Hello everybody.

I've got a small question about RAW sockets and pinging.

I need to consequently ping N machines.
My OS is QNX 4.25.

The problem is that I receive their replies (ICMP echos) twice with a
short delay.
I've used packet scaner and it showed only one reply.
Where does the second comes from?

What could be the problem?

MSG_PEEK isn't set.

Thank you.
