# Network Stack will create a shared instance, that other
# programs can communicate with. Only the shared instance
# opens all the configured interfaces directly, and other
# local programs communicate with the shared instance over
# a local socket. This is completely transparent to the
# user, and should generally be turned on. This directive
# is optional and can be removed for brevity.

share_instance = Yes


# If you want to run multiple *different* shared instances
# on the same system, you will need to specify different
# shared instance ports for each. The defaults are given

# don't need them.

# On systems where running instances may not have access
# to the same shared Reticulum configuration directory,
# it is still possible to allow full interactivity for
# running instances, by manually specifying a shared RPC
# key. In almost all cases, this option is not needed, but
# it can be useful on operating systems such as Android.
# The key must be specified as bytes in hexadecimal.

# You can configure Reticulum to panic and forcibly close
# if an unrecoverable interface error occurs, such as the
# hardware device for an interface disappearing. This is
# an optional directive, and can be left out for brevity.
# This behaviour is disabled by default.

# When Transport is enabled, it is possible to allow the
# Transport Instance to respond to probe requests from

[interfaces]

  # This interface enables communication with other

  # need any functional IP infrastructure like routers
  # or DHCP servers, but will require that at least link-

  # should be enabled by default in almost any OS. See
  # the Reticulum Manual for more configuration options.

    # IP interfaces.
