FOSS gamedev and creative worlds

can i create a server or something, to play/test things with two players?
Also a not official server?
I can start a server over minetest gui, but i can only join with one player.

Yes, you need a LAN and two computers, one as the server the other as the client.

ok so it isn't possible at one computer?

Sorry, I assumed you wanted to play together - it is possible to use just one computer, each player has their own login - the one that enters the world first is automatically the Admin (with all privs)

Ok so can someone say me what i have to do, that that will work?
What should i read at first?
How can i login with a second player?

I run a server over the server tab, and then??

Ok, so you create the "new" world; if you're using mods you "configure" the world, then "start game" for the Admin player - do what you want then "esc" to "exit to main menu". Second player enters a new "name/password" and "start game" to play.

I tryed this but an error occurs:
"Failed to bind socked (port already in use?)"

You are trying to create second server on the same machine.

Please, explain in more detail what you are trying to achieve.

Do you just want to play to players on one pc on the same world? Then go to the server tab, start a server, and you have the first player. Then open a new window, go to "client" and enter "127.0.0.1" ass adress and enter a new username. When you join you should see the first player on the map.

thx jbb that was exactly what i want.
sorry if i don't have spoken so clear.
