解决使用秘钥连接提示“Permissions 0755 for '/root/.ssh/id_rsa' are too open. ”问题

Published on 2014 / 12 / 16

直接复制个人的私钥到新的系统，结果远程的主机和git仓库都无法访问，提示

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@         WARNING: UNPROTECTED PRIVATE KEY FILE!          @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
Permissions 0755 for '/home/deepin/.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.
bad permissions: ignore key: /home/deepin/.ssh/id_rsa
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

私钥是正确的，看提示信息应该是权限设置的问题。
私钥的权限只能是700，执行下面命令修改之后就可以了：

1	chmod -R 700 ~/.ssh/*

.ssh 是我的私钥目录，-R递归改完全部的秘钥的权限。
