📰 Ubuntu Snap Prompting Improvements If you haven’t tried Ubuntu’s ‘Permission Prompting’ feature for a while, there’s more reason to do so in the latest release. Canonical’s Oliver Calder has shared an update on recent improvements to the security feature, which sets out to “empower users” by letting them decide what software can access on the rest of the system at runtime rather than retrospectively. 🔗 Source: https://www.omgubuntu.co.uk/2026/05/ubuntu-snap-prompting-client-improved #ubuntu

vibe coding 了个端口敲门工具,欢迎体验 knock-proxy 是一个端口敲门 TCP 转发工具。服务端用防火墙默认 DROP 公网 TCP 端口;客户端先发送 knock ,服务端验证后临时放行来源 IP ,然后客户端连接同一 TCP 端口,完成 HMAC-SHA256 二次认证并转发到本机 upstream 。 适合隐藏 SSH 、RDP 、数据库管理端口、Web 管理后台等 TCP 服务。 项目地址 <https://github.com/ming79486/knock-proxy> via V2EX 分享创造 标签: #端口#TCP#knock ⚡️探索号频道 ⚡️探索者频道 ⚡️探索者交流群 ⚡️ Youtube 频道:科技探索者 每天推荐有趣内容,欢迎订阅、转发。
