확인해야 할것.

1. jsch 라이브러리 버전을 최신버전인 0.1.54를 사용했었는데.. 0.1.42 버전으로 낮춰서 사용

2. sftp 접속 정보를 정확히 확인해봐야함

etc. 필자는 spring-boot를 사용하는데, properties가 개발용하고 상용이 있어 톰캣에서 올릴때 뭔가 꼬여서 올라가 났던 에러로 추정

3. /etc/ssh/sshd_config 에서 경로 확인 및 틀리다면 수정
# override default of no subsystems 
Subsystem sftp /usr/libexec/openssh/sftp-server
