I had a problem with my mac where I couldn't save any kind of file on the disk anymore. 我的Mac出现问题，无法再在磁盘上保存任何类型的文件。 I had to reboot OSX lion and reset the permissions on files and acls. 我必须重新启动OSX Lion并重置文件和ACL的权限。
But now when I want to commit a repository I get the following error from ssh: 但是现在当我要提交存储库时，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.
What permissions levels should i give to the id_rsa file? 我应该赋予id_rsa文件什么权限级别？
