USAGE:

${chalk.red('node network')} ${chalk.italic.red('[options]')}

OPTIONS:

${chalk.italic.red('--network-signing-account')} ${chalk.bold.red('text')}

A specific P2P network signing account to start using. This overrides the default "P2P-Network-Node-1"

${chalk.italic.red('--include-local-networks')} ${chalk.bold.red('true/false')}

Do you want to include all local networks nodes?

${chalk.italic.red('--exclude-localhost')} ${chalk.bold.red('true/false')}

Do you want to exclude all localhost and 127.#.#.# nodes?

${chalk.italic.red('--only-me')} ${chalk.bold.red('true/false')}

Do you want to limit the network to only your network nodes?

${chalk.italic.red('--users')} ${chalk.bold.red('text')}

Repeat for each username you want to connect to

EXAMPLES:

############################################################

# To specify a network node on your profile called

# ${chalk.italic.red('Local-Network-Node')}

############################################################

node network --network-signing-account Local-Network-Node

############################################################

# To limit the network connections to only my network nodes,

# in order for this to work you will need at least 2 network

# nodes setup

############################################################

node network --onlyMe

############################################################

# To exclude all local networks from the connection pool set

# the ${chalk.italic.red('--include-local-networks')} to ${chalk.bold.red('false')}. This is useful as

# many users will use localhost or a 192 style address when

# testing their own network setup and this will create

# multiple connections self referencing connections.

############################################################

node network --include-local-networks false

############################################################

# To create a network pool with a friend or some specfic

# users then add as many ${chalk.italic.red('--users <USER>')} options as you need.

# This will limit the network connection pool to only these

# user networks.

############################################################

node network --users <USER1> --users <USER2>

############################################################

# The options ${chalk.italic.red('--users')} and ${chalk.italic.red('--include-local-networks')} can also

# be combined so you do not create duplicate local network

# connections. Providing these users are not on your local

# network

############################################################

node network --users <USER1> --users <USER2> --include-local-networks false
