[LON-CAPA-admin] Cloning production server for testing purposes

[Lucas, Mark]

Stefan,

I'm not sure localenroll.pm will do what you think. It's for the auto enrollment process, isn't
it? Or is there a routine in there that filters logins?

Under system configuration you can redirect logins to a different machine except for from certain
IP addresses. The only hitch I realized is that as far as I can tell, it has to be another machine in
the cluster, which is hard to do when it's out of the cluster.

The nice thing is that the emails are showing up within a few minutes of going out. Thank you,
Stuart, for updating mailman!

Thanks, Mark. This is helpful.

To assure that no others than the tester personnel can login, I think I
will adjust localenroll.pm.

By the way: Funny to find your answer in my inbox before the actual
question... :-)

We have a development server that has the hostname oucapa2 and domain ohiou,
the same as our main library server.

Since it is in the development cluster, none of the machines in the
production cluster
know of it's existence. It does not interfere or confuse the production
cluster.

It has a different IP address than the regular library server and
different hosts.tab and domain.tab.

The only real risk is that a student somehow gets logged into the wrong
machine by
somehow getting the IP address of the development server (not a high
risk in my mind).

At the last meeting we were actually talking about setting up a small
cluster in between
development and production, which cloned the full library servers at
several of the institutions.
This would provide a close-to-production environment for LC 3.0 testing.

Hope this helps!

Hi,

To avoid chaos, I want to make sure that my idea works.

I'd like to clone one of our production servers for testing purposes. I
do not need connection to the LON-CAPA cluster but I want to have all
local users, problems and courses as well as the related data.

Is it really okay to "copy" the whole server, configure it as
"standalone" and connect it to the internet? Copy means to process most
of the steps as described on http://loncapa.org/hardwareupgrade.html
which is basically copying the home folder.

Even not connecting it to the internet could mean to have two very
similar servers in the same local network, e.g. domain and host id would
be the same.

Thanks in advance for sharing any doubts,
Stefan Bisitz
