I am not an expert on sockets, but I have both a Linux installation and a PPC
Mac OS X 10.4 with both ghc-6.4.1 and ghc-6.6. So if you allow me some
additional details (such as complete program texts), perhaps I can perform
some useful experiments under your conductance.
I can reproduce it with the following:
module Main
where
import Control.Exception
import Network.Socket
import System.IO
allocSocket :: IO Socket
allocSocket =
do { s <- socket AF_INET Datagram 0
; handle (\e -> sClose s >> throwIO e) $
do { connect s (SockAddrInet 6802 0x7f000001)
; return s
}
}
main :: IO ()
main = withSocketsDo $ do { s <- allocSocket
; getChar
; sClose s
}
If you run the program on OSX, you can check the bound address while
it's waiting for a keystroke. Type "netstat -an -f inet | grep 6802"
to see. I get:
udp4 0 0 127.0.0.1.61704 127.0.0.1.6802
which is correct. When I run this program on Linux/i386, I get:
udp 0 0 (anonymized):33412 1.0.0.127:6802
ESTABLISHED
(I removed my IP address.) The second bound address, however, is
wrong: the octets are in the wrong order. Notice, though, that the
port number is correct!
Thanks for looking into this!
