Have you tried typing "SSH C#" in a Google search?  There's tons of examples.

Hi,

I tried the below code :

using (SshClient ssh = new SshClient("IP address", port number, "username", "password")) { ssh.Connect(); var result = ssh.RunCommand("df -h"); ssh.Disconnect(); }

I am getting error as Renci.SshNet.Common.SshOperationTimeoutException: Socket read operation has timed out.

You gotta config Linux server.

Code is no problem.

Hi Rico,
 
According to your description and codes, I have created a test demo on my side, it works well.
 
I suggest you could firstly using cmd ping function to check you could access the unix server.
 
If the network is well, I suggest you could check your unix server has enable the remote access.
 
More details about how to enable the ssh remote access, you could refer to below article.
 
https://docs.oracle.com/cd/E18930_01/html/821-2426/gksja.html  
 
Then I suggest you could directly use SSH to connect to the unix server.
 
More details about my test demo, you could refer to below codes:

using Renci.SshNet;
using System;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                using (var client = new SshClient("server ip address", "your user name", "your password"))
                {
                    client.Connect();
                    Console.WriteLine("Connected");

                    string result = client.RunCommand("ifconfig -a").Execute();
                    Console.WriteLine(result);

                    client.Disconnect();
                    Console.WriteLine("Disconnected");
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                Console.WriteLine(ex.StackTrace);
            }

            Console.ReadLine();
        }
    }
}

Result:

Best Regards,
Brando
