linux端口连接错误

I have set up X desktop and want to connect to the X server through ssh. As you know ssh provides X forwarding which is a very useful feature and used a lot of system administrators.

我已经设置了X桌面，并希望通过ssh连接到X服务器。 如您所知，ssh提供了X转发功能，这是非常有用的功能，并且使用了很多系统管理员。

尝试连接Ssh X转发 (Try To Connect Ssh X Forwarding)

We will try to connect the X service of remote ssh server by providing -X parameter.

我们将尝试通过提供-X参数来连接远程ssh服务器的X服务。

$ ssh -X ubu1

OR

要么

$ nautilus

We get an error like “Unable to init server: Could not connect: Connection refused” or  “/usr/bin/xauth:  /home/ismail/.Xauthority not writable, changes will be ignored”

我们收到类似“无法启动服务器：无法连接：连接被拒绝”或“ /usr/bin/xauth：/home/ismail/.Xauthority不可写，更改将被忽略”的错误

更改Xauthority的所有权(Change Ownership Of Xauthority)

We will change Xauthority file ownership because it will be used by the current user to read and write.

我们将更改Xauthority文件的所有权，因为当前用户将使用它来读写。

$ sudo chown ismail:ismail .Xauthority

检查磁盘是否已满(Check Disk If It Is Full)

One of the root cause of a lot of problems is fulling disk. It is a hidden problem and generally does not show himself. We should all ways count this option for troubleshooting.

许多问题的根本原因之一是磁盘已满。 这是一个隐藏的问题，通常不会显示自己。 我们应该通过各种方式将此选项用于故障排除。

$ df -lh

As we can see in the third line of output our root path have enough free space to run X

正如我们在输出的第三行中看到的那样，我们的根路径具有足够的可用空间来运行X

检查Ssh Server X转发设置 (Check Ssh Server X Forwarding Setting)

The ssh server configuration has a line X11Forwarding which enables or disable X11 forwarding. It may be disabled because of security reasons.

ssh服务器配置具有X11Forwarding行，该行启用或禁用X11转发。 由于安全原因，它可能被禁用。

$ cat /etc/ssh/sshd_config  | grep X11Forwarding

检查Ssh客户端ForwardX11设置(Check Ssh Client ForwardX11 Setting)

The client-side of the ssh configuration also includes X11 forwarding. It shouldn’t be disabled or explicitly enabled like below.

ssh配置的客户端还包括X11转发。 不应禁用或明确启用它，如下所示。

$ cat /etc/ssh/ssh_config | grep ForwardX11

We should uncomment line ForwardX11 no and change to yes.

我们应该取消注释ForwardX11行，并更改为是。
