I wanna connect linux server and windows client
These are simple(basic) example of linux server and windows client

These code work well in (linux server, linux client) and (windows server, window client)

(becuase, is it local ??)

How can I connect linux server and windows client??

(Case of linux, I executed codes in VirtualBox)

If client enter with port 55000, IP 127.0.0.1, they interaction, and change
some messages
