NAV is primarily aimed at Linux users, although most *NIXes should do. Successful installations of NAV have taken place on the following Linux distributions:
Installation of NAV on CentOS 5 is documented well in a step-by-step fashion.
Installation of NAV on RHEL4 and CentOS 4 is documented well in a step-by-step fashion.
The universities of Tromsø and Bergen have both been using NAV on FreeBSD, with mixed success. As NAV is developed at NTNU, where Linux servers are prevalent, not much testing has been done on other platforms. This has resulted in several Linux-centric solutions which need to be weeded out.
Work done in the fall of 2004 at the University of Tromsø (UiT) has given results. UiT has continued to run NAV on FreeBSD and will in due time submit installation notes for their NAV 3.8.x install.
