sftp 连接挂载到一个文件夹中，但是出现了错误。
~$ sshfs admin@example.com:/ testfo
remote host has disconnected
localhost 重复执行该命令，就会出现相同的错误。这条命令在另一台机器上也可以运行，所以问题肯定出在服务器上。
~$ cat /var/log/auth.log

由于我在调试类似问题时发现，~/.ssh目录的所有者是管理员。
供将来参考的附加信息：
问题并不在于SSH本身，而是在于SFTP。这表现为SSH连接正常工作，但SFTP始终失败。尝试进行SFTP会导致Received unexpected end-of-file from SFTP server。
问题与登录脚本输出的字符串（例如~/.bashrc）无关。
该问题存在于所有用户（包括root）。
