NAME
====
netcfg-profiles -- netcfg profiles documentation and syntax
DESCRIPTION
===========
The **netcfg**(8) profiles are plain text files that defines variables
for netcfg behaviour. They must be compliant with **bash**(1) shell
syntax and usually do not execute any code.
They are named */etc/network.d/${profile_name}*.
OVERVIEW
========
Profiles must define mandatory variables:
INTERFACE
: The name of the associated network interface.
DESCRIPTION
: A description of the profile.
CONNECTION
: The connection type used by the profile.
Connections define how the network is set up for the profile and also
determine additional configuration variable that control their behaviour.
The available connection types are determined by files in
*/usr/lib/network/connections/*.
Available connections
=====================
ethernet
: Standard network configuration, suitable for wired connections.
wireless
: Wireless connection, with **wpa_supplicant**(1) as configuration
back-end.
bond
: Bonded network interfaces using **ifenslave**.
bridge
: Network bridge setup using **brctl**(8).
tuntap
: TUN/TAP interfaces.
tunnel
: Tunnel interfaces.
vlan
: VLAN setup.
openvpn
: OpenVPN setup.
ppp
: PPP connections setup.
pppoe
: PPPoE connections setup.
The configuration variable for these connection types is described in the
following sections.
Ethernet options reference
==========================
## Description
This connection method uses the iproute suite of tools and dhcpcd to gain an IP address.
IP (required for IPv4)
: Can be either 'static' or 'dhcp'. Static requires at least one of ADDR or IPCFG.
## IPv4 options
ADDR (requires IP of 'static')
: A single IP address to configure a static IP. For example:
GATEWAY (requires IP of 'static')
: Set specified gateway
NETMASK (requires IP of 'static')
: Set specified netmask. Defaults to 24
ROUTES
: An array of custom routes (of the form *address range* via *gateway*)
## IPv6 options
IP6 (required for IPv6)
: Either 'dhcp', 'dhcp-noaddr', 'stateless', 'static'. Leave unset to disable IPv6.
ADDR6 (required for IP6=static)
: An array of IPv6 addresses: prefix length may be specified via '1234:bcd::11/64' syntax.
GATEWAY6 (for IP6=static)
: The gateway address for IPv6 routing.
ROUTES6
: An array of custom routes (of the form *address range* via *gateway*)
### DNS configuration
DNS
: Array of DNS nameservers. Simply specify the IP's of each of the DNS nameservers.
SEARCH
: "search" line for /etc/resolv.conf
DOMAIN
: "domain" line for /etc/resolv.conf
HOSTNAME
: Set the system hostname. Ensure any hostname is correctly referenced in /etc/hosts.
DNS1, DNS2 (deprecated)
: First and second DNS servers for /etc/resolv.conf
### DHCP configuration
DHCP_OPTIONS (ipv4)
: String. Any extra arguments to pass to the dhcp client, presently dhcpcd.
DHCP_TIMEOUT
: Integer. Maximum time to try for a DHCP IP. Default is 10 seconds.
DHCLIENT
: yes/no. Use dhclient instead of dhcpcd. Defaults to no
DHCLIENT_OPTIONS (ipv4)
: String. Extra options to pass to dhclient for IPv4.
DHCLIENT6_OPTIONS (ipv6)
: String. Extra options to pass to dhclient for IPv6.
### 802.11x Authentication
AUTH8021X
: Use 802.11x authentication. Enable with 'yes'.
WPA_CONF (required for an AUTH8021X of 'yes' only)
: Path to wpa_supplicant configuration. Defaults to '/etc/wpa_supplicant.conf'
WPA_OPTS (optional for an AUTH8021X of 'yes')
: Extra arguments for wpa_supplicant not specified otherwise. Any
option here must specify wpa_supplicant driver. Defaults to '-Dwired'.
### Miscellaneous options
IPCFG
: Array of arguments to pass to 'ip'. The power of this options is that
it allows both simple and complicated routing configurations, within the
framework of netcfg.
IFOPTS (deprecated, requires IP of 'static')
: Arguments to pass to 'ifconfig'. This allows you to use the syntax
for the older 'ifconfig' tool. Retained for compatability.
SKIPNOCARRIER
: yes/no. Don't abort interface setup if no carrier is found.
## Examples
### Using ADDR and GATEWAY to set static IP and gateway
IP="static"
ADDR="192.168.1.23"
GATEWAY="192.168.1.1"
### Using IPCFG to set a static IP and gateway with custom DNS
IP="static"
IPCFG=("addr add dev eth0 192.168.1.23/24 brd +" "route add default via 192.168.1.1")
DNS=("208.67.222.222" "208.67.220.220")
Wireless options reference
==========================
## Description
This connection method uses wpa_supplicant to configure a wireless
network connection. This connection uses the 'ethernet' connection after
successful association and thus supports all of its options.
## Options
SECURITY (required for security of 'wep', 'wpa', 'wpa-configsection' or 'wpa-config')
: One of 'wpa', 'wep', 'none', 'wpa-configsection' or 'wpa-config'. Defaults to 'none'.
KEY (required for SECURITY of 'wpa' or 'wep' only)
: Wireless encryption key.
ESSID (this or AP is required)
: Name of network to connect to, or hexadecimal digits (see
'ESSID_TYPE')
ESSID_TYPE (optional, defaults to 'ascii')
: Set to 'ascii' or 'hex', if set to 'hex', ESSID will be interpreted
as an hexadecimal SSID and written unquoted to the wpa_supplicant
configuration file.
AP (this or ESSID is required)
: AP (BSSID) of the network to connect to.
HIDDEN (optional)
: Define this to connect to hidden ESSIDs.
ADHOC (optional)
: Define this to use ad-hoc mode for wireless.
TIMEOUT (optional)
: Time to wait for association. Defaults to 15 seconds.
SCAN (optional)
: yes/no Scan for a wireless network rather than blindly attempting to
connect. Hidden SSID networks do not appear in a scan.
IWCONFIG (optional, deprecated)
: Run iwconfig with these options before attempting to configure the connection.
### WPA options
WPA_CONF (for SECURITY of 'wpa-config' only)
: Path to wpa_supplicant configuration. Defaults to '/etc/wpa_supplicant.conf'
WPA_OPTS
: Extra arguments for wpa_supplicant not specified otherwise.
WPA_GROUP
: Group that has authority to configure wpa_supplicant via it's control
interface. Used in any configuration that is generated by netcfg.
WPA_COUNTRY (optional, nl80211 based drivers)
: The country where the device will be used. This allows wpa_supplicant
to enforce any local regulatory limitations and will allow all
appropriate channels/frequencies for your device.
WPA_DRIVER (optional)
: A comma-separated list of wpa_supplicant driver interfaces to try. Defaults to 'nl80211,wext'.
### rfkill (Radio Kill Switch) options
RFKILL
: hard/soft A switch with physical on/off state that cannot be
controlled via software is considered a 'hard' switch. Any switch that
can be controlled via software is considered 'soft'.
RFKILL_NAME
: Some switches sysfs entries are not linked with the interface. To
match them up, configure the name from /sys/class/rfkill/rfkillX/name
here so that netcfg can identify which to control.
Options for 'bridge' connections
================================
The options of 'ethernet' connections apply to set up standard IP connectivity.
BRIDGE_INTERFACES
: List of network interfaces taking part in the bridge.
FWD_DELAY
: Forward delay of the bridge, see **brctl**(8)
MAX_AGE
: maxage parameter, see **brctl**(8)
Options for 'tuntap' connections
================================
The options of 'ethernet' connections apply to set up standard IP connectivity.
