[K12OSN] Troubleshooting new install

[Larry Mateo]

Dan: I had a similar problem recently: the clients would get an ip
address, the OS download would begin, then the clients would hang at
random times during the download.  It turned out that one of the switch
uplinks between the clients and K12LTSP server was over 100 meters (328
feet) long.  I had to, unfortunately, force that link to 10/F to get it
to work.  It only affects five of that site's thirty clients, so it's
not much of a problem.

Also, check all Ethernet connections between the server and clients to
ensure you don't have a duplex mismatch.  That will also cause funny
communications problems.

Also, check patch cable integrity by swapping them, and, if you have the
expertise, plug in the ol' sniffer and watch the packet-level traffic
for clues.

Good luck.

I'm testing a fresh K12ltsp 5.0 server (updated 2x with Yum Update). 
I'm
using the non-standard 1067 port for DHCP so I don't conflict with a
Windows DHCP server on our network.  I used ROM-OMATIC to create the
non-standard disk images on floppy.  It appears that the clients are
getting IP addresses from the server, but they are not completing the
operating system download.

Any suggestions would be appreciated.  Debugging info below.
