This server has nProtect Gameguard. Please kindly guide me how to extract useful clientinfo.xml for Poseidon server. Thank you.

@chrislong93 This is the clientinfo.xml of the Vietnam server.

You should use Wireshark to obtain the correct IP address and create server.txt

At present, there are some problems in charBlockSize, and you need to seek professional expert support.

Hey there, thanks a lot for your reply.

I posted my issue on a separate topic but long-story short, I've managed to acquire IP & Port & version & master_version but not recvpackets by any means available. Now im stuck at Timeout on Account Server.

Please refer to this link for a detail post: #3440 (comment)

Thank you very much !

client

We tried to block NP with a firewall
WINDOWS software is unable to run
if
Set up fortigate firewall virtual
Then connect to open RO through virtual windows10 IP ortigate, if open RO comes with NP open
That IP will open NP= =
As for the original breakthrough NP revision file, Aegis, this one has been greatly modified.
pass NP.zip

client can connect to localhost ?

In the previous version of nProtect gameguard, using xkore 0 will disconnect the connection because the special data packet of nProtect gameguard is not connected.
Our previous method was to use the main system to modify the clientinfo.xml in data.grf to connect to the local IP and open the client nProtect gameguard, nProtect gameguard will detect openkore as an illegal program under the same system, so we use a virtual machine to open Openkore xkore 2 connects to the IP of the same domain to avoid detection by nProtect gameguard, but the current situation seems that Gravity has used the new nProtect gameguard system to prevent the modification of files in data.grf, so this method cannot be used. I am currently looking for a way to see if I can connect to the same domain and use xkore2 /3 without modifying data.grf/clientinfo.xml

Do u have discord ?

I have the same question: Gravity has used the new nProtect gameguard system to prevent the modification of files in data.grf
Could it can connect to the same domain and use xkore2 /3 without modifying data.grf/clientinfo.xml?

Current I modify Ragexe.exe to load my xml file, and it can enter poseidon server.
But it also detection by nProtect gameguard for a period of time.
