JSch 0.1.53 session.connect（）拋出「IO流讀取結束」

2016-05-17 162 views

我下載了一個新的JSch 0.1.53 library並且JSch（sftp）下載任務不再起作用。 session.connect()函數拋出錯誤Session.connect: java.io.IOException: End of IO Stream Read失敗。JSch 0.1.53 session.connect（）拋出「IO流讀取結束」

我的老jsch.jar（2011-10-06）對同一個主機正常工作，也許我缺少一個新的配置道具？

Session session=null; 
ChannelSftp channel=null; 
try { 
    JSch.setLogger(SSHUtil.createJschLogger()); 

    JSch jsch=new JSch(); 
    session=jsch.getSession("myuser", "11.22.33.44", 22); 
    session.setConfig("StrictHostKeyChecking", "no"); 
    session.setPassword("mypwd"); 
    session.connect(2000); // <-- FAILS HERE 
    channel = (ChannelSftp)session.openChannel("sftp"); 
    channel.connect(2000); 
    ...

這是一個廣泛的JSch日誌記錄，指示發生了什麼。

我也有一個很老的Jsch.jar（2011-10-06）其中下載任務工作得很好，這是一個日誌。我想升級的原因是傳輸文件非常慢。新版本應該更好地完成我已閱讀的內容。

編輯 我靈機一動，後臺階在Maven repository版本，實際上正是這種不正常很新的版本。以前的jsch-0.1.52.jar發佈工作正常。我試圖聯繫圖書館開發人員。

這是一個工作的0.1.52版本的日誌。

你可能會得到通過與服務器斷開連接。服務器日誌說什麼？ –

好點，新增0.1.52日誌，新（失敗）版本是0.1.53.jar文件。日誌轉儲在開始時打印庫版本。 – Whome

不要使用'StrictHostKeyChecking = no'，這樣做就會失去對MITM攻擊的保護。 –

的JSch 0.1.53支持（和喜歡）的diffie-hellman-group-exchange-sha256 KEX，什麼服務器聲稱支持過，所以JSch嘗試使用它。

由於某種原因服務器斷開連接後。

要解決的是，強制JSch使用diffie-hellman-group1-sha1 KEX，什麼JSch 0.1.52喜歡：

session.setConfig("kex", "diffie-hellman-group1-sha1");

這樣做的竅門，我也可以比舊的0.44庫更快地確認0.53下載文件。 – Whome

在JetBrains PyCharm IDE環境中使用JSch時，有沒有辦法設置這個「kex」值？我遇到了相同的問題，但我只相信某些CentOS 7服務器，而不是其他人，如果可能的話我想測試這個解決方法。 –

@MarkEdington如果您還有其他問題，請提問。這是問答網站，不是論壇。 –

我有同樣的問題，我只是改變了jsch版本0.1.54，並得到有效解決

添加到您的pom.xml

<dependency> 
    <groupId>com.jcraft</groupId> 
    <artifactId>jsch</artifactId> 
    <version>0.1.54</version> 
</dependency>

我也面臨與0.1.54版本相同的問題。（「IO流讀取結束」） –

檢查更高的版本。 @sharathchandra –
