C# SSH tunnel to Cisco device through Linux jump

Hi, I am really banging my head on this problem. I would like to make app for automation of many network devices in our network. I decided for Chilkat SSH. We must connect to our network devices through JUMP linux server. Please Help - In my trying I was able to reach cisco device once but I dont know how. Also I would like to have the output of the command.

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;

namespace ConsoleApplication1 {

class Program
{
    static void Main(string[] args)
    {
        //  Important: It is helpful to send the contents of the
        //  ssh.LastErrorText property when requesting support.

        Chilkat.Ssh ssh1 = new Chilkat.Ssh();

        //  Any string automatically begins a fully-functional 30-day trial.
        bool success = ssh1.UnlockComponent("Anything for 30-day trial");
        if (success != true)
        {
            Console.WriteLine(ssh1.LastErrorText);
            return;
        }

        //  Hostname may be an IP address or domain name:
        string hostname = "192.168.29.3";
        int port = 22;

        **/*INITIATE FIRST SSH CONNECTION*/**
        success = ssh1.Connect(hostname, port);
        if (success != true)
        {
            Console.WriteLine(ssh1.LastErrorText);
            return;
        }

        ssh1.IdleTimeoutMs = 15000;

        success = ssh1.AuthenticatePw("root", "neviem");
        if (success != true)
        {
            Console.WriteLine(ssh1.LastErrorText);
            return;
        }

        **/*INITIATE SECOND SSH CONNECTION*/**
        Chilkat.Ssh ssh2 = new Chilkat.Ssh();
        success = ssh2.ConnectThroughSsh(ssh1, "192.168.29.2", 22);
        if (success != true)
        {
            Console.WriteLine(ssh2.LastErrorText);
            return;
        }

        ssh2.IdleTimeoutMs = 15000;

        success = ssh2.AuthenticatePw("root", "cisco");
        if (success != true)
        {
            Console.WriteLine(ssh2.LastErrorText);
            return;
        }

        int channelNum = ssh2.OpenSessionChannel();
        if (channelNum < 0)
        {
            Console.WriteLine(ssh2.LastErrorText);
            return;
        }

        ***/*THIS IS THE SET OF COMMANDS I WANT TO RUN */***
        success = ssh2.ChannelSendString(channelNum, "ena\nshow version\n", "ansi");
        if (success != true)
        {
            Console.WriteLine(ssh2.LastErrorText);
            return;
        }
        var cmdOutput = ssh2.GetReceivedText(channelNum, "ansi");
        Console.WriteLine(cmdOutput);
        Console.ReadKey();

        ssh2.Disconnect();
        ssh1.Disconnect();
    }

} }
