Public bug reported:
The clock of one of my routers running Dapper had bogus time (something
that ntpd was slowly but steadily working on). Then I added an
interface and boom! the time was stepped. OSPF went into an retarded
state, loosing random routes and everything was going crazy.
After the ordeal was over I found the /etc/network/if-up.d/ntpdate
script, where time is stepped _every_ time interfaces go up/down. This
is probably okay on a laptop or something, but it's madness to do so on
a server. I sure know OSPF isn't the only service that gets really
confused when the clock leaps.
There's actually a reason why the manual page of ntpdate says the
following about the -b option: «This option should be used when called
from a startup file at boot time.»
I've now deinstalled ntpdate (it served no purpose anyway since I have
ntpd), but really, this package should not be part of the default server
installation with this behaviour.
