Server Discussion Aegis Wrapper - Server Wrapper

Hey unleashurgeek, I've thrown together a quick script to deal with crashes and server restarts. Check for it here, feel free to look it over and see if it helps with your project here.

 

Nice we need something like this for sure

 

So much of this is just straight up false.. please try and avoid lying to people who know no better.

Firstly, where did you pull 50ms from? Your ass? There is no way that proxying the connections server side in the local network would create that level of overhead, that level of overhead would not even be created if I was for example to proxy connections from a server in LA to a server in Dallas, and back again.

Secondly, though he is not directly hooking into Starbound his solution is working, and his method is by no means not kosher, it is simply a less friendly way of achieving the same result - and it contains almost no disadvantages in the short term (until they release packet information and/or API)

Your mention of how his system to ban will create overhead is also bogus, all traffic is filtered through his proxy, thus his proxy can deny/accept individual requests from individual clients without it effecting any of the other requests - only at EXTREMELY high loads (hundreds of thousands of connections) would this be an issue.

I'm not trying to knock your ability as a programmer, but you are quite clearly not that experienced in the server side of things, at least IMO. The statements you made are sweeping blanket statements with no technical grounds to stand on - and you have no right to knock his methods publicly without those grounds.

Just my 2 cents.

 

I can't wait! I guess Starbound Plugins will be the next big thing!

 

Just a small progress update here. Been messing with packets as much as I can today. If anyone can try their luck mapping out the chat packet that would be awesome. So far I have enough information to have commands respond and tell me information, like /players actually tells me the number of players in game! The problem is with the limited knowledge of the chat packet I can only do little things with it until I can write a method for creating my own. So again, if anyone can figure out something about the Chat packets that would be awesome! Here is what I have mapped out so far:

Code:

byte:
0: always 5
1: 5 + #ofCharacters + 2? <- I think this is completely wrong
2: Color?
3: ???
4: ???
5: ???
6: ???
7: Connection number
8: length of sender name (assuming 6 for ease of explanation)
9-14: Sender name (Server)
15: Size of message (assuming 17 for ease of explanation)
16-32: Message
33:+ I have no idea

 

Ill test what I can do. I do packet analysis for work.

 

So my problem is i know networking but not the data field for this game, but here you go a striped packet (Removed the header)

Code:

The chat message was "fgdgsssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss"


I doubt the devs are going to give you access to the details right now would cause to many security issues.

 

Has anyone figured out how to create the handshake response? I've been pissing around with the linux client in IDA without much luck so far

Highlights so far include:

http://imgkk.com/i/6mc6.png
http://imgkk.com/i/zfcg.png
http://imgkk.com/i/1m8i.png

 

I tried doing that awhile ago, the handshake is clearly passed through some sort of encryption client side. From what I do know I am pretty confident that it isn't zlib decryption on the packet data.

 

Some more stuff:

http://imgkk.com/i/du8c.png
http://imgkk.com/i/88jl.png

I'm not really good enough at reverse engineering to fully understand this, but it looks like some sort of shifting/masking similar to basic xor encryption?

 

Just a thought but if you made a "man in the middle" approach, that forwarded the handshake etc.. Wouldn't that suffice for now? I know you want to be able to send it yourself, but it should work, at least from what I recall from the cube world man in the middle server. I'm no pro, but just a thought.

 

Maybe that is exactly what I am doing

 

I doubt there could honestly be many more security issues than what already exists..lol /butnotreallylol

 

Any eta on this?

 

This is what I do to make my chat packets that work so far :>

Code:

[byte] PacketID = 5
[byte] playLoadSize = (nickLen + msgLen + 6[unknown] + 1[for the msgLen] +1[for the msgLen ])*2
[byte x 6] always seems to be [1,0,0,0,0,1]
[byte] nickLen
[byte x nickLen] nick
[byte] msgLen
[byte x msgLen] msg

Hope that's of some help.
It would be nice if all these packets where know as alot of odd stuff seems to happen in some of them sometimes.

 

The funny thing is a patch is coming soon... you might have waited to long to release.

 

You sir have been beat. This one freaking rocks!

My apologies towards the community about Starrybound, they truly seemed like a good solution. However on a positive note I would like to say that I am still heavily developing this wrapper and after the countless rewrites I do believe it should be done soon.

On release, or a couple days before if I get everything pretty, I will release the full source on github (however at this moment the code is on a private repo).

Furthermore, The biggest and most important feature that this wrapper will be releasing with is a plugin API similar to Bukkits, thus allowing developers to create tools based on a unified system and for server owners to make the experience for users both seamless, clean, and complete. Also I have my best web devs on the case of getting a site for plugin distribution / forum ready for this wrapper.

 

I'm very excited for this and as are a lot of other people I'm sure! Do you have any idea on an ETA for the wrapper?
Thanks again for all your hard work.

I hate to give ETAs; however, I would say ~week. What I might do is release a bug filled version with a couple tutorials on how to write plugins before release so when actual release happens there will be plugins!

If people want to start thinking about plugins now, the plugin structure is extreme similar to bukkit, so I would suggest looking at bukkit plugin tutorials. Also I will be releasing with a couple open source plugins to kick start it and to give examples as structures.
