对于开发testing，我需要设置一个SFTP服务器。 所以我想知道是否有可能使用相同的机器作为客户端和服务器。 我试过，我一直得到这个错误：
> Permission denied (publickey). > Connection closed 并通过运行ssh -v agharroud@localhost我得到：

关于这个问题的任何想法？ 谢谢 ！
是的，这是可能的，应该开箱即用（只要你有ssh和sshd ，看起来你是这样做的）。
没有看你的configuration，我会推测你的密码authentication被禁用，或者你的私钥有不正确的权限。 /home/agharroud/.ssh/id_rsa和/home/agharroud/.ssh/id_dsa应具有600权限（如果存在）。
