| Security and Privacy Sadly, malware, spyware, hackers and privacy threats abound in today's world. Let's be paranoid and secure our penguins, and slam the doors on privacy exploits. |

security related ,,but a bit funny
Unsolicited Packets: RECEIVED (FAILED) — Your system's personal security countermeasures unwisely attempted to probe us in response to our probes. While some users believe that "tracking down" the source of Internet probes is useful, experience indicates that there is little to gain and potentially much to lose. The wisest course of action is to simulate nonexistence — which your system has failed to do. Your counter-probes immediately reveal your system's presence and location on the Internet. ,,,,,,,,,,,,,,,,,,,,,,,,lol is there a way for me to stop my system from probing others ?

I don't know enough about ip-tables to be of any help, but what the message is telling you that grc.com "probed" you (probably with an ICMP packet), and your system responded with a counter-probe - veryfying it's existence. It's much safer to just drop probes - that essentially makes your system a "black-hole." It appears (to the prober) that you don't even exist... I believe Firestarter has this capability. I know ip-tables does, but in all honesty, I could not tell you how to set it up...

I wonder what they did. Sent pings or other packets? Did you use a scanner like nmap?
If you turn on a firewall, you won't respond to requests. Main Menu > System Settings > Security Level. Enable the firewall.

yeah when someone pings you, you bounce the ping back. they're telling to just to drop the pings. Thus no one can even see that you're out there.
in your iptables you want to drop packets instead of rejecting packets. Thus you'd be unseen and passed over

Not necessarily - there are several programs that will help you set up your firewall without you having to learn the ins and outs of iptables... I've used Guarddog before (I have a WAP/Router now instead of a PC-based router) and was extremely pleased at how simple it made setting up firewalls.
