专家点评

上手难度：进阶更新于 2026-11-11

跨平台 RDP 协议栈，用来替换 Windows 自带的 mstsc，或作为库嵌入自有客户端

适用场景

  • 在 Linux/macOS 上连接 Windows 主机：xfreerdp 是原生客户端，不用装 Wine 或虚拟机，比 rdesktop 维护活跃得多
  • 把 RDP 能力嵌进自己的产品：Apache 许可 + 库形态，直接链 libfreerdp 做远程运维面板或云桌面客户端，不用自己啃协议文档
  • 把笔记本当第二屏（Linux 侧）：社区讨论里出现过这个用法，本质是拿 FreeRDP 当被控端/桥接，比专用投屏工具更可控
  • 多架构/嵌入式目标：README 明确列了 ARM、PPC、RISC-V 构建，在非 x86 设备上跑 RDP 客户端时可选面很窄

踩坑

  • 没有开箱即用的安装路径：README 只指向 wiki 编译说明，预编译包要去 pub.freerdp.com 单独找，发行版仓库里的版本往往落后不少，想用新特性就得自己编
  • 认证与传输的边角需求反复被提：issue 里 Kerberos 支持、UDP 传输、FIDO2/WebAuthn 虚拟通道这几类都拿到较高反应数，说明这些不是配置一下就能解决的，撞上就得改代码或等上游
  • 输入与显示适配不是默认就对：本地键盘布局、SDL 下的 rails（多显示器拼接）都有长期 open 的 issue，跨布局键盘或多屏非标准排列的环境要预留调试时间

同类对比

纯客户端场景且只要连 Windows，Remmina（Linux）或系统自带 mstsc（Windows）省事得多；要做协议层集成又不想碰 C，可以看 Go/Rust 生态的 RDP 绑定，但成熟度和虚拟通道覆盖不如 FreeRDP。

    New release with many user visible goodies for all of you. There have also been lots of issues addressed to harden against protocol violations/exploits, thanks to all the people doing in depth code reviews and security reports.

    • [proxy] add configuration options for /sec:ext or PROTOCOL_HYBRID_EX
    • [proxy] add configuration options for target certificate policy. NOTE: This changes default behavior from accept unless denied to deny unless accepted! Requires an update of your proxy configuration file if you rely on this.
    • [SDL,xfreerdp] seamless Entra/Azure integration on linux (with helper binaries)
    • [beta] Basic SDL client RAILS support for X11/wayland (other platforms currently lack some features / platform integration code, as we still need some native hooks)
    • [RDPECAM] stops camera streams now when the remote no longer requests frames. (no more camera LED after closing the windows application accessing it)
    • [RDPEWA] support user verification in addition to / instead of pin
    • [RDPEUSB] properly map interface index to interface numbers (more devices should work now)
    • [android] updated touch pointer
    • [wlfreerdp] shortcut inhibit release on mouse leave window
    • [xfreerdp] rails improvements, hopefully no longer shrinking windows
    • Full support for [MS-RDPBCGR] 2.2.10.2 Early User Authorization Result PDU, so now you get a error message if a user is not allowed to log in instead of a network failed message. (Authentication /sec:ext or PROTOCOL_HYBRID_EX)
    • [shadow] add configuration options for /sec:ext or PROTOCOL_HYBRID_EX
    • [gateway] split HTTP timeout from TCP connect timeout
    • [ffmpeg] support generic hardware accelerated encoding/decoding, replacing the old VAAPI only implementation. (still experimental as there are often driver issues)

    CVE

    Note: Advisories will be published days/weeks after the release, so links are 404 until then.
