Hi, I have an inetd service on freebsd that calls a program
(daemon.py) with which I want the remote user to communicate. I can
call daemon.py from the command line on the host machine and it works
fine.
What I don't understand is how to make my remote client script
actually communicate. If I'm understanding correctly, the code below
just takes a message and sends it to inetd and writes the stdout from
the process to the client.
How can I modify the code to send a response back? Here's the
outline of what I want to do:
(1) client sends the message to the server (client -> inetd ->
daemon.py),
(2) client receives output back from the server,
(3) client user responds to a question from the remote process
(4) client continues to receive output back.
where 2-3-4 happen as needed by the remote process. Cries out for a
while loop doesn't it? I just don't know what to put in it. Currently
I just have steps 1 and 2 working. Client sends one message and gets
all output back. If server asks a question, processes deadlock with
server waiting and client unable to respond.
thanks,

def client(ip,port,message):
sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
sock.connect((ip,port))
sock.send(message)
for line in line_buffer(sock):
print line
sock.close()
if __name__ == '__main__':
message = ' '.join(sys.argv[1:]) )
print 'working... %s %s' % (SERVER_IP,SERVER_PORT)
client(SERVER_IP,SERVER_PORT,message)
print 'done.'
