myprint.scl.utah.edu

The myprint service handles wireless printing for the MLIB PC labs. FreeBSD is the operating system that was chosen for this service primarily for its security features.

Details on the current configuration of myprint.scl.utah.edu can be found below. 07/12/2013

Host OS configuration

This first section details the various configuration options applied to the kernel, NAT & traffic passing to jailed (non routable net) env, usage of IPFW service to filter incoming & outgoing traffic to specific subnets & or targets, OS, Jail & TCP stack hardening options

# stop active raid
mdadm --stop /dev/md[01]

# destroy partition table on hdds
dd if=/dev/zero of=/dev/sda bs=1M count=512
dd if=/dev/zero of=/dev/sdb bs=1M count=512

# create new partition table
sgdisk -og /dev/sda

YubiKey 4 series GPG and SSH setup guide

Written for fairly adept technical users, preferably of Debian GNU/Linux, not for absolute beginners.

You'll probably be working with a single smartcard, so you'll want only one primary key (1. Sign & Certify) and two associated subkeys (2. Encrypt, 3. Authenticate). I've published a Bash function which automates this slightly special key generation process.

On-premise LLM model deployments

Requirements

LLM models used as an external resource offer multiple disadvantages:

Privacy - guarantees regarding confidential imformation usage by the models and intellectual property (IP) safety cannot be guaranteed
Flexibility - specialization and fine-tuning of more general models offers efficiency gains in terms of resources used and outputs achieved
Stability - reducing vendor dependency allows internal system stability through guaranteed availability

An approach, whereby LLM models and deployed, fine-tuned and utilized locally (on-premise) allows:

	class Canvas
	attr_reader :width
	attr_reader :height

	def initialize(input)
	vals = input.split
	@width = vals[0].to_i
	@height = vals[1].to_i
	@all = Array.new(@width * @height, 0)
	end

	# to generate your dhparam.pem file, run in the terminal
	openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048
