Re: [K12OSN] *DHCP Questions*



Couple of questions for you....

Not ever having used Windows ADS....does ADS depend in any way on Windows
DHCP?  If not, then it might be best for you to use the K12LTSP DHCP.  Is
the K12LTSP server on the same subnet as all the Windows machines? 
OR....does it have two NICs and the terminals sit on their own network.  

Now....we'll assume that the K12LTSP server shares the same network as
everything else.  If that's the case and ADS doesn't need Windows
DHCP....then simply turn off the DHCP on the Windows side and use the
K12LTSP DHCP.  You'll need to make sure the K12LTSP server is handing out
the correct addresses and subnet for your network.  This is most easily
done during installation .  It's possible to change on the fly, but may
not be worth the headache.  If the users home directories live on the ADS
server and not the K12LTSP server....you can simply blow away the K12LTSP
server (back up a few configs like icewm if you use it)...and then
re-install...this time entering the correct info along the way.  It is
possible to change mid-stream....perhaps someone on the list can point you
to all the files that need to change...or maybe Eric's K12LTSP-initialize
script will do it....haven't looked.  

Assuming you'll need to add static entries for things like servers and
printers....this is easy to do....just look in dhcpd.conf for
examples....or you can use Webmin to add them graphically.  Once you add
all the static (reserved) entries...make a backup of it so you can use it
another time....I cut and paste from mine year to year....I've been using
Linux DHCP servers for years.
