connect_to_mesh.sh

This is a convenience tool for connecting your home computer to the mesh through an exitnode. It uses babeld and tunneldigger, just like a home node, so it's useful for testing and debugging exitnodes when you don't have access to a home node.

This script has been tested on Debian Stretch.

Dependencies

You need to install babeld and tunneldigger. See tunneldigger-lab for tips on compiling tunneldigger.

Create a config file

You'll need a tool that generates uuids, like uuidgen. Then you can do:

./create_config.sh $(uuidgen) > connect_to_mesh.config

Have a look at the connect_to_mesh.config file you just created. It should look something like:

# this will be your computer's mesh ip address
MESH_IP=<some-mesh-ip-address-here>

# tunneldigger identifies you with this id
UUID=<some-uuid-here>

# the location of the tunneldigger client executable
TUNNELDIGGER_PATH=../tunneldigger/client/tunneldigger

# the location of the babeld executable
BABELD_PATH=babeld

Edit the TUNNELDIGGER_PATH and BABELD_PATH variables by hand if you need to.

Connect

Now you can connect to any exitnode you want to:

sudo ./connect-to-mesh.sh <exitnode-ip-address>

You have to use sudo because connect_to_mesh.sh uses the ip command and babeld. And you must execute the script from the root of the repo directory because it uses some relative paths.

Example output:

sudo ./connect_to_mesh.sh 208.70.31.83
