OpenSSH for Windows

-

 OpenSSH is the open-source version of the Secure Shell (SSH) tools used by administrators of Linux and other non-Windows for cross-platform management of remote systems. OpenSSH has been added to Windows (as of autumn 2018), and is included in Windows 10 and Windows Server 2019.

OpenSSH is a connectivity tool for remote login that uses the SSH protocol. It encrypts all traffic between client and server to eliminate eavesdropping, connection hijacking, and other attacks

SSH is based on a client-server architecture where the system the user is working on is the client and the remote system being managed is the server. OpenSSH includes a range of components and tools designed to provide a secure and straightforward approach to remote system administration, including:

  • sshd.exe, which is the SSH server component that must be running on the system being managed remotely
  • ssh.exe, which is the SSH client component that runs on the user's local system
  • ssh-keygen.exe generates, manages and converts authentication keys for SSH
  • ssh-agent.exe stores private keys used for public key authentication
  • ssh-add.exe adds private keys to the list allowed by the server
  • ssh-keyscan.exe aids in collecting the public SSH host keys from a number of hosts
  • sftp.exe is the service that provides the Secure File Transfer Protocol, and runs over SSH
  • scp.exe is a file copy utility that runs on SSH

  Microsoft Office365 EWS servers have been extended to support authorization via the industry-standard OAuth 2.0 protocol. Using OAUTH protocol, user can do authentication by Microsoft Web OAuth instead of inputting user and password directly in application Microsoft / Office 365 OAuth + EWS We can use the OAuth authentication service provided by Azure Active Directory to enable our application to connect with IMAP, POP or SMTP protocols to access Exchange Online in Office 365. To use OAuth with our application we need to register application on Azure Active directory and other steps also we need to do to get the access token back. Below are the steps   To use Microsoft/Office365 OAUTH in your application, you must create an application in  https://portal.azure.com . Sign into the Azure portal using either a work or school account or a personal Microsoft account. If your account gives you access to more than one tenant, select your account in the top ...

IoT technology The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines.  IoT is a network of sensors where data is exchanged, using different connectivity protocols, with systems. This set up can be leveraged to create a new business application or to enhance an existing process. The exchange of the data can be bi-directional between sensors and systems Examples of sensors can be temperature sensors, motion sensors, flow meters, heart meter monitors, biometric devices, smoke detectors, & etc Examples of connectivity can be wifi, radio, GPRS, GSM, LAN, WAN, & etc. Examples of systems can be a remote health monitoring applications, SCADA applications, etc Look at next slide about the complete flow of IoT process Examples A doctor in US would like to monitor the heart rate and ECG of a patient in Hyderabad. This is done with the patient having sensors attached to him that collect the ECG data and the hea...

What is reverse proxy?

  What is a reverse proxy? A reverse proxy is a server that sits in front of web servers and forwards client (e.g. web browser) requests to those web servers. Reverse proxies are typically implemented to help increase  security ,  performance , and reliability . In order to better understand how a reverse proxy works and the benefits it can provide, let’s first define what a proxy server is. What’s a proxy server? A forward proxy, often called a proxy, proxy server, or web proxy, is a server that sits in front of a group of client machines. When those computers make requests to sites and services on the Internet, the proxy server intercepts those requests and then communicates with web servers on behalf of those clients, like a middleman. For example, let’s name 3 computers involved in a typical forward proxy communication: A: This is a user’s home computer B: This is a forward proxy server C: This is a website’s origin server (where the website data is stored) In a stand...
