Damned Noob ! ! !
Yes, I know, some people are probably saying that, I apologise profusely, but this is the only way to learn. Read lots and ask questions :-)
Now I have the server working, I have a question that may sound kind of weird.
Can I run TWO servers at the same time. Namely, I want to run the one I have working now, AND, my daughter wants to run one from her laptop. It has a different IP Adress within the LAN, but would be bringing the connections in on the same WAN IP. Would using different ports send the connections to the right worlds? (Those with port XXXX come to mine, those with port YYY go to hers. Or am I barking up the wrong tree?
Here's hoping others can help.
Cheers
Never mind folks, a little research and trial and error, and viole! two servers. One from Minecraft, the other CraftBukkit. Yeah Baby!
