I managed to get the RM PC to pick up its DHCP address from the Edubuntu
7.10 vm, when running Ubuntu from the hard disk - I just need to work out
how Andy created his PXE boot CDROM (which Phil took with him). Is there
an ISO image I can grab? Once I've achieved that and know that my
environment works, I can build an 8.04 server.
I'll extract the iso off the CD and email it (or a link to it). Emailed
it - it's 400k. Perhaps an IDE flash module instead of the HDD would be
the way to go for a permanent solution without CD or USB stick booting.
Having done a bit more reading the X-server graphics problem seems
fairly common. When 7.10 came out the default colour depth had increased
to 32 and there are multiple postings of previously functional setups dying.
It isn't helped by the changes to where / how one adds an ltsp.conf file
with the revised default setting, but I've got that narrowed down now
and will have a crack at it when I've got this paying work stuff out of
the way !
It's highly likely it will be better in 8.x and I'll try that over the
weekend too.
The other host was Mr Anthony Jarvis Site Manager / IT Technician
(I cheated and looked up http://www.middletonprimary.co.uk/staff/ ),
thanks to both for an interesting insight into the constrained world of
school IT with limited budgets and imposed solutions from Central and
Local Government !
When offering advice to the school we might need to restrain our
enthusiasm for spending other peoples money - is a managed switch with a
£200 premium actually *necessary* in an environment where recycled PCs
are being considered at £30 a throw ?
Personally I'm still inclined towards a server per classroom (or per two
classrooms) as that fits into the client/server ratio and wouldn't
overstress 100M ethernet.
For user authentication there's an LDAP article in LXF105 p98.
The school's 2M internet connection (leased line ?) could perhaps be
supplemented by the xDSL services available - Easynet is on the Westwood
exchange they do ADSL and SDSL. The BT estimate on the school phone
number is 5Mbits/s downstream but ADSL2+ from Easynet/UKOnline or
Be(coming soon) would add a bit more to that plus a faster upstream option.
