ssh chroot + putty = không có tập tin hoặc thư mục như vậy

có ai có cùng một vấn đề?

Tôi đã cài đặt chroot cho sshd (OpenSSH_6.7p1 Debian-5 + deb8u3, OpenSSL 1.0.1t ngày 3 tháng 5 năm 2016; Debian Jessie)

Kết quả là WinScp đăng nhập thành công và putty đóng với lỗi: không thể chdir vào thư mục chính / home / USER không có tệp hoặc thư mục đó.

Tuy nhiên tôi đã tạo thư mục emty / home / USER trong chroot dir.

Đó là cách tôi đã tạo ra chroot:

mkdir -p /DataVolume/USER/{dev,etc,lib,usr,bin} 
mkdir -p /DataVolume/USER/usr/bin 
mknod -m 666 /DataVolume/USER/dev/null c 1 3 
cd /DataVolume/USER/etc 
cp /etc/ld.so.cache . 
cp /etc/ld.so.conf . 
cp /etc/nsswitch.conf . 
cp /etc/hosts . 
cd /DataVolume/USER/usr/bin 
cp /bin/ls . 
cp /bin/bash . 
cd /sbin 
wget -O l2chroot http://www.cyberciti.biz/files/lighttpd/l2chroot.txt 
chmod +x l2chroot  
chown root: /DataVolume/USER && 
chmod 755 /DataVolume/USER 
mkdir -p /home/USER 
mount -o bind /DataVolume/USER /home/USER

cấu hình sshd:

Subsystem sftp internal-sftp -f AUTH -l VERBOSE 
Match user USER 
  ChrootDirectory %h 
  ForceCommand internal-sftp 
  AllowTcpForwarding no 
  PermitTunnel no 
  AllowAgentForwarding no 
  X11Forwarding no
