WSO2 ESB：SFTP 文件傳輸：無法連接到 SFTP 服務器

Question

我正在嘗試使用 WSO2 Enterprise Integrator 6.3.0 將一些文件從本地服務器傳輸到 SFTP 服務器。 我有用戶名、SFTP 位置、SFTP 端口（990）、ppk 文件和密碼短語。 當我在代理服務中嘗試以下配置時，我無法連接到 SFTP 服務器。 它給出了 com.jcraft.jsch.JSchException: Auth fail 錯誤。 使用膩子，連接有效。

<?xml version="1.0" encoding="UTF-8"?>
<proxy name="SFTPFileTransferProxy" startOnLoad="true"
  trace="disable" transports="vfs" xmlns="http://ws.apache.org/ns/synapse">

        scope="default" type="STRING"/>
      <log level="custom">
        <property expression="$ctx:FILE_NAME" name="FL2"/>
        <property name="sequence" value="FTPProxy"/>
      </log>
    </inSequence>
    <outSequence/>

  <parameter name="transport.vfs.SFTPIdentityPassPhrase">KEY_PASSPHRASE</parameter>
</proxy>

我得到的錯誤是

如何使用 SFTPIdentities 連接 SFTP 服務器？

Answer 1

在 Windows 上嘗試如下鍵路徑。 這個對我有用。

<parameter name="transport.vfs.SFTPIdentities">/sftp/keys/PrivateKey_Integration.ppk</parameter>

在 Ubuntu 上，我給出的關鍵路徑為

<parameter name="transport.vfs.SFTPIdentities">/home/sbhatti/.ssh/key.ppk</parameter>

但它不起作用，並給出與上述問題相同的異常。 任何人有任何想法？ 我們如何調試和應用正確的路徑？
