Ok, with all that - I am basically out of ideas. Can you check that
local.bro does not contain anything that might prevent dhcp.log from being
written (the line would have DHCP::LOG in it). But that is very unlikely.
If that yields nothing - could you perhaps capture a tiny snippet of the
dhcp traffic with tcpdump, just run bro on the command line and see if
that generates dhcp.log? If no - could you potentially (privately) send me
a small amount of that traffic?
