<guillaume.comte10@gmail.com> declaimed the following in
gmane.comp.python.general:

> Unfortunatly, my_socket.bind((src_addr, 1)) doesn't work. I get the error message: "socket.error: [Errno 49] Can't assign requested address"...

	Port #1 is in the range of OS privileged ports; you may need root
privileges to bind to it.

http://www.w3.org/Daemon/User/Installation/PrivilegedPorts.html

{Note: one link I hit indicates that M$ Windows does not have this
restriction; and 

>>> s = socket.socket(socket.AF_INET)
>>> s.bind(("", 1))
>>> 

seems to confirm that... OTOH: specifying an invalid IP address
regardless of port produces

>>> s.bind(("192.168.1.10", 1))
Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
  File "<string>", line 1, in bind
error: (10049, "Can't assign requested address")
>>> 

whereas using the DHCP assigned address gave

>>> s.close()
>>> s = socket.socket(socket.AF_INET)
>>> s.bind(("192.168.2.101", 1))
>>> 
}
