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:

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。

我看到一堆類似問題的人在過去曾與SFTP而且大部分是通過將頂線解決了時間缺少您的sshd_config

Subsystem  sftp  internal-sftp 
Match Group sftponly 
    ChrootDirectory /home/%u 
    ForceCommand internal-sftp 
    AllowTcpForwarding no 

此外,如果你打算要添加更多的用戶,建立一個像我的配置下面的sftp組可能是明智的。

但是,我把博客文章稍微回了一下,但是對於openssh-5。還包含一個骯髒但有效的交互式腳本,用於在幾秒鐘內建立一個新用戶。當新客戶加入時,一直使用它來工作。

希望這是一些幫助 - 如果不是,也許張貼你的/ var /日誌/安全這可能給你一個更好的擡起頭來,如果你的問題是基於許可。
