The roles of Squash and Crossroads-B have changed. They are no longer running the Crossroads daemons for the labs, and the access permissions on a per-directory basis are not as robust as we'd like. The current OS (Server 2000) does not provide a granular enough method of restricting access to test materials, which means that we need to set permissions on test directories manually each time (and then turn them off later).
By installing Windows 2003 Server we can set up a permissions cascade that allows direct access to a specific file, but does not allow read access to any of the parent directorie(s). This should mean that we can set read perms on test directories for instructors only. They can then find the test file and send it, and the students can receive it, but not browse for it. The only wrinkle in this cunning plan is that we'll need a complete list of NetLinkIDs for all instructors. There may be a solution in LDAP, however. If I can set permission on test dirs based on the user's role, which is had by querying UVic's LDAP DB.
So the task is:
Rebuild Crossroads-B with Windows 2003 Server.
Put in a second drive for data.
RoboCopy all the teachingmaterials from Squash to the data drive.
Write a script to mirror the squash\teachingmaterials directory regularly.
Make it a file server.
Enter it in to the domain.
Put it in the server room, add it to the IP database, and give it a static IP.
Test accessibility via Sanako apps in Labs.
Research/Install/Configure LDAP connection to accommodate cunning plan above.
Test cunning plan.
