There are situations when you want to allow a user to access a system solely through FTP, while blocking all other forms of access like SSH or shell logins. This approach is particularly useful in managed hosting environments or shared systems where limiting user capabilities can improve both performance and security. For a deeper understanding of package configurations on Linux systems, check out our article on how to verify if a package is installed in Debian and RHEL-based distros, or explore modern enterprise alternatives like AlmaLinux OS 10.
Restricting shell access while allowing FTP is easy to implement using built-in Linux features. These changes ensure the user cannot initiate an interactive shell session but still has access to FTP services as needed. It’s also a good idea to familiarize yourself with advanced Linux topics such as installing the latest kernel on Ubuntu or understanding symbolic and hard links for better system control.
