Garda Posted February 4, 2013 Share Posted February 4, 2013 I have been having a bit of fun with the search engine [url"http://www.shodanhq.com]Shodan[/url]. It was mentioned in this episode of Hak5 and in a few old discussions in these forums. Unlike other search engines it indexes technical information about services that run on the Internet. For example, it lets you search by web server type, or by strings in the headers sent when sessions are initiated. For example, I was kind of interested to know if there are a lot of people with Internet facing instances of the http://www.rejetto.com/hfs/'>HFS web server. If you access a web server via telnet and ask for /index.html (I'm not 100% sure what the proper http command is to get the root web page, I need to look it up), you get a few http headers and then the start of the 404 error page. (see below) garda@localhost:~$ telnet localhost 8080 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. GET /index.html HTTP/1.1 404 Not Found Content-Type: text/html Accept-Ranges: bytes Server: HFS 2.2f <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> <style> Quote Link to comment Share on other sites More sharing options...
