A Synology is basically a linux system, in a small case and with a nice web interface to do most basic tasks. For the tasks which do not run by default from the web interface, SSH can be used. This tutorial demonstrates how to set up passwordless SSH between two (or more) Synology boxes. This is very useful for automated tasks, such as automated backups.

In this tutorial we will have a local Synology and a remote Synology. The local Synology will be able to connect over SSH without a password, to the remote Synology.

Out of the box, Mac OS High Sierra ships with a 12 year old version of Rsync. The reason for this is that Apple doesn’t include anything released under GPLv3 or similar licenses.

Luckily, it’s relatively quick and simple to update Rsync using Homebrew.

Article extract The following is a modified extract from LXD, ZFS and bridged networking on Ubuntu 16.04 LTS. As bridged networking is quite a popular topic I felt it’s worth its own post to reduce the need to go looking for it in the longer guides I’ve written. I’ll also link to it from new guides going forward. NB: Ubuntu 12.04 LTS is the earliest release I’ve used this with. It should work on earlier versions as well, but your mileage may vary. Installation In order to set up a network bridge, the package bridge-utils needs to be installed. Install it with: sudo apt-get install … read more.
