通过java的Powershell / Win32-Openssh ssh连接失败

时间：2016-05-04 13:58:56

标签： ssh openssl powershell-v2.0 ssh-keys openssh

我正在尝试从旧的ssh服务器（基于免费的ssh）迁移到新的Powershell / Win32-Openssh服务器。我已经下载了最新的测试版本，但我在客户端和服务器之间遇到了一些问题。首先我做了一些测试：

  • 从Windows控制台测试：工作正常。
  • 通过针对Powershell / Win32-Openssh服务器的应用程序进行测试：失败。
  • 通过针对旧ssh服务器的应用程序进行测试：Works。

有没有人遇到过这个问题，或者对如何解决这个问题有所了解？

环境：

  • 服务器端：Windows 2008 r2
  • 客户端：Windows 7 64位
  • Java Aplication使用“JSch - Java安全通道”创建ssh通道。
  • Sshd版本：Win32-OpenSSH（4_5_2016）

可以看出，服务器需要来自客户端的SSH2_MSG_KEX_ECDH_INIT（定义值为32）。然而，客户端发送的确切（2016-05-04 14：38：26,143 ERROR [stderr]（默认任务-69）INFO：SSH_MSG_KEX_ECDH_INIT发送）也值32.不要担心常量定义的名称，两者都有即使名称不同（SSH2_ * vs SSH _ *）

，值为32

我已跟踪所有通信，看起来没问题，但服务器认为客户端发送的信息存在问题....
