私は運がなくてその問題を解決するためにインターネットを見つけた別の解決策に疲れました:
/etc/ssh/
のキーの正しいアクセス許可、プライベートRSAキーの場合は400、パブリックRSAキーの場合は600。/home/usersrv/.ssh/
フォルダーの場合は700。 authorized_keys
は存在しません。後で許可600で作成しました。ファイルはまだ空ですが、中に何かをコピーすることになっていますか?ホームディレクトリは、システムと同じボリューム上にあります。サーバー構成/etc/ssh/sshd_config
uncommented part:
Port 2222
AddressFamily any
ListenAddress 0.0.0.0
ListenAddress ::
HostKey /etc/ssh/ssh_Host_rsa_key
PermitRootLogin no
RSAAuthentication yes
PubkeyAuthentication yes
# To disable tunneled clear text passwords, change to no here!
PasswordAuthentication no
PermitEmptyPasswords no
# Change to yes to enable challenge-response passwords (beware issues with# some PAM modules and threads)
ChallengeResponseAuthentication no
KerberosAuthentication no
GSSAPIAuthentication no
UsePAM yes
X11Forwarding yes
X11UseLocalhost yes
PermitTTY yes
PrintMotd no
Win + PuTTYから接続しようとすると、エラーメッセージが表示されます:サポートされている認証方法がありません(サーバーが公開鍵を送信しました)

誰かが同じ問題を抱えていたり、解決策を知っていますか?敬具。
コンピューターの公開鍵をサーバーに追加しなかったようです。クライアントコンピューターからの公開鍵はauthorized_keysファイルに保存されます。
/ etc/ssh/sshd_configのこの行をyesに変更します(後で再び元に戻すことができます)
PasswordAuthentication yes
そして、sshデーモンを再起動します
Sudo service ssh restart
次に、クライアントコンピューターから次のコマンドを発行して、公開鍵をサーバーにエクスポートします。
ssh-copy-id usersrv@server
コマンドプロンプトで、パスワードを入力します。その後、sshキーを介してサーバーにアクセスできるようになります。
