如何解决SSH 密钥:“'id_rsa.pub' 的 ermissions 0644 太开放”在 Mac 上
debug1: identity file /Users/tudouya/.ssh/vm/vm_id_rsa.pub type 1
看来您正在尝试使用错误的密钥文件。带有“.pub”扩展名的文件包含密钥的 公共 部分。没有“.pub”扩展名的相应文件包含密钥的 私有 部分。当您运行 ssh 客户端连接到远程服务器时,您必须向 ssh 客户端提供私钥文件。
您的.ssh/config
文件(或/etc/ssh_config
)中可能有一行如下所示:
IdentityFile .../.ssh/vm/vm_id_rsa.pub
您需要从文件名中删除“.pub”扩展名:
IdentityFile .../.ssh/vm/vm_id_rsa
解决方法
我在我的 mac 上生成了一个 ssh 密钥对并将公钥添加到我的 ubuntu 服务器(实际上,它是我 mac 上的虚拟机),但是当我尝试登录 ubuntu
服务器时,它说:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: UNPROTECTED PRIVATE KEY FILE! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
Permissions 0644 for '/Users/tudouya/.ssh/vm/vm_id_rsa.pub' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
bad permissions: ignore key: /Users/tudouya/.ssh/vm/vm_id_rsa.pub
Permission denied (publickey,password).
我尝试了很多方法来解决这个问题,更改密钥文件模式,更改文件夹模式,作为 stackoverflow 上的一些答案,但它不起作用。
密钥文件权限:
vm dir:
drwxr-xr-x 4 tudouya staff 136 4 29 10:37 vm
key file:
-rw------- 1 tudouya staff 1679 4 29 10:30 vm_id_rsa
-rw-r--r-- 1 tudouya staff 391 4 29 10:30 vm_id_rsa.pub
请给我一些想法… ==========================================
我将主机信息写入 ssh_config:
Host ubuntuvm
Hostname 10.211.55.17
PreferredAuthentications publickey
IdentityFile /Users/tudouya/.ssh/vm/vm_id_rsa.pub
我运行命令“ssh -v ubuntuvm”,它显示:
ssh -v ubuntuvm
