Review last meeting's Action Items

• suexec-flex https://rt.uwaterloo.ca/Ticket/Display.html?id=950947
  • Nathan to discuss with Lori and Issac to determine who should be rebuilding the package and redistributing the deb patch
    • Progress?
      • Dave's view of the long run, is that this work would be one of the responsibilities of the empty INF position. I just don't see current INF staffing being able to take this until later in Winter term (maybe as part of final Ubuntu 22.04 cleanup to go production).
    • Nathan gathering info from package authors and following up.
  • Need documentation for this project and some example test cases to motivate new developers.
  • Is there a .deb package at this point that is ready for distribution?
    • nfish is working on it
• Ubuntu 22.04 availability
  • No 100G ring access yet for LXC instances, waiting on layer 1 equipment
  • Dave will help Anthony with layer 1 needs.
    • This is now done.
• Separation of TEACHING and GENERAL VLANs: this is a CS legacy separation, do we believe IST's firewall config is sufficient to maintain this?
  • What exactly is the requirement here? Are we actually meeting the requirement at present? Have we ever?
  • The separation that is being questioned is at layer 2.
  • There appear to be serious security origins and implications of these decisions (e.g. a TEACHING user sniffing GENERAL network traffic and gaining unencrypted data; how much of a risk is this?)
  • The work required for this is non-trivial (time) and current design/maintenance activity proceeds without assuming any separation at layer 2. Is this OK ?
  • O needs to gather more info. Will start with managers. iang, pabuhr are faculty that may be good starts for a faculty sample for this.
