timedicer-server-setup v8.46 [26 Feb 2024] by Dominic

Description

timedicer-server-setup.sh is part of the TimeDicer suite https://www.timedicer.co.uk, and sets up a TimeDicer Server or updates its existing setup.

It is normally run with -f option after the first boot of a new TimeDicer Server machine. It can be run subsequently with or without -f option to update the machine.

Usage

timedicer-server-setup.sh [option] [you@your_email_address.org]

Options

-v verbose (show normal output from commands)
-f run automatically assuming 'y' for all questions - email address on command line required
-h show this help

Details

Depending on the user's choices and existing installed software, timedicer-server-setup.sh configures the server as follows -
- download and extract key scripts from www.timedicer.co.uk (including self-updating this script)
- check and update timezone information [requires user response]
- download and install postfix, including optional relay authentication [requires user response]
- download and install updates for Ubuntu
- restrict access so that each user's /home folder is readable only by that user (and the administrator)
- download and install wakeonlan, lvm2, ssh, apache2, php
- bespoke settings for nano, php, postfix, cron, and enable apache2.conf
- create ssh keys for primary user and for root
- if root filesystem is encrypted, setup boot-time ssh to allow remote entering of encryption passphrase
- download and install rdiff-backup, Rdiffweb and incron
- start Rdiffweb, apache2 and postfix
- send a test email

Dependencies are shown and while in most cases written and tested on an x86-based Linux server, they should run on a Raspberry Pi, and many can run under Windows using Windows Subsystem for Linux (WSL) or Cygwin. Email me if you have problems or questions, or if you think I could help with a programming requirement.
