[ome-users] Accessing web interfaces from other computers

Right. I was wrong with the addition of the option, so it will
continue to be a problem. :) The proper way to get OMERO.web onto the
public network interface is to follow the production instructions
under:

https://www.openmicroscopy.org/site/documents/data-management/omero4/server/install-web

However, since I like you all so much, here's how you can go about
doing this, but as I told Jerome: development only!

Feel free to stop reading here. For anyone wanting to get their hands
dirtier with OMERO, please join the ome-devel mailing list:

http://lists.openmicroscopy.org.uk/mailman/listinfo/ome-devel/

The etc/grid/(win)default.xml and etc/grid/templates.xml files are
highly customizable, and are intended to let system administrators
configure exactly what processes are started where on their resources.

The ShellTemplate which is used to start OMERO.web on *nix machines,
simply calls: bin/omero server Web, which is why the change that Mark
suggested works.

The extra bit of work which "bin/omero server Web" does is to create
the initial django database. If you are willing to do this from the
commandline as outlined on install-web, then there's no reason to not
use the WebTemplate (which is used under Windows for various reasons).

SO...if you would like to add the <option>0.0.0.0:8000</option> entry
in default.xml, do so to WebTemplate and then change the line

  <server-instance template="ShellTemplate" id="Web" act="on-demand"/>

in etc/grid/default.xml to

  <server-instance template="WebTemplate"/>

And then let me know if you have any further questions. :)

Best wishes,
~Josh.
