# QUICK-START
#
# The quickest start is if you want to use DHCP.
# In that case, everything should work out of the box, no configuration
# necessary, though the startup script will warn you that you haven't
# specified anything.

# WARNING :- some examples have a mixture of IPv4 (ie 192.168.0.1) and IPv6
# (ie 4321:0:1:2:3:4:567:89ab) internet addresses. They only work if you have
# the relevant kernel option enabled. So if you don't have an IPv6 enabled
# kernel then remove the IPv6 address from your config.

# If you want to use a static address or use DHCP explicitly, jump
# down to the section labeled INTERFACE HANDLERS.
#
# If you want to do anything more fancy, you should take the time to
# read through the rest of this file.

##############################################################################
# MODULES
#
# We now support modular networking scripts which means we can easily
# add support for new interface types and modules while keeping
# compatibility with existing ones.
#
# Modules load by default if the package they need is installed.  If
# you specify a module here that doesn't have its package installed
# then you get an error stating which package you need to install.
# Ideally, you only use the modules setting when you have two or more
# packages installed that supply the same service.
#
# In other words, you probably should DO NOTHING HERE...

##############################################################################
# INTERFACE HANDLERS

# For a static configuration, use something like this
#config_eth0="192.168.0.2/24"

# If you need more than one address, you can use something like this
# NOTE: ifconfig creates an aliased device for each extra IPv4 address
#       (eth0:1, eth0:2, etc)
#       iproute2 does not do this as there is no need to
#config_eth0="192.168.0.2/24 192.168.0.3/24 192.168.0.4/24"

# You can also use IPv6 addresses
# (you should always specify a prefix length with IPv6 here)
#config_eth0="192.168.0.2/24 4321:0:1:2:3:4:567:89ab/64 4321:0:1:2:3:4:567:89ac/64"

# If you wish to keep existing addresses + routing and the interface is up,
# you can specify a noop (no operation). If the interface is down or there
# are no addresses assigned, then we move onto the next step (default dhcp)
# This is useful when configuring your interface with a kernel command line
# or similar
#config_eth0="noop 192.168.0.2/24"

# If you don't want ANY address (only useful when calling for advanced stuff)
#config_eth0="null"

# Here's how to do routing if you need it
# We add an IPv4 default route, IPv4 subnet route and an IPv6 unicast route
#routes_eth0="default via 192.168.0.1
#10.0.0.0/8 via 192.168.0.1
#::/0"

# If a specified module fails (like dhcp - see below), you can specify a
# fallback like so
#fallback_eth0="192.168.0.2 netmask 255.255.255.0"
#fallback_routes_eth0="default via 192.168.0.1"

# NOTE: fallback entry must match the entry location in config_eth0
# As such you can only have one fallback route.
# Also, if you do not set a fallback_routes entry for an interface, the
# routes entry will be used if that is set.

# Some users may need to alter the MTU - here's how
#mtu_eth0="1500"

# Most drivers that report carrier status function correctly, but some do not
# One of these faulty drivers is for the Intel e1000 network card, but only
# at boot time. To get around this you may alter the carrier_timeout value for
# the interface. 0 is disable and any other number of seconds is how
# long we wait for carrier. The current default is disabled.
#carrier_timeout_eth0=0

# You may wish to disable the interface being brought down when stopping.
# This is only of use for WakeOnLan.
#ifdown_eth0="NO"

# OPTIONAL MODULES

#-----------------------------------------------------------------------------
# WIRELESS (802.11 support)
# Wireless can be provided by BSDs ifconfig (iwconfig) or wpa_supplicant
# wpa_supplicant is preferred, use the modules directive to prefer iwconfig.
#modules="iwconfig"

# ifconfig (iwconig) support is a one shot script - wpa_supplicant is daemon
# that scans, associates and re-configures if association is lost.
# We call it iwconfig to separate the wireless setup from ifconfig.
####################################
# HINTS
#
# Most users will just need to set the following options
# key_SSID1="s:yourkeyhere enc open" # s: means a text key
# key_SSID2="aaaa-bbbb-cccc-dd"      # no s: means a hex key
# preferred_aps="SSID1 SSID2"
#
# Clear? Good. Now configure your wireless network below

