# This file contains the configuration settings for network interfaces.
# If USE_DHCP[interface] is set to "yes", this overrides any other settings.
# If you don't have an interface, leave the settings null ("").

# You can configure network interfaces other than eth0,eth1... by setting
# IFNAME[interface] to the interface's name. If IFNAME[interface] is unset
# or empty, it is assumed you're configuring eth<interface>.

# Several other parameters are available, the end of this file contains a
# comprehensive set of examples.

# =============================================================================

# Config information for eth0:
IPADDR[0]="$RCIPCOPY"
NETMASK[0]="$RCMASKCOPY"
IPALIASES[0]=""
USE_DHCP[0]="$USE_DHCP"
DHCP_HOSTNAME[0]="$DHCP_HOSTNAME"

# Config information for eth1:
IPADDR[1]=""
NETMASK[1]=""
IPALIASES[1]=""
USE_DHCP[1]=""
DHCP_HOSTNAME[1]=""

# Config information for eth2:
IPADDR[2]=""
NETMASK[2]=""
IPALIASES[2]=""
USE_DHCP[2]=""
DHCP_HOSTNAME[2]=""

# Config information for eth3:
IPADDR[3]=""
NETMASK[3]=""
IPALIASES[3]=""
USE_DHCP[3]=""
DHCP_HOSTNAME[3]=""

# Default gateway IP address:
GATEWAY="$GATEWAY"

# Change this to "yes" for debugging output to stdout.  Unfortunately,
# /sbin/hotplug seems to disable stdout so you'll only see debugging output
# when rc.inet1 is called directly.
DEBUG_ETH_UP="no"

# Example of how to configure a bridge:
# Note the added "BRNICS" variable which contains a space-separated list
# of the physical or virtual network interfaces you want to add to the bridge.
#IFNAME[0]="br0"
#BRNICS[0]="eth0"
#IPADDR[0]="192.168.0.1"
#NETMASK[0]="255.255.255.0"
#IPALIASES[0]=""
#USE_DHCP[0]=""
#DHCP_HOSTNAME[0]=""

# Virtual interfaces to create - these are created before any address
# configuration or bridge setup is done, so you may use these interfaces
# as IFNAME or BRNICS values. These can be tun or tap interfaces:
# adjust VIRTIFNAME and VIRTIFTYPE accordingly
#
# Virtual tap interface example
#VIRTIFNAME[0]="tap0"
#VIRTIFTYPE[0]="tap"
#VIRTIFUSER[0]="root"
#VIRTIFGROUP[0]="root"
#
# Virtual tun interface example
#VIRTIFNAME[1]="tun0"
#VIRTIFTYPE[1]="tun"
#VIRTIFUSER[1]="someuser"
#VIRTIFGROUP[1]="somegroup"
