Identifying Which Operating System  Using Weborion Free Tools

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

 

Now as you can see, it shows some TTL value which is currently 57, TTL(Time To Live) means how long a resolver is supposed to cache the DNS query before it expires and a new one needs to be done.

Here is the complete chart where you can see all TTL values of all servers.

You can get the short version of default TTL values by this table :

For Unix/Linux – TTL Value = 64
For Windows – TTL Value = 128
For Solaris/AIX – TTL Value = 254

Now to find the OS you need to calculate two things, one is PING TTL value and second is tracert hops.

For Tracert, you can use this below Url:

Tracert basically determine the hops between the Target and the destination.

So as you can see, the total No. of Hops are 7 and our TTL value is 57, by making the sum of TTL value + a number of hops results  57+7 = 64, which means the server is a Linux  Machine.
