bodo_connect

• A library for mapping your hosts in the world wide web.
• A tool for connecting to any host of your map using ssh

It supports:

• Waking the host before connecting to it.
• Retry connection until ssh returns 0
• Automatic subnetwork detection for avoiding unneeded jump hosts

Installing

Install it with cargo install bodo_connect. Or build it simply by cloning this repo using cargo:

git clone https://github.com/topongo/bodo_connect
cd bodo_connect
cargo build --release
target/release/bodoConnect

NB

For legacy reasons, the binary for this crate is named bodoConnect and not bodo_connect.

Features

• cmd: (required for binary) actual binary in action
• serde: (required for binary) parse networkmap from json file
• log: enable logging (it doesn't automatically set to level Debug, it must be manually done if the cmd feature is off)
• wake: enable waking hosts by either making a GET request or executing the wol command on the master host of the target network.

Command Usage

Usage: bodoConnect [OPTIONS] <HOST> [EXTRA]...

Arguments:
  <HOST>      Host to connect to
  [EXTRA]...  Extra argument(s), if no -S or -R is used, it will be passed to the remote machine as command

      --networkmap <NETWORKMAP>  Select different networkmap.json file
  -w, --wake                     Wake host before connecting
  -t, --tty                      Pass -t parameter to ssh (force tty allocation)
  -d...                          Set verbosity level
  -q, --quiet                    Don't log anything

Networkmap

A little clarification on how a networkmap is structured:

• NetworkMap: a list of Subnets
• Subnet:
  • An physical/abstract local network. It is identified by its subdomain and it contains a list of hosts (and optionally by a static external ip address, eip).
• Host:
  • Identified by its name, that must be unique in the whole network map, it must contain:
    • An ip address
    • A port
    • A user
  • It can contain also an eport.
    • If set, the host becomes the subnet master, so it is considered to be always powered on and exposed for incoming ssh connection from foreign hosts
    • There can only be one master host per subnet
• Waker: an optional structure that defines how a host can be wakened. It supports:
  • http(s):
    • GET method
    • POST method (coming soon)
  • wol (wake on lan)
