The only way to disarm people in Minecraft is to join a Multiplayer server with the Bukkit plugin "mcMMO" enabled. That way you can increase your unarmed level to enable you to disarm other players when you hit them using your bare fist.
You will need to port forward.
you give them the IP address of your server and then they tipe it in on the online option on the mane menu of minecraft and then they should be able to join
Its impossible I've tried
You can open a LAN server if they are within your household, or you can join a server.
It depends how the server is set up. The owner of the server can change the size of the server to let more or less people join.
It is a public server that you can join.
The ip to join a server.
I don't think this is the right place to promote your server but it might get some people to join. Also, it depends, for some, whether it is a tekkit server or a bukkit server or just a server, so for all who want to know, which is it?
Simply click "Multiplayer" then do "direct connect" or "add server" and type in a server IP. From there, you can play with friends and family on a Minecraft server.
First off, an online server means that the server is up and running. It is available for people to join. An offline server means that the server is down and closed for people who want to join.
Unless your server has a whitelist or a blacklist, anyone with the IP address of your server can join it
