Introduction

This page lists the steps needed to create an ssh key for Biola System Administration use. We currently use ecdsa with 521 bits.

Step 1: Create an SSH Key

Run the following in terminal:

Linux

ssh-keygen -t ecdsa -b 521 -f ~/.ssh/desiredSSHKeyFilename

Introduction:

This Page shows how to make a SHA-512 hash. This is needed for creating a hash of a SysAdmin user account password as it allows other SysAdmins to set each other's passwords without knowing what the password is.

Workflow Prerequisites

A Linux or Mac computer.
- Linux: The mkpasswod binary (found in the whois package).
- Mac: Python3 and passlib

Create the Password Hash

First you'll want to manually create the Docker volumes:

docker volume create --driver local \
  --opt type=nfs \
  --opt o=addr=nfs_server_ip,rw,nolock,hard,nointr,nfsvers=4 \
  --opt device=:/path/to/nfs/share/on/server \
  nfs_share

docker volume create --driver local \

--opt type=cifs \

Use the DNS CNAME validation method to verify domain control

Digicert allows users to add a DNS CNAME record to demonstrate control over the domain they are creating a cert for.

This process can (and should) be done up to 30 days

How to verify domain control

Go to digicert.com and sign in.
Navigate to CERTIFICATES > Orders.
Search for the certificate name you need to validate the domain for.
Click on the certificate name.

Introduction

An SSH key is a credential used to access a device capable of running the SSH protocol. It consists of a public and private key pair that authenticate the user trying to access the device.

In a server environment, public ssh keys are added to an authorized_keys file in a user account. Once there, when a user attempts to access the server over ssh using their private ssh key, the server is able to authenticate the user and gives them access directly to their account.

Workflow Prerequisites

This workflow requires a Windows computer as PuTTY is a Windows-only application.
