Getting error "getaddrinfo: No such host is known. (Socke tError)" with mechanize gem

Ruby
1

I tried the below code:

require 'mechanize'

agent = Mechanize.new{|a| a.ssl_version, a.verify_mode = 'SSLv3',

OpenSSL::SSL::VERIFY_NONE}
page = agent.get “https://www.google.com/”
page=page.link_with(:dom_class => “button”).click()

But my bad getting the below error within my company,but the same was
running in my home desktop well. Any suggestion how to break
firewall/stie blocker and do the work in company also?

The same script ran perfectly on my personal machine,but not in my
company.

Could you please me to fix the same?

Thanks in advance

Maybe it’s the DNS setup on the company machine or how Ruby interacts
with DNS there.

Kind regards

The link is opened and workable on my each browser - ‘IE-9’,‘firefox’
both. But it is not with the script as mentioned above. So any work
around on that? Really it is painful for me. This Gem has good
fetures,but couldn’t use it. The same problem with “Nokogiri” also.

Thanks,

I didn’t get you. cloud you explain the syntax or give me a sample code
which you want me to do eliminate the error?

Thanks,

Nokogiri will not open remote connections. It’s just for parsing XML,
HTML and the like. Unless I am overlooking something.

Did you try to open a connection to that port using TCPSocket to
verify the underlying mechanics work?

Kind regards

Yes,We are using Proxy. Is the proxy only reason for that error? how I
need to set proxy with my script?

“mechanize” inside the “firewall”?

If your browser works you can use webdriver with the browser and its
default profile, and then let Nokogiri handle the HTML once you’ve
aquired the target page.
