Is it possible to use OS tools instead of ICMP services for the Host agents and/or Foglgiht Agent Manager (FglAM)?
Currently a user with root permissions is needed to get this working or grant permissions to execution the udp2icmp without password - see the documentation:
"If the user account launching the Agent Manager application is not the root user, they must be granted permissions to execute the <fglam_home>/client/<build id>/bin/udp2icmp application without providing a password."
When using OS tools this step might not be needed.
