# DefaultUsername specifies the default username to use for
# authenticating to tunnelbroker.net.
# It is optional, as the username can be specified for each Tunnel,
# but at least one or the other *must* be provided.
# This makes it easier if you have multiple tunnels under the same account
# (as possible in higher levels of HE IPv6 certification).
# If a username is specified in Tunnel.Username, it will be used.
# If not (and, of course, DefaultUsername is specified), then
# DefaultUsername will be used for that Tunnel.
DefaultUsername = "default_user"
# If SingleTunnel is true, each Tunnel below will be run in order instead of
# concurrently.
# If there is any concern about race conditions (e.g. the same service being
# restarted by multiple tunnels, etc.), then it is HIGHLY RECOMMENDED
# you set this to true.
SingleTunnel = true
# CacheDbPath is entirely optional.
# If not provided, results will be cached in RAM (and thus lost on reboot
# or program termination/restart).
# (This can be explicitly specified by using the value ':memory:'.)
# If provided, it should be a path to a file to use as a SQLite3 database
# that holds cached information.
# The information that is cached contains only:
# * each Tunnel.TunnelID
# * the associated tunnelbroker.FetchedTunnel
# * a CRC32 of all configuration (as defined in this file) for that Tunnel
# The UpdateKey and other configuration defined here (aside from
# Tunnel.TunnelID, and Tunnel.ExplicitClientIP if specified) are
# NOT stored.
# Any tunnel present in a persistent cache DB but *not* defined in the
# running GoBroke config will be removed.
# Note that the cache DB primary key is based on the Tunnel.TunnelID,
# as one cannot define multiple client endpoints for the same tunnel.
CacheDbPath = '/var/cache/gobroke.db'
# CacheDbPerms specify the permissions for CacheDbPath.
# This directive is completely optional, and is
# ignored if CacheDbPath is ":memory:" (or unspecified).
# If not specified (and CacheDbPath is persistent),
# then the runtime user's umask and effective UID/GID
# is used if creating a new database file.
# If the file exists and permissions are defined, they will
# be enforced.
# If the file exists but no permissions are defined, they
# will be left as-is.
[CacheDbPerms]
# Permissions are/may be defined for both the file being written
# and the parent directory (see below).
[CacheDbPerms.File]
# The User is optional.
# If unspecified, the default behavir mentioned above is performed.
# If specified as an empty string, the runtime EUID is enforced.
# Otherwise it may be a username or a UID (checked in that order).
User = ""
# Group is also optional, and follows the same logic except
# for EGID/groupnames/GIDs.
Group = ""
# Mode is optional also.
# It *must* be equal to the octal mode bits (e.g. it must be an
# unsigned integer), but may be represented in multiple ways.
# e.g.:
# Mode = 0o0600
# Mode = 0o600
# Mode = 0x0180
# Mode = 0x180
# Mode = 0b110000000
# Mode = 384
# All evaluate to the exact same value in TOML:
# https://toml.io/en/v1.0.0#integer
# For consistency with `chmod(1)`, it is recommended to use the
# octal representation (0o0600 or 0o600 above).
# If you need help determining what number you should actually use,
# you can use the calculator here:
# https://rubendougall.co.uk/projects/permissions-calculator/
# (source: https://github.com/Ruben9922/permissions-calculator )
# (Supports "special" bits)
# or here:
# https://wintelguy.com/permissions-calc.pl
# (beware of ads)
# (provides an explanation of the bits)
# Or see https://en.wikipedia.org/wiki/Chmod
Mode = 0o0600
# Dir permissions specifiy permissions/ownership of the parent directory of the cache DB.
# The same rules, logic, behavior, etc. as in CacheDbPerms.File apply here.

## Tunnels ##
#############
# Each Tunnel represents a single tunnelbroker.net tunnel configuration.
# Note that each Tunnel is run concurrently. If this is undesired due to
# potential race conditions, set the root-level directive SingleTunnel
# to true.
[[Tunnel]]
# The TunnelID can be found by logging into https://tunnelbroker.net/ and,
# at the "Main Page" that loads when logging in, clicking on the desired
# tunnel name.
# The tunnel ID is then displayed in both the URL bar:
# https://tunnelbroker.net/tunnel_detail.php?tid=<TunnelID>
# And as the first line on the first tab ("IPv6 Tunnel" tab),
# labeled "Tunnel ID".
TunnelID = 123
# If you wish to use a different or explicit "Client IPv4 address",
# this can be specified via ExplicitClientIP.
# If it is empty or is not specified, the public IP of this host will be determined
# via an external service.
# This *must* be an IPv4 address (if specified).
ExplicitClientIP = '203.0.113.1'
# If you have specified a custom MTU under the "Advanced" tab for this tunnel,
# you can set this value here.
# If you have not set a custom one, leave this option unspecified;
# the default (and maximum allowed), 1480 MTU, will be used in that case.
MTU = 1450
# The Username field is optional IF DefaultUsername was specified.
# This also allows you to specify tunnels from different accounts
# by providing a tunnel-specific username.
Username = "specific_user"
# The UpdateKey can be found under the "Advanced" tab on your tunnelbroker.net
# tunnel's page, labeled "Update Key".
# Your real token is likely to be a bit longer and more random.
# This token is used to not only update the client-side tunnel IP but also to
# query the HE Tunnelbroker "API" (it's really just a single endpoint)
# to get the tunnel configuration.
UpdateKey = "abcdef"

