Custom configurations should be supplied in a lixonet.conf file in the name=value format, such as your subnet. Additionally, a tinc keypair is also be required.

Generating keypairs for tinc (tinc.key):

Source: https://www.tinc-vpn.org/documentation/Generating-keypairs.html

Run: tincd -n lixonet -K

Configuration options

Location

A lixonet.conf file should be under each network directory you'd like to create. Create one directory for each mesh you'll be joining, under /etc/lixonet. If you want to join the teamlixo mesh for example, do this:

Create /etc/lixonet/teamlixo/lixonet.conf and specify at least all required options in this file.
Create or save /etc/lixonet/teamlixo/tinc.key

Available networks

Official networks:

Name	Git clone URL(s)	Subnet	ASN format	Administsration
teamlixo	http://git.team.lixo/lixonet/teamlixo.mesh.git	172.31.0.0/16	4206969XXXX	Manevolent, Nurd
colorado	http://git.team.lixo/lixonet/colorado.mesh.git	172.29.0.0/16	4206970XXXX	Manevolent

Format

All options are supplied in the name=value format on individual lines, i.e. name=test_name_lixo

Required options

You MUST specify these options, or Lixonet will not work.

git - The Git clone repository URL, used for peer configurations.
tinc_peer_name - The global neighbor name. Tinc and Bird use this to identify a peer in the network, and to exclude your own pre-packed config automagically from Tinc and BIRD dialing out so you don't connect to yourself over and over again.
tinc_peer_address - The router address to use. This is your Lixonet routing layer address: 172.xxx.0.xxx
network_address - The network address to use. This is your Lixonet routing layer address: 172.xxx.0.0 (especially take note of the last two 0's: 0.0 -- it MUST end with zeros corresponding to the network size)
bgp_asn - The BGP ASN to use. We usually follow the format 4206969XXX where XXX is the last octet of your address, zero-padded (i.e. 008 or 212)
internal_address - The internal address to use. MUST be unique to this Lixonet EE instance; if the address of the host is 172.31.16.2, you should NOT use that IP address, and instead pick another static address.
internal_gateway - The internal gateway to use. This is the IP address, directly upstream from the Lixonet EE router, that can be used as a next hop to reach your own subnets.

Non-required options:

General network options

global_prefix: global network prefix: defaults to 16.
router_prefix: router network prefix: defaults to 24. If you change this you SHOULD change netmask too.
netmask: router netmask: defaults to 255.255.255.0 (/24); SHOULD be the bitmask that corresponds to the router_prefix
internal_interface: the interface to route your OWN networks to. This should be the interface where your personal Lixonet subnets are reachable at, or in other words the interface at which the Lixonet EE router can send packets destined to networks you own. Defaults to eth0.
internal_subnet: the internal subnet that your Lixonet EE router is connected to, defaults to "internal_gateway/24".
vip: virtual IP: a virtual IP address to assign to the Lixonet EE router directly, aside from 172.31.0.8.

Tinc options

network_name - The name of the interface that Tinc should create when it's started. Defaults to lixonet. Set this for multiple networks.
tinc_bind_address - The address that Tinc should bind to to listen for incoming public Internet connections (i.e. 10.0.0.1). This is not the Lixonet router IP (i.e. 172.31.0.8). Use this if you have an eth1 that you don't want to use for binding tinc to, and would prefer to bind tinc exclusivley to eth0 instead. Defaults to internal_address.
tinc_bind_port - The Tinc server port to listen on. Defaults to 9994.
tinc_connect_to - A comma-separated list of well-known/pre-defined hosts to connect to (i.e. denco_mane_lixo). If not supplied, this is automatically set to all core routers that aren't yourself (name).

BGP options

For options we expose here, for information see: https://bird.network.cz/?get_doc&v=20&f=bird-6.html#ss6.3

bgp_path_metric: Enable comparison of path lengths when deciding which BGP route is the best one (0 or 1): defaults to 1
bgp_aigp: BGP AIGP state (enable, disable, or originate): defaults to originate (see BIRD documentation)
bgp_rpki_retry: If RPKI cache data cannot be obtained, the time period in seconds between a failed query the next attempt. Defaults to 90.
bgp_rpki_refresh: How long to wait in seconds before attempting to poll RPKI cache data after the last successful poll. Defaults to 900.
bgp_rpki_expire: How long to keep any records locally cached before they are deleted. Defaults to 172800 (2 days).
bgp_rpki_known_hosts: The file path for the SSH key known_hosts file to use when validating remote RPKI hosts. Defaults to /etc/bird/rpki/known_hosts (provided by Lixonet; don't change this unless you need to!).
bgp_passwd_*: The password for a specific BGP peer (i.e. bgp_passwd_denco_mane_lixo). If not specified, no password is used for the host.
bgp_routes: A comma-delimited list of routes to advertise over BGP. If not specified, no routes are propagated.

BIND options

These settings are optional, and are already defaulted to general network common practices.

bind_forward_address: The overridden DNS server IP address to forward all requests for your own domain to. Defaults to the value of internal_gateway, which is proper in most if not all cases. Your BIND zone is automatically converted from your tinc_peer_name (i.e. lkwco_mane_lixo becomes lkwco.mane.lixo).
tld: The network-wide TLD to use. Defaults to lixo.

Setup, Installation, and Updating

Prerequisites/Setup:

eth0 is the LAN or WAN interface supporting external routing, DNS, etc., and is the bridged interface to a router that will statically route the entire desired network subnet (i.e. x.x.0.0/21) through it. You may also have an eth1 (and so on, so forth) that you statically configure for your entire, wide subnet (i.e. x.x.0.0/21) if you want to use two physical adapters. If you do have more than one interface, make sure that internal_gateway is set to the router IP address that can route your personal Lixonet subnets, and not your WAN gateway (unless they're the same).
tun and tap are in /etc/modules to load at boot (https://www.cyberciti.biz/faq/linux-how-to-load-a-kernel-module-automatically-at-boot-time/) and the system has been rebooted afterwards.
IPv4 forwarding is on: sysctl -w net.ipv4.ip_forward=1
Clone this repository: git clone <url>
mkdir /etc/lixonet/(mesh)/
Fill out /etc/lixonet/(mesh)lixonet.conf (see: Configuration options)
Supply /etc/lixonet/(mesh)/tinc.key

Install/Update:

You should no longer need to run build.sh directly. Instead, use a "self-configuring" Docker container to make your life easier.

Clone or navigate to a cloned repository folder you already have.
Run git clean -f -d && git reset --hard && git pull origin master && docker build -t lixonet-ee . && docker run --rm -it -v /etc/bird:/etc/bird/ -v /etc/tinc:/etc/tinc -v /etc/bind:/etc/bind -v /etc/lixonet:/etc/lixonet -v /var/run/docker.sock:/var/run/docker.sock lixonet-ee
