  3. local (anything in the process of being worked upon)
  4. picture (photographs, art, etc)

Maintenance tasks @arc-de

To do:

  • Update OS to FreeBSD-RELEASE 11.1
  • Update packages, especially Samba
  • Tweak PF Firewall
  • Add blacklistd, and include in firewall rules
  • Install backup software
  • Start backup (possibly complete)
  • Setup the KVM Spider Duo
  • Check backup is running fine
  • If needed, tweak backup procedure
  • Perform log archiving and rotation
  • See if there are any other maintenance chores left


I will need a small monitor to hook up to the server and US keyboard.
