NETCFG-PROFILES(5) ================== NAME ---- netcfg-profiles - netcfg profiles documentation and syntax DESCRIPTION ----------- The *netcfg*(8) profiles are plain text files that defines variables for netcfg behavior. They must be compliant with *bash*(1) shell syntax and usually do not execute any code. They are named '/etc/network.d/$\{profile_name}', where +$\{profile_name\}+ must not contain a newline character and should not start with the `@'-sign. 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 behavior. 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):: Either `static' or `dhcp'. Set to `no' to have netcfg bring the interface up but assign no addresses. 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. +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'. Set to `no' to disable IPv6. +ADDR6+ (required when +IP6+ is `static'):: An array of IPv6 addresses: prefix length may be specified via `1234:bcd::11/64' syntax. +GATEWAY6+ (requires +IP6+ of `static'):: The gateway address for IPv6 routing. +ROUTES6+:: An array of custom routes (of the form _address range_ via _gateway_) +DAD_TIMEOUT+:: Time to wait for Duplicate Address Detection to succeed. Defaults to 3 seconds. DNS configuration ^^^^^^^^^^^^^^^^^ +DNS+:: Array of DNS nameservers. Simply specify the IP's of each of the DNS nameservers. +DNS_OPTIONS+:: Array of ``option'' lines for '/etc/resolv.conf' +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' 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. +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. +PRIORITY+ (optional):: Priority group for the network. The matched network with the highest priority will be selected. Defaults to 0.

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. +MODE+:: Set to `tun' or `tap'. +USER+:: The owning user of the tun/tap interface. +GROUP+:: The owning group of the tun/tap interface. Options for `ppp' connections ----------------------------- +PEER+:: The *pppd*(8) peer to use. +PPP_TIMEOUT+:: *pppd*(8) timeout.
