From TTL of 64, you blindly conclude it’s Linux? This is BS article lol

common man TTL please have a basic understanding of networking please!!TTL means “time to live”. It is a value on an ICMP packet that prevents that packet from propagating back and forth between hosts ad infinitum. Each router that touches the packet decrements the TTL. If the TTL ever reaches zero, the packet is discarded. It’s also a measure of how many hops the packet took. If the TTL value started at, say, 128 and you see a value of 28, then there were 100 hops between the system where the packet originated and the final destination. My guess is that the initial TTL for the ping packets was 255, so the first ping traversal took 200 hops and the second took 9.

In reply to rama. Thank you for your comment. Suggested method will work only if default TTL value was not Changed. Also this method fail if Datacenter routing traffic to a different subnet. Nowadays more advanced tools available for OS detection... But almost every tool will fail if Banner grabbing done in server end..
