====== Blade ======

===== Purpose =====

''blade.hackeriet.no'' is a service VM used by several Hackeriet services.

For inventory details, use the NetBox/IPAM entry ''blade'' (VM ID ''12''). NetBox is the source of truth for VM size, IP assignments, site, tenant, and current placement.

===== Emergency Access =====

Normal access:

  * ''ssh blade.hackeriet.no''

If SSH does not respond:

  - Open the NetBox/IPAM entry ''blade''.
  - Confirm the current hypervisor from NetBox before assuming placement.
  - Current known hypervisor when this page was written: ''host007''.
  - Connect to the Proxmox UI/console for the current hypervisor or cluster.
  - Cluster name from NetBox: ''klynge001''.

The VM can move, so always verify placement in NetBox during an incident.

===== Credentials =====

Do not paste secrets into the wiki.

Relevant ''hackeriet/pass'' entries:

  * ''hackeriet@blade.hackeriet.no.gpg''
  * ''mailman@blade.gpg''

If root or service credentials are needed, look in ''hackeriet/pass'' and keep decrypted values out of the wiki.

Observed over SSH on 2026-05-19:

  * OS: ''Debian GNU/Linux 13 (trixie)''
  * Kernel: ''6.12.88+deb13-amd64''

Treat this as emergency orientation only. Live state may differ.
