들어가며
최근에 집에 안 쓰는 Desktop을 Ubuntu Server로 만들었다.
그래서 그 Server에 SSH로 접속해서 작업을 할 수 있도록 세팅을 해 놓았다.
그런데 내 laptop vscode에서 ssh로 접속하려니 다음과 같은 에러가 나왔다.
> @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
> @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

지금 다시 새로 깔린 Ubuntu OS에 접속하려 하니, 전에 있던 인증 정보로 Server에 login하려니 충돌이 난 것 같다.
그래서 상기 파일 내용을 모두 날리고, 다시 vscode에서 접속하니 잘 됐다. (쑻)
