        Dim connInfo As New Renci.SshNet.PasswordConnectionInfo("111.111.1.1", TextBox1.Text, TextBox2.Text)
        Dim sshClient As New Renci.SshNet.SshClient(connInfo)
        Dim cmd As Renci.SshNet.SshCommand


        Using sshClient
            sshClient.Connect()

            cmd = sshClient.RunCommand("configure terminal")
            cmd = sshClient.RunCommand("users")

            sshClient.Disconnect()
        End Using
    End Sub
