Create a TCP listener under OS X�

[Saphir]

I develop a TCP server based on OS X (to implement ModBus protocol). I have 2 problems:
(1) unable to create listener for por number < to 1024 !!!
(2) when I create a listener on port 2000 for exemple, TCP Cient on PC is unable to connect my TCP server running on Mac OS X !!!

I have stopped the embed firewall of OS X without positive result.

Thanks for anybody help me.

(1) This is correct. On unix-based systems, ports <1024 are reserved for things such as ftp.

(2) Try running the LabVIEW shipping examples on TCP/IP communication on a port > 1024. Do these work?

thanks for the answer,
(1) Ok...
(2)I've just ran "Multiple connections - Server.vi" and "Multiple connections - Client 1.vi" examples.

Results for port 6341 :
(a) Server&Client on OS X --> OK
(b) Server on Win98 & Client on OS X --> OK
(c) Server on OS X & Client on Win98 --> error 63 from Client

Results for port < 1024 :
(d) Server&Client on OS X --> error 42 from server
(e) Server on Win98 & Client on OS X --> OK
(f) Server on OS X & Client on Win98 --> error 42 from Server

Results (a),(b),(d),(e) and (f) are expected but I don't understand (c) !?
