Zitat von Kiss Gábor <[email protected]>:
The "3g" bit of the hostnames piques my interest as well -- could they be
cell phones? Cellular modems? Maybe they have a faulty NTP client? (But I
thought GSM had its own way of syncing time?)
I guess zillions of (mobile) users got address of your NTP server
from the provider badly configured DHCP server.
Try to traceroute some clients to see what is their IP provider.

This might be a problem. To my knowledge the DHCP option 42 (time
server) send an IPv4 address to the clients for use as time source. If
some moron used br.pool.ntp.org in the DHCP config this might lead to
one DNS lookup at startup of the DHCP server and subsequent reusage of
this IP address, no?
So your IP address will be the target until the DHCP server(s) are
restarted...
