[Guild Wars] Packet encryption

[Akai]

Yes. I'm deciding to do it a little bit of a different way. Give an error after the character is created and required re-login to click Play to play. Sorry about the late reply, I had a rather averse reaction to drops at the eye doctor and have felt horrible most of the day. ><

Please do not spam the armor set input with tests. >_> It's been tested already and works.

Removing the scene for now would probably be the best idea. Later after the emulator is finished, you can always go back and add scenes in to make the emulator better.

For the scene crash, did you try and program it out of the emulator and client? Because the client is still probably trying to read the scene. Just a thought.

What I'm doing is forcing the error 7 to prevent the client from freezing and allowing the player to quickly login again.

Thanks Theora, finally got GW proph/factions installed last night. Going to get Nightfall tonight.

Need anything else for ID's or anything?

 

[Theora]

Any news?

The framework for instance handling has been implemented and I'm now processing the packets required to load in. About one-hundred packets need to be figured out. Oh yes, this will probably go open source at the first release.

Nothing that I can think of for now. But thanks for the help.

Okay, good luck. Feel free to ask for help if you need it.

Bleh. I was demoralized by one packet. It made no sense why sending it resulted in an error 7. After much contemplation I checked that the game server was indeed establishing an encrypted connection to the client. I found it was not. This was due to an authorization flag not being set that was set only when connected for character creation. ><

Anyway, as for current progress...

Please note: All those other characters are not actually there.

Detailed Progress:

• Instance framework in place and working
• Game server identifies character creation clients from the instance clients
• Support for shared instances
• Support for separate instances
• Instances are deleted when no player(s) exist in them and are created when that particular instance is requested.
• Character creation bug fixed(due to adding instance framework)
• Login server supports all options except "Edit Account" and "Enter Store" at the character selection screen.
• Supports the first two steps properly for loading into an instance. The third is accomplished for now by packet replay.
• Major bug fix in the armors.ini loading code.
• Instances have a max limit which will be configurable. If that is reached, instead of loading into the shared instance a new instance will instead be created.
• Many bug fixes which resulted from the addition of the instance framework.
• Login server appears to be stable. I can't crash the darn thing.
• Game server may or may not be stable.
• As of 12:09PM today the health bar and energy bar appear and the game client does not crash when trying to open the Skills, Inventory, or Character windows.

In addition,

The latest version of the packet dump program is compatible with the latest Guild Wars build(#21,350) which can be found:

In an unrelated addition to the addition, I"s is a great manga.

Wow,very big progress!

 

[Akai]

Great progress Theora. Seems you are moving right along with this project.

 

[IStrongI]

Wow, i saw the name and sorta laughed a bit at first, but seems like theres actually people who know what they are doing working on this project. Good work guys, and looking forward to an official release.


NC = Teh Sux! =P

nice this project almost finished huh

Uh, barely. Maybe you should think about how hard this is before you start posting things like that.

awesome, i just found this thread and it's just... awesome. Keep up the good work =)

[sTo0z]

Amazing!

I am no expert programmer such as yourself, but I am just curious how you're going to implement/work-around that entire streaming data idea GW was founded on.

Where is the map data going to come from on your emulated server? Are you streaming the map to yourself or does your client previously hold all the map data?

How does the server handle NPC conversations, item lists, NPC locations, etc? Is it all in the client or part of the streamed map data?

If a server admin was going to make a change, isn't the technology founded on the fact ArenaNet can stream little updates to the map files?

Is that part of your emulation direction or have you gone after something else?

Sorry to ask so many questions.. just curious, in an amazed sort of way.

Keep it up man, you're already a hero around here.

 

[scottgl]

I have approximately 15 years of both low and high level C/C++ experience, so perhaps I could help with development of your server. I am familiar with various encryption algorithms, so let me know if you would like assistance. By the way I went to #gwlp on irc.rizon.net and you were not on.

I disassembled your packet dump program, it looks very interesting. I started writing my own which uses FindWindowA, ReadProcessMemory, etc.

1. The map data for the client is stored in the client's gw.dat already. If needed a server side version of the map coordinates will be created manually.

2. It appears that NPC's are streamed at the loading screen for an instance. This is speculation but the packets for each NPC seem to follow...

@Ayalp which seems to be player actor. I still have not figured out if these can be sent at anytime in an instance, considering the blasted clients keeps crashing when I delete one player from the list. It's also interesting to note that only players that belong to a guild generate so much information.

Item lists are handled when the client requests the information from the server. I don't know about talking to NPC's yet though. I'd assume that some form of ID's are exchanged between the client and the server with the quest text being stored client side.

3. ANet can do that. This won't be able to. I don't know their file format nor how the content streaming system works. This server already assumes all content is on the client side. For now...>

I have approximately 15 years of both low and high level C/C++ experience, so perhaps I could help with development of your server. I am familiar with various encryption algorithms, so let me know if you would like assistance. By the way I went to #gwlp on irc.rizon.net and you were not on.

I've been in the channel from the time I posted it. You must have had the wrong server or channel. =/ But I'm definitely interested in assistance. Contact me in the channel.
