If your willing to pay I have the following specs available:
8 GB DDR3-1600
Intel Xeon 1230V2
50/25 Upload & Download
And I forgot to mention:
300 MB/s Read and 150 MB/s Write SSD.
I have Windows xp with Microsoft Office and I have got 256 mb of ram. Is this good enough for minecraft server? I don't know how to port forward so you'll have go do that yourself.
In your minefactory Reloaded config make sure it says something like this:
# Whether or not to generate rubber trees during map generation
B:WorldGen.RubberTree=true
I'm guessing not. Okay make a new folder. Copy over these files:
Config
Coremods
Mods
Launch.bat (Sh if your on mac/linux)
Server.properties
Tekkit.jar
Minecraft_server.jar
And your World save
Then launch the server
Try hitting the gearbox in the top right hand corner. Check Increase PermGen Size and increase Ram.
Since Technic Launcher is a Jar on Linux you might be able to use the above parameters. I would recommend option 1 though
Usually deleting the Technic folder would fix an error where it's stuck. I'll try and give you a fresh technic folder with Hexxit installed later today.
Try deleting deleting the Hexxit folder alone.
