飞牛OS内网穿透Cloudflare Zero Trust + Uptime Kuma零成本远程访问 Cloudflare Zero Trust 隧道，一站式搞定 FNOS 面板、SSH 远程和 Uptime Kuma 监控的公网访问！飞牛小主机首先，在飞牛OS里搜索并安装 Uptime Kuma。Uptime Kuma安装好后直接登录，这是我们的核心监控台。接着，咱们打开 Cloudflare 官网，进入 Zero Trust 面板。Zero Trust在网路菜单里找到连接器，创建一个新隧道，名字随你起，比如叫 fnos。创建一个新隧道关键点来了：在连接器配置页面，复制那一串长长的 Token。Token把获取到的token填入uptime kuma反向代理uptime kuma反向代理现在，我们要把内网地址发给公网。在 Cloudflare的 已发布应用程序路由里添加三条：第一条，配置 http://localhost:3001，绑定你的域名，用来访问 Uptime Kuma；Uptime Kuma第二条，配置 http://172.20.0.1:5666，这就是你的 FNOS 管理面板；FNOS 管理面板第三条，配置 tcp://172.20.0.1:22，这是给 SSH 远程连接预留的通道。SSH 远程这里的 172.20.0.1 是 Docker 的网关地址，非常稳定。最后测试一下，直接输入域名访问，测试ssh功能也都正常测试

使用 robots.txt 阻止 AI 爬虫，给服务器“减负” 最近辣鸡轻量服务器资源频频飙红，开始还以为流量暴涨，自己要发了。结果一看日志——原来是每天被各种AI爬虫轮番“光顾”，资源被薅到见底……如何礼貌地拒绝这些不请自来的“访客”呢？这时， robots.txt 文件就可以派上用场了。什么是 robots.txt？robots.txt 是放置在网站根目录下的一个文本文件，用于向网络爬虫和机器人传达抓取规则。通过它，你可以指定哪些内容允许被抓取，哪些应被禁止访问。需要注意的是，尽管大多数正规机器人会遵守 robots.txt 中的规则，但某些恶意爬虫可能会无视这些限制，仍需结合其他防护手段。如何阻止特定爬虫？你可以在 robots.txt 中使用如下指令：BashUser-agent: [爬虫名称]Disallow: /针对常见AI机器人的屏蔽清单，以下是一份实用的 robots.txt 示例，可用于限制部分AI爬虫访问：BashUser-agent: AddSearchBotUser-agent: AI2BotUser-agent: Ai2Bot-DolmaUser-agent: aiHitBotUser-agent: AmazonBuyForMeUser-agent: atlassian-botUser-agent: amazon-kendra-User-agent: AmazonbotUser-agent: AndibotUser-agent: AnomuraUser-agent: anthropic-aiUser-agent: ApplebotUser-agent: Applebot-ExtendedUser-agent: AwarioUser-agent: bedrockbotUser-agent: bigsur.aiUser-agent: BravebotUser-agent: Brightbot 1.0User-agent: BuddyBotUser-agent: BytespiderUser-agent: CCBotUser-agent: ChatGPT AgentUser-agent: ChatGPT-UserUser-agent: Claude-SearchBotUser-agent: Claude-UserUser-agent: Claude-WebUser-agent: ClaudeBotUser-agent: Cloudflare-AutoRAGUser-agent: CloudVertexBotUser-agent: cohere-aiUser-agent: cohere-training-data-crawlerUser-agent: CotoyogiUser-agent: CrawlspaceUser-agent: Datenbank CrawlerUser-agent: DeepSeekBotUser-agent: DevinUser-agent: DiffbotUser-agent: DuckAssistBotUser-agent: Echobot BotUser-agent: EchoboxBotUser-agent: FacebookBotUser-agent: facebookexternalhitUser-agent: Factset_spyderbotUser-agent: FirecrawlAgentUser-agent: FriendlyCrawlerUser-agent: Gemini-Deep-ResearchUser-agent: Google-CloudVertexBotUser-agent: Google-ExtendedUser-agent: Google-FirebaseUser-agent: Google-NotebookLMUser-agent: GoogleAgent-MarinerUser-agent: GoogleOtherUser-agent: GoogleOther-ImageUser-agent: GoogleOther-VideoUser-agent: GPTBotUser-agent: iaskspider/2.0User-agent: IbouBotUser-agent: ICC-CrawlerUser-agent: ImagesiftBotUser-agent: img2datasetUser-agent: ISSCyberRiskCrawlerUser-agent: Kangaroo BotUser-agent: LinerBotUser-agent: Linguee BotUser-agent: meta-externalagentUser-agent: Meta-ExternalAgentUser-agent: meta-externalfetcherUser-agent: Meta-ExternalFetcherUser-agent: meta-webindexerUser-agent: MistralAI-UserUser-agent: MistralAI-User/1.0User-agent: MyCentralAIScraperBotUser-agent: netEstate Imprint CrawlerUser-agent: NovaActUser-agent: OAI-SearchBotUser-agent: omgiliUser-agent: omgilibotUser-agent: OpenAIUser-agent: OperatorUser-agent: PanguBotUser-agent: PanscientUser-agent: panscient.comUser-agent: Perplexity-UserUser-agent: PerplexityBotUser-agent: PetalBotUser-agent: PhindBotUser-agent: Poseidon Research CrawlerUser-agent: QualifiedBotUser-agent: QuillBotUser-agent: quillbot.comUser-agent: SBIntuitionsBotUser-agent: ScrapyUser-agent: SemrushBot-OCOBUser-agent: SemrushBot-SWAUser-agent: ShapBotUser-agent: Sidetrade indexer botUser-agent: TerraCottaUser-agent: ThinkbotUser-agent: TikTokSpiderUser-agent: TimpibotUser-agent: VelenPublicWebCrawlerUser-agent: WARDBotUser-agent: Webzio-ExtendedUser-agent: wpbotUser-agent: YaKUser-agent: YandexAdditionalUser-agent: YandexAdditionalBotUser-agent: YouBotDisallow: /使用方法将上述内容保存为 robots.txt 文件，上传至你的网站根目录即可生效。
