I just need a little help.

[Gee_Wisz]

I created my modpack and it works nice and pretty, but when I try and use those mods on my server, it crashes. How do I fix that? What do I need to download and do? Do I need to make a new .jar for the server to run off of?

First of all:

1. Some mods only work on client side and other mods on server side.

2. Some mods have differnet files for client and server.

3. You have to be sure that your mods config files are the same (client - server)

Alright, understandable enough. Now how do I create a server file (such as the TekkitLite.jar) that will cooperate with my modpack?

lets see mmm:

1. Recomend you use the server.jar from tekkit lite or MCPC+.

Tekkit Server: http://mirror.technicpack.net/Technic/servers/tekkitlite/Tekkit_Lite_Server_0.5.7.zip

MCPC+: http://ci.md-5.net/job/MCPC-Plus/

-> Just download them and copy the jar file and rename it to whatever you want.

Then create a script to launch it:

Windows: server.bat

java -Xms2048M -Xmx2048M -jar server.jar -o true

PAUSE

Linux: server.sh

java -Xms2048M -Xmx2048M -jar server.jar -o true --nojline nogui

It will generate all teh files that you need, then jsut copy the mods to the mods folder and core mods to coremods folder and config files to config files folder.

Then start the server one more time with the script.

Remeber that with MCPC+ you can use plugins in a native way and witht he nromal server.jar you cant.

[Gee_Wisz]

I use MCPC+ so that I can use plugins, indeed, but when I run the server I get an error that says

Is this caused by an outdated FML I downloaded or did I just dun goof?

[josephpaz07]

What mods are you trying to use?

[Gee_Wisz]

Everything from TekkitLite (0.5.7) with Mo'Creatures, Portal Guns and Gravity guns. I'm adding Optifine and the Zipline mod later, but they aren't in the pack yet. With Mo'Creatures I did add the GUI API to the coremods folder as the most recent build requests.

EDIT: Now it's just telling me that FML has identified a non-mod "NEI-RedPower Plugin" in the mods folder. Any idea what that's about? I'm 150% sure that NEI RedPower Plugin is a mod, considering I downloaded it alongside the other RedPower mods just to update them.

Of use the following fixed mods for MCPC+

[Gee_Wisz]

It's still just saying that NEI-Redpower Plugin isn't a mod, and when I tried removing that, it said the WR-CBE mods were a problem, then apparently weaponmod.... Eventually I'd just be stripping down every mod in the server at that rate. Any ideas as to the NEI-Redpower problem?

EDIT: I got it to work, it was whining at a duplicate of another mod that was present (though I don't know how it got there). Thanks for trying to help though, you did get me past the first error, I guess the NEI thing was a self inflicted problem. XD
