asp.net c# connecting to putty ssh and running a command line like status

Question

ok folks i have seen alot of questions about this but none that i can use or understand

What i am attempting to do is connect to putty from asp.net c# and then run a command to get the status

i will then use the results to draw a report every 3 seconds and display it on my web page

this is the first time a have attempted this so i am rather ignorant

 private void connect_putty()
    {
        Process sh = new Process();
        sh.StartInfo.FileName = "Putty.exe";
        sh.StartInfo.UseShellExecute = false;
        sh.StartInfo.CreateNoWindow = false;
        sh.StartInfo.Arguments = "";
    }

what i presently have which to be honest is pathetic any help will be appreciated

Thanks in advance

What exactly are you trying to get Putty to do? Connect to a remote host? — Adrian Wragg

Can you clarify if you want to connect to the server via SSH, or you actually want to launch putty and connect to a server? — Dane Balia

It sounds like you want to connect to an SSH server, then execute a command, returning it's result and then graphing it. Ah! Then you need a C# OpenSSH API which will allow you to bypass Putty and speak to the server yourself — Dane Balia

I would suggest using Tamir.SSH. This will allow you to do everything from C#.

Also, I wrote some code once, it may help you.

https://github.com/daneb/Push2Linux/blob/master/Form1.cs

Sample:

 SshShell ssh; // create our shell

 ssh = new SshShell(aHost.host, aHost.username, aHost.password);

 // Command Output
  string commandoutput = string.Empty;

 // Remove Terminal Emulation Characters
  ssh.RemoveTerminalEmulationCharacters = true;

  // Connect to the remote server
  ssh.Connect();

  //Specify the character that denotes the end of response
  commandoutput = ssh.Expect(promptRegex);

PuTTY includes all the terminal emulation (hence the name), so assuming you mean 'connect via ssh', instead of the putty app specifically, then SSH.NET and SharpSSH are 2 good choices.
