SSH Cheat Sheet

This sheet goes along with this SSH YouTube tutorial

Login via SSH with password (LOCAL SERVER)

$ ssh brad@192.168.1.29

Create folder, file, install Apache (Just messing around)

$ mkdir test

$ cd test

shouro

# The various ${var.foo} come from variables.tf

# Specify the provider and access details
provider "aws" {
    region = "${var.aws_region}"
    access_key = "${var.aws_access_key}"
    secret_key = "${var.aws_secret_key}"
}

Initialise (will return keys and a token)

curl -X PUT http://0.0.0.0:8200/v1/sys/init --data '{"secret_shares":1, "secret_threshold":1}'

Use one of the keys to unseal

curl -X PUT http://0.0.0.0:8200/v1/sys/unseal --data '{"key":"a5e665962f544dd16471c120c5500a7906cfbaeb3f18ae0fc6c5c71d444f0a90"}'

Use the root token to store something

A simple unix/linux daemon in Python

I've written a simple Python class for creating daemons on unix/linux systems. It was pieced together for various other examples, mostly corrections to various Python Cookbook articles and a couple of examples posted to the Python mailing lists. It has support for a pidfile to keep track of the process. I hope it's useful to someone.

from Crypto.Cipher import AES

# the block size for the cipher object; must be 16, 24, or 32 for AES
BLOCK_SIZE = 32

# the character used for padding--with a block cipher such as AES, the value
# you encrypt must be a multiple of BLOCK_SIZE in length.  This character is
# used to ensure that your value is always a multiple of BLOCK_SIZE
