Dhclient settings aside, I'm afraid I don't understand the original issue.
Would you care to elaborate why is the server expecting some non-default
behavior? What is the error message on the server side?
AFAIK, usually the client broadcasts a dhcp request packet to the LAN, and the
dhcp server catches this packet (which already has a MAC address of the source
inside), sets up a lease for this MAC and answers back with an IP and other
data. Why do you need to explicitly send a dhcp-client-identifier?
Are you trying to get a lease for some other value of MAC, not the one that
eth card uses to actually send the request? (You are not trying to hack into
someone's MAC-filtered network or something, right? :-) )
Or is there something else going on?
If you are trying to achieve some highly non-default setup, it would be a good
idea to tell us as much as possible about what is customized and why.
HTH, :-)
