Tekkit 1.0.6 Server: How do you add mods?

[TechTurbine]

Hey, I am trying to set up a custom Tekkit server, however I can't seem to add a single extra mod on the server without it crashing. I've scoured the forums, but I couldn't find anyone with a similar problem to mine. Also, I realize that this isn't exactly the right board to post on, but for some reason, I can't post on the Bug report board.

Here is my error report:

I think that your are getting this error because you are using the wrong version of Forge (7.8.0.712) for the Minecraft (1.5.1) version you are using.

You are using a build for Minecraft version 1.5.2, Forge build 7.7.2.682 is the last one for Minecraft version 1.5.1.

[TechTurbine]

Well, whats weird is that the server works when i dont add in any new mods. And when I look into the Tekkit.jar, it says I have the proper forge version (V.7.7.2.679). I've gone into the public chat and they say that since change to Tekkit platform, I have to make my own custom modpack and server for it to work, and I have no idea how to do that :P

[thebird]

That is odd, your log says that you are running Forge build 7.8.0.712. What mods are you trying to install?

[TechTurbine]

I... fixed it. I decided to just screw it and make my own custom pack with Tekkit. Thanks for your help anyways :P
