Debian Squeeze Security (Iceweasel)

[consul tores <consultores1@gmail.com>]

Hello

I have been tracing this problem for days, and at the end; the Squeeze
laptop which i use to remote/local administration is sending www
signal to web servers every time that i open Iceweasel to do other
things. It does not matter if i connect by ssh or not during that
session. Every time use public ip.

At OpenBSD web server side:

my_public_ip - - [15/May/2011:03:28:40 -0700] "GET / HTTP/1.1" 200 2259
my_public_ip - - [15/May/2011:08:17:24 -0700] "GET / HTTP/1.1" 200 2259
my_public_ip - - [15/May/2011:08:17:40 -0700] "GET / HTTP/1.1" 200 2259
my_public_ip - - [16/May/2011:01:20:44 -0700] "GET / HTTP/1.1" 200 2259
my_public_ip - - [16/May/2011:02:37:55 -0700] "GET / HTTP/1.1" 200 2259
my_public_ip - - [16/May/2011:02:43:48 -0700] "GET / HTTP/1.1" 200 2259
my_public_ip - - [16/May/2011:02:48:08 -0700] "GET / HTTP/1.1" 200 2259

What could be causing that? Where could i see deeper?

PS:
The OS does not seem compromised.

Thanks.
