ssh chroot + putty = 해당 파일 또는 디렉토리 없음 8 15:03:45 NAS systemd[30398]: Reached

아무도 같은 문제가 있었습니까?

나는 sshd에 chroot를 설정하고 있었다 (OpenSSH_6.7p1 Debian-5 + deb8u3, OpenSSL 1.0.1t 2016 년 5 월 3 일; Debian Jessie)

결과적으로 WinScp는 성공적으로 로그인하고 퍼티는 다음과 같은 오류로 닫힙니다. 홈 디렉토리 / home / USER에 chdir 할 수 없습니다. 해당 파일이나 디렉토리가 없습니다.

그러나 chroot dir에 emty 디렉토리 / home / USER를 만들었습니다.

이것이 chroot를 만든 방법입니다.

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

sshd 설정 :

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

사용자:
