I'm trying to implement an NNTP module in Haskell, but it seems the Network.Socket module doesn't convert the native byte order to network byte order, so the connection gets denied.  When I reverse the bytes in the address by hand and try to connect, it locks up.  What's wrong?

There was a discussion on it:

One answer (use Network.Socket.inet_addr) works, but isn't very
satisfactory. Another recommendation pulls the htons(), et al.
functions into Haskell using FFI. This is better, but more initial

But I believe both answers aren't correct. The binary serialization
module should replace 99% of the need of htonl(), etc. For socket
addresses, the Network library needs to do the endianness conversion,
like the PortNum type does.
