For those out there that have had as much trouble
installing K12LTSP as i'v had over the past week -
getting the error. "Error transferring install image
to hard drive - probably out of disk
space" when installing. A simple "linux allowcddma" at
boot prompt solved this. Also I found that when it
asked for disk 2 and 3 I was better off inserting the
disk - waiting for about ten seconds and then hitting
the OK button. Otherwise the machine would just hang.
Thanx Les.

Les,
you make perfect sense when you make distinction between feasible
and advisable. It is possible that i suffer form the "frustrated teacher
syndrome" and give answers that go beyond the direct scope of the
questions, but this one just seemed to cry for help.
by the way, pdf is just as bad if not worth than ps, so is rtf.
the reason: most printing people do deals with text, so the pretty page
description stuff is just hindrance, and yes, i've been doing a lot of
post-processing of print jobs - it is easier for me, since i have lots of
control over format. julius

Paul Nelson, or anyone that is involved at Riverdale,
I read that the Riverdale HS lab went online September of 2002. (That
particular school has a great writeup on k12ltsp.org on
how/when/why/etc) I'm curious how the hardware has been faring now that
almost 2 school years have gone by...
I guess I ask, because I'm not sure how to properly figure TCO with a
k12ltsp lab... Theoretically, the thin clients will last forever. I
have circa 1993 machines running just fine as thin clients, so the
"forever" at least has a decade of age to back it.
How has the school transitioned through the versions of K12LTSP? I
don't remember what version was out in Sept 2002, but I'm sure it was no
newer than version 2. Are you running version 4.0.1 on the same
hardware? How does it compare performance-wise?
Have you noticed less "maintenance" required for thin clients than
regular computers? (no hard drives to fail, although that's not
terribly common even in a "regular" lab)
Do you have any comparative energy savings from using the thin clients
and flat screens? I know they use less energy, but also you probably
don't need to air-condition the labs either... I know that figure isn't
specific to just you, and I could probably figure out the costs that it
would save me -- but I'm trying to fill in any questions when I use you
as a big example case. :)
Thanks a million,
-Shawn

Thanks for the info. Is there anyway for me to get more involved in the
k12 documentation? Not sure if you all need anymore help. But I'd be
more than willing to help out if you all wanted/needed it. (NOTE:m I
changed the subject since we're no longer talking about CD-ROM's, the
original discussion is included below)

CDroms in the terminals is a fact. Let's use it. And we could even try to autdetect every device whn it's added, then we supermount it. What do you think K12LTSP developers ?

Dear Folks,
I need to set up a VPN between 2 sites connected to the Internet.
I need something that is easy to install and configure and that is robust
enough to do windoze networking - need to mount a remote directory on a
pc. If you have any experience, ideas, please share. thanks julius

Well, i suppose you could use a PC and IPCop or Smoothwall with two
NIC's, but a much smaller footprint and lower power consumption option
might be wiser, just make sure you buy two of the same type VPN-endpoint
routers for each end to ensure interoperability.
I use the 2XW, but there's other decent one's out there:

Redhat/fedora/k12ltsp has CIPE built in so you can configure it
with the redhat-configure-network GUI. It runs over UDP and
doesn't object to going through NAT on the way. It probably
isn't the most secure choice but unless you are a bank it
should be good enough. If you aren't starting with a machine
with CIPE included, I'd look at openvpn first.

A fairly simple way to implement a cdrom server can be found in the
archives at Linuxjournal (It is based on the cdserver howto at
tldp.org).
http://www.linuxjournal.com/article.php?sid=5639
CDROMs are copied into a directory as iso files and mounted using the -o
loop. The article also explains how to set up the volumes using
automount. A second directory is needed to allow browsing to work with
automount.
I followed the procedure fairly closely and it works well for us,
including the automount.
We use it to run Windows programs in our Sunday School lab which use
WindowsXP computers. They access the LTSP server via ethernet. Thin
client terminals can access them as well, but the windows software is a
problem (Wine works on some, but not all).

Les,
I can actually use light-weight k12 server for remote end and a
spare k12 server for hq end - cipe is obviously included. my problem with
cipe is the documentation. it is rather verbose in obvious places and very
sparse in non-obvious. The description of server end seems to translate
into "and the magic happens here". the docs for openvpn are a bit scary.
perhaps i just need to plug away at cipe. thanks, julius
