Working Methods might be detected utilizing Ping Command, Ping is a pc community administration software program utility, which used to search out the Availability of a bunch on an Web Protocol (IP) community.

Ping operates by sending Web Management Message Protocol (ICMP) Echo Request packets to the goal host and ready for an ICMP Echo Reply.

TTL is just meant, how lengthy a resolver is meant to cache the DNS question earlier than the question expires and a brand new one must be carried out.

These TTL values differ between the Working system. Right here you discover TTL worth for Vary of servers. Reference subinsb.

Working Methods might be detected utilizing Ping Command

We must always run the traceroute command first to find out the hops between the Goal and the vacation spot.

Operating Systems can be detected using Ping Command

TTL worth is TTL=53, By making the Sum of TTL worth and variety of hops we will outline the working system (53 + 11 = 64), we will conclude that there’s a Linux Machine Operating.

This how Working Methods might be detected utilizing Ping Command.
