Hercules WPE Free - June 14th Patch

 

Made Possible Thanks to Yommy

• We're only able to provide you with this feature thanks to Yommy, Thank you very much!

WPE Free - Official Packet Obfuscation Support

• Packet spamming is no longer possible by normal means, with this feature each packet sent has its own id, so spamming (by sending the same packet more than once) is impossible.
• For this feature to function you MUST NOT use the 'disable packet obfuscation' client diff.

  conf/battle/client.conf

  // Whether to enable the official packet obfuscation support (good vs WPE)// 0: disabled// 1: optional (not recommended) -- identifies whether it is required// 2: enabled (recommended)packet_obfuscation: <value>

• Currently functional for over 44 clients (Thanks to Shakto!): 20110817, 20110824, 20110831, 20110906, 20111005, 20111012, 20111021, 20111025, 20111102, 20111109, 20111122, 20111207, 20111214, 20111220, 20111228, 20120104, 20120111, 20120120, 20120202, 20120207, 20120214, 20120229, 20120307, 20120314, 20120321, 20120328, 20120404, 20120410, 20120418, 20120424, 20120509, 20120515, 20120525, 20120605, 20120612, 20120618, 20120702, 20120716, 20130320, 20130514, 20130522, 20130529, 20130605, 20130612, 20130618

• Currently functional for over 44 clients (Thanks to Shakto!): 2011-08-17 - 2015-05-13

Special Thanks to

• Yommy
• ..Yommy
• ...The all-awesome Yommy~! Thank you again!
• Shakto for the 44 PacketKeys!

Also - SQL DB Updates & DB2SQL

• For logical and performance reasons we've modified the structure of the renewal item db tables, atk and matk no longer share the same column, equip_level was replaced by equip_level_min so that we could add equip_level_max which is required by new renewal items. Note however that because of the previous atk:matk format, it was not possible to provide a upgrade file that would save the matk data
• Item script errors from sql dbs used to point to a inexistent line number, it was modified to display the item id instead.
• This update has shrunk the sizes of the item db .sql files, making it possible for tools such as phpmyadmin to parse them, once again.
• With this patch we're also introducing a new official plugin, db2sql, its purpose is to make it easier for our developers to keep the .sql db files up to date (but you may use that to convert your own if you so desire, too), to use this plugin (when it is enabled in plugins.conf) type server tools db2sql in the console.

you awesome ! ~

[Yommy 265]

for anyone who requires, the 3 keys are hardcoded to each client, you can search the keys in hex editor and modify for something unique.

for those with IDA / OllyDBG, the keys are pushed just before the PACKET_CZ_ENTER reference (not the actual string)

Just an update the structure is a bit different in the new clients. The 3 key pushes comes up a lot of instructions before

push PACKET_CZ_ENTER.

 

so just scroll up a bit once you find 

 

68 6C 30 89 00 (push offset aPacket_cz_ente)

nice!

[goddameit 52]

awesome

[Dastgir 1246]

. Amazing patch.

Great work Ind and Yommy.

[Takumirai 1]

This is sooo helpfulllll in all server owners..

[EriNa_KillerSoul 9]

Yes!niCe!

[Takumirai 1]

If WPE are now able to counter,

- im hoping and looking forward also for DDos Protection..

DDOS will not be covered by the hercules dev and staff. It's the duty of your hosting to provide ddos protection since it's a hardware related and this project is a software related.

[Shakto 45]

A thing is missing :

The possibility to configure our own packet key (3 key) in the conf file

[cJei 4]

Very nice!

[thanna 11]

this is very cool

[Jedzkie 58]

Even RPE blocks this update?

[Ind 945]

Yes, anything that may be used to send packets outside of the client will not function (if you send as much as 1 packet outside of the client the formula in the client and in the server will go off, and the server will disconnect you in the next packet).

[pajodex 0]

can be used on rA?

[Dastgir 1246]

can be used on rA?

You have to convert it to rA compatible and patch it.

any one who can convert this to rA? badly need it

[Yommy 265]

either request at rAthena to convert it, or change to using Hercules

 

Hercules devs will not create this for rAthena o_O

I'm using 07162012 ragexe and if I diff the client with "Disable Nagle Algorithm" I get disconnected at random times or whenever I try to disband my guild. So I would suggest that people uncheck that diff. This maybe an isolated case, but that's how it was for me. Tested with different diff combinations and removing that one along with skip packet obfuscation seems to fix the issue.

Does this occur on a clean version of Hercules?

I don't have src mods. I only have custom npcs and edits to the import files. I even did a fresh checkout of packets.h to make sure I have the latest version from the main branch. For now, I would say that the anti-WPE feature is a little overprotective. Sometimes, clicking an npc - move - click npc again results in disconnection. Of course this will require further testing because it's too early to confirm or disprove my findings. And I love this emulator for rolling out updates that makes so much sense. So, salut!

awesome perfect
