Configuration

Gateways

There are two ways to configure an SSH gateway. Both can be used together, but at least one must be defined:

• Define a default_gateway section in your configuration file.
• Define a gateways section in your conifguration file.

The default_gateway is a map containing these keys:

• host: hostname or IP address of gateway (required).
• port: SSH port on gateway (default: 22).
• user: Username on gateway to connect with (default: $USER).

The gateways section is also a map, but each key represents a named gateway, and each gateway is configured using the same parameters as default_gateway.

Each named gateway can be referred to in the gateway field for each tunnel.

# config.yml

default_gateway:
  host: gateway.example.com

gateways:
  aws:
    host: 111.111.111.111
    user: ubuntu
  azure:
    host: 222.222.222.222
    user: william

Tunnels

The tunnels section is a map where each key represents a named tunnel. Each tunnel can be configured using the following parameters:

• host: The remote host to connect to from the gateway.
• remote: The remote port to use for forwarding.
• local: The local port to bind to (defaults to the remote port).

# config.yml

default_gateway:
  host: gateway.example.com

gateways:
  aws:
    host: 111.111.111.111
    user: ubuntu

tunnels:
  my_host:
    local: 1234
    host: my.host.example.com
    remote: 4567
  other_host:
    gateway: aws
    local: 1111
    host: other.host.example.com
    remote: 5555
