I'm looking for the name of a tool I've used a long time ago, that for a given URL/website address would extract the technologies used for that site.
For example that the site is running Apache, using PHP 5.3, or IIS7 with asp.net, with vBulleting etc.
Does anyone remember what tool I'm referring to?
(P.S.: I know that "BuiltWith" has a service for this, I explicitly remember a tool in Kali Linux (or even back in BackTrack)
