3 Ways to Use SSH on Windows to Log Into Linux Server

May 13, 2021

In the business environment, remote networking capabilities are at the forefront of the workflow. Employees require the privilege of accessing the business system at any point in time. It means the network service providers must have an understanding of providing secure remote connectivity for their consumers. That is where the role of the secure shell (SSH). Network MSPs make this protocol instrumental for rendering remote administration functionalities like just logging into a work device from a different location to a more intricate procedure like using this SSH for secure tunnelling to dodge a firewall. Let us now take a look at what SSH is.

What Is SSH Protocol in Networking?
SSH stands for Secure Shell. It is a protocol that uses a secure method to perform network communication safely and securely. It helps in secure remote login in an unsecured network while connecting from one system to another. It has a significant collection of functionalities right from protecting transferred files, command execution, remote access in private network systems to automating various packet transporting processes securely. It acts as a reliable alternative to strong authentication. Also, it helps in preserving the integrity and security with robust encryption mechanisms.

The development of SSH was primarily to address the safety errors that Telnet has. Telnet is a non-protected remote login protocol with an insecure file transfer method. It was SSH-1 that came as a blessing for remote-communication operations with security. Later, SSH-1 got updated with SSH-2. The update strengthened this protocol and became a reliable cryptographic system of remote networking. Let us now understand the three different ways to use SSH on Windows to log in to Linux Server.

3 Methods to Use SSH on Windows
In this article, you will get to know the three different approaches to use SSH on Windows. 

Method 1: Windows 10’s Built-in SSH

It was back in 2015 when the team of Microsoft PowerShell decided to bring OpenSSH into Windows. They successfully ported it in Windows 10 (Fall Creator Update in 2017). It got enabled by default in April 2018's update. Since then, Windows users can use the OpenSSH client without much difficulty. Here are the steps to use OpenSSH in Windows 10.

i. Open the PowerShell window (go to Start and search for "PowerShell") or command prompt window (CMD) and run the 'ssh' command.

Let’s suppose you want to connect to another system having a private IP You will have to write the command ssh e2enetwork@

ii. If you have connected this for the first time, it will prompt you with a host key to accept.

iii. Then enter the required password to log in. After logging in, you can execute your Linux commands for performing administrative tasks.

iv. For logging out of the Linux system, type and execute the exit command. The other way around is to press the shortcut Ctrl + D.

Method 2: Use a Subsystem for Linux within Windows

You can also include a Windows subsystem to use SSH through Windows. Using the Windows Subsystem for Linux (WSL) will enable you to run all the native Linux commands directly on the Windows system. Through this procedure, WSL might use your system's processing power because it will install and execute a Linux distro (without GUI, of course) on your Windows 10 desktop for making you use SSH. Microsoft developed WSL initially for web developers and those who want to work in open-source projects. Later, it became a popular command-line tool that not only supports using SSH but also other command-line tools such as Bash, awk, sed, etc. To use WSL within Windows, follow the steps –

i. Open Microsoft Store.

ii. Type WSL in the search box and hit enter.

iii. Select 'Run Linux on Windows' and install the distro of your choice. You will see different Linux distros like (Ubuntu, OpenSUSE, Kali, Debian, etc.)

iv. Once you install the distro, go to the Control Panel and select Programs -> 'Turn Windows features on or off'. Tick the checkbox associated with 'Windows Subsystem for Linux' for enabling this feature. It might ask for a restart.

v. To launch the Linux distro, go to the Start menu and search the name of your distro. If you are doing this for the first time, it will ask you to create a username and set a password.

vi. Now connect to a Linux PC that runs on an SSH server.

Method 3: Use Putty in Windows

Putty is a popular SSH client that existed before the advent of OpenSSH. Download Putty (https://www.putty.org/), and install it in your Windows system. After that, launch this application. Now, enter the IP address or hostname of the Linux system and press the 'Open' button to connect. Once you accept the host key, it will prompt you to enter your username and password.

We hope this article will help you get a clear understanding of how to use SSH in Windows OS. To perform a secure login into the Linux server from a Windows machine, you must know any of these three methods (shown above) to use SSH from Windows. E2E Cloud has this SSH feature included in the service.

