# A script that will fetch the IPs of popular add servers.
#
# To use this, just put in your cron jobs, like this:
#
#      0 * * * * /path/to/adblock.sh >/etc/firehol/adblock-ips
#
# and then in your firehol.conf:
#
#     source /etc/firehol/adblock-ips
#
# later in the config file you can use (for example)
#
#     client http accept dst not "${ADSERVERS_IPS}"
#
# or even:
#
#     blacklist full "${ADSERVERS_IPS}"
#
