We talk about diagramming systems/networks/etc. for documentation purposes. Jthan’s 15 clams is a really useful one on methods for remotely decrypting FDE.

Just the Tip


Starts at 22m43s.

I was drinking Kraken Black Spiced Rum again. Paden was drinking PBR. Jthan was drinking Coors Banquet.

  • Diagramming Networks
    • Why/when to diagram?
      • For bringing in new employees
      • For reference/at-a-glance of inventory
      • Auditor use
      • Easier to phase out old hardware
    • Why not/when not to diagram?
      • LARGE environments (too cumbersome)
      • It can be hard to maintain for very dynamic environments; no documentation is almost better than old/obsolete documentation
    • Tools one can use to create diagrams

15 Clams

In this segment, Jthan shares with you a little slice of life. The title is a reference to this video. (2m16s in)

Starts at 50m45s.

Jthan wants to know how to remotely unlock LUKS-crypted FDE. Luckily, the Arch Wiki has a section on that. And you can do a LOT more with mkinitcpio hooks, such as wiping a disk with nwipe (the F/OSS, openly-developed, and vastly better fork of dwipe, the “active ingredient” of DBAN).

By the way, the source for Arch switching to Dracut can be found here.

  1. re: “How many ohms of resistance does a common household cat have”
    Depends. Is it long hair or short hair, wet or dry, “in heat”, is it on a “dry” diet, or “wet” diet.
    You have to specify test conditions and test setup/equipment under which measurements are made. Otherwise, results may be wildly variable.
