Hi
I would like to know if iptables is the correct tool to stop people from retriving data, such as what "NAME" of services I run (e.g vsFTPd) and other things like (Uptime 90.302 days (since Wed Jan 12 03:08:12 2005)) etc
And if so, how would you go about stoping the querys etc.
Does anyone know what service nmap talks to, to determine how long the box has been up and running for.
Just something I was thinking, kind regards
Brent Clark
