The Igor System Administration Tool

This paper describes the system administration tool we call Igor. Igor is a tool for administrating a large number of UNIX systems in a diverse, networked environment. Igor consists of two parts, an interactive GUI which is controlled by an operator, and a daemon which is run on the UNIX target which actually executes the commands. Igor provides very fast operation, and quick post operation analysis of the results. In normal operations we have run commands on over 600 hosts simultaneously in 60 seconds.
