Source Code for Current C# Implementation

[own3mall]

I'll try testing it a bit. Could you look at my source code changes though and offer some feedback?

I think you should use BeginReceiveFrom

Here's a good example of async udp server:

For now, I don't see any additional benefit from using BeginReceiveFrom rather than BeginReceive. I'll leave it for now and will test it on my Windows machine with a server using the cvar you provided to see if it works.

What does the client currently receive from the master server when the server browser is used? Doesn't it just receive a list of IPs and Ports... then client goes and queries them for ping and server information? If this is the case, I already have logic in my PHP based version to return servers in an array that have sent an acknowledgement of being alive within the past 10 minutes. I'm just not sure how I should send the data... one server:ip port combo at a time or the entire array within a message sent by the socket?

With the PHP version, the Online field in the database will most likely not be used... simply, we check the time before last acknowledgement. I think the PHP one has the potential to work just as well as the C# version. I'll post source after I've tested it as well to see if it works. This of course takes time.

Well, from what I understood, BeginReceiveFrom is the proper asynchronous method for UDP socket.

Even in C, you use recvfrom for UDP and recv for TCP.

I didn't reversed the custom protocol MoHAA uses yet. It may take me a day or two (first I have to have time ) but this can be done quite fast.

Yes, you are correct. However, the C# code is not using a typical socket construct. I'm using the UdpClient class (appears to create sockets and remove some of the craziness). It uses the BeginReceive method for async UDP packets. I'm going to see if this class works with my current code. If it does not, then I will go back to officially using a socket and using the BeginReceiveFrom call. The code for this would be easy too... I'm spending a lot of time searching everything and looking for examples. That's the way I understand it after doing more research. Either approach *should* work. Documentation on this stuff is pretty piss poor.

RR, if you have the source code I sent a while ago, I already reversed it. Well, not reversed it, I just modified it in memoru. I believe MOHAA 1.11 uses protocol 8 and I made it 9 when testing version 1.12.

The credentials in the source code for the database do not work. At least, I was unable to even query a server at that IP address. Has the information changed? I want to use my script to dump all the tables into a file so I can test locally.

I fixed up my version quite a bit. It's in the DropBox folder MoHAABox\OwN-3m-All\MoHAAMasterserver.

If "config.txt" is located within the service installation directory (directory from where it runs), it will read the file for mysql database credentials. If it's not located (so when xnull / razo is testing, make sure you delete this file) , it will use x-null's database information by default (hardcoded). This helps with testing.

I ran it on my XP x86 SP3 slow Atom machine, and every 5 minutes or so, the database entry would update properly. I fixed the way my socket was working because my original code was not correct and was crashing hard. I also fixed a log problem in my version. I think this version is ready for testing. It's using Async UDP and should be threaded. I restarted my computer, and the service started and was running just fine. It was updating the database like it was supposed to. Please take a look and test it?

Also, have we found out anything more about how the information should be sent back to the client from the master server? Right now, the master server is just listening for servers. It's not returning the list to the client's ingame browser.

Hey what is the status? Do we want a C# version or PHP/Python version? Where are we going to host it?
