Fred - firewalls ? Let me think - as this happens many times that I forget to open the adequate port.

The code is there http://borkware.com/corebook/second-edition-source-code - 2 pages for the client -, but I find these lines :
   [...]

    serverAddress.sin_port = htons (PORT_NUMBER);
   [...]
    result = socket (AF_INET, SOCK_STREAM, 0);

I was looking for the adequate port - PORT_NUMBER is defined as 2342 : I am doing this immediately.

Thanks a lot !

Francis

Bonjour à tous et à toutes,


I am talking about Chapter 13 in the old "Core Mac OS X and Unix Programming" book from Marc Dalrymple and Aaron Hillegass OR their new chapter 11 of "Advanced Mac OS X Programming".

If I launch the simpleserver and, then, simpleclient from two different machines of my local network, then :
- the server remains "silent" ( doesn't do any "accepted connection from 192.168.1.10:51035" )
- the EOF character (^D) can't be sent from the client properly ( no "EOF" on client side, but ^D in the terminal )
- the server waits for nothing to come
- at last the client shows "could not connect.  error: 60 / Operation timed out".

How could you help me - by the time I re-read and understand the code for any eventual limitations ?

Firewalls ? Although without seeing the code it's not obvious what code level things could be wrong.

Fred
