Calibre Server on Linux

Introduction

Calibre is a powerful cross-platform, open source, ebook manager and editing platform. Its calibre-server component can be used to publish an e-book library on a local network. While you can launch calibre-server as a desktop application, it can also be run as a daemon on a headless Linux server.

This tutorial on setting up calibre-server using Ubuntu 14.04 is very good, but dated.

Introduction

The purpose of this short howto is to show you how to:

use openconnect [1] to connect to an enterprise cisco anyconnect endpoint
whilst minimizing the amount of traffic that your route through the vpn connection

Usually VPN administrators will puth the default route to the users, so that all user traffic is routed through the vpn connection. This is to address the various security concerns around compromised user computers bridging external internet traffic into the secure VPN network.

While the VPN administrator can push routes to the clients, the client can ignore these default routes and establish client side routing so that only the required A.B.C.D/E network is routed through the VPN. All other traffic will still use the clients default route and default outbound internet connection.

	# This gist gives instructions to build a basic deb package of netatalk-3.1.11 using checkinstall on Ubuntu 18.04.
	# With the idea being that you build the deb on your build server and install from the resulting deb in production.
	# Given that the deb is packaged using checkinstall with basic options, think home use, not real production.

	# Note that this build does not provide the spotlight feature.
	# The tracker packages have been left out as the intent was to provide TimeMachine functionality only.
