我在通过 ssh 隧道远程连接我的桌面时遇到了问题。
主机和客户机都是 Ubuntu 14.04。SSH 正在运行，高编号备用端口。X 转发有效。
我按照指示在这篇文章中设置 vino 服务器并使用 remmina。启动 remmina 连接时，它会挂起。最后我不得不取消。在远程主机上，连接的条目/var/log/auth.log如下：
Nov 18 08:54:49 Bear systemd-logind[31920]: New session 13 of user patton.
Nov 18 08:54:50 Bear sshd[12394]: error: connect_to bear.ddns.net port 5900: failed.
Nov 18 08:55:54 Bear sshd[12394]: channel_by_id: 0: bad id: channel free
Nov 18 08:55:54 Bear sshd[12394]: Disconnecting: Received ieof for nonexistent channel 0.
Nov 18 08:55:54 Bear sshd[12356]: pam_unix(sshd:session): session closed for user patton
有任何故障排除建议吗？我怎样才能让它工作？
编辑：根据 Letizia 的问题，关闭并重新启动远程主机上的 vino-server：这是输出：

答案1
解决了
链接的帖子没有提到这一点，我也没有想到在 Remmina 的 SSH 选项卡上选中“通过环回地址建立隧道”框。最后成功了。速度慢得可悲，但成功了。谢谢你的想法。