####################################
# SETTINGS
# Hard code an SSID to an interface - leave this unset if you wish the driver
# to scan for available Access Points
# I would only set this as a last resort really - use the preferred_aps
# setting at the bottom of this file
#essid_eth0='foo'

# Some drivers/hardware don't scan all that well. We have no control over this
# but we can say how many scans we want to do to try and get a better sweep of
# the area. The default is 1.
#scans_eth0="1"

#Channel can be set (1-14), but defaults to 3 if not set.
#
# The below is taken verbatim from the BSD wavelan documentation found at
# http://www.netbsd.org/Documentation/network/wavelan.html
# There are 14 channels possible; We are told that channels 1-11 are legal for
# North America, channels 1-13 for most of Europe, channels 10-13 for France,
# and only channel 14 for Japan. If in doubt, please refer to the documentation
# that came with your card or access point. Make sure that the channel you
# select is the same channel your access point (or the other card in an ad-hoc
# network) is on. The default for cards sold in North America and most of Europe
# is 3; the default for cards sold in France is 11, and the default for cards
# sold in Japan is 14.
#channel_eth0="3"

# Setup any other config commands. This is basically the ifconfig argument
# without the ifconfig $iface.
#ifconfig_eth0=""
# You can do the same per SSID too.
#ifconfig_SSID=""

# Seconds to wait until associated. The default is to wait 10 seconds.
# 0 means wait indefinitely. WARNING: this can cause an infinite delay when
# booting.
#associate_timeout_eth0="5"

# Define a WEP key per SSID or MAC address (of the AP, not your card)
# The encryption type (open or restricted) must match the
# encryption type on the Access Point.
# To set a hex key, prefix with 0x
#key_SSID="0x12341234123412341234123456"
# or you can use strings. Passphrase IS NOT supported
#key_SSID="foobar"

# per SSID - which is very handy if you use different networks a lot
#config_SSID="dhcp"

#dns_domain_SSID="some.domain"
#dns_search_SSID="search.this.domain search.that.domain"
# Please check the man page for resolv.conf for more information
# as domain and search (searchdomains) are mutually exclusive and
# searchdomains takes precedence

# You can also set any of the /etc/conf.d/net variables per MAC address
# incase you use Access Points with the same SSID but need different

# method with other variables
#config_001122334455="dhcp"
#dns_servers_001122334455="192.168.0.1 192.168.0.2"

# This is used when the Access Point is not broadcasting its SSID
# WARNING: This will override the SSID being broadcast due to some

# not to!
# Change 001122334455 to the MAC address and SSID to the SSID
# it should map to
#mac_essid_001122334455="SSID"

# If this isn't defined then it connects to the first one found
#preferred_aps="SSID1 SSID2"

# You can also define a preferred_aps list per interface
#preferred_aps_eth0="SSID3 SSID4"

# You can also say whether we only connect to preferred APs or not
# Values are "any", "preferredonly", "forcepreferred", "forcepreferredonly"
# and "forceany"
# "any" means it will connect to visible APs in the preferred list and then
# any other available AP
# "preferredonly" means it will only connect to visible APs in the preferred
# list
# "forcepreferred" means it will forcibly connect to APs in order if it does
# not find them in a scan
# "forcepreferredonly" means it forcibly connects to the APs in order and
# does not bother to scan
# "forceany" does the same as forcepreferred + connects to any other
# available AP
# Default is "any"
#associate_order="any"
#associate_order_eth0="any"

# You can define blacklisted Access Points in the same way
#blacklist_aps="SSID1 SSID2"
#blacklist_aps_eth0="SSID3 SSID4"

# If you have more than one wireless card, you can say if you want
# to allow each card to associate with the same Access Point or not
# Values are "yes" and "no"
# Default is "yes"
#unique_ap="yes"
#unique_ap_eth0="yes"

# IMPORTANT: preferred_only, blacklisted_aps and unique_ap only work when
# essid_eth0 is not set and your card is capable of scanning

# NOTE: preferred_aps  list ignores blacklisted_aps - so if you have
# the same SSID in both, well, you're a bit silly :p

