我正在尝试使用密码通过 sftp 进入 Amazon Linux 系统。
我创建了一个帐户“amitd”，设置了密码，并且修改了 /etc/ssh/sshd_config 以设置“PasswordAuthentication yes”，然后我退出了 sshd。
我尝试通过 ssh 和 sftp 登录，没有问题，一切看起来都很好。
但是，我希望该帐户仅用于 sftp，因此我再次编辑 /etc/ssh/sshd_config，并添加：
Match User amitd
ChrootDirectory /disk1/%u
ForceCommand internal-sftp
X11Forwarding no
我创建了“/disk1/amitd”并确保它归 amitd 所有，然后再次重新启动 sshd 服务器。
现在，我尝试使用 ssh 登录，并得到：
mjb@feynmann:~/PEMs_and_PPKs$ ssh [email protected]
[email protected]'s password:
Connection to 172.24.5.159 closed by remote host.
Connection to 172.24.5.159 closed.
这很好，这也是意料之中的。
当我尝试使用 sftp 登录时，我得到：
mjb@feynmann:~/PEMs_and_PPKs$ sftp [email protected]
[email protected]'s password:
Connection to 172.24.5.159 closed by remote host.
Connection closed.
Connection closed
这对我来说毫无意义。
如果我这样做：
ssh -vvv [email protected]
我得到：
<...omitted all logging before the password prompt...>

帮忙？有人能给我提供线索吗？
编辑：添加信息：我尝试明确启用 internal-sftp，但仍然无法登录。C 传递 /etc/ssh/sshd_config：
#Subsystem sftp /usr/libexec/openssh/sftp-server
Subsystem sftp internal-sftp
退回 sshd，但仍然有错误：
