소유자 액세스 권한이 부여된 Google 클라우드 인스턴스 "ajc2"에 SSH를 통해 연결하려고 합니다. 이것은 내가 사용하는 명령입니다.
gcloud compute --project "clear-mountain-94802" ssh --zone "us-central1-c" "ajc2" --ssh-flag="-vvv"
나는 이미 "gcloud init" 및 "gcloud auth login"을 성공적으로 실행했습니다.
SSH 키가 성공적으로 생성되었으며 내 .ssh 폴더의 권한이 700으로 설정된 것 같습니다. 폴더 내의 모든 파일에는 최소 600 이상의 권한이 있습니다. 권한 거부됨(공개 키) 오류가 발생하는 이유를 잘 모르겠습니다. 누구든지 이것에 대한 통찰력을 가지고 있습니까?
serverfault가 SPAM이라고 생각하여 코드를 붙여넣을 수 없어서 해당 코드가 포함된 Google 그룹에 작성한 원본 게시물을 링크했습니다.https://groups.google.com/forum/#!topic/gce-discussion/ex8roHMubLY

답변1
올바른 사용자 이름을 사용하고 있습니까? 브라우저 창에서 SSH를 사용하여 Google 콘솔에서 연결해 보세요. 연결되자마자 whoami명령을 실행하여 사용자 이름이 무엇인지 확인하세요. 그런 다음 정확히 동일한 사용자 이름으로 SSH를 통해 연결을 시도하십시오. 다른 사용자 이름으로 시도하면 작동하지 않습니다. 로컬 Linux 시스템에서 실행하는 경우 아마도 Google Cloud의 Linux 시스템에 있는 사용자 이름과 다른 로컬 Linux 사용자와 연결을 시도할 것입니다.

다음 명령 사양에서 USER@INSTANCE를 확인하세요.
gcloud 계산 ssh [USER@]INSTANCE [--command=COMMAND] [--container=CONTAINER] [--dry-run] [--force-key-file-overwrite] [--internal-ip] [-- 일반] [--ssh-flag=SSH_FLAG] [--ssh-key-file=SSH_KEY_FILE] [--strict-host-key-checking=STRICT_HOST_KEY_CHECKING] [--zone=ZONE] [GCLOUD_WIDE_FLAG …] [-- SSH_ARGS …]
user@ajc2 대신 "인스턴스" 부분인 "ajc2"만 지정하고 'user'를 이 인스턴스에 대한 권한이 있는 Google 사용자 이름인 IOW, 올바른 사용자 이름으로 바꾸세요.
원래 명령: gcloud Compute --project "clear-mountain-94802" ssh --zone "us-central1-c" "ajc2" --ssh-flag="-vvv"
