Block information



  • i use pfsense 2.3.1
    and squid3

    when i go to this site http://www.whatsmyip.org/

    i get my ip and Details on my computer (See attached image) where it says Your User Agent

    can i block this Details ?



  • Why do you want to suppress the agent info?

    The agent string is used at web servers to make websites fit and optimized to your browser.

    If you want to suppress it anyway, you can use browser add-ons like User Agent Overrider or User Agent Switcher.



  • Is it possible to do it with pfsense ?
    so all it will be block for all the computers in the net ?



  • No, not by pfSense itself. This is part of HTTP. Maybe it can be changed or suppressed on a proxy like squid. I don't know.
    There is a special topic for that in the forum: https://forum.pfsense.org/index.php?board=60.0

    blocking that is going to break many a website, or at min make sites not look right.

    Are you sure ?

    When I had Squid 2 installed
    i marked these two

    Disable X-Forward
    Disable VIA
    

    and the site did not see these details (ip,resolution,system,etc etc)
    And browsing was fine

    He's right. You didn't disable the user agent by doing that, that just disables the headers that Squid adds, so remote sites won't see you're going through a proxy.



  • so how this details Were blocked ?

    They are part of the HTTP GET browser call (Yep, it's your browser who tells the web server who / what / where / …. so using a less noisy browser will help here)
    Squid probably dives into the IP packets and removes them on the fly ...
