That sounds like your router/firewall is trying to track all the NTP clients and exceeding the maximum number of connections. Is connection tracking disabled for the NTP port? With iptables it can be configured like this: iptables -t raw -I PREROUTING -p udp -m udp --dport 123 -j CT --notrack iptables -t raw -I OUTPUT -p udp -m udp --sport 123 -j CT --notrack -- Miroslav Lichvar _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
