SFTP 连接失败

SFTP 连接失败

我想配置用户FTP用户使用 sftp 获取现有的 apache 拥有的目录/var/www/网站

我将其添加为新用户并/var/www/网站它的主目录,

useradd -md /var/www/website -s /bin/bash ftpuser

sshd_配置

Subsystem sftp internal-sftp

Match User ftpuser
    ChrootDirectory /var/www/website
    X11Forwarding no
    AllowTcpForwarding no
    ForceCommand internal-sftp

该目录现在归,并具有 acl 权限www-数据用户:

# ls -ltr
   drwxrwx---+  5 root     root     4096 Nov  8  2012 website

# getfacl website/
   # file: website/
   # owner: root
   # group: root
   user::rwx
   user:www-data:rwx
   group::rwx
   group:www-data:rwx

但每当我尝试连接 SFTP 时,都会出现以下调试错误:

ftpuser@ftp_server's password:

debug2: we sent a password packet, wait for reply

有什么想法可以解决该问题吗?

编辑:

/var/log/authz

fatal: bad ownership or modes for chroot directory component "/var/www/"

答案1

使用ChrootDirectory选项sshd_config需要对书面文本有一些基本的了解。

这是手册页的快照sshd_config(5)

Chroot目录

chroot(2)指定认证后 目录的路径名。路径名的所有组成部分都必须是 root 拥有的目录,且其他任何用户或组都无法写入。chroot 之后,sshd(8)将工作目录更改为用户的主目录。

这是您的错误日志:

fatal: bad ownership or modes for chroot directory component "/var/www/"

当您将一加一时,您就会明白,这不仅/var/www/webiste需要由 root 拥有,而且还需要/var/www/var目录拥有,正如这里多次提到的那样。
