help :giaddr

[Glenn Satchell]

I'd try commenting out every unnecessary line and simplify the config
as much as possible. If that works then add lines in one at a time
until it fails.

In particular, what are you trying to achieve with statements like:

> if exists agent.remote-id {
> option agent.remote-id = option agent.remote-id ;
> }

which assigns the value of the option to itself?

My pick is that one of the log fields is set to a null string, so I'd
comment them out for now. eg leased-address may not have a value when
processing a DHCPDISCOVER packet.

And this
  if exists agent.circuit-id
should be
  if exists option agent.circuit-id

unless you want to refer to a variable named agent.circuit-id which
doesn't get assigned anywhere else in the conf file.

Also as Simon said in an earlier post - 3.0.2 is about 4 years old,
there have been 7 or 8 releases since then. Latest is 3.0.7 in the same
stream, or 3.1.1, or 4.1.0alpha-something. 3.0.7 and 3.1.1 are highly
recommended for an upgrade. 4.x if you are keen to test new features or
ipv6.
