CMD.exe C# Emulator?

Question

I've been trying very hard to automatically ssh into a Linux server. What's crazy, is that I can create a .bat script, that will do it, but I have to be there physically, to type in the password.

I've tried automating this using System.Diagnostics.Process object in c# to no end. There is no way, I've found, to make this object allow you to see the password prompt. It out puts every line up until that point, and then doesn't output any more lines.

cmd.exe, does really well at allowing you to jump from process to process in a script; It consolidates everything into one screen, and just prompts you for things such as passwords, and then you type them in.

Is there any simple way, in C#, to make cmd.exe think you are a human being typing in it, so I can simulated this programmatically? Otherwise, System.Diagnostics.Process, doesn't seem to offer a way to interacted with a process that outputs a password prompt. You never get to see the prompt that clearly happens when you run the same thing in cmd.exe

Answer 1

You could use

Windows.Forms.SendKeys() to send password as keystrokes

Answer 2

cmd.exe is not the SSH client; it's just a shell for one. Explore the capabilities of the actual client. In PuTTY (very popular!) there's an autologon feature, if you have an SSH key.

Answer 3

Without knowing which commandline tool you are using to ssh to the server, isn't there a commandline parameter to provide a password.

C:\> ssh user@ip -p password

Or have you tried input redirection:

ssh user@ip <
Yourpassword
EOF

In looking into your earlier question, what is the trouble you are having in using the programmer interface?

Are you sure you need a full fledged ssh client, or do you just want to execute a command remotely. If it is the latter you might want to check out plink.
