I dont understand what this has to do with file descriptor.. whatever that is anyway. That means the clntsock variable isn't an open, available socket. Note that you close the socket right after sending the response - are you sure you don't have an indentation error there? -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list

It should be outside the loop. Shift it left so that it lines up with the while. What happens now is that the socket is closed after the first recv(). Then the next round in the loop fails because the myclntsock is closed. -- Piet van Oostrum p...@cs.uu.nl URL: http://pietvanoostrum.com [PGP 8DAE142BE17999C4] Private email: p...@vanoostrum.org -- http://mail.python.org/mailman/listinfo/python-list
