Open Source Projects
NCSU Realm Linux
NC State University
Project Lead. Realm Linux is a set of modifications applied to the latest version of Red Hat Enterprise Linux to integrate that platform into NC State University’s computer environment. Including Kerberos, hesiod, OpenAFS, LDAP, custom applications, and a completely automated management and installation process for workstations and servers.
- Used in student labs and on research machines throughout campus.
- Powers the main website for NC State University and many other websites.
- Base platform for Web, Cyrus IMAP, LDAP, Samba, Kerberos, MySQL, Webmail, NTP, research clusters, and multiple other services.
- Supports a distributed administration methodology.
- Fosters collaboration with the Open Source community as bugs are reported, patches contributed, and sub-projects are released as open source.
Contributor. Bcfg2 is a configuration management tool written in Python that uses a plugin based architecture.
- Patched the RPM Package Plugin.
- Rewrote the Yum Plugin to make use of the Yum API.
Project Lead. Current is an open source implementation of a server for Red Hat’s up2date program. Long term goals included being a feasible replacement for the Red Hat Network. Versions released were capable of keeping thousands of machines updated. The project was superseded by Red Hat’s release of Spacewalk.
