Hi astaro and users.
Today i tried nmap V.2.54beta with -O option.
I am suprised of the information I got from nmap.
NMAP use TCP/IP stack (different) scans.
Remote operating system guess: Linux Kernel 2.4.0 - 2.4.5 (X86)
Uptime 3.142 days (since Fri Sep 7 13:58:18 2001)
NMAP can even guess how long uptime and kernel version of a firewall. I think it should be good if we can hide it or somehow.
Or maybe other suggestions? I am not sure, but I feel insecured!
thax!
