Current Projects

This is the list we will work from in addition to service requests.

Some important procedural pages:

• Use the Sysadmin task template if you're starting a new project. Copy and paste the wiki source page and populate the basic fields.
• This is a new way of task processing. It's subject to change.
• You can see our Open Tasks here.
• We will also start filling up the Closed Tasks category.
• Documentation - please click here to update projects you've worked on but haven't documented yet

Please update specific projects at their own page.

• Web logins
• Password management
• Docker and WebODM on Bronte
• Fix shinken server access
• Verify Lovelace DNS - update the DNS file and this will be done
• Layout Layout
• Backup in Lilly basement
• Power map additions and updates
• Backup on all machines - includes backup.cs.e.e (indiana?)
• Fix Lovelace machines
• Post shutdown
