er, I wondered about that. /var/log/messages mentioned the
DHCPDISCOVER, but
not what my DHCPd replied with. /var/lib/dhcp/dhcpd.leases indicates
NO leases
were issued. The win98 client seemed to be re-using an old address.
What DID happen, was the DHCPd on the NT box spoke up immediately and said
"DHCPINFORM from n.n.n.n not via eth0: not authoritative for subnet
192.168.0.0"
Linux' DHCPd then gave a little spiel about adding an 'authoritative'
directive.
(all this in /var/log/messages)

yup. All booting clients on their network did that. 8-/ Not good.

Riiteeo. I'll try the combination, and report back.
Does anyone know what the vendor-class-ID is for Linux' DHCPClient (the
one that
runs *after* the kernel has loaded. (screen says "running dhclient" -
that bit.)
Thanks Jim, Others.
