以下のコードを使用してSFTPサーバーとの接続を確立しようとしていますが、JavaのJschを使用してsftpサーバーに接続しようとするとアルゴリズムのネゴシエーションが失敗する

情報 - 以下のバージョンを使用しています

  • Javaバージョン "1.8.0_101"
  • のJava（TM）SEランタイム環境（ビルド1.8.0_101-B13）
  • JSC H - 0.1.54
  • JUnitの - 期待

    JSch jsch = new JSch(); 

Properties configuration = new Properties(); 
configuration.put("cipher.s2c", 
        "aes128-ctr,aes128-cbc,3des-ctr,3des-cbc,blowfish-cbc,aes192-ctr,aes192-cbc,aes256-ctr,aes256-cbc"); 
configuration.put("cipher.c2s", 
        "aes128-ctr,aes128-cbc,3des-ctr,3des-cbc,blowfish-cbc,aes192-ctr,aes192-cbc,aes256-ctr,aes256-cbc"); 
configuration.put("kex", "diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group-exchange-sha256"); 

Session session = jsch.getSession(user , host, port); 
session.setPassword(pwd); 
session.setConfig(configuration); 

System.out.println("------------------>Establishing Connection..."); 
session.connect(); 
System.out.println("------------------>Connection established."); 
System.out.println("------------------>Creating SFTP Channel."); 
ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp"); 
sftpChannel.connect(); 
System.out.println("------------------>SFTP Channel created.");

    - - 4.12

以下のコードを使用してい接続サーバ

    に正常になされるべきです
  • 注 -私はすべての設定を含めてみましたイオンの方法はここでは他のさまざまな記事に記載されていたが、何も働かなかった。
