Realm Linux is an Open Source project to create and maintain a managed Linux computing platform for NC State University. Designed for highly available servers, computational and research workstations, office use, and computer labs, Realm Linux is a versatile framework that aims to unify NCSU’s computing environment. Realm Linux is used widely throughout the university for production workloads including high traffic web server pools, hundreds of lab machines, database applications, file serving, research computing, LDAP pools, printing, and secure authentication services.


Realm Linux boasts an array of features to automate and simplify system administration tasks for large numbers of machines.

  • Used widely throughout NC State University and by many system administrators. Institutional knowledge enables system administrators to help and advise each other on various solutions.
  • Centralized and secure management of root passwords where changes propagate within 4 hours. Or completely localized root passwords.
  • Built using the latest versions of Red Hat Enterprise Linux.
  • Supported by the NCSU Help Desk and via a Red Hat support contract.
  • Advanced configuration management tools allow system administrators to control every aspect of their machines even from remote locations.
  • Works outside of NC State University’s networks.
  • Automated propagation of security errata and system updates. Never be faced with annoying messages reminding you to update your systems.
  • NCSU accounts authenticated by Unity username and password. Localized accounts can be created at the discretion of the system administrator.
  • Centralized management of system administrators permitted to obtain root access or localized management.
  • Realm Linux “departments” divide machines into separate domains of control for each IT group on campus.
  • Centralized or localized file and print services.
  • Development process open to all that wish to contribute.
