I’m trying to connect to Linux using SharpSSH, but am unable to. I want to run some Linux commands from my .NET application.
Install Instructions:
SharpSsh – .NET library to connect to UNIX via SSH
– create account @ codeproject.com
– http://www.codeproject.com/Articles/11966/sharpSsh-A-Secure-Shell-SSH-library-for-NET (download demo project and binaries/dll files)
– copied into “SharpSsh” folder
I’m running the sharpSshTest console application that comes with this download. When I manually SSH (port 22) to Linux via Putty for same host/login/password, I’m able to connect fine. When connecting with the same host and credentials via .NET, I get an exception thrown in the Tamir.sharpSsh .NET library.
Unix distribution and version:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 5.0.9 (lenny)
Release: 5.0.9

Looks like that project is no good. Downloaded the new one here, which consists of the actual source code of the new “SharpSSH” class library project and a console application called “Examples” when you open the Visual Studio solution file.

When launching the “Examples” console application, it worked!
