# This is a test configuration.
# It makes use of a farm built from 4 active servers and 4 backup servers,
# all listenening to different IP addresses on port 80. Health-checks are
# TCP only on port 81 so that iptables rules permit easy selection of which
# servers are enabled or disabled. It checks for the file /alive, and disables
# the server if the response is 404.
#
# Create statistics counters this way :
#
# iptables -N http
# iptables -A OUTPUT -p tcp --syn --dport 80 -j http
# for i in $(seq 1 8); do iptables -A http -d 127.0.0.$i; done
# iptables -A http -d 127.0.0.0/24
#
# Consult the statistics using iptables this way:
#
# iptables --line-numbers -nxvL http
# iptables -Z http
#
# Block individual servers like this :
# iptables -I INPUT -p tcp --dport 81 -d 127.0.0.1 -j DROP
#
# Enable each server like this :
# touch $SRV_ROOT/alive
#
# Disable each server like this :
# rm -f $SRV_ROOT/alive
