I'm trying to replace a 10BaseT DLink hub with a 100 Base TX DSS 5+
switch. DHCP doesn't work anymore.
The server is on one end connected via an FA311 netgear card. From
there, a 100' Cat5e cable runs to the switch in the attic. Then I
go to Cat5 STP cable for an additional 90' outside, underground,
and back above ground into the next building. The diskless machine
that boots via floppy is on the far end. A 190' run made up of a
100' and a 90' run seems to be within the range limitations for
100BaseTX. Then again, the cable is shallowly buried and could
be getting weathered.
I see DHCPDISCOVER and DHCPOFFER, but nothing past that.

goose dhcpd: DHCPDISCOVER from 00:02:e3:02:46:37 via eth2

The other diskless machine on another nic off of the same server, dodo,
boots just fine by the way. Is something obviously wrong in my dhcp
config file or am I looking at a problem with the switch? DHCP worked
when I was using a 10BaseT hub which makes me wonder if the line can't
support 100baseTX.
