[ntp:questions] sntp server rejected

I found the error:
flash=800 peer_loop

That's because tftpd32 shows refid equal to self ip address . That's the
situation called "peer loop".
This can be healed with recompilation of tftpd32 or with setting "tos
orphan 10" in client ntpd.

BTW ntpdate and ntpd first step are working. Thanks anyway.
