Using Ping Command: How Important in a System Communication?

The Operating Systems can be detected and find out if you can "talk" to them using the Ping command. Ping is a computer network administration software utility used to find the availability of a host in an Internet Protocol (IP) network.

Ping works by sending Internet Control Message Protocol (ICMP) Echo Request to the host and waiting for an ICMP Echo Reply.

Ping

The TTL means how long it takes a parser to temporarily save the DNS query before the query ends and a new one has to be created.

These TTL values ​​are different in an operating system. Here you can find from a TTL value for a range of servers.

Operating systems can be detected using a Ping command

We must first execute the command traceroute to determine the hops between Target and the destination.
