Download the Client where the Server(in ur case its centaurus) runs at.
1. Start wireshark.
2. setup wireshark to log the networktraffic of your main ethernetcard
3. Connect to the sro server.
4. wireshark will instant create a huge log of ALL in and outcoming connections
5. find the needed informations
Check out the packets and you'll find the IP easy by urself.
If you have questions about how to use wireshark feel free to pm me.
But I think you can understand it without asking me.
You must be registered to see links
EDIT:
Short info about wireshark: It logs all the networktraffic which passes the selected networkcard.
Little tipp: If you have 2 monitors switch wireshark on the other monitor, before connecting to the wanted sro server start the tool (just start it a few seconds before pressing connect, to lower the amout of created logs!).
If you own a server by urself it is much easier. Connect to the server, and let wireshark log this connection. Than you search for your servers IP (which you already know) than you find out, in which packets the whished informations are hidden. Than do the same thing with the official sro server. You already know where to look at and you'll easy find the informations you need.
I am out for today, I can help you tomorrow if u need any help.
