We have a server with a private IP which has mail sent to it through our
county firewall. We have a public IP address which is used to do NAT
AFAIAA. Through this and an arrangement with them we have 2 servers
that are accessible through the firewall from outside. We access them
via webmail.romsey.hants.sch.uk and www.romsey.hants.sch.uk addresses.
This means that staff and pupils can log on to our email server (and I
can FTP to alter the web) from home or school and we have an internal
email service that still works even if the broadband connection goes
down.
I am about to trial a service that will allows pupils and staff to get a
listing of their NT domain folders fpr upload and download through the
server. this is using a Linux server running Navaho. Works very
quickly because they have a single binary for it all. Not cheap though.
The web server is a Cobalt Qube running the SunOS Sausilto(?) which is
stable but cannot cope with too many requests. I'd like to get a SUSE
box up and running to replace it as a web server only using MySQL and
PHP to handle our online KS3 ICT course, so i could use logging in and
record pupils use of the pages. One day eh?....
Off the point but could be of interest ...
Actually our County LEA (Hampshire) are scoping a project to produce a
complete learning system to try and incorporate everything from SIMS (or
similar) integration and online courses, class setting management and
learning system management. They have someone looking into lots of the
standards to help with this including AFAICR XML, SOAP, eGIF (??) etc..
I remember it was said that a browser interface was going to be
definite, which makes me think they are after using open standards.
Can't remember the guys name but I think he was the author of PenDown?
for the RISC OS platform. I think their intention is to put together a
specification andthen put it out to tender. It may involve working with
other authorities and could well lead to something quite big?
The reason I mention this is because there was discussion here of a
possible open system to challenge SIMS and there may be some people
who'd like to keep their eyes open for this. As far as I am aware there
is no online material to look at as yet.
