Introduction

What we want is to allow John to connect through sftp only (no bash, no terminal) and to be limited to a set of folders.

In this example, we'll consider an existing user john, whose home directory is /home/john. You'll have to adapt the different commands to your specific case.

User preparation

We need our user to customized a bit. First of all the, its home directory must be owned by root: chown -c root:root /home/john
