Welcome to the documentation for NMIS_Deps-2.0, a dependency installer designed for RHEL 9. This tool is specifically engineered to operate in air-gapped environments with zero internet connectivity, ensuring seamless installation of RPM packages and Perl modules from source without relying on external repositories or mirrors. It will ensure all dependencies for NMIS and the NMIS Professional Modules are correctly installed.


  • Offline Installation — Installs RPM packages and Perl modules entirely offline, making it ideal for secure or isolated environments.
  • Automatic Installation — Facilitates the easy installation of dependencies from source.
  • Self-Cleaning — Automatically cleans up after the installation process, maintaining a tidy system.
  • Repository-Free — Operates without the need for any online repositories or mirrors.


  • Operating System: RHEL 9
  • The Rhel 9 system must be a Server installation, Server installation with GUI, Workstation installation, or Minimal install w/Rhel 9 Standard system and RPM development packages selected.
  • Privileges: Root access is required to run NMIS_Deps-2.0.
  • The NMIS_Deps self extracting run file in the air-gapped environment.

The Minimal install of RHEL 9 has shown that it can make the Dependancy installer unstable and potentially fail to resolve dependancy chains.

If you intend on using the minimal installation of rhel 9, please ensure that the RHEL 9 Standard system packages and RPM development packages are selected for the best results.
