#OPENSSH SFTP HOW TO#

(Example: ssh or ssh once the server is accessed, you should be able to access root with sudo -s and entering the administrative user's password.

use ssh to log in as one of the administrative users to the server.

Now test access to the server via ssh for your two administrative users. Passwd: all authentication tokens updated successfully. Taking all of these steps will allow you to offer secure SFTP access for your customers while also minimizing the possibility that port 22 (the one reserved for SSH access) will be compromised by a bad actor.

The fourth, and last section of this document deals with turning off remote root logins.

The third part deals with setting up public/private key SSH access for your system administrators and turning off remote password-based authentication.

The second deals with the setup of the change root jail, and if you decide that you want to stop there, that's totally up to you.

The first deals with the general information that we will use for the entire document.

For this reason, this document is divided into four parts:

The author also feels that it is necessary when making the change root jail document for SFTP to also discuss the other things that you should do as a system administrator to minimize the target that you offer to the world via SSH. If that isn't your use case, you can easily adapt these concepts to use in different situations. There are many documents out there that deal with creating an SFTP change root jail, but most do not take into account a use case where the user that is set up would be accessing a web directory on a server with multiple websites.

#OPENSSH SFTP HOW TO#

This document will describe how to implement a change root jail 1 for SFTP while keeping SSH access limited. But most system administrators do not want to open up SSH to everyone in order to implement SFTP for everyone. It may seem strange to have a document dedicated to the 'secure' use of SFTP (a part of openssh-server package) when the SSH protocol is itself secure.
