使用SSHJ連接到Google Compute Engine實例

我在Google Compute Engine中創建了一個實例，我需要使用SSHJ進行連接，但我沒有收到。我可以使用AWS成功連接：使用SSHJ連接到Google Compute Engine實例

public String exec(String host, String keyPair, String script) throws IOException{ 
    File keyPairFile = new File(keyPair); 
    SSHClient ssh = new SSHClient(); 
    ssh.addHostKeyVerifier(new PromiscuousVerifier()); 
    ssh.connect(host); 

    PKCS8KeyFile keyFile = new PKCS8KeyFile(); 
    keyFile.init(keyPairFile); 
    ssh.auth(USER_DEFAULT, new AuthPublickey(keyFile)); 

    Session session = null; 
    try { 
     logger.info("Conectando via ssh " + host + "..."); 
     session = ssh.startSession(); 
     final Command command = session.exec(script); 
     String response = IOUtils.readFully(command.getInputStream()).toString(); 
     command.join(10, TimeUnit.SECONDS); 
     return response; 
    } finally { 
     session.close(); 
     ssh.disconnect(); 
     ssh.close(); 
    } 
}

Google Compute Engine要做什麼？

我使用puttygen創建了一個公鑰和一個私鑰。然後我訪問了我的Google Compute Engine的控制檯並導入了公鑰。這樣我可以使用私鑰訪問膩子。

當嘗試使用上面定義的exec方法SSHJ訪問，發生錯誤：

任何建議？

你得到的錯誤是什麼？ –

我對參數「keyPair」有疑問。對於AWS雲，我使用我的keyPair文件（.pem）的方式下載AWS控制檯。已經在Google Computer Engine上，我正在使用jclouds創建實例，並且他已經創建了一個用戶「jclouds」和ssh-rsa密鑰。我應該將ssh-rsa密鑰下載到本地機器上？如何做這個程序？ –

PuTTY .ppk密鑰不是PKCS#8格式。您的代碼正嘗試讀取PKCS#8密鑰對。嘗試將您的私鑰轉換爲PKCS#8，或者在您的代碼中使用不同的密鑰格式/方法，從SSHJ key provider list。
