binding to localhost - slightly OT

[Ajay]

hi!

I am making the following call on my PDA which has WLAN connectivitythis prints 127.0.0.1
the PDA has an assigned IP address.
so if i go
UDPserversocket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
UDPserversocket.bind((socket.gethostname(), LOCAL_SERVER_PORT))

this binds to the localhost instead of the assigned IP address. how can i
get it to bind to the assigned IP? i dont want to explicitly enter the IP
address into the bind call, since the IP may change.

thanks

cheers

If you .bind to a specific address, you are only going to be reachable
from that address -- is that what you're trying to do? If so, then any
of the addresses for your host should be just as good (or just as bad).

I suspect that what you're TRYING to do is bind(socket.INADDR_ANY, ...
so that OTHER machines can send you datagrams... I believe a '' would
also work as the first argument to bind, instead of INADDR_ANY.
