The thing is that you seem to have problems also in italian man, you are confuse, it's not about languages.
I think you are new, you should try to use schemes which are already created and tested by other players, like the one mentioned by Monkeyisland. You can find these schemes here:
https://www.tus-wa.com/schemes/ Regarding your last two questions:
1- that is called "Rope knocking". It's set up as OFF as default, you need to activate it if you play offline. But if you try the same scheme online, you will see that it works perfectly.
2- you need to type in your own host this command: /ts and press enter. It's a function that works only online.
PS: At least try to use google translate instead of forcing everyone else to use it to understand you!
Damn italians! The worst illiterates on the earth! Without hands language it's a mess! Upload a video of your hands to ask questions! xD
