我在 freebsd vps 上使用 ssh 密钥时遇到问题。我生成了一个密钥，它在 debian 上有效。我通常只需将其复制粘贴到，~/.ssh/authorized_keys它就可以开始工作。在 freebsd 中却不行。我尝试将其输入，但~/.ssh/authorized_keys2仍然没有响铃。我的密钥有密码。所以当我登录 osx 密码窗口弹出窗口输入密码时，我按下确定后它显示ident added to id_rsa，然后 ssh 仍然在 shell 中要求输入密码。
我的笔记本电脑是 osx lion。可以运行的服务器是 debian 6 squeeze 服务器，无法运行 freebsd8.2

问题解决了：
看来当我复制公钥时，每个空格后面都以某种方式添加了空格。当我删除它们时，一切正常。感谢 natxo_asenjo 提供的提示
