Task list

Upgrade AUTH2 to Ubuntu 20.04

Hopefully last ever OS upgrade for AUTH2. So we can completely remove Quagga and BGP.

• Successfully upgraded but included few snags
  • PHP 5.6 ondrej package repository needed to be re-enabled and packages upgraded
  • /usr/bin/php needed to be repointed from 8.2 to 5.6
  • Disabled most strict modes for newly upgraded MySQL v8.0.32
  • Kohana's /srv/www/default/application/classes/model/entity.php need to be manually updated to always set $this->lastModified = new \DateTime(); in save function. Otherwise Kohana tries to initially explicitly set this to NULL but should not be set so the database can do this automatically because of this config: `last_modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT 'time the row was last modified',
  • FreeRadius 3 config needed re-inserting /etc/freeradius/3.0/
  • OpenVPN issues:
    • To be documented
  • Apache issues:
    • SOWN's ca.key was too small.
    • More to be documented
• Quagga was successfully removed and now only Bird2 remains which uses OSPF

New SG350-28 Switches

• Connected current console cable for Cisco 3750G and was immediately able to establish a session through GW-B32.
• Finish installing (using Ansible playbooks) new GW servers.
• Console interface looks much like that for certain DLink/NetGear managed switches
• Tim upgraded both switches to latest firmware using FAT32 formatted USB pen
• Tyler was able to directly import this device into NetBox

Rack second replacement UPS

• First replacement UPS successfully unracked and placed in the corner of the server room.
• Box for second replacement UPS retained if first replacement needs to be returned.
• Old rack rails for original UPS thrown away (in WEEE cage).

• Network module from first replacement UPS moved to second replacement.
• Second replacement UPS racked and powered up with no issues.
• All redundant power supplies server have one PSU connected to UPS, including lear and goneril from OFERTIE project. KVM, GW-B32 and BACKUP-B32-1 also connected on their single PSU.