## Config Templates ##
######################
# Each ConfigTemplate consists of a path to a template file and a destination
# file at the bere minimum. In addition, Commands may be provided.
# Any paths leading up to Destination that don't exist will (attempt to be)
# created.
# The template is always rendered in memory, but the destination is only written
# if:
# * The Destination doesn't exist
# * The Destination differs from the buffered rendering of the template
# Commands are optional, and are a list of commands to be run.
# Their running may be restricted to only if the tunnel information/IP
# information has changed, always run, or the inverse of all conditions.
[[Tunnel.ConfigTemplate]]
# Template points to where the template file can be found.
# It must be in a Golang text/template syntax/format; see:
# https://pkg.go.dev/text/template
# Refer to the library's definition of the tunnelbroker.FetchedTunnel struct;
# this is the object that is passed to the template.
Template = "/etc/gobroke/tpl/dnsmasq/ra_dhcpv6.conf.tpl"
# Destination is the file to write to.
# It will only be written to if:
# * The path does not exist
# * The path exists but is different from the in-memory rendered buffer
# An attempt will be made to create any leading components that are not
# present.
# It is recommended to enforce permissions/ownership of these via the
# Commands.
Destination = "/etc/dnsmasq.d/ra_dhcpv6.conf"

## Config Template Permissions ##
#################################
# Permissions can be defined for the Destionation file.
# They are completely optional, in which case the default umask, user,
# group, etc. for the runtime user will be used, and permissions/ownership
# will not be enforced for existing Destination files.
# It follows the same syntax, logic, behavior, etc. as CacheDbPerms.

## Config Template Commands ##
##############################
# Commands are a collection of commands to run as part of this template
# run.
# Multiple Commands may be specified; they will be run in the order specified.
# The below Command would be equivalent to:
# SOMEENV=SOMEVAL /usr/local/bin/somecmd -f foo
# on the shell.
[[Tunnel.ConfigTemplate.Command]]
# ProgramPath should be the absolute path to the binary to run.
# It behaves as an (os/)exec.Cmd.Path (https://pkg.go.dev/os/exec#Cmd),
# It is recommended to use an absolute path.
ProgramPath = '/usr/local/bin/somecmd'
# Args are optional for a Command.
# They should conform to the rules for (os/)exec.Cmd.Args.
Args = [
'-f', 'foo',
]
# If IsolatedEnv is false (the default), the runtime environment variables
# will be applied to the command.
# If true, *only* the EnvVars, if specified, will be used for the spawned
# command (an empty environment will be used if IsolateEnv is true and
# no EnvVars are specified).
IsolatedEnv = false
# If provided, EnvVars can be used to add/replace environment variables.
# They should conform to the rules for (os/)exec.Cmd.Env.
# Whether they are added to/selectively replace or completely replace
# the current runtime environment variables depends on how IsolateEnv
# is configured.
EnvVars = [
'SOMEENV=SOMEVAL',
]
# If OnChange is true, this Command will run *only if SOMETHING CHANGED*.
# (e.g. a /48 was added to the tunnel, the client IP is different, etc.)
# If false, this Command will run *only if NOTHING CHANGED*.
# If unspecified, the default is to always run this command regardless
# of change status.
# The very first (successful) run of a Tunnel is considered a "change",
# as is writing out this template to disk as a new file.
OnChange = true
# By default, this Command will be run literally/as-is.
# However, in some cases it may be useful to dynamically template out
# commands to run.
# If IsTemplate is set to true, then this Command.ProgramPath, each
# of the Command.Args, and each of the Command.EnvVars will be
# treated as Golang text/template strings as well, and will also
# be passed a tunnelbroker.FetchedTunnel.
# Note that if IsolateEnv is false, runtime/inherited environment
# variables will *not* be templated.
# It is recommended to not enable this unless necessary as it can add
# a non-negligible amount of resource overhead/execution time.
IsTemplate = false

#####################
## Tunnel Commands ##
#####################
# Each Tunnel also supports its *own* commands. The syntax, spcification,
# behavior, etc. is the same as the Tunnel.ConfigTemplate.Command.
# These are executed after all Tunnel.ConfigTemplate (if any) are executed.
# This is particularly useful for consolidating service restarts.
[[Tunnel.Command]]
ProgramPath = 'systemctl'
Args = [

# Multiple tunnel configurations are supported as well.

######################
## General Commands ##
######################
# Command items may be specified at the root level as well.
# The syntax is like all other Commands items, with two exceptions:
# * There is no templating performed...
# * As such, there is no IsTemplate directive for these.
# A root-level Command is run after all tunnels complete.
# The OnChange directive is true if any Tunnels result in any changes.
