Hi all, I'm trying to do some standard socket stuff using the Network.Socket library. This example is a UDP server: import Network.Socket proto_udp :: ProtocolNumber proto_udp = 17 port = 10162 main = do s <- socket AF_INET Datagram 17 bindSocket s (SockAddrInet (PortNum port) iNADDR_ANY) putStrLn $ "Listening on port " ++ (show port) ++ "... " (msg, n, addr) <- recvFrom s 1024 putStrLn $ "Received " ++ (show n) ++ " bytes from " ++ (show addr) ++ ": " putStrLn (show msg) Using the equivalent C program (socket, bind, recvfrom) I'm able to successfully receive a 64 byte message from my test program. The Haskell version, however, does not return from recvFrom. I've also tried wrapping this in a withSocketsDo, with no effect. How can I proceed to debug/troubleshoot this program? Thanks, - Scott Bell
