Tutorial: shellnetbuilder

The shellnetbuilder project is a graphical tool designed to simplify network service management on RHEL-based Linux systems. It allows users to easily configure and control essential services like DHCP, DNS, HTTP, FTP, NFS, and NAT through a user-friendly interface, removing the need for complex command-line operations. Critical configuration scripts are securely encrypted to protect their sensitive logic, with communication between the GUI and backend operations handled via temporary log and status files.
