I used socket library in python , and made two simple projects which are server.py and client.py , then I executed them to server.exe and client.exe When i run both (server.exe and client.exe) on my computer , it works fine , but when i run them on two separated computer , client can not connect to the server which run on another computer !! Here is my codes : Server side : #server codes import socket #make socket for server server = socket.socket(socket.AF_INET,socket.SOCK_STREAM) #use our ipv4 for making server on port 9000 , and show it on the screen ip = socket.gethostbyname(socket.gethostname()) server.bind((ip,9000)) server.listen(1) print(f"The server ipv4 , give it to client to connect to the server -> {ip}") #wait for client print("Waiting for client ...") client_socket = server.accept()[0] #send hello to client client_socket.send(b"hello") #close server and client client_socket.close() server.close() print("Done !!") Client side : #client codes import socket #get server computer ipv4 from client server_ip = input("Please enter server ipv4 here : ") #make client socket client = socket.socket(socket.AF_INET,socket.SOCK_STREAM) client.connect((server_ip,9000)) #receive data from server (b"hello" which sent from the server) Print(client.recv(5).decode('utf-8')) #close client client.close() print("Done !!") There is no more exception in these two codes but just one exception appear on client side when I am trying to connect client to the server which run on another computer as I said above The exception which appear on client side say that client socket attempted to connect to the server , but it could not make connection to the server !! and it said about timeout connection . I searched alot and watch lots of videos which make the same projects for testing socket in python and it works for them , but not for me I allowed client and server in firewall on two computers , also disabled firewall , but it did not work at all , and the same exception appeared. I used netstat -a (cmd command) on computer which server was running on it , and saw that the server socket was listening on port 9000. Nothing seems to work , any help will be appreciated (sorry for my English) Continue reading...
