我正在尝试将新添加的用户限制到他的主目录 /home/username。不希望他能够从中 cd 出来。
我的 sshd_config 如下:
Match User username
ChrootDirectory %h
X11Forwarding no
AllowTcpForwarding no
ForceCommand internal-sftp
我使用 chown 将 /home/username 目录的所有者设置为 root,并将权限设置为 755。
还将用户添加到 chroot.conf。
重新启动 sshd。但是当我尝试以用户身份登录时,远程服务器关闭了连接。

知道为什么会发生这种情况吗?
答案1
是的。您已强制他仅使用 sftp 协议进行连接ForceCommand internal-sftp
。不出所料,这意味着他无法通过 ssh 进入。
