Re: [K12OSN] LTSP server with 3 NICs?



Ah, I think I see the issue. There was a piece of info I left out. Because you now have more than one DHCP scope, you've got to be careful with your global options (those not in a "shared-network XXXXXX" section). Basically, you've got to move all those "option" statements for 192.168.0.0 into the "shared-network WORKSTATIONS" section, and the "option" statements for 192.168.4.0 into the "shared-network WORKSTATIONS-2" section. The reason is that all the global statements for 192.168.4.0 just over-rode all your statements for 192.168.0.0, so your 192.168.0.0 thin clients would've had problems, too. Sorry 'bout that.

Here's the tweaked version.  Give this a read and see how it goes.

Also, what types of clients are you using--EtherBoot or PXE-boot?

Hello,

I followed your steps but something seems to be wrong.

I activated the 3rd NIC, made the changes to hosts and the
/etc/dhcpd-k12ltsp.conf  (/etc/dhcpd.conf is blank in my k12ltsp FC6
setup)

I rebooted the server, then turned on one of the clients.  The client
screen is hanging on:

"Loading 192.168.4.254:/lts/vmlinuz.ltsp"

tail -f /var/log/messages/ shows:
