- Create a new user (in this case “juan”).
useradd -m juan
-mcreates a home folder for the user. This is optional, but we will use this folder for SFTP.
- You can run
adduser juaninstead. In this case, you can skip to step 3.
- Set a password for “juan”.
/etc/ssh/sshd_configand add this at the end:
Match User juan ForceCommand internal-sftp
- With this option, the user won’t be able to connect with SSH, but they may use SFTP (and SCP).
# you can reload instead of restart systemctl restart ssh
By default, SFTP starts at the user’s home directory.
