WindowsコマンドプロンプトでGoogle CloudでホストされているFedora VMでSSHを実行することはできません。回答を見つけるためにWebを検索しようとしましたが、Windowsの説明/解決策が見つかりませんでした。
私は次の手順を実行しました。
- 下の図に示すように、Google Cloud に仮想マシンを作成しました。
fedora-cloud-base-gcp-34-1-2-x86-64
ファイアウォールのポート22を介して仮想マシンへのアクセスを許可します。
公開鍵と秘密鍵を生成するには、Windowsのコマンドプロンプトで次のコマンドを実行します。
ssh-keygen -t ECDSA
VMに公開鍵を追加します。
今私が走るときSSHユーザー名@ホスト.sshフォルダのコマンドプロンプトで次のエラーが発生します。
PS C:\Users\user1\.ssh> ssh -i C:/Users/user1/.ssh/id_ecdsa [email protected]
The authenticity of host '34.19.24.7 (34.19.24.7)' can't be established.
ECDSA key fingerprint is SHA256:3/NMD26H/bhz9DJYHssTcFAKEpttgpobGac.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '34.19.24.7' (ECDSA) to the list of known hosts.
[email protected]: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
興味深いことに、「Debian」イメージを使用して作成された同じサブネットの下の別の仮想マシンに接続できます。
この失敗の原因と解決策は何ですか？
