Using command line(cmd.exe)

I tryed it too but didnt work Vulpes.
Anyway Ill try other solutions. Thanks for your helps.

The problem may be that you're repeating 'ssh' in the parameters as well as the filename.

Try instead:

 string snmp_parametre1 = "[email protected]";

I want to SSH connection to a server and execute commands. It works from command line(cmd.exe). All the outputs are below;
----------
C:\>ssh [email protected]
[email protected]'s password:*****
Last login: Mon May 30 14:23:18 2011 from 172.31.1.195
root@ubuntu:~#
----------

 Then I am using "ssh.exe" for connection. So I used the codes below;

---------
            string snmp_parametre1 = "ssh [email protected]";
            Process islem = new Process();
            islem.StartInfo.FileName = "ssh";
            islem.StartInfo.Arguments = snmp_parametre1;
            islem.StartInfo.RedirectStandardOutput = true;
            islem.StartInfo.UseShellExecute = false;
            islem.Start();
            islem.WaitForExit();

            string output = islem.StandardOutput.ReadToEnd();
            textBox1.Text = output;
----------

But I couldnt send parameter or command. Is it impossible to send a parameter to an .exe file like ssh?

(I could send the parameters to cmd.exe like you say.)

Are you sure that if you execute a bat from a Process object that the output of what the bat file executes is redirected by the Process object? I think not.

Try redirecting output from a command line; in other words, verify your assumption that the output can be redirected. I think it cannot be. I am unable to. Perhaps I am just doing it wrong but I think before you spend more time it is best to ensure that it is not a waste of time.

By definition of what telnet is, it uses formatting commands. It makes sense to me that it is not using standard output. Telnet is a terminal emulator, which is inconsistent with standard output. Telnet's output in a Unix system might use standard output since the command window in Unix systems emulate dumb terminals. Window's command windows do not emulate dumb terminals so I assume that Microsoft is converting the dumb terminal formatting commands to console API functions to do the formatting.

So if telnet won't work, what is the alternative? I think it is possible to use the networking classes to write something that does enough of the equivalent to get what is needed. It is nearly certain that there are already samples that can be used, at least to start with.

As in my earlier example, you need to close the command processor (using the /C switch) immediately after executing the batch file in order to see the output.

So your first line should be:

string snmp_parametre1 = "/C C:\\command.bat";

Guys thanks for your replys. I tryed a lot of possibilities on "cmd.exe" and "telnet.exe" but I couldnt execute simple commands. I make a "command.bat" file and I wrote "dir" command in it, but I can see nothing. I cant see the output.

-------------------
  string snmp_parametre1 = "C:\\command.bat";
  Process islem = new Process();
  islem.StartInfo.FileName = "C:\\Windows\\System32\\cmd.exe";
  islem.StartInfo.Arguments = snmp_parametre1;
  islem.StartInfo.RedirectStandardOutput = true;
  islem.StartInfo.UseShellExecute = false;
  islem.Start();

  string output = islem.StandardOutput.ReadToEnd();
  islem.WaitForExit();
  textBox1.Text = output;
-------------------

To use StandardOutput, you must set ProcessStartInfo.UseShellExecute to false. Also, you should be able to execute telnet without the shell (cmd.exe). Also you should be able to send multiple commands to telnet by redirecting stnadard input.

For some bizarre reason I can't get telnet to execute from within my program, even if I execute it within cmd.exe. I can execute telnet outside my program but if I execute cmd.exe from within my program and then execute telnet it just keeps saying it cannot find it. I can exeute other programs that way but not telnet. It is strange. So the following is a sample Console program that uses the sort program and I hope it shows how to do what you need to do using telnet.

If you want to do multiple things from the command processor, then I'd create a batch file first and then run that:

Thanks for your reply vulpes but I couldnt do that.
For example I want to send 2 commands to "cmd.exe" and I wrote the codes below. But I can see just "Microsoft Windows [Version 6.1.7600]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved."

I cant see the command's output.

--------------
          string snmp_parametre1 = "dir";
  string snmp_parametre2 = "cd windows";
  Process islem = new Process();
  islem.StartInfo.FileName = "C:\\Windows\\System32\\cmd.exe";
  islem.StartInfo.Arguments = snmp_parametre1;
  islem.StartInfo.Arguments = snmp_parametre2;
  islem.StartInfo.RedirectStandardOutput = true;
  islem.StartInfo.UseShellExecute = false;
  islem.Start();
  islem.WaitForExit();

  string output = islem.StandardOutput.ReadToEnd();
  textBox1.Text = output;

You'll have to create a new Process each time you want to send different parameters to telnet.

If you wanted to send more than one parameter in the same session then just separate the parameters with a space.
