sendto problem

[Phoemphun Oothongsap <poothon@xxxxxxxxxxxxxxx>]

Hi

I am using Red Hat 6.2. I have a problem with using "sendto" command.
I try to send a udp packet to different three machines. The packets are
sent back to back. The first packet can get through but the second
packet gets the Connection refused, the third packet is ok. I get the
alternated
result between connection refused and successful packet.

This is a code snippet :


:
:
while(1)  {

   for(i=1;i<=3;i++) {
       ret =  sendto(sock,(char *)&packet,
                      length,0,
                      (struct sockaddr*)&neighborAddr[i],
                      addrlen);
   }
:
:
}
:
:

Do anybody have an idea how to fix this problem?
