How to close socket connection on Ctrl-C in a python programme
You need to register a hook for this, something like:
#!/usr/bin/env python
import signal
import sys
def signal_handler(signal, frame):
# close the socket here
sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)
As per the docs the error OSError: [Errno 48] Address already in use
occurs because
the previous execution of your script has left the socket in a TIME_WAIT state, and can’t be immediately reused. This can be resolved by using the socket.SO_REUSEADDR
flag.
For eg:
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.bind((HOST, PORT))
