Hello, I have written a simple Daytime sever using network-alt[1] (I am sorry if this is off topic, is it ?) The server is: server port = do runStreamServer (nullStreamServer {handlerSS = sendDaytime, servSS = port}) sendDaytime = handlerWithHandle $ \hs sa -> do putStrLn (show sa) hSetBuffering hs LineBuffering time <- Time.getClockTime hPutStrLn hs (show time) hClose hs It works, but I have the following problems: When I run server "10013" from ghci, the prompt returns immediately and if I do a query to that port I don't get anything, until I go and press enter on ghci and the daytime is sent to the client. Like if the prompt was blocking all IO or something like that. The other problem is that I tried to make a program, so I made DaytimeServer.hs: main = do server "10013" I compile it and run it. It returns immediately and the server of course, is not running. I think what I am missing is that server, after running runStreamServer should block and be able to reply to all the queries (in the final version I'll also have runDgramServer as well) and be able to receive a signal, upon which it should close the socket and finish. How can do that ? Any help will be appreciated. Thank you. -- Pupeno <pupeno@pupeno.com> (http://pupeno.com) [1] http://www.cs.helsinki.fi/u/ekarttun/network-alt/ I am currently using the select mode.
