fd=20 is the IPv4 wildcard interface and should not be receiving any packets. The real broadcast client is fd=25 and it appears not to be receiving the packets. Assuming that 45.3.255.2 is the broadcast server then it should be received on fd=25. Your trace (above) does not show the IP addresses so it makes it useless. This has nothing to do with auth being disabled, it just doesn't get that far. This shows the broadcast client being set up: > Broadcast enabled on socket 25 for address 45.3.255.127 > bind(25) AF_INET, addr 45.3.255.127%0#123, flags 0x39 > flags for fd 25: 0x1082 > addto_syslog: io_setbclient: Opened broadcast client on interface #3 > bge0 > setting SO_REUSEADDR on l...@127.0.0.1 to off > setting SO_REUSEADDR on b...@45.3.255.68 to off > io_setbclient: Opened broadcast clients and this is what should be receiving the broadcast packets. You shut off the log too early to see if it was seeing the broadcast packets to 45.3.255.127. You should also send us your ntp.conf. I don't know what's wrong here on the basis of what you sent. Try using -D4 when you run this and let it run longer. Danny _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
