Assigning a Fixed IP Address Based on dhcp-client-identifier

[Scott Coleman]

I finally got it to work.

The solution was to remove the "option dhcp-client-identifier" lines
from the host records and replace them with equivalent "uid"
statements (the byte lists after the uid keyword are the hex
equivalents of the ASCII strings "pos_30", "pos_31", etc. with a
prepended 0x00 byte which some clients, including mine, insist on
including for some reason).

I'm attaching the complete dhcpd.conf file for the archives. Thanks to
everyone who responded for their help!
