我在Mac上生成一个ssh密钥对,并将公钥添加到我的ubuntu服务器(实际上,这是我的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).
我已经尝试了多种方法来解决此问题,更改密钥文件模式,更改文件夹模式,作为关于stackoverflow的一些答案,但是它不起作用。
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

在ssh命令中添加用于连接时,我会遇到此问题。似乎强制在ssh命令部队上使用一些公钥要求输入密码(即使密码短语为空,至少在我的情况下也是如此)
