Project: Independant MSL / Server Lister
Posted: 21 Mar 2009, 03:46
by ~Sanguine{DXA}Rose~
As I originally posted in DXA Forums:
Greetings my children,
In approximately 2 weeks or less time this project shall be completed and posted.
Project Info:
I am going to code an independant MSL from DX, it should be approximately 100kb-150kb executable
depending on the platform. Versions of the code will run on: Linux, BSD, Windows, and MAC OS/X.
There will also be a DX server query program as well that will connect to a MSL and download the server
data. This will be able to run on: Linux, BSD, Windows, and MAC OS/X.
This code will be released in Full along with a library version of the code for which you can include in
your own code or a possible windows/linux library version of it. I rarely do any coding if any in windows
so it may be a while for a windows dll to be available for use.
This program will be a fully featured CLI (Command Line Interface) program. It will be fast and portable
to every known operating system able to run code. This includes the MSL and the Server Lister. The
code can be modified to be used by Rune, Unreal, Unreal Tournament, etc. basically anything that uses
Unreal 1 Game Engine.

Inspiration for this project:
http://www.dxalpha.com/forum/viewtopic. ... 63&start=0
To urine off HDD21.
There is another post I believe in R T K were he mentions he wrote the MSL in C code and
cried about never releasing it to us assholes. This is why the code of choice for this project
will be in C with added support that will make it portable to every known OS/Platform.
That is all my children,
~Sanguine~
I have figured out the handshake so its going to be really soon that this will be
released or a beta version of it as a prof of concept. This should be allot more stable
then using Unreal to run a MSL. The protocol is not that complex or really that mysterious.
The Handshake responses are a variation of ARC4 Encryption using a private key
created by the name of the game used.
Edit:
The MSL has been sourceforged:

After re-reading this topic 3 times I think I understand it.
You're basically remaking Deus Ex Server List?
(Only version I have, there are later versions).

It's goal is a MSL not that. The functionality of dxsl will be included in it
but it is not close to it. Instead of relying on Unreal MSL code I am making one
independent of that code that will be a native linux server which would be
more stable.

Uhm... what is a MSL? Do you mean a independent Master Server utility?
If you mean that, there is already one around: UMSE (Unreal MasterServer Emulator) by DejaVu. Its yet unreleased, because of possible insecurity, but I could modify it for more security.

Finally someone who knows what I'm doing!
The Major difference is that I'm releasing the full code instead of hiding it. I am also
pretty sure its going be coded better then that as well. Chances are it the same possible
insecurity as what I have foreseen while codding it so far.
As it stands I'm scrapping the Basic Auth from it and going to try to get a working beta
version before I mess anymore with the Handshake. It will take some time before I am
even able to figure out how it works precisely. I know the encryption routines because
I've seen the source code for them. I'm not sure exactly how they are implemented.
Basically this means its Authenticates anyone even with invalid handshake response
to get a server listing. I'll work on this later after I release the initial version.

That doesn't make sense.

The protocol allows it LOL. Master server sends the Authentication string, MSL says
what ever and sends them the list when they send the response. Hence Authentication
with invalid handshake responses.
MSL Says: AZIGCV
DX Response: RCa/Ynig
The point being im ignoring the DX response and just validating it.
I think this explains it?

Ohh, so you were referring to YOUR master server program!
I thought you meant the real master server.
