MapleStory Private Server on Linux

[Morhsn]

I'm aware I'm not the first one to bring this up nor am I the last.

I've recently started getting into the Linux world (recently being last nine months, so not that recently).

I love Linux and think there are many winning concepts in its design.

Obviously Java is meant to be multi-platform which isn't a secret, so why is the default choice for private servers Windows?

What would be the difference of running it on a Linux machine (CentOs for example)? What would it require?

Thank you for your help.

Just to be clear:
I'm not referring to playing the game on a Linux machine, but rather running a game server...

Well, based on my personal experience with Linux vs Windows, I have noticed a VERY noticeable ping and response time between both of them.

I have noticed that on Linux, there are less 'random' slowdowns and a much faster response time.

Yea, I know...
Plus, there's the added value of not having to restart almost never... Stability for the long run, and not daily reboots like in windows...

But the question is, how easy would it be to actually implement it?

It's very easy and the source most people use already supports linux. The only reason why people don't use linux is because they are unfamiliar with it, or suck at running bash commands via command line. I can't really think of any disadvantages of linux besides that.

It doesn't take long to convert the batch files to shell scripts and it's much easier to use ssh (putty, etc) to restart/run the server on linux, odinms rev 988 works fine without any modifications.

Thank you for clearing that up.

I agree.

You said odinms rev 988 works fine without any modifications, would other revs require modifications?

Thanks for the DOS batch file to shell guide, I will read it, but other than that - are there any other modifications I should take into consideration?

Thanks.

 

[JewSanta]

.sh files are included and tuts are in the java section for how to set it up.

I remember getting some errors with my modified source because some of the things I had made were written badly and I had to rewrite them, you might face similar things and some errors with filenames since in *nix they seem to be case sensitive.

Not sure how many of the current repacks/whatever work without modifications.
Haven't really used any of them.

Okay, and what about the JCE files, I never really understood why those were required, but would they also be in Linux?

 

[FateJiki]

I did remember running Shootsource-based repacks on Linux with no runtime issues at all. It's a bit hard to implement it on Linux if you have never done it before, but after that, it's a breeze.

Yes you need them in linux.

Back when I ran MapleGenesis in 08', Sparks help me setup on a Linux dedi, it was great, ran a ton smoother than when it was on windows. It made a noticeable difference.

They're used for AES Cryptography, which is what MapleStory encrypts their packets with. The default java installer for windows never had it, and neither does the linux one.

 

[Morhsn]

Okay, thanks everyone, this is really helping!

Can someone explain what does "-Djava..." mean in the .sh script?
It's telling me it doesn't know any such command!

Thanks.

You will have to edit that but that's how mine is.

You should of course set the java classpath in .bashrc
JAVA_HOME=/root/jdk1.6.0_xx
PATH=$PATH:/root/jdk1.6.0_xx/bin

change the /root/jdk1.6.0_xx/ to the path where your java is located at

Okay, thanks,
And what should I put instead of passwd? DB password?

 

[greenelfx]

Linux servers are also much cheaper than Windows servers!

This isn't necessarily true and shouldn't be a reason why you would buy a server over another. You should buy linux only if you are familiar with linux.

No, just include these files in the folder.

I decided to try arberms2 tutorial as seen

as a starting point and from there to know enough to use it on any source.

But when I run launch_world.sh I get:

Exception in thread "main" java.lang.NoClassDefFoundError: net.sf.odinms.net.world.WorldServer
at gnu.java.lang.MainThread.run(libgcj.so.10)
Caused by: java.lang.ClassNotFoundException: net.sf.odinms.net.world.WorldServer not found in gnu.gcj.runtime.SystemClassLoader{urls=[file:./,file:dist/arberms.jar,file:dist/mina-core.jar,file:dist/slf4j-api.jar,file:dist/slf4j-jdk14.jar,file:dist/mysql-connector-java-bin.jar], parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}

I have a feeling like it has something to do with compiling a jar or something which I didn't do, but I don't know how it can be fixed.

All help with how to solve this will be very appreciated.

Thanks.