A Complete Guide To Customer Acquisition For Startups

Any business is enlivened by its customers. Therefore, a strategy to constantly bring in new clients is an ongoing requirement. In this regard, having a proper customer acquisition strategy can be of great importance.

So, if you are just starting your business, or planning to expand it, read on to learn more about this concept.

The problem with customer acquisition

As an organization, when working in a diverse and competitive market like India, you need to have a well-defined customer acquisition strategy to attain success. However, this is where most startups struggle. Now, you may have a great product or service, but if you are not in the right place targeting the right demographic, you are not likely to get the results you want.

To resolve this, typically, companies invest, but if that is not channelized properly, it will be futile.

So, the best way out of this dilemma is to have a clear customer acquisition strategy in place.

How can you create the ideal customer acquisition strategy for your business?

  • Define what your goals are

You need to define your goals so that you can meet the revenue expectations you have for the current fiscal year. You need to find a value for the metrics –

  • MRR – Monthly recurring revenue, which tells you all the income that can be generated from all your income channels.
  • CLV – Customer lifetime value tells you how much a customer is willing to spend on your business during your mutual relationship duration.  
  • CAC – Customer acquisition costs, which tells how much your organization needs to spend to acquire customers constantly.
  • Churn rate – It tells you the rate at which customers stop doing business.

All these metrics tell you how well you will be able to grow your business and revenue.

  • Identify your ideal customers

You need to understand who your current customers are and who your target customers are. Once you are aware of your customer base, you can focus your energies in that direction and get the maximum sale of your products or services. You can also understand what your customers require through various analytics and markers and address them to leverage your products/services towards them.

  • Choose your channels for customer acquisition

How will you acquire customers who will eventually tell at what scale and at what rate you need to expand your business? You could market and sell your products on social media channels like Instagram, Facebook and YouTube, or invest in paid marketing like Google Ads. You need to develop a unique strategy for each of these channels. 

  • Communicate with your customers

If you know exactly what your customers have in mind, then you will be able to develop your customer strategy with a clear perspective in mind. You can do it through surveys or customer opinion forms, email contact forms, blog posts and social media posts. After that, you just need to measure the analytics, clearly understand the insights, and improve your strategy accordingly.

Combining these strategies with your long-term business plan will bring results. However, there will be challenges on the way, where you need to adapt as per the requirements to make the most of it. At the same time, introducing new technologies like AI and ML can also solve such issues easily.

Image-based 3D Object Reconstruction State-of-the-Art and trends in the Deep Learning Era

3D reconstruction is one of the most complex issues of deep learning systems. There have been multiple types of research in this field, and almost everything has been tried on it — computer vision, computer graphics and machine learning, but to no avail. However, that has resulted in CNN or convolutional neural networks foraying into this field, which has yielded some success.

The Main Objective of the 3D Object Reconstruction

Developing this deep learning technology aims to infer the shape of 3D objects from 2D images. So, to conduct the experiment, you need the following:

  • Highly calibrated cameras that take a photograph of the image from various angles.
  • Large training datasets can predict the geometry of the object whose 3D image reconstruction needs to be done. These datasets can be collected from a database of images, or they can be collected and sampled from a video.

By using the apparatus and datasets, you will be able to proceed with the 3D reconstruction from 2D datasets.

State-of-the-art Technology Used by the Datasets for the Reconstruction of 3D Objects

The technology used for this purpose needs to stick to the following parameters:

  • Input

Training with the help of one or multiple RGB images, where the segmentation of the 3D ground truth needs to be done. It could be one image, multiple images or even a video stream.

The testing will also be done on the same parameters, which will also help to create a uniform, cluttered background, or both.

  • Output

The volumetric output will be done in both high and low resolution, and the surface output will be generated through parameterisation, template deformation and point cloud. Moreover, the direct and intermediate outputs will be calculated this way.

  • Network architecture used

The architecture used in training is 3D-VAE-GAN, which has an encoder and a decoder, with TL-Net and conditional GAN. At the same time, the testing architecture is 3D-VAE, which has an encoder and a decoder.

