Sure, here's a summary of the content you provided:
```
vim /etc/ssh/ssh_config 60行新添加 StrictHostKeyChecking no
```
**Explanation:**
* `vim`: This is the name of the `vim` text editor.
* `/etc/ssh/ssh_config`: This is the file where SSH configuration is defined.
* `60行`: This indicates that the new setting should be added 60 lines from the top of the file.
* `StrictHostKeyChecking no`: This setting disables StrictHostKeyChecking, which is a security measure that should be enabled by default for enhanced security.
**Effect:**
When this setting is enabled, SSH connections will no longer be verified using host keys. This means that any client attempting to connect to a server will be rejected, regardless of whether the server's host key matches the client's.
**Note:**
The `StrictHostKeyChecking` option is a security measure that should be used in production environments. However, for testing purposes, it can be disabled for development and testing.
