CI

Microlib to generate ICMP ping requests.
Avoids sudo requirement of using raw sockets by shelling out to ping and thus pinger has an implicit dependency of ping.

Installation

  1. Add the dependency to your shard.yml:

    dependencies:
  pinger:
    github: spider-gazelle/pinger

  2. Run shards install

Usage

require "pinger"

hostname = "www.duckduckgo.com"
pinger = Pinger.new(hostname, count: 3)

pinger.ping # => true / false
puts {
    host: pinger.ip,
    pingable: pinger.pingable,
    warning: pinger.warning,
    exception: pinger.exception
}

Or if you would like an error raised


require "pinger"

hostname = "www.doesnotexist.com"
pinger = Pinger.new(hostname, count: 3)

pinger.ping! # => self / raise pinger.exception

Todo

  • utilise Crystal::Config.default_target rather than shelling out to uname
