I have an NTP server on the network that is acting very weird.
I have not changed any of the ntpd.conf settings. Its a debian box and I did a regular install.
I have an NTP client on the network. If I run ntpq -p "192.168.1.5" I get "timed out, nothing received". However, If I look on wireshark, I can clearly see UDP communication between the two hosts, the client requesting, and the server responding. I can also ping between the host and server just fine.
I have no firewall rules, I did iptables -F on both machines.
I have no idea how to approach this problem. This is very bizarre.
Also, this worked yesterday fine and just started acting up today. I have rebooted both boxes, looked in /var/log/messages, and haven't seen anything unusual.
