ruby ping for 1.9.1

Question

I want to ping a site in my ruby code and saw that net-ping was a nice library to do this with. Unfortunately, when I tried to gem install net-ping I got the following error:

Answer 1

You can always do this and use regexps to parse the result or just check the exit status:

ping_count = 10
server = "www.google.com"
result = `ping -q -c #{ping_count} #{server}`
if ($?.exitstatus == 0) do
  puts "Device is up!"
end

Ping return values that you can check against:

The ping utility returns an exit status of zero if at least one response was heard from the specified host; a status of two if the transmission was successful but no responses were received; or another value (from ) if an error occurred.
