The OpenVMS WHO utility is packaged as a standard VMSINSTALL kit and must be installed to work. Both the VAX and AXP versions of WHO are included in this kit. The WHO VMSINSTALL procedure will automatically install the proper version of WHO (VAX or AXP) for your system. The WHO executable is linked on your system. WHO056 is supported on OpenVMS VAX V6.0 - V6.2 and on OpenVMS Alpha V1.5-1HW - V6.2. In order to use WHO to a remote Node, WHO must be installed on the remote node. Simply install the provided WHO kit on the target node. The system must be rebooted for the WHO network functions to become active. Please be sure and read the release notes. WHO includes a standard OpenVMS help file that explains all of the WHO functions and parameters. WHO uses DECnet as the only supported transport. Therefore DECnet must be active on your system for any of the WHO remote functions. To install WHO: $@sys$update:vmsinstal who056 freewarecd:[who056]
