Sockets

[Rafael Mentz Aquino]

Hi, there,

I'm trying to create a socket script to work as server,
using the example from the lib reference manual,
with a little change that puts the script in looping,
so I can make more than one requisition without stopping
and starting the script all the time.

When I execute the script, it works fine, listening in the
given port and answering the requisitions...

But If I try to put the script in background (in FreeBSD)
I got an error saying (address already in use). I guess
its because of the while 1 looping...

The script is below.

Thanks!!!

know.. ;-)
