我正在嘗試使用適合PCI的chroot。我希望一些用戶只能通過sftp連接,而不能通過ftp連接(我可以很容易地限制)。不過,我需要將sftp用戶chrooted,以便他們可以遍歷dir樹並查看所有內容。chroot不能在openssh上工作6.2
我將此添加到我的OpenSSH ssd_config文件來測試一個用戶第一:
Match User dbl
ChrootDirectory %h
AllowTCPForwarding no
X11Forwarding no
ForceCommand internal-sftp
當我嘗試連接,我得到這樣的輸出:
$ sftp -v [email protected]

正如你所看到的,後右我輸入它讓我進入的密碼,然後立即關閉連接。它甚至不會像應該那樣提示sftp提示符。我在這裏嘗試了幾個其他帖子,似乎有關,但沒有得到任何地方。
每個用戶都有/ bin/sh作爲他們的shell。
