Connect to Ubuntu VM via SSH in C#

Question

I am trying to connect to an Azure Linux vm via SSH in C# using SSH.NET.

using (var client = new SshClient("my-vm.cloudapp.net", 22, "username", "password​"))
        {
            client.Connect();
            Console.WriteLine("it worked!");
            client.Disconnect();
            Console.ReadLine();
        }

However, I am getting the following exception:

No suitable authentication method found to complete authentication

I am able to to ssh in using these credentials in git bash and Putty, what is the problem?

Answer 1

It means your server reject this method to connect. Usually SSH server only allow public key auth or other two factor auth.

Change your /etc/ssh/sshd_config uncomment #PasswordAuthentication yes

 # Change to no to disable tunnelled clear text passwords
 #PasswordAuthentication yes
