## Path:	Network/General
## Description:	Set some general network configuration
## Type:	string("","-","+")
## Default:	"+"
## ServiceRestart: network
#
# DEFAULT_BROADCAST is used when no individual BROADCAST is set. It can get one
# of the following values:
# ""  : don't set a broadcast address
# "-" : use IPADDR with all host bits deleted
# "+" : use IPADDR with all host bits set
DEFAULT_BROADCAST="+"

## Type:	yesno
## Default:	yes
# sometimes we want some script to be executed after an interface has been
# brought up, or before an interface is taken down. 
# default dir is /etc/sysconfig/network/if-up.d for POST_UP and
# /etc/sysconfig/network/if-down.d for PRE_DOWN
# Note: if you use NetworkManager then down scripts will be called after the
# interface is down and not before.
GLOBAL_POST_UP_EXEC="yes"
GLOBAL_PRE_DOWN_EXEC="yes"

## Type:        yesno
## Default:     no
# If ifup should check if an ip address is already in use, set this to yes.
# Make sure that packet sockets (CONFIG_PACKET) are supported in the kernel,
# since this feature uses arping, which depends on that.
# Also be aware that this takes one second per interface; consider that when
# setting up a lot of interfaces. 
CHECK_DUPLICATE_IP="no"

# Switch on/off debug messages for all network configuration stuff. If set to no
# most scripts can enable it locally with "-o debug".
DEBUG="no"

## Type:        yesno
## Default:     yes
# All error and info messages from network and hardware configuration scripts go
# to stderr. Most tools that call sysconfig scripts (udev, rcnetwork, scpm,
# YaST) catch these messages and can log them. So some messages appear twice in

USE_SYSLOG="yes"

## Type:        yesno
## Default:     yes
# There are some services (ppp, ippp, dhcp-client, pcmcia, hotplug) that have to
# change the /etc/resolv.conf dynamically at certain times.  E.g. if ppp/ippp
# establishes a connection and is supplied by the peer with a list of
# nameservers. Or pcmcia needs to set the correct nameserver for the choosen
# configuration scheme. If you don't like these services to change
# /etc/resolv.conf at all, then set this variable to "no".
# If unsure, leave it at the default (which is "yes").

MODIFY_RESOLV_CONF_DYNAMICALLY="yes"

## Type:        yesno
## Default:     no

MODIFY_NAMED_CONF_DYNAMICALLY="no"

## Type:        string

# If you are interested in the connections and nfs mounts that use a

# if CONNECTION_CLOSE_BEFORE_IFDOWN="yes", too.
# WARNING: Be aware that this may terminate applications which use
# these nfs mounts as working directory. Be very carefull if your home
# is mounted via nfs!!!
# WARNING: This may even lead to hanging ifdown processes if there are

CONNECTION_UMOUNT_NFS_BEFORE_IFDOWN="no"

## Type:        string
## Default:     ""
#
# Here you may specify which interfaces have to be up and configured properly
# after 'rcnetwork start'. rcconfig will return 'failed' if any of these
# interfaces is not up. You may use interface names as well but better use
# hardware descriptions of the devices (eth-id-<macaddress> or eth-bus-...  See
# man ifup for 'hardware description'). The network start script will wait for
# these interfaces, but not longer as set in WAIT_FOR_INTERFACES.
# You need not to add dialup or tunnel interfaces here, only physical devices.
# The interface 'lo' is always considered to be mandatory and can be omitted.
#
# If this variable is empty, rcnetwork tries to derive the list of mandatory
# devices automatically from the list of existing configurations. Configurations
# with names bus-pcmcia or bus-usb or with STARTMODE=hotplug are skipped. (try
# '/etc/init.d/rc5.d/S*network start -o debug fake | grep MANDAT')
MANDATORY_DEVICES=""

## Type:	integer

# Set default options for ifplugd. You may also set them in an ifcfg-* file
# individually. Have a look at 'man ifplug' for details. We let ifplugd set the
# interface UP when starting, because there are many interfaces where link beat
# cannot be detected otherwise. If you want the interface to stay down then add
# the option '-a'. If you like ifplugd to beep on cable (un)plug, remove '-b'.

#
# NetworkManager lets the user control interfaces and switches automatically if
# network interfaces lose/gain physical connection. It should be used if you:
# - move between networks frequently
# - want a GUI for network control
# Especially on mobile computers that use mainly one wired and one wireless
# interface NetworkManager will please you.
#
# If you are used to SCPM then you might probably stay with NetControl. But at

# When using NetworkManager you may define a timeout to wait for NetworkManager

NM_ONLINE_TIMEOUT="0"
 
## Type:        yesno
## Default:     yes
#
# When using NetworkManager you may want to trigger special actions when an

# you like. Read more about it in the manpage to NetworkManagerDispatcher.
