The problem with using hton and ntoh macros is that this is unnecessary
overhead for an embedded micro if it doesn't happen to fir the standard
network endian model. The solution I guess is to define our own macros that
allow use to specify what the network order is for your client/server
(either BIG_ENDIAN or LITTLE_ENDIAN).
Then a little endian embedded micro could talk to a big endian host most
efficently by using little endian on the wire.
Conversely, a big endian embedded micro could talk to a little endian host
most efficiently by using big endian on the wire.

Andrew Hannam.

I have it working now. The problem was that iptables was rejecting an
atempted connection to port 6600 on the server machine. Once I shutdown
iptables, the conneciton worked. Anyone have a quick iptables rule
that allows connections to port 6600?
Now the next problem. I've cross-compiled a Fluid application and
run it on my embedded ColdFire Linux box, and if barfs with a message
stating that the server byte order(i686) is different from the client
byte order.
How hard do you think it would be to add in network order data(using
the hton and ntoh macros)?
I'm willing to do the heavy lifting if someone points out all the
gotchas...
