I have tried many times and in different ways but still cannot extract the client recvpackets. I have uploaded the client.exe

I beg for your help in connecting to this RO with this following information.

The website is www.rokvn.com

ip 103.9.159.142
port 7900
master_version 93
version 53
serverType kRO_RagexeRE_2013_08_07a (unsure)
serverEncoding Western
recvpackets
charBlockSize 144
addTableFolders kRO/RagexeRE_2013_08_07a;pserver;translated;translated/kRO_english;kRO

Your client type/servertype is 2015_10_29, but you can use the latest one or the closest

Save this file, recvpackets.txt
and put on the tables/kRO/RagexeRE_2013_08_07a folder.

Code: Select all

and save this code with name "ench.pl" without quote mark.
and put on your openkore Plugins folder

Code: Select all

package scridbblie;

use Network::Send;
use Log qw (warning message debug error);
use Globals qw(%config $encryptVal $bytesSent $conState %packetDescriptions $enc_val1 $enc_val2 $char $masterServer $syncSync $accountID %timeout %talk);

Plugins::register("Encryption private", "Encrypt header", \&unload);

sub unload {
warning "Unloading\n";
}

sub fp {
my $self = shift;
      open F, "<plugins/xh.txt" or die "Xh.txt file not found";
      my @keys;
      @keys = <F>;
      close (F);
                if (scalar @keys > 1) {
      $self->cryptKeys(@keys);
                } else {
                warning "Ench plugin requires keys to work...";
                }
}

sub load {
my ($self, $r_message) = @_;
   my $messageID = unpack("v", $$r_message);
   fp($self);
   if ($self->{encryption}->{crypt_key_3}) {
      if (sprintf("%04X",$messageID) eq $self->{packet_lut}{map_login}) {
         $self->{encryption}->{crypt_key} = $self->{encryption}->{crypt_key_1};
      } elsif ($self->{net}->getState() != Network::IN_GAME) {
         # Turn off keys
         $self->{encryption}->{crypt_key} = 0; return;
      }
         
      # Checking if Encryption is Activated
      if ($self->{encryption}->{crypt_key} > 0) {
         # Saving Last Informations for Debug Log
         my $oldMID = $messageID;
         my $oldKey = ($self->{encryption}->{crypt_key} >> 16) & 0x7FFF;
         
         # Calculating the Encryption Key
         $self->{encryption}->{crypt_key} = ($self->{encryption}->{crypt_key} * $self->{encryption}->{crypt_key_3} + $self->{encryption}->{crypt_key_2}) & 0xFFFFFFFF;
      
         # Xoring the Message ID
         $messageID = ($messageID ^ (($self->{encryption}->{crypt_key} >> 16) & 0x7FFF)) & 0xFFFF;
         $$r_message = pack("v", $messageID) . substr($$r_message, 2);

         # Debug Log   
         debug (sprintf("Encrypted MID : [%04X]->[%04X] / KEY : [0x%04X]->[0x%04X]\n", $oldMID, $messageID, $oldKey, ($self->{encryption}->{crypt_key} >> 16) & 0x7FFF), "sendPacket", 0) if $config{debugPacket_sent};
      }
   } else {
      use bytes;
      if ($self->{net}->getState() != Network::IN_GAME) {
         $enc_val1 = 0;
         $enc_val2 = 0;
         return;
      }

      my $messageID = unpack("v", $$r_message);
      if ($enc_val1 != 0 && $enc_val2 != 0) {
         # Prepare encryption
         $enc_val1 = ((0x000343FD * $enc_val1) + $enc_val2)& 0xFFFFFFFF;
         debug (sprintf("enc_val1 = %x", $enc_val1) . "\n", "sendPacket", 2);
         # Encrypt message ID
         $messageID = ($messageID ^ (($enc_val1 >> 16) & 0x7FFF)) & 0xFFFF;
         $$r_message = pack("v", $messageID) . substr($$r_message, 2);
      }
   }
}


*Network::Send::encryptMessageID = *load;
1;

here's your cryptkeys.
make a new txt file, and save it on the plugins folder too with name "xh.txt" without quote mark

Code: Select all

1169769913
1169769913
1169769913

and then, edit your Control/sys.txt
find "loadPlugins" and change the value into 1.
so it will looks like this "loadPlugins 1" without quote.

Thank you sir for your help. I would like to ask some more

Currently, im still stuck at "Timeout on Account Server... Reconnect in 30s" and repeating.

This is my current server.txt

Code: Select all

[VnRO]
ip 103.9.159.142
port 7900
master_version 214
version 53
serverType kRO_RagexeRE_2014_10_22b  (I tried 2013 08 too)
serverEncoding Western
recvpackets recvpackets.txt  (your recvpackets in the previous post)
charBlockSize 112
addTableFolders kRO\RagexeRE_2014_10_22b;idRO

(small note: I have tried several types of addTableFolders but nothing changes)

I had this information from WPE tool , explained in this picture
http://prntscr.com/ejby49

However, when i used GRF tool to extract clientinfo.xml from the grf. I got this

http://prntscr.com/ejbyox

which gave different master_version and version.

I tried both of them but still stuck at

Code: Select all

Connecting to 103.9.159.142:7900... Connected then Timeout on Account Server....

After already implementing changes as you mentioned in the earlier post. [/b]

I have to emphasize that no matter what number I put in master_version and version, the error is the same.
http://prntscr.com/ejcdpz

Please let me know where did I go wrong. Thank you kindly sir !.
Would you kindly explain about the steps in the previous post also sir? I copied your steps but not totally sure what they are for. Thank you again.

U're looking the wrong packet.
search for 64 00 ID. Your ID is 30B8 ! Are u sure master_login packet is 30B8 ?

http://openkore.com/index.php/Connectivity_Guide

0064 is the ID for ALL CLIENTS! It only can be changed by the shield !

Your exe are unpacked by themida. Easy to unpack thanks to ScyllaHide !
I'll be testing in your server !

Dear Sir ! Thank you for your kind help. I'd love to hear more from you once you have tested the server.

I am not quite familiar with the unpacking process. Would you kindly elaborate more on this matter?

Thank you again, dearly !
