Determining OS type with a Ping

TTL=58 = VMware ESXi host
TTL=64 = *nix - the hop count so if you’re getting 61 then there are 3 hops and its a *nix device. Most likely Linux.
TTL=128 = Windows - again if the TTL is 127 then the hop is 1 and it is a Windows box.
TTL=254 = Solaris/AIX - again if the TTL is 250 then the hop count is 4 and it is a Solaris box.
