# restart-tlb-conference - clean TheLinkBox restart (Paul Aidukas KN2R)
# Used by tlb-admin "Restart TLB" button. See SETUP-INSTRUCTIONS.txt.
#
# WITH-policy pairing: EventScript = .../tlbevent-conference.sh
# (Also kills tlbevent.sh JIC if a leftover no-policy script is running.)
#
# Typical install path:
#   /home/thelinkbox/scripts/restart-tlb-conference
#   chmod 755 /home/thelinkbox/scripts/restart-tlb-conference
#
# Adjust TLB binary / config paths below if your install differs.
