# Setup /etc/resolv.conf - you can set

# Brief instructions for this file
##################################################
# DIRECT_SETTINGS_ONLY=(YES/NO)       Default: YES
# Bypass automatic configuration using this file's
# settings, and only execute the commands in
# /etc/network_direct.conf
# VERBOSE=(YES/NO)                    Default: Yes
# Be verbose about settings.
#
# MAX_LOOP=(int)                      Default: 10
# Maximum number of incrementable entries to search<\n>
# for. IE: If you create a DNS7=, and MAX_LOOP=7,
# it will not be reached.
# (DNS0 - DNS7 == 8 entires)
# Setting this value too high will decrease the
# speed of the configuration system.
#
# IPFWDING_KERNEL=(YES/NO)            Default: NO
# Enable IP forwarding in the kernel.
#
# IPFWDING_FW=(YES/NO)                Default: NO
#   (requires ipfwadm)
# Set firewall forwarding policy to 'allow'.
#
# CONFIG_HOSTNAME=(YES/NO)            Default: NO
# Create /etc/hostname file using HOSTNAME entry.
# Any current hostname file will be *OVERWRITTEN*
#
# CONFIG_HOSTSFILE=(YES/NO)      Default: NO
# Create /etc/hosts file using HOSTSx entries.
# Any current hosts file will be **OVERWRITTEN**
#
# CONFIG_DNS=(YES/NO)      Default: NO
# Create /etc/resolv.conf file using DOMAINS and
# DNSx entries.
# Any current resolv.conf file will be **OVERWRITTEN**
