Well i don't want to be nit picking however, i believe you're mistaken
here. You can reuse port on which you are listening for outgoing
connections too.
You need to use* setsockopt(... SO_REUSEPORT ).*..
here goes the demo:
#!/usr/bin/python3
import socket
import threading
READER1_ADDR = ("127.0.0.1", 23008)
READER2_ADDR = ("127.0.0.1", 23009)
class wait_conn(threading.Thread):
def __init__(self, addr, name):
super(wait_conn,self).__init__()
self.name = name
self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0)
self.sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
self.sock.bind(addr)
self.sock.listen(3)
def run(self):
s, a = self.sock.accept()
print(self.name, ": Incomming connection from: ", s.getpeername())
s.close()
self.sock.close()
t1 = wait_conn(READER1_ADDR, "r1")
t1.start()
t2 = wait_conn(READER2_ADDR, "r2")
t2.start()
w1 = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0)
w1.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
w1.bind(READER1_ADDR)
w1.connect(READER2_ADDR)
w1.close()
t1.join(1.0)
t2.join(1.0)

Obviously the difference is that kamailio does bind()
and listen() on the
socket (ip:port) first -- maybe that should have said to be clear about
what case we talk here. So try with socket(), bind(), listen() and then
connect().
Once there is listen() on a socket, read events for it mean accept()
should be done. The kernel won't create an outgoing connection from a
listen socket, but use ephemeral ports.
