: YouBot Disallow: /

    @masko Danke für die Ergänzung. Um den Code zu markieren, kannst Du im Texteditor auf </> klicken oder einfach 4 Leerzeichen vor den Code setzen. Dann sieht es besser aus Und Willkommen im Forum!

    Heute mal drüber gestolpert, das es auch so was geben kann. root@pve2:~# zpool status pool: pool_NAS state: ONLINE status: Some supported and requested features are not enabled on the pool. The pool can still be used, but some features are unavailable. action: Enable all features using 'zpool upgrade'. Once this is done, the pool may no longer be accessible by software that does not support the features. See zpool-features(7) for details. scan: scrub repaired 0B in 00:20:50 with 0 errors on Sun Apr 13 00:44:51 2025 config: NAME STATE READ WRITE CKSUM pool_NAS ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 ata-WDC_WDS100T1R0A-68A4W0_230520800733 ONLINE 0 0 0 ata-WDC_WDS100T1R0A-68A4W0_230520801376 ONLINE 0 0 0 errors: No known data errors Was machen?
