Hi,

I participate in a discussion board hosted in America. Yesterday, the
sig line of one of the other participants fed me back my Internet
address, the operating system, linux, the browser, Opera, I was using,
and the company name of my ISP.
All that is happening there is that they are including a <img> link to
an image generator script on the danasoft.com server, which causes your
browser to make an HTTP request to that machine, which then finds out
all that information from the TCP connection and the headers your
browser sends. Every website you go to will get this information, often
several times (once per page, stylesheet, and image etc you download).
Am I making a fuss about nothing? Is there any linux software that I can
install that will prevent this behaviour?
One course of action would be to use an adblock-style extension, if
there is one for Opera, to deny requests to that domain. Alternatively
you could put something like:
127.0.0.1 www.danasoft.com
into your /etc/hosts file, which will redirect any request for that
domain to your own machine, which will likely fail and you won't get the
image. You might need to change the name of the server. It's actually
nothing to worry about, in my view. It is rather obnoxious though.
