Thank for your answer. > Can you see the packet coming-in through tcpdump ( tcpdump -n -i eth0 > udp). There are no coming-in packets yet, theres nobody sending packets. Shouldn't recvfrom() block until something arrives at the socket? > U can try my programs Thank you. I read them, but I am doing my first steps in net programming and my code is too simple. It just opens a socket(AF_INET,DGRAM,0) then it bind() to the local address, then it connect() to the destination address. I know this last step is not necessary, but according to Unix Network Programmming by R Stevens there should be no problem in doing so. Then it tries to recvfrom() and I start getting thos messages.
