我的 Mac 出现问题，无法再在磁盘上保存任何类型的文件。我不得不重新启动 OSX lion 并重置文件和 acls 的权限。
但是现在当我想提交一个存储库时，我从 ssh 收到以下错误：
Permissions 0777 for '/Users/username/.ssh/id_rsa' are too open. It is recommended that your private key files are NOT accessible by others. This private key will be ignored.
我应该给 id_rsa 文件什么权限级别？
密钥只能由您读取：
chmod 400 ~/.ssh/id_rsa
如果您需要对 Key 进行读写：
chmod 600 ~/.ssh/id_rsa
600似乎也很好（实际上在大多数情况下更好，因为您以后不需要更改文件权限来编辑它）。
手册页中的相关部分 ( man ssh)
man ssh
``` ~/.ssh/id_rsa Contains the private key for authentication. These files contain sensitive data and should be readable by the user but not accessible by others (read/write/execute). ssh will simply ignore a private key file if it is accessible by others. It is possible to specify a passphrase when generating the key which will be used to encrypt the sensitive part of this file using 3DES. ~/.ssh/identity.pub ~/.ssh/id_dsa.pub ~/.ssh/id_ecdsa.pub ~/.ssh/id_rsa.pub Contains the public key for authentication. These files are not sensitive and can (but need not) be readable by anyone. ```
