[Xymon] Spoofing host names

I have a lab system I am trying to test Xymon with where all of the lab systems have the same host name that is the same as a single production system.

For example, I have 3 lab computers... Lab1, Lab2, Lab3. They all have a hostname of prod101 (this is necessary for other system testing)

How can I test running xymon on these lab systems when they all have the same host name?
