Apologies for missing this: you cannot use a hostname there: you need
the dotted-quad IP address.

Pretty much what it says: you are trying to send more stuff than will
fit. The client can indicate an ability to accept packets larger than
the small default, so this might be client-related. (ISTR that windows
offers larger packets, I doubt that udhcpc does.)

Are you still sending option 19 too? Is that expected?
