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.tnp.services.ffeh'}
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).
autoupdater : package

Configuration for the autoupdater feature of Gluon.

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
      }
    }
  }
}
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.

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 <!-- empty --> as translations to effectively hide the text.
