나는 오후 내내이 문제에 갇혀 있었고 무슨 일이 일어나고 있는지 모른다. sftp 명령을 사용해야하는 이유는 쉘 스크립트에서 사용하기 때문입니다. SFTP를 사용하여 파일을 다운로드 할 수있는 CentOS 7과 함께 사용할 수있는 다른 프로그램이 있다면 저를 밝히십시오.

사용 된 SFTP 클라이언트 : WinSCP 및 PSFTP.
동일한 네트워크와 인터넷에서 실행되는 서로 다른 컴퓨터에서 테스트했습니다 (여기서는 IP 주소 만 사용됨). 동일한 컴퓨터 (localhost 및 루프백 주소 사용)에서 예상대로 작동합니다.
방화벽 서비스가 중지되었으며 프록시가 사용 중이거나 구성되지 않았습니다.
내가 얻는 오류는 (sftp -vvv sftp @ hostname 사용)입니다.

# This is the sshd server system-wide configuration file. See

# This sshd was compiled with PATH=/usr/local/bin:/usr/bin
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the
# default value.

사용자를 만드는 데 사용되는 코드 :
mkdir -p /home/sftp
chown root /home/sftp
chmod 755 -R /home/sftp
useradd -d /home/sftp -r sftp
usermod -s /sbin/nologin sftp
echo "password" | passwd --stdin sftp
클라이언트에서 sshd_config 파일을 건드리지 않았으므로 설치의 기본값이라고 생각합니다 (구현에서는 구성 파일을 변경할 수 없음).
