## Known Broken Stuff
- IPv6 inbound
  - ACTION: [TEC] to email UWA IT
- lard
  - Still needs a spare PSU OR replacement with something less... fatty.
  - ACTION: [???] to send email out requesting a 1U Cisco switch to replace Lard
- samson the https://wiki.ucc.asn.au/ActiveDirectory server has no freshly built DC friends
  - this is risky, a single-point-of-failure, which in turn depends on the running VM cluster
  - something to do with the current configuration is probably why mussel
    and mooneye still have auth problems
    - can we upgrade or rebuild or document our way out of this?
  - ...so making a quick clone and calling it "done" really isn't enough, continuous integration is called for?
  - vucc testbed in https://wiki.ucc.asn.au/NewActiveDirectory

## Matters arising previously

## Extra items (rename/refile as appropriate)
- Monitoring
  - Drive health
    - Uncorrectable errors, reallocated sectors, TBW on SSDs
    - ACTION: [NTU] and [MTL] to work together on how best to start drive monitoring, and make it standard/SOE config via ansible

- [MTL] continues looking at DNS
  - Not much progress
  - Have played with coredns for a resolving server
    - Need to do some more testing of resolving internal UWA things (to check behaviours)
  - Working on ansible to set up a primary DNS server
  - Done a little bit of playing with Gitlab CI
  - Need to finalise working out the best way to do this securely
    - split out ucc.machines from zonemake.py code

- Group Policy and Ansible on Windows machines
  - ACTION: [333] to figure out most supported way to install official SSHD build on Windows
  - ACTION: [MTL] promises to look at this in more detail once back in the clubroom, including WinRM
  - Best host to run playbooks from for the Windows machines?

- Post-O-Day account locking
  - cleanup accounts e.g. `getent passwd|grep zv`, primary group memberships
  - ACTION: [TEC] and [MPT] still need to get this sorted
    - Specifically, the Comite™ get a list of people who haven't paid and send to Wheel, so we can do the locking, if James and Tim don't do the locking themselves

- Staging storage server:
  - A DELL R710 would do nicely
  - [TEC] Old DELL R710 servers from dadams
  - ACTION: [NTU] followup the previously budgetted 3.5" bulk backup drive purchase
    - Email: https://lists.ucc.gu.uwa.edu.au/pipermail/tech/2021-March/005446.html

- [MPT] Began (unofficial) discussions with [DBA] and CS faculty about making GPU compute accessible to students
  - Potential for funding? No assurances yet
  - What else would UCC need to buy/build to make it happen in our MR?

- ACTION: [MTL] to update Ansible scripts for mail*
  - In response to spam campaign

- Build and break a PC
  - Brand new motherboard missing audio capacitor, but [DBA] will resolder it
    - ACTION: [DBA] to resolder audio capacitor on new motherboard
