Site configuration ================== The ``site`` consists of the files ``site.conf`` and ``site.mk``. In the first community based values are defined, which both are processed during the build process and runtime. The last is directly included in the make process of Gluon. Configuration ------------- The ``site.conf`` is a lua dictionary with the following defined keys. hostname_prefix A string which shall prefix the default hostname of a device. site_name The name of your community. site_code The code of your community. It is good practice to use the TLD of your community here. prefix4 The IPv4 Subnet of your community mesh network in CIDR notation, e.g. :: prefix4 = '10.111.111.0/18' prefix6 The IPv6 subnet of your community mesh network, e.g. :: prefix6 = 'fdca::ffee:babe:1::/64' timezone The timezone of your community live in, e.g. :: -- Europe/Berlin timezone = 'CET-1CEST,M3.5.0,M10.5.0/3' ntp_server List of NTP servers available in your community or used by your community, e.g.: :: ntp_servers = {'1.ntp.services.ffeh','2.ntp.services.ffeh'} This NTP servers must be reachable via IPv6 from the nodes. If you don't want to set an IPv6 address explicitly, but use a hostname (which is recommended), see also the :ref:`FAQ `. opkg \: optional ``opkg`` package manager configuration. There are two optional fields in the ``opkg`` section: - ``openwrt`` overrides the default OpenWrt repository URL - ``extra`` specifies a table of additional repositories (with arbitrary keys) :: opkg = { openwrt = 'http://opkg.services.ffeh/openwrt/%n/%v/%S/packages', extra = { modules = 'http://opkg.services.ffeh/modules/gluon-%GS-%GR/%S', }, } There are various patterns which can be used in the URLs: - ``%n`` is replaced by the OpenWrt version codename (e.g. "chaos_calmer") - ``%v`` is replaced by the OpenWrt version number (e.g. "15.05") - ``%S`` is replaced by the target architecture (e.g. "ar71xx/generic") - ``%GS`` is replaced by the Gluon site code (as specified in ``site.conf``) - ``%GV`` is replaced by the Gluon version - ``%GR`` is replaced by the Gluon release (as specified in ``site.mk``) regdom \: optional The wireless regulatory domain responsible for your area, e.g.: :: regdom = 'DE' Setting ``regdom`` in mandatory if ``wifi24`` or ``wifi5`` is defined. wifi24 \: optional WLAN configuration for 2.4 GHz devices. ``channel`` must be set to a valid wireless channel for your radio. There are currently three interface types available. You many choose to configure any subset of them: - ``ap`` creates a master interface where clients may connect - ``mesh`` creates an 802.11s mesh interface with forwarding disabled - ``ibss`` creates an ad-hoc interface Each interface may be disabled by setting ``disabled`` to ``true``. This will only affect new installations. Upgrades will not changed the disabled state. ``ap`` requires a single parameter, a string, named ``ssid`` which sets the interface's ESSID. ``mesh`` requires a single parameter, a string, named ``id`` which sets the mesh id. ``ibss`` requires two parametersr: ``ssid`` (a string) and ``bssid`` (a MAC). An optional parameter ``vlan`` (integer) is supported. Both ``mesh`` and ``ibss`` accept an optional ``mcast_rate`` (kbit/s) parameter for setting the default multicast datarate. :: wifi24 = { channel = 11, ap = { ssid = 'entenhausen.freifunk.net', }, mesh = { id = 'entenhausen-mesh', mcast_rate = 12000, }, ibss = { ssid = 'ff:ff:ff:ee:ba:be', bssid = 'ff:ff:ff:ee:ba:be', mcast_rate = 12000, }, }, wifi5 \: optional Same as `wifi24` but for the 5Ghz radio. next_node \: package Configuration of the local node feature of Gluon :: next_node = { ip4 = '10.23.42.1', ip6 = 'fdca:ffee:babe:1::1', mac = 'ca:ff:ee:ba:be:00' } mesh \: optional Options specific to routing protocols. At the moment, only the ``batman_adv`` routing protocol has such options: The optional value ``gw_sel_class`` sets the gateway selection class. The default class 20 is based on the link quality (TQ) only, class 1 is calculated from both the TQ and the announced bandwidth. :: mesh = { batman_adv = { gw_sel_class = 1, }, } fastd_mesh_vpn Remote server setup for the fastd-based mesh VPN. The `enabled` option can be set to true to enable the VPN by default. If `configurable` is set to `false` or unset, the method list will be replaced on updates with the list from the site configuration. Setting `configurable` to `true` will allow the user to add the method ``null`` to the beginning of the method list or remove ``null`` from it, and make this change survive updates. Setting `configurable` is necessary for the package `gluon-luci-mesh-vpn-fastd`, which adds a UI for this configuration. In any case, the ``null`` method should always be the first method in the list if it is supported at all. You should only set `configurable` to `true` if the configured peers support both the ``null`` method and methods with encryption. :: fastd_mesh_vpn = { methods = {'salsa2012+umac'}, -- enabled = true, -- configurable = true, mtu = 1280, groups = { backbone = { -- Limit number of connected peers from this group limit = 1, peers = { peer1 = { key = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX', -- Having multiple domains prevents SPOF in freifunk.net remotes = { 'ipv4 "vpn1.entenhausen.freifunk.net" port 10000', 'ipv4 "vpn1.entenhausener-freifunk.de" port 10000', }, }, peer2 = { key = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX', -- You can also omit the ipv4 to allow both connection via ipv4 and ipv6 remotes = {'"vpn2.entenhausen.freifunk.net" port 10000'}, }, }, -- Optional: nested peer groups -- groups = { -- lowend_backbone = { -- limit = 1, -- peers = ... -- }, -- }, }, -- Optional: additional peer groups, possibly with other limits -- peertopeer = { -- limit = 10, -- peers = { ... }, -- }, }, bandwidth_limit = { -- The bandwidth limit