Is there something special about bond0 or is it just another NIC? What
are you expecting to do when you use -L?

Please upgrade to 4.2.4 first. However can you check that you are
actually binding to the interface? It should say that it's listening on
the address you are looking for. NTPD should listen on every interface
on port 123 so I'd be surprised if it weren't there.
If necessary, build ntpd with debug mode and then add -D 2 -l stdout to
the command line and it should spit out more information to stdout when
you run it directly.