# WIRELESS SSID IN VARIABLES
##############################################################################
# Remember to change SSID to your SSID.
# Say that your SSID is My NET - the line
#      #key_SSID="s:passkey"
# becomes
#      #key_My_NET="s:passkey"
# Notice that the space has changed to an underscore - do the same with all
# characters not in a-z A-Z (English alphabet) 0-9. This only applies to
# variables and not values.
#
# Any SSID's in values like essid_eth0="My NET" may need to be escaped
# This means placing the character \ before the character
# \" need to be escaped for example
# So if your SSID is
#      My "\ NET
# it becomes
#      My \"\\ NET
# for example
#      #essid_eth0="My\"\\NET"
#
# So using the above we can use
#      #dns_domain_My____NET="My\"\\NET"
# which is an invalid dns domain, but shows the how to use the variable
# structure
#########################################################

#-----------------------------------------------------------------------------
# DHCP
# DHCP can be provided by dhclient.
#
# dhcpcd:   emerge net-misc/dhcpcd
# dhclient: emerge net-misc/dhcp

# Regardless of which DHCP client you prefer, you configure them the
# same way using one of following depending on which interface modules
# you're using.
#config_eth0="dhcp"

# For passing custom options to dhcpcd use something like the following.  This
# example reduces the timeout for retrieving an address from 60 seconds (the
# default) to 10 seconds.
#dhcpcd_eth0="-t 10"

# GENERIC DHCP OPTIONS
# Set generic DHCP options like so
#dhcp_eth0="release nodns nontp nonis nogateway nosendhost"

# This tells the dhcp client to release its lease when it stops, not to
# overwrite dns, ntp and nis settings, not to set a default route and not to
# send the current hostname to the dhcp server and when it starts.
# You can use any combination of the above options - the default is not to
# use any of them.


#-----------------------------------------------------------------------------
# System
# For configuring system specifics such as domain, dns, ntp and nis servers
# It's rare that you would need todo this, but you can anyway.
# This is most benefit to wireless users who don't use DHCP so they can change
# their configs based on SSID.

# If you omit the _eth0 suffix, then it applies to all interfaces unless
# overridden by the interface suffix.
#dns_domain_eth0="your.domain"
#dns_servers_eth0="192.168.0.2 192.168.0.3"

#dns_options_eth0="timeout:1 rotate"
#dns_sortlist_eth0="130.155.160.0/255.255.240.0 130.155.0.0"
# See the man page for resolv.conf for details about the options and sortlist
# directives

#ntp_servers_eth0="192.168.0.2 192.168.0.3"

#nis_domain_eth0="domain"
#nis_servers_eth0="192.168.0.2 192.168.0.3"

# NOTE: Setting any of these will stamp on the files in question. So if you
# don't specify dns_servers but you do specify dns_domain then no nameservers
# will be listed in /etc/resolv.conf even if there were any there to start
# with.
# If this is an issue for you then maybe you should look into a resolv.conf
# manager like resolvconf-gentoo to manage this file for you. All packages
# that baselayout supports use resolvconf-gentoo if installed.

# ADVANCED CONFIGURATION
#
# Four functions can be defined which will be called surrounding the
# start/stop operations.  The functions are called with the interface
# name first so that one function can control multiple adapters. An extra two
# functions can be defined when an interface fails to start or stop.
#
# The return values for the preup and predown functions should be 0
# (success) to indicate that configuration or deconfiguration of the
# interface can continue.  If preup returns a non-zero value, then
# interface configuration will be aborted.  If predown returns a
# non-zero value, then the interface will not be allowed to continue
# deconfiguration.
#
# The return values for the postup, postdown, failup and faildown functions are
# ignored since there's nothing to do if they indicate failure.
#
# ${IFACE} is set to the interface being brought up/down
# ${IFVAR} is ${IFACE} converted to variable name bash allows
#
# For historical and compatibility reasons, preup is actually normally called
# in the following sequence: up ; preup ; up.
# The first up causes the kernel to initialize the device, so
# that it is available for use in the preup function.  However, for some
# hardware, e.g. CAN devices, some configuration is needed before trying to up
# the interface will actually work. For such hardware, the
# up_before_preup variables will allow skipping the first up call if set
# to yes.
#up_before_preup_IFVAR="NO"
#up_before_preup="NO"

#preup() {
#	# Remember to return 0 on success
#	return 0
#}

#	# The default in the script is to test for NFS root and disallow
#	# downing interfaces in that case.  Note that if you specify a
#	# predown() function you will override that logic.  Here it is, in
#	# case you still want it...