can be enabled by default here. enabled = false, -- Default upload limit (kbit/s). egress = 200, -- Default download limit (kbit/s). ingress = 3000, }, } mesh_on_wan \: optional Enables the mesh on the WAN port (``true`` or ``false``). mesh_on_lan \: optional Enables the mesh on the LAN port (``true`` or ``false``). poe_passthrough \: optional Enable PoE passthrough by default on hardware with such a feature. autoupdater \: package Configuration for the autoupdater feature of Gluon. The mirrors are checked in random order until the manifest could be downloaded successfully or all mirrors have been tried. :: autoupdater = { branch = 'stable', branches = { stable = { name = 'stable', mirrors = { 'http://[fdca:ffee:babe:1::fec1]/firmware/stable/sysupgrade/', 'http://autoupdate.entenhausen.freifunk.net/firmware/stable/sysupgrade/', }, -- Number of good signatures required good_signatures = 2, pubkeys = { 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX', -- someguy 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX', -- someother } } } } All configured mirrors must be reachable from the nodes via IPv6. If you don't want to set an IPv6 address explicitly, but use a hostname (which is recommended), see also the :ref:`FAQ `. roles \: optional Optional role definitions. Nodes will announce their role inside the mesh. This will allow in the backend to distinguish between normal, backbone and service nodes or even gateways (if they advertise that role). It is up to the community which roles to define. See the section below as an example. ``default`` takes the default role which is set initially. This value should be part of ``list``. If you want node owners to change the role via config mode add the package ``gluon-luci-node-role`` to ``site.mk``. The strings to display in the LuCI interface can be configured per language in the ``i18n/en.po``, ``i18n/de.po``, etc. files of the site repository using message IDs like ``gluon-luci-node-role:role:node`` and ``gluon-luci-node-role:role:backbone``. :: roles = { default = 'node', list = { 'node', 'test', 'backbone', 'service', }, }, setup_mode \: package Allows skipping setup mode (config mode) at first boot when attribute ``skip`` is set to ``true``. This is optional and may be left out. :: setup_mode = { skip = true, }, legacy \: package Configuration for the legacy upgrade path. This is only required in communities upgrading from Lübeck's LFF-0.3.x. :: legacy = { version_files = {'/etc/.freifunk_version_keep', '/etc/.eff_version_keep'}, old_files = {'/etc/config/config_mode', '/etc/config/ffeh', '/etc/config/freifunk'}, config_mode_configs = {'config_mode', 'ffeh', 'freifunk'}, fastd_configs = {'ffeh_mesh_vpn', 'mesh_vpn'}, mesh_ifname = 'freifunk', tc_configs = {'ffki', 'freifunk'}, wifi_names = {'wifi_freifunk', 'wifi_freifunk5', 'wifi_mesh', 'wifi_mesh5'}, } Packages -------- The ``site.mk`` is a Makefile which should define constants involved in the build process of Gluon. GLUON_SITE_PACKAGES Defines a list of packages which should be installed additionally to the ``gluon-core`` package. GLUON_RELEASE The current release version Gluon should use. GLUON_PRIORITY The default priority for the generated manifests (see the autoupdater documentation for more information). GLUON_LANGS List of languages (as two-letter-codes) to be included in the web interface. Should always contain ``en``. .. _site-config-mode-texts: Config mode texts ----------------- The community-defined texts in the config mode are configured in PO files in the ``i18n`` subdirectory of the site configuration. The message IDs currently defined are: gluon-config-mode:welcome Welcome text on the top of the config wizard page. gluon-config-mode:pubkey Information about the public VPN key on the reboot page. gluon-config-mode:reboot General information shown on the reboot page. There is a POT file in the site example directory which can be used to create templates for the language files. The command ``msginit -l en -i ../../docs/site-example/i18n/gluon-site.pot`` can be used from the ``i18n`` directory to create an initial PO file called ``en.po`` if the ``gettext`` utilities are installed. .. note:: An empty ``msgstr``, as is the default after running ``msginit``, leads to the ``msgid`` being printed as-is. It does *not* hide the whole text, as might be expected. Depending on the context, you might be able to use comments like ```` as translations to effectively hide the text. Site modules ------------ The file ``modules`` in the site repository is completely optional and can be used to supply additional package feeds from which packages are built. The git repositories specified here are retrieved in addition to the default feeds when ``make update`` it called. This file's format is very similar to the toplevel ``modules`` file of the Gluon tree, with the important different that the list of feeds must be assigned to the variable ``GLUON_SITE_FEEDS``. Multiple feed names must be separated by spaces, for example:: GLUON_SITE_FEEDS='foo bar' The feed names may only contain alphanumerical characters, underscores and slashes. For each of the feeds, the following variables are used to specify how to update the feed: PACKAGES_${feed}_REPO The URL of the git repository to clone (usually ``git://`` or ``http(s)://``) PACKAGES_${feed}_COMMIT The commit ID of the repository to use PACKAGES_${feed}_BRANCH Optional: The branch of the repository the given commit ID can be found in. Defaults to the default branch of the repository (usually ``master``) These variables are always all uppercase, so for an entry ``foo`` in GLUON_SITE_FEEDS, the corresponding configuration variables would be ``PACKAGES_FOO_REPO``, ``PACKAGES_FOO_COMMIT`` and ``PACKAGES_FOO_BRANCH``. Slashes in feed names are replaced by underscores to get valid shell variable identifiers.
