rsync backup from Ubuntu server to Synology NAS

This tutorial describes how to do scripted passwordless encrypted automatic rsync backups from an Ubuntu server to a Synology NAS. It is supposed to be a general guide, which can be used with other Linux variants as well. Only minor changes should be required.

I did this first of all in order to help other Synology NAS users perform efficient and secure backups to their NAS, but also to get get my scratch pad like personal installation notes in a more reasonable shape, so I can recall later on myself what I did, how, and why.

Synology NAS shell – Basics

synology_dsmThe following article describes some basics regarding first contact with Synology DSM shell.

I used DSM 6.1.3 out of the box, running in a Virtual machine (using Virtual Machine Manager) on DS1817+ hardware.

Null client Postfix setup

The following setup describes a postix setup to send e-mails using an existing SMTP server. It is not designed to receive e-mails. My provider is DreamHost, but setup should be very similar with other hosters. I used a VM with the Ubuntu Server 16.04.1 out of the box installtion (ubuntu-16.04.1-server-amd64). This VM has no real FQDN, hence an imaginary needs to be configured in order to make the SMPT server accept sent e-mails.

Video tutorials

Below you see a QAD (quick and dirty) screenshot video tuorial which shows how to convert a roster using the www method. Screenshots taken on iPhone 6S (iOS 11.2.6). rostics 1.0.18-PL2 was used.

DNS Stock update script

dnsstock_update_screenshotThis script updates the DNS records of DNS Stock.

It generates an URL<domain>&username=<username>&password=<pass>&myip=<ipaddr>, which is eventually passed to the DNS Stock server. The code is basically about parsing, validating, checking and formatting the returned WAN IP <ipaddr>. Two URLs are configured to check WAN IP. If the first one returns an error, the second one is queried. If that one fails as well, the script abandons. The logfile dnsstock_update.log reveals relevant details about what happened.

Configured passwords can either be plain text (depreciated) or MD5 crypted (preferred), as visible on DNS Stock site. The DNS Stock server accepts both formats.

Code and logfile entries should be self-explanatory.


Comments are desired.


.htaccess rewrite of directory to new domain

Online files stored on a web server have, most of the time, many references pointing to these files.

In my case, my web hoster decided that I had to take away files stored in a folder called downloads. However many links from my phpbb3 forum pointed to that directory. Needless to say, that this would require a lot of manual work adjust all these links.
