Currently, the recommended approach for installing NI Linux Device Drivers on an offline system is to create a local copy of the online repositories to removable media, such as a USB driver or DVD. Below are some example procedures tested on RHEL 6 and 7 systems. The overall process should be similar with slight variations on other Linux distributions.The RHEL offline installation procedure requires two RHEL systems, similar except that one (host) has an internet connection and one (target) does not. The purpose of the host system is to clone the NI repository to a USB drive or DVD media. Additionally, for the process to work fully offline you must have the official RHEL installation media. This is so that the target system can access RedHat installation packages required by NI software that may not already be present.
At this point, you will need to insert the RHEL installation media to the system, in order to access native dependencies of NI's drivers. Once the installation media is inserted, you can install the desired NI driver through yum, e.g. NI-DAQmx: "yum install ni-daqmx". Note: If any dependency rpm files are missing and RHEL media is unavailable, it is also possible to cache additional rpm files from online RHEL system using the same process for each repository.
