[K12OSN] Adding users on multiple ltsp servers

This set up is not concrete. However the bandwidth between the
locations is ISDN and I can't change that for some time. The ltsp
servers are going into an already functioning network and the complete
roll out is based on the initial 60 days after I install the first two
servers. This gives me a good amount of time to work out the kinks and
make adjustments. I set up the origional network 3 years ago with
RedHat 6.2 and it works like a charm. However back then all of the
workstations on the network were dumb terminals with one or two Windows
PC's here and there. Over time they have replaced the dumb terminals
with PC's and don't have a clue on keeping them selves up to date. When
we suggested LTSP they thought about it quite hard, Then they got hit
with a virus and spent a week trying to fix something and then had to
throw money at the problem. This put them over the edge and they wanted
to give this a try. I have considered many options with this setup,
but in the end I have some specific things that I want to keep the
I can't switch to higher bandwidth connections as it is not available
for all locations and where it is available the telco requires they
maintain the network (for a monthly fee). Oh and they only support MS
I want the end user to be able to create accounts on the existing
machine and make the duplication on the ltsp servers transparent. The
main reason being that I don't want the end users tweaking/breaking the
ltsp server. I can script or config by hand the initial setup and rsync
the files there after.
We have already decided to restrict files that are synced between
machines and in the name of "The Corporate Network" users will be very
restricted on what products they have access to.
To this end the five servers are almost identical, except they reside
on different subnets for bandwidth control. This means that several of
the ltsp config files need to be changed to deal with the subnet scheme
I have configured. By the way thanks for the pointers on changing
/etc/dhcpd.conf to accommodate specifying alternate ltsp vs dhcp
So I think I am somewhat limited on the options. I have opted to use my
existing dhcp server (10.0.0.1) and a single NIC in each LTSP box. I
have five subnets (10.0..0) and plan on adding the lstp box as
10.0.x.9 at each site. I am hoping that I can get squid to still work
with this setup. Thankfully the network is for non technical adult
users so they are not likely to work out how to get around that.
So that's where things sit right now. It could change, but not much as
I have to get this working in two days.
