传文件，提示秘钥文件太开放，打印如下报错：

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@         WARNING: UNPROTECTED PRIVATE KEY FILE!          @

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Permissions 0755 for '/data/user/lxb/.ssh/id_rsa' are too open.

It is required that your private key files are NOT accessible by others.

This private key will be ignored.

Load key "/data/user/lxb/.ssh/id_rsa": bad permissions

rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]

rsync error: unexplained error (code 255) at io.c(235) [Receiver=3.1.2]

上述打印内容在提示你，赋予私钥文件的权限过大。

解决：$sudo chmod -R 700 /data/user/lxb/.ssh/

结束。
