켈프에더 올렸던 글인데 여기도 포워딩 해봅니다 .

다른 장소에 팔아먹은 임베디드 장비가 내부 아이피를 사용하고 그 장소에 특정 서버를 설치할 여력이 없기에 생각해낸것이
ssh reserve tunnel 이였습니다. 그런데 이짓을 할려면 ssh 는 물론이고 타켓에 sshd까지 올려야 한답니다.

ssh 는 잘 됐는데 -_-;; sshd 올리는게 문제네요.. 컴파일이야 잘 된거 같은데.. 대략 환경 설정으로 난감하네요 OTL.

음 그런데 무엇이 문제인지 로긴 성공 이후 바로 커넥션이 끊어져 버리네요 -_-;

무슨 환경 설정이 부족한건지 도무지 알 길이 없습니다 OTL..

혹시 무엇인지 아시는 분은 내공좀 나누어 주세요

이것만 마무리 되면 ssh reserve tunnel 이 완성되는데 아흐.. 쩝쩝쩝.
