Hi All,
(python 3.2 on windows)
I have a couple of questions regarding the below code:
1- In line (15), what are these variables tcpCliSock, addr supposed to hold
and do?
2- Why do I have to specify the buffer size and what does it mean?
3- When I try to run the below code and its corresponding client it works
ok for the first time, but then it gives me this error:
Traceback (most recent call last):
File "C:\Python32\Khalid Stuff\tsTserv3.py", line 12, in <module>
tcpSerSock.bind(ADDR)
socket.error: [Errno 10048] Only one usage of each socket address
(protocol/network address/port) is normally permitted
I thought it had to do with the address so I changed the port and it
worked ok. so,:
A/ isn't the optional tcpSerSock.close() supposed to close the connection
for later reuse?
B/ why is it when i go to the IDLE and enter tcpSerSock.close() and it
accepts it, it still gives the same error and doesn't close the connection
for reuse by my code?
Thanks a lot
1. from socket import *
2. from time import ctime
3.
4. HOST = ''
5. PORT = 21567
6. BUFSIZ = 1024
7. ADDR =(HOST, PORT)
8.
9. tcpSerSock = socket(AF_INET, SOCK_STREAM)
10. tcpSerSock.bind(ADDR)
11. tcpSerSock.listen(5)
12.
13. while True:
14. print('waiting for connection ...')
15. tcpCliSock, addr = tcpSerSock.accept()
16. print('...connected from: ', addr)
17.
18. while True:
19. data = tcpCliSock.recv(BUFSIZ)
20. if not data:
21. break
22. tcpCliSock.send(bytes('[{}] {}'.format(ctime(),data.decode(
'utf-8')),'utf-8'))
23.
24. tcpCliSock.close()
25. tcpSerSock.close()
