oneko：错误并退出

  • 772

我正在开发运行 Raspbian GNU/Linux 10 (buster) 的 Raspberry Pi Zero W。其他 X11 应用程序，如xlogo、xclock、xosview，甚至xeyes运行得很好，但我没有运气运行oneko。

pi@nalzoks-pi:~ $ oneko
Display not supported shape extension.
oneko: Error and exit.
BadAccess (attempt to access private resource denied)
pi@nalzoks-pi:~ $ oneko -noshape
oneko: Error and exit.
BadAccess (attempt to access private resource denied)
pi@nalzoks-pi:~ $ sudo oneko
sudo: oneko: command not found

我在本地网络中通过 SSH 访问 Pi 并使用 X11 转发。

任何想法？

ssh

  1. Best Answer

    当您通过 ssh 从 Mac 登录到 Pi 时，客户端程序 (oneko) 在 Pi 上运行，并联系在 Mac 上运行的 X 服务器。

    我刚刚通过从我的 MacBook 登录到我的 Debian PC 来尝试这个ssh，并且oneko运行良好，当我这样做时xdpyinfo，我看到的扩展数量与我xdpyinfo直接在我的 Mac 上看到的一样。

    但是，在您的情况下，转发的连接完全不同：

    number of extensions:    2
  BIG-REQUESTS
  XC-MISC

    这是很少扩展的方式，特别是没有形状。所以现在的问题是为什么会发生这种情况。

    我看到您有两个 X 转发登录（sshd 在 6010 和 6011 上都监听）。当您只使用一次登录时会发生什么？

    编辑

    要将评论的结果添加到答案中：有必要使用 ssh 和可信转发（即ssh -Y，而不是ssh -X）以使所有扩展可用。
