This system connects to login server at port 2618. How it is possible to edit system to connect to another port than 2106(default)?

I found same examples of extenders in forum that they use functions writen in C++ and not using opcodes like this guide to extend/fix some functionality. My question is how do you define in your C++ code classes or structures that L2server uses? For example i saw functions using User *pUser pointer for input. Did you read the assembly from IDA and create from the begging the whole class/structure?

:D 1000 thx!!!

does anyone has C4 Function list with the offset of each function?

Thanks a lot !!! Problem Solved :D

mcbigmac i am not expect anything i just made this question because my results are not the same as thoose described by the author of this topic.

Could you please be more spesific about the IDC script? how it will map sub_"hexaddr" functions to real named functions?

after analyzing the leaked C4 PTS L2server.exe with latest IDA(6) for x64 i get no string names equal to function calls like thoose you describe but i can only find strings like Loading Multisell, Loading Henna etc. Most of functions named sub_******.  And the ida's debugger for x64 processes like this one don't work, it asks for something like "dbgsrv.exe". Am i doing something wrong?

wow why all of these validator tests? i think it doesnt matter...

Just look the result!

Well they didn't do it for the lulz, did they.

 

 

Most servers with a more comprehensive security system are using sold system.

And therefor are more susceptible to getting screwed.

You'll rarely find a server with a developer who has their own homebrew).

 

I'd say the largest part (atleast l2off), are just the smaller changes and small shared gimmicks here and there.

Thank you for help until now...i have one more question.

How is it posible to edit client's algorithms? Where did they find the source code? The client files are in binary(exe,dll etc) mode.

They use IDA Pro Database or something similar?

The source is in your help topic :p

I'll think about including full source, but there doesn't seem to be much interest in extenders on this forum, most people just want the finished product to plug-and-play, there aren't many like you who are actually interested in learning for themselves.

I agree with you but few of us, like me, want to learn how did you create this extender from begin to end.

Is it possible to explain us step by step what you did with the full source code and how bypass works and linked with the extender?

Ty in advance :)

they made all this changes for better security?

why big servers cant connect with the common patched interlude system with l2.ini edited for their ip?

the only way to connect is to download their system from their website

what differences they have?

thank you!

good idea! Thanks!

i will check it

thanks

how this can be done? any idea?

i know servers that they give you items throw their web site...so they are sending queries to their databse but they dont need to restart their server each time. when you login with your character you can see the items in your invetory.

Ok when i make some changes to the database like changing username (to offline player) or adding items (to offline player) if i want to see them in game i have to restart l2server and cached.

Is there any way to see the changes without restarting the server each time?

Thank you.

thank you very match!!!! :D

how is it possible to configure this items??? which file i have to edit?

thanks.
