ok so i run an nmap scan to my other pc in my lan and here are the results. HOw to make it more secure so it doesnt give away all that info? I am behind a hardware firewall.
nmap -vv -sS -O 192.168.0.5

The SYN Stealth Scan took 1.67s to scan 1663 total ports.
For OSScan assuming port 22 is open, 1 is closed, and neither are firewalled
Host 192.168.0.5 appears to be up ... good.
