# This script automates a connectivity test for Perforce Helix Swarm triggers.
# This should be run on the Helix Core (p4d) server machine where Swarm
# triggers are installed.  It tests settings in the swarm-trigger.config
# file including the host and trigger token, as well as testing connectivity
# from the Helix Core to the Helix Swarm server. It exercises things such as
# DNS names, HTTPS certificates (if used), current availability of the Swarm
# server/service, and network firewall rules for port 80 (HTTP) or 443 (HTTPS).
#------------------------------------------------------------------------------
# The core of the test was extracted from a Perforce Support article.
# See the 'Trigger Problems' section of the Knowledge Base article
