我与我的 Raspberry Pi 一起vnc
使用。ssh
一段时间以来它运行良好,但在遵循之后这些说明openvpn
在运行 Raspbian 操作系统的 Raspberry Pi 上进行设置。我发现我无法再访问Raspberry Pi上的VNC服务器。
转发 x11ssh
正在工作,但显然,vnc server
无法访问其端口,因此甚至无法启动。

以下是一些可能有用的其他信息:

这似乎可能与 ip6 的更改iptables
或禁用有关/etc/sysctl.conf
,但我不知道如何解决它。任何想法,将不胜感激。
答案1
Jan 21 14:25:11 raspberrypi vncserver-x11[8898]: TcpListenerManager: not accepting connections: failed to listen on at least one address.
Jan 21 14:25:11 raspberrypi vncserver-x11[8898]: TcpListenerManager: not listening on [::1]::5900: bind: Cannot assign requested address (99)
::1
是 IPv6 的等价物127.0.0.1
。因此,如果您禁用了 IPv6,那么是的,收听::1
变得不可能。
您有两个选择:
- 首先,就我而言,建议是重新启用 IPv6。在现代世界中,没有真正的理由要禁用 IPv6(事实上,几年后您可能无法在没有 IPv6 的情况下访问互联网),而且它可能会导致更多问题,而不仅仅是这个问题
- 配置
vncserver-x11
以使其不再尝试侦听::1
或任何其他 IPv6 地址(::
最有可能的其他候选地址)。
这vncserver-x11-serviced
似乎是 RealVNC 特有的,我找不到任何解释如何为其配置侦听地址的文档,因此您可能必须自己弄清楚最后一点。
答案2
Jan 21 14:25:11 raspberrypi vncserver-x11[8898]: TcpListenerManager: not accepting connections: failed to listen on at least one address.
Jan 21 14:25:11 raspberrypi vncserver-x11[8898]: TcpListenerManager: not listening on [::1]::5900: bind: Cannot assign requested address (99)
监听地址无效。端口与地址之间应使用单个分隔符:
,而不是::
在 IPv6 地址中用作缩写的双分隔符。
无论您在何处配置[::1]::5900
,请更改为[::1]:5900
答案3
我禁用了 ipv6,并且在 RealVnc 中看到了同样的问题,通过使用修复 -IpListenAddresses=0.0.0.0
确保-localhost
从参数中删除
这是参数详细信息
IpListenAddresses - 以逗号分隔的 IP 地址列表,用于侦听 TCP/UDP 连接,或者为空以侦听所有可用 IP 地址。请注意,如果 localhost 参数设置为 True,则忽略此参数。 (默认=)
