Question

For example I have a proxy server like this 91.229.248.75:8085 and if it work I should receive true or if it does not work I should receive false, how can I do it with RoR?

Answer 1

You can try this:

Install net-ping gem by

 gem install net-ping

Then use this to check proxy:

 require 'net/ping'

 Net::Ping::TCP.new('91.229.248.75', 8085).ping

For example:

 Net::Ping::TCP.new('www.google.com', 80).ping
