Step 5: Analyze

The Ragnarok Online client sent some data to the Ragnarok Online server. This data contains all the information we need. (In this example, I used the iRO client to login. All example information here applies only to iRO Chaos/Loki.)


The text under the Destination column is the IP address and the port number of the Ragnarok Online server.

In this case, the IP is 38.144.194.2, and the port number is 6900.


The column in the middle (starting from "64 00") shows the bytes that the Ragnarok Online client tried to send to the server. The third byte is the server version number. However, it's in hexadecimal. You need to convert it to a decimal number, by using a calculator that supports hexadecimal.

In this case, the server version number is 18 (hexadecimal 12 is decimal 18).


The last byte is the master version number. This number is also in hexadecimal. In this case, our master version number is 1.

So the information that we have gather in this example is as follows:


    IP: 38.144.194.2 Port: 6900 Master version number: 1 Version number: 18

In Kore's configuration file, we put this:
