How to know the ip and the available ports on my workspace?


I would like to install the manager " Ajenti " but I do not know what the ip to access it , and not know how to see the available ports.
Ps: I am beginner with linux, and managed to install manager " ajenti " but I can not access it.
Ps2: if possible , answer in Portuguese because I know the basics of the English language.


Does this help?


Thanks, I managed to solve the problem in part , but it’s a start .
The problem is that when accessing the door , I am infinitely redirected to the same “project link”

Edit : the door is open , but is being blocked. I would like to know the reason for the block. the door in question is the 8000.
