Hello,
 
I have written a program with netgraph which allow me to connect a node soket to a node Ethernet. But my problem is that the program exit after calling NgSendMsg, in fact it stop at this step:
        
               if (NgSendMsg(csock, ".",
                      NGM_GENERIC_COOKIE, NGM_CONNECT,
                      &ngc, sizeof(ngc)) < 0)
                errx(EX_OSERR, "can't connect to node");

 
I don't know why it can't connect these nodes. I have verified the content of the ngc variable and it is what we need.
 
I have been blocked for 2 days and I need help.
 
Thank you a lot,
Samiha, ayed_samiha at yahoo.fr
