Then consider what I do, which is run a single-NIC K12LTSP server, like
this:
REALLY BIG WAN
|
|
Router
(Cisco 3600)
|
|
-------------------------------------------- MAIN LAN
| | | | (say, 10.40.0.0/20)
K12LTSP K12LTSP Win2K DHCP
Client Server Client Server
(10.40.0.254)
In this scenario, we make sure that dhcpd does *NOT* start when the
system comes up. That means doing chkconfig on dhcpd, like so:
chkconfig --level 2345 dhcpd off
If for some reason that doesn´t work for you, then we do it manually.
Go into these directories:
/etc/rc.d/rc2.d
/etc/rc.d/rc3.d
/etc/rc.d/rc4.d
/etc/rc.d/rc5.d
and rename Sxxdhcpd to Kxxdhcpd, where ¨xx¨ is some number. On my
system, it´s S65dhcpd, for example. I renamed it to K65dhcpd in _all
four_ of these directories. Double check that it´s done in all four.
Really.
My K12LTSP server, you will note, is running in a single-NIC
configuration on a switched (Catalyst 3500) network, and the K12LTSP
server has Gig-E fiber. A Bay/Nortel 350T or 450T switch w/ the Gig-E
interface will work equally well. Since I happen to run the
infrastructure, I´m therefore the administrator for DHCP too, so I can
add the LTSP stuff to the scope myself. If you´re not so fortunate,
then just ask your DHCP admin to add that stuff to the existing DHCP
server´s scope. Yes, it does work, and no, you won´t have any DHCP
issues. The Windows boxes will simply ignore the TFTP and NFS stuff
when the OS boots. With one tweak, this is exactly how I run it, my
tweak being that the Cisco 3600 is itself the DHCP server (yep, they can
do that).
