.net - SharpSSH .NET 库 : unable to connect to Linux (Debian) from . NET

Question

我正在尝试使用 SharpSSH 连接到 Linux，但无法连接。我想从我的 .NET 应用程序运行一些 Linux 命令。

安装说明:

SharpSsh - 通过 SSH 连接到 UNIX 的 .NET 库
- 创建帐户@codeproject.com
- http://www.codeproject.com/Articles/11966/sharpSsh-A-Secure-Shell-SSH-library-for-NET (下载演示项目和二进制文件/dll 文件)
- 复制到“SharpSsh”文件夹

我正在运行此下载附带的 sharpSshTest 控制台应用程序。当我通过 Putty 使用相同的主机/登录名/密码手动 SSH(端口 22)到 Linux 时，我能够正常连接。通过 .NET 连接同一主机和凭据时，我在 Tamir.sharpSsh .NET 库中抛出异常。

Unix 发行版和版本:

$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 5.0.9 (lenny)
Release:        5.0.9
Codename:       lenny

堆栈跟踪:

   at Tamir.SharpSsh.jsch.Session.connect(Int32 connectTimeout)
   at Tamir.SharpSsh.jsch.Session.connect()
   at Tamir.SharpSsh.SshStream..ctor(String host, String username, String password)
   at sharpSshTest.sharpSshTest.SshStream() in C:\Source\{path}\selenium_references\sharpSsh_Demo\sharpSsh.demo\sharpSshTest.cs:line 76

sharpSshTest.cs 中的第 76 行:

SshStream ssh = new SshStream(host, user, pass);

e.Message 的值(value):

{"verify: False"}

下面是代码，如果有帮助的话:

看来那个项目不好。在这里下载了新的，它包含新的“SharpSSH”类库项目的实际源代码和打开 Visual Studio 解决方案文件时名为“Examples”的控制台应用程序。

启动“Examples”控制台应用程序时，它成功了!
