I'm using the ntp package in debian squeeze and the ntpd process is listening on hundreds of rfc1918 addresses that are not configured on the server.Check this out:Mar 26 10:07:24 server ntpd[14701]: ntpd 4.2.6p2@1.2194-o Sun Oct 17 13:45:13 UTC 2010 (1)  Mar 26 10:07:24 server ntpd[14702]: proto: precision = 0.986 usec  Mar 26 10:07:24 server ntpd[14702]: Listen and drop on 0 v4wildcard 0.0.0.0 UDP 123  Mar 26 10:07:24 server ntpd[14702]: Listen and drop on 1 v6wildcard :: UDP 123  Mar 26 10:07:24 server ntpd[14702]: Listen normally on 2 lo 127.0.0.1 UDP 123  Mar 26 10:07:24 server ntpd[14702]: Listen normally on 3 eth0 66.xxx.xxx.xxx UDP 123  Mar 26 10:07:24 server ntpd[14702]: Listen normally on 4 eth0 192.168.1.1 UDP 123  Mar 26 10:07:24 server ntpd[14702]: Listen normally on 5 eth0 192.168.1.2 UDP 123  Mar 26 10:07:24 server ntpd[14702]: Listen normally on 6 eth0 192.168.1.3 UDP 123  Mar 26 10:07:24 server ntpd[14702]: Listen normally on 7 eth0 192.168.1.4 UDP 123  Mar 26 10:07:24 server ntpd[14702]: Listen normally on 8 eth0 192.168.1.5 UDP 123  ...  ...  ...

Why is ntpd listening on most of 192.168.1.X/192.168.2.X
debian;openvpn;ntp
I don't have the full output pre-grep because my scrollbuffer filled up, but:# ip addr show dev eth0 |grep 192.168.[12]inet 192.168.1.1/16 scope global eth0inet 192.168.1.2/16 scope global secondary eth0inet 192.168.1.3/16 scope global secondary eth0inet 192.168.1.4/16 scope global secondary eth0inet 192.168.1.5/16 scope global secondary eth0...And this solved it:ip addr del 192.168.1.1/16 dev eth0It was most likely a side-effect of some fiddling I was doing with openvpn configurations a while back.
