Introduction

• SFTP is very common way to transfer the file from one server to another.
• Often as a client we recieve SFTP server endpoint to pull the file to our system from other system.
• In this article we will use ruby client to read the remote file which is located on SFTP server.

Note: We are using username and password in this article, but in future article we will use public , private key pair to connect.

SFTP Server

• If you dont have SFTP server then you can setup one on local system or Cloud environment for test purpose.
• I have setup one for my use case on GCP. My Linux environment is based on Ubuntu and I followed this guide to setup SFTP server.

Business Logic

Library

• We will use a popular ruby gem called ‘net-sftp’ to connect to SFTP server.
• get it using gem install
