The origins of the questions trace back to Mr. Robot series, where I noticed that people join "group" or "parties" chat through Bash Shell to communicate with other people or group. Then I got interested and started to search online for it and found answers for it, but only for LAN chats, not globally. I guess you have to have a server running so people can connect to it and chat through that or something similar to that. Can anyone please help me figure out how it works and how I can replicate it?
Thank you in advance!
