Net::Ping::HTTP inconsistencies

ruby-talk
1

I have multiple websites that are "up". That is, they are accessible via
the browser and return to the user content.

But...

require 'net/ping'

=> true

Net::Ping::HTTP.new('somewebsite.com').ping?

=> false

And, sometimes (I stress, _sometimes_):

require 'net/ping'

=> true

Net::Ping::HTTP.new('http://somewebsite.com').ping?

=> true

But then...

require 'net/ping'

=> true

Net::Ping::HTTP.new('http://somewebsite.com').ping?

=> false

Why the inconsistency? More importantly, how can I achieve consistent
results? It's maddening when a website is obviously functional and yet I
am told it's not.

system(%{echo "HEAD / HTTP/1.1\nHOST: www.rabbitcreative.com\n\n" | nc
http://www.rabbitcreative.com 80})

Really? Ruby's Net/* libraries suck, apparently.

Try this and see if you can determine why it's failing sometimes:

require 'net/ping'

http = Net::Ping::HTTP.new('http://somewebsite.com')

unless http.ping?
  puts "Ping failed: " + ping.exception
end

On what basis do you come to this conclusion? Maybe your webserver is not accepting all connection attempts to control the load. Maybe there are network issues. So far I have not seen evidence that there is something wrong with Ruby's net library. (Btw, which version are you using?)

net-ping isn't part of the Ruby standard library. There's a ping
library, but net-ping is a different beast.

Also, your problem did inspire me to make one change, which is to
alter the Net::Ping::HTTP class so that a URI without a path assumes
'/' for the path.
