torspray 0.1.5

A console utility to bring up new Tor bridges easily

torspray

A console utility to bring up new Tor nodes easily

Current progress

Works:

• key generation
• node management commands
• file copy
• command execution on one or all nodes
• automatic configuration of tor on the node

Works in progress:

• meaningful statistics
• ability to compile torspray to a standalone executable
• password login support

Why?

This tool is meant to empower less tech-savvy users to be able to quickly and effortlessly bring up tor nodes to help out the network in times of crisis.

What do I need?

• You will need a virtual machine (VM) with Debian 11 at a hosting provider. I use Hetzner.
• On installation, specify the ssh key that torspray generates. Passwords support doesn't yet work unfortunately.
  • if you don't remember, run torspray pubkey
• Once the server is provisioned you can add it to torspray to manage

Bugs

The software is in very early stages if you encounter problems, open a github issue or DM me on twitter @gergely_kalman

Installation

$ pip install torspray

Usage example

initialization:

$ torspray init [e-mail]
[+] Initializing torspray directory: /home/synapse/projects/development/torspray/code/.torspray

Adding nodes, VMs might take time to come up, so have to retry:

$ torspray add testnode 65.108.217.166
[+] Adding server 65.108.217.166, password: None
[-] Failed to reach server, try again later

$ torspray add testnode 65.108.217.166
[+] Adding server 65.108.217.166, password: None
We have:
	username root
	hostname debian-2gb-hel1-1

Listing nodes:

$ torspray list
[+] Servers in the DB:
	testnode: {'address': '65.108.217.166', 'hostname': 'testnode'}

Installing tor bridge on node (log was cut short):

$ torspray spray testnode
[+] Spray verifying versions
$ dpkg --print-architecture
amd64
	version: Debian GNU/Linux
	codename: bullseye
	arch: amd64
[+] Spray enabling updates
...
$ systemctl restart tor.service

Testing execute on node 'testnode'

$ torspray node-exec testnode 'hostname'
[+] Execing: hostname
testnode:
debian-2gb-hel1-1

Showing pubkey because I forgot:

$ torspray pubkey
