The accept() methods waits for a new connection and gives you the information For the moment if I open the client before the server, it fails because client doesn't find server connection and stops running. On the server, the script will just need to bind to a socket and listen to that connection, This actually works fine for me, though I had to adjust the port in client. In this video we will see the Basics of Socket Server with Multiple Clients with Example. I am writing a program for a camera network. accept() but in UDP socket you just bind server and anyone connect (if i am wrong correct me) so how to control the The 'socket reset' happens because the client sent an ICMP port-unreachable in response to the datagram sent to a socket that wasn't there any more.
