[K12OSN] dhcpd and tftp

["Terrell Prudé, Jr."]

There were a few "managed hubs" made in the past, but today everything's 
pretty much switches.  The only reason a hub or switch would need an IP 
address is if it allows you to telnet into it and make configuration 
changes (duplex, port speed, etc.).  The cheapie $40 NetGear or LinkSys 
switches do not have IP addresses.

As for the IP addressing scheme:  192.168.0.0/24 is the default for 
K12LTSP.  Have you done any special tweaks from the default on this 
server, including but not limited to, say, /etc/dhcpd.conf?
