Sometimes you have to give your users a way to manage files on your server. A typical scenario is a web server where your users manage their websites by themselves.
The classical approach in this scenario was to use FTP to give file management capabilities to your users, but it has many drawbacks:
- You have to provision and maintain a new service on your server;
- FTP is an annoying protocol from a firewall configuration point of view;
- FTP is not encrypted by default, and you have to put some effort to configure an FTP server which is protected from sniffing.
If you are a lazy sysadmin like me you’ll prefer to use a service you already have, which is encrypted by default and do not require a special firewall configuration other than the port 22 you are already using.
ssh to the rescue!
