#Sftp configuration in redhat linux 7 password#
We have a CentOS 7 server already up and running and now we’ll have to configure it in order to accept external connections by using a basic password authentication or by using SSH keys. Before we start let’s make clear one thing, STPF doesn’t mean Secure FTP, it means FTP over SSH and nothing more, we have highlighted that just to avoid any confusion about this term.Īssuming that we have some external / internal applications that needs to get some CSV files exported by another internal / external application or maybe by a SQL server and we need to provide a simple way to facilitate this file exchange process then a simple, easy and fast solution will be to build an SFTP server. We must say that this SFTP solution for sharing and managing files can be also applied even for lower or higher versions as long the principle stays the same in terms of linux user management and also SSH configuration. You can easily manage these files using any (S)FTP clients, directly via your application or maybe via cron jobs, is up to you.

#Sftp configuration in redhat linux 7 how to#
In this tutorial we will learn how to build an SFTP server on CentOS 7 and OpenSSH 7.4 and also providing you two authentication solutions, first one being based on using basic password authentication and the second one by using SSH keys in order to get access to your files. We all agree that an SFTP server can be quite handy or sometimes a must if for example one or more applications within our stack requires file transfer between different processing steps or maybe for backups. Set up an SFTP server on CentOS is our next tutorial where we will guide you as always, step by step, how to build from scratch such a server.
