RC.INET1.CONF(5)RC.INET1.CONF(5)NAMErc.inet1.conf - Slackware network configuration file.
DESCRIPTIONrc.inet1.conf It consists basically of a series of variable array defi‐
nitions. Array elements with the same index number will all belong to
the same network interface.
By default, index number `0' is used for the configuration of interface
eth0, index number `1' is used for eth1 and so forth. The default
interface name can be overruled by the use of the variable IFNAME.
This is what a typical section of the file looks like for a card that
is configured to use DHCP, showing all array variables with the index
number [0]:
# Config information for eth0:
IPADDR[0]=""
NETMASK[0]=""
USE_DHCP[0]="yes"
DHCP_HOSTNAME[0]=""
DHCP_TIMEOUT[0]=""
Alternatively, here is an example for a card that uses a static IP
address and has a non-default name ( ath0 instead of eth1 ). The array
index is [1] in this case.
# Config information for ath0 (using static IP address):
IFNAME[1]="ath0"
IPADDR[1]="192.168.3.11"
NETMASK[1]="255.255.255.0"
USE_DHCP[1]=""
DHCP_HOSTNAME[1]=""
GATEWAY="192.168.3.1"
GENERAL PARAMETERS
This is a list of network parameters you can set for any card (wired as
well as wired). The example section is for `eth0' by default, i.e.
the array variables all have the array index [0]:
# Config information for eth0:
IPADDR[0]="" # Set this value to an actual IP address if
you want static IP address assignment
NETMASK[0]="" # With a static IP address, you are required
to also set a netmask (255.255.255.0 is com‐
mon)
USE_DHCP[0]="yes" # If set to "yes", we will run a DHCP client
and have the IP address dynamically assigned
DHCP_HOSTNAME[0]="mybox" # Tell the DHCP server what hostname to regis‐
ter
DHCP_TIMEOUT[0]=15 # The default timeout for the DHCP client to
wait for server response is 30 seconds, but
you might want a shorter wait.
IFNAME[0]="eth0:1" # Set up an IP alias.
HWADDR[0]="00:01:23:45:67:89"
# Overrule the card's hardware MAC address
MTU[0]="" # The default MTU is 1500, but you might need
1360 when you use NAT'ed IPSec traffic.
DHCP_KEEPRESOLV[0]="yes" # If you do not want `/etc/resolv.conf' over‐
written by the DHCP client
DHCP_KEEPNTP[0]="yes" # If you do not want `/etc/ntp.conf' overwrit‐
ten by the DHCP client
DHCP_KEEPGW[0]="yes" # If you do not want the DHCP client to change
your default gateway
DHCP_DEBUG[0]="yes" # Make dhcpcd show verbose diagnostics
DHCP_NOIPV4LL[0]="yes" # Do not assign an `ipv4ll' address when a
DHCP server is not found (ipv4 link-local
addressing in the IP range 169.254.0.0/16 is
also known as `zeroconf' address assignment)
DHCP_IPADDR[0]="" # Request a specific IP address from the DHCP
server
WIRELESS PARAMETERS
For wireless cards, several additional parameter definitions are avail‐
able. All these parameters (or better, variables) start with the pre‐
fix WLAN_ .
WLAN_ESSID[4]=DARKSTAR # Your Wireless Access Point's name
WLAN_MODE[4]=Managed # "Managed" mode for use with Access Points.
"Ad-Hoc" is for peer-to-peer connections.
WLAN_RATE[4]="54M auto" # The transmission rates you want the driver
to try ("auto" means that bandwidth can be
variable)
WLAN_CHANNEL[4]="auto" # The channel to which the Access Point is
tuned ("auto" to let the driver find out the
correct channel)
WLAN_KEY[4]="D5A31F54ACF0487C2D0B1C10D2"
# Definition of a WEP key
WLAN_IWPRIV[4]="set AuthMode=WPAPSK | set EncrypType=TKIP | set
WPAPSK=the_64_character_key"
# Some drivers require a private ioctl to be
set through the iwpriv command. If more than
one is required, you can place them in the
IWPRIV parameter (separated with the pipe (|)
character, see the example).
WLAN_WPA[4]="wpa_supplicant"
# Run wpa_supplicant for WPA support
WLAN_WPADRIVER[4]="ndiswrapper"
# Tell wpa_supplicant to specifically use the
ndiswrapper driver. If you leave this empty
the `wext' driver is used by default; most
modern wireless drivers use 'wext'.
WLAN_WPAWAIT[4]=30 # In case it takes long for the WPA associa‐
tion to finish, you can increase the wait time
before rc.wireless decides that association
failed (defaults to 10 seconds)
FILES
/etc/rc.d/rc.inet1 network configuration script
/etc/rc.d/rc.inet1.conf configuration parameter file (is being read by
rc.inet1 andrc.wireless)
/etc/rc.d/rc.wireless wireless configuration script
/etc/rc.d/rc.wireless.conf
configuration parameter file ( deprecated )
CAVEATS
The network interface definitions are stored in variable arrays. The
bash shell has no facilities to retrieve the largest array index used.
Therefore, the rc.inet1 script makes the assumption that array indexes
stay below the value of 6
If you want to configure more than six network interfaces, you will
have to edit the file /etc/rc.d/rc.inet1 and change the value `6' in
the line MAXNICS=${MAXNICS:-6} to the number of network interfaces you
wish to use.
