Limit every user to his own home folder only

i have a linux server which users connect to with SSH. my users only upload and download content from their /home folder.

Basicly, I want them to be limited to see and use only their home folder.

I read that it might not be a good idea to do so, since they nead read premissions to run programs and scripts, but again: they are only downloading\uploading content to their home dir.

How can I do it?

Solution 1:

Follow this guide to configure your SSH server to chroot your users.

Essentially, use the ChrootDirectory and ForceCommand rules for sshd_config to limit certain users or groups (Match Group or Match User) to SFTP and a specific directory.

This requires use of the rule Subsystem sftp internal-sftp as well, unless the ChrootDirectory contains all files for a real chroot environment (like a /dev directory with some basic devices)

A different possibility would be to disable shell login. SCP and SFTP might still work for them.
