After executing 'nmap -O -A 127.0.0.1', it returns some lines starting with 'OS:'. How to change it?

Look in the sourcecode for nmap, find how it figures out the Linux part, then rewrite your TCP/IP stack to not operate in a way nmap can detect.
Windows was made for looking at success from a distance through a wall of oversimplicity. Linux removes the wall, so you can just walk up to success and make it your own.

Yeah, but I don't know about linux system api at all.

Well, since nmap's fingerprint is based on the way the TCP/IP stack works, there's no real way except to rewrite the appropriate parts of said stack.

If that box isn't connected to the internet directly and behind a router it doesn't matter anyway.

However, I really need to avoid these messages. Can iptables do this work?

What messages, just the OS: fingerprint lines from nmap? Well, don't use OS detection or version scanning, read the manpage, grep -v the output...

Perhaps if you tell us what your goal is, rather than how you think you need to get there, we will be able to give more accurate answers

protecting against tcp/ip fingerprinting is possible. None of the methods used tries to modify tcp/ip stack.

Yes, only fingerprint. I want to prevent others from knowing the type of my OS.

So aren't you proud of the OS that you are using? ;-)

I like and rely on Arch but I have to hide myself because of some restrictions by my ISP.

That's weird...so they restrict you from using Linux?

No, they only restict routers. But perhaps they can't distinguish between a Linux PC and a router.

Just close all ports tightly with IP tables.., no one will get no reply thus not knowing whats hehind that IP.
