Hi all, I need to add this option to kernel in order to defeating Nmap OS-Fingerprinting. My system is running as Web Server and also it is the gateway on the network. I want to know if setting this option has any side effects on other parts of the system? Is there any situation that SYN and FIN bits are set both in TCP packets? Is it a normal situation? Any helps or comments are really appreciated.