  • Training used

The degree of supervision used in 2D vs 3D supervision, weak supervision along with loss functions have to be included in this system. The training procedure is adversarial training with joint 2D and 3D embeddings. Also, the network architecture is extremely important for the speed and processing quality of the output images.

  • Practical applications and use cases

Volumetric representations and surface representations can do the reconstruction. Powerful computer systems need to be used for reconstruction.

Given below are some of the places where 3D Object Reconstruction Deep Learning Systems are used:

  • 3D reconstruction technology can be used in the Police Department for drawing the faces of criminals whose images have been procured from a crime site where their faces are not completely revealed.
  • It can be used for re-modelling ruins at ancient architectural sites. The rubble or the debris stubs of structures can be used to recreate the entire building structure and get an idea of how it looked in the past.
  • They can be used in plastic surgery where the organs, face, limbs or any other portion of the body has been damaged and needs to be rebuilt.
  • It can be used in airport security, where concealed shapes can be used for guessing whether a person is armed or is carrying explosives or not.
  • It can also help in completing DNA sequences.

So, if you are planning to implement this technology, then you can rent the required infrastructure from E2E Networks and avoid investing in it. And if you plan to learn more about such topics, then keep a tab on the blog section of the website

A Comprehensive Guide To Deep Q-Learning For Data Science Enthusiasts

For all data science enthusiasts who would love to dig deep, we have composed a write-up about Q-Learning specifically for you all. Deep Q-Learning and Reinforcement learning (RL) are extremely popular these days. These two data science methodologies use Python libraries like TensorFlow 2 and openAI’s Gym environment.

So, read on to know more.

What is Deep Q-Learning?

Deep Q-Learning utilizes the principles of Q-learning, but instead of using the Q-table, it uses the neural network. The algorithm of deep Q-Learning uses the states as input and the optimal Q-value of every action possible as the output. The agent gathers and stores all the previous experiences in the memory of the trained tuple in the following order:

State> Next state> Action> Reward

The neural network training stability increases using a random batch of previous data by using the experience replay. Experience replay also means the previous experiences stocking, and the target network uses it for training and calculation of the Q-network and the predicted Q-Value. This neural network uses openAI Gym, which is provided by taxi-v3 environments.

Now, any understanding of Deep Q-Learning   is incomplete without talking about Reinforcement Learning.

What is Reinforcement Learning?

Reinforcement is a subsection of ML. This part of ML is related to the action in which an environmental agent participates in a reward-based system and uses Reinforcement Learning to maximize the rewards. Reinforcement Learning is a different technique from unsupervised learning or supervised learning because it does not require a supervised input/output pair. The number of corrections is also less, so it is a highly efficient technique.

Now, the understanding of reinforcement learning is incomplete without knowing about Markov Decision Process (MDP). MDP is involved with each state that has been presented in the results of the environment, derived from the state previously there. The information which composes both states is gathered and transferred to the decision process. The task of the chosen agent is to maximize the awards. The MDP optimizes the actions and helps construct the optimal policy.

For developing the MDP, you need to follow the Q-Learning Algorithm, which is an extremely important part of data science and machine learning.

What is Q-Learning Algorithm?

The process of Q-Learning is important for understanding the data from scratch. It involves defining the parameters, choosing the actions from the current state and also choosing the actions from the previous state and then developing a Q-table for maximizing the results or output rewards.

The 4 steps that are involved in Q-Learning:

  1. Initializing parameters – The RL (reinforcement learning) model learns the set of actions that the agent requires in the state, environment and time.
  2. Identifying current state – The model stores the prior records for optimal action definition for maximizing the results. For acting in the present state, the state needs to be identified and perform an action combination for it.
  3. Choosing the optimal action set and gaining the relevant experience – A Q-table is generated from the data with a set of specific states and actions, and the weight of this data is calculated for updating the Q-Table to the following step.
  4. Updating Q-table rewards and next state determination – After the relevant experience is gained and agents start getting environmental records. The reward amplitude helps to present the subsequent step.  

In case the Q-table size is huge, then the generation of the model is a time-consuming process. This situation requires Deep Q-learning.

Hopefully, this write-up has provided an outline of Deep Q-Learning and its related concepts. If you wish to learn more about such topics, then keep a tab on the blog section of the E2E Networks website.
