The rule what I know 1. set data in uip_buf 2. calc uip_len 3. nic_send() Is this incorrect way? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fabio Giovagnini Sent: Tuesday, February 06, 2007 3:22 AM To: uip-users@sics.se Subject: Re: [uip-users] ping test Can you see your packet with wireshark? If yes, are all the packets (ETH, IP, ICMP) correct? Where does your test fail?
