					Title: My Backup Strategy
 | 
				
			||||||
 | 
					Date: 2021-04-08
 | 
				
			||||||
 | 
					Category: Writing
 | 
				
			||||||
 | 
					Summary: Details about the backup system for all of my data.
 | 
				
			||||||
 | 
					Wide: true
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					[TOC]
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Regularly backing up all the data I care about is very important to me. This
 | 
				
			||||||
 | 
					article outlines my strategy to make sure I never lose essential data.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## Motivation
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Backups should be as automatic as possible. This ensures laziness and
 | 
				
			||||||
 | 
					forgetfulness won't interfere with the regularity.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					All software used to create and store the backups should be free and open source
 | 
				
			||||||
 | 
					so I'm not depending on the survival of a company.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Backups need to be tested to ensure they are correct and happening regularly.
 | 
				
			||||||
 | 
					Multiple copies of the backups should exist, including at least one offsite to
 | 
				
			||||||
 | 
					protect against my building burning down.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Backups should also be incremental when possible (rather than mirror copies) so
 | 
				
			||||||
 | 
					an accidental deletion isn't propagated into the backups, making the file
 | 
				
			||||||
 | 
					irrecoverable.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## Strategy
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I have one backup folder `/mnt/backup` on my media server at home that serves as
 | 
				
			||||||
 | 
					the destination for all my backup sources. All scheduled automatic backups write
 | 
				
			||||||
 | 
					to their own subfolder inside of it.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					This backup folder is then synced to encrypted 2.5" 1 TB hard drives which I
 | 
				
			||||||
 | 
					rotate between my bag, offsite, and my parents' house.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## Backup Sources
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I use the tool `rdiff-backup` extensively because it allows me to take
 | 
				
			||||||
 | 
					incremental backups locally or over SSH. It acts very similar to `rsync` and has
 | 
				
			||||||
 | 
					no configuration.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### Email
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I have every email since 2010 backed up continuously in case my email provider
 | 
				
			||||||
 | 
					disappears.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I use `offlineimap` to sync my mail to the directory `~/email` on my media
 | 
				
			||||||
 | 
					server as a Maildir. Since offlineimap is only a syncing tool, the emails need
 | 
				
			||||||
 | 
					to be copied elsewhere to be backed up. I run `rdiff-backup` from a weekly cron
 | 
				
			||||||
 | 
					job:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					<span class="aside">I'll explain what backup_check.txt does below</span>
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					*/15 * * * * offlineimap > /var/log/offlineimap.log 2>&1
 | 
				
			||||||
 | 
					00 12 * * 1 date -Iseconds > /home/email/email/backup_check.txt
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					20 12 * * 1 rdiff-backup /home/email/email /mnt/backup/local/email/
 | 
				
			||||||
 | 
					40 12 * * 1 rdiff-backup --remove-older-than 12B --force /mnt/backup/local/email/
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Here's my `.offlineimaprc` for reference:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					[general]
 | 
				
			||||||
 | 
					accounts = main
 | 
				
			||||||
 | 
					[Account main]
 | 
				
			||||||
 | 
					localrepository = Local
 | 
				
			||||||
 | 
					remoterepository = Remote
 | 
				
			||||||
 | 
					[Repository Local]
 | 
				
			||||||
 | 
					type = Maildir
 | 
				
			||||||
 | 
					localfolders = ~/email
 | 
				
			||||||
 | 
					[Repository Remote]
 | 
				
			||||||
 | 
					type = IMAP
 | 
				
			||||||
 | 
					readonly = True
 | 
				
			||||||
 | 
					folderfilter = lambda foldername: foldername not in ['Trash', 'Spam', 'Drafts']
 | 
				
			||||||
 | 
					remotehost = example.com
 | 
				
			||||||
 | 
					remoteuser = mail@example.com
 | 
				
			||||||
 | 
					remotepass = supersecret
 | 
				
			||||||
 | 
					sslcacertfile = /etc/ssl/certs/ca-certificates.crt
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### Notes
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I use Standard Notes to take notes and wrote the tool
 | 
				
			||||||
 | 
					[standardnotes-fs](https://github.com/tannercollin/standardnotes-fs) to mount my
 | 
				
			||||||
 | 
					notes as a file system to view and edit them as plain text files.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I take weekly backups of the mounted file system on my media server with cron:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					00 12 * * 1 date -Iseconds > /home/notes/notes/backup_check.txt
 | 
				
			||||||
 | 
					15 12 * * 1 rdiff-backup /home/notes/notes /mnt/backup/local/notes/
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### Nextcloud
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I self-host a Nextcloud instance to store all my personal documents (non-code
 | 
				
			||||||
 | 
					projects, tax forms, spreadsheets, etc.). Since it's only a syncing software,
 | 
				
			||||||
 | 
					the files need to be copied elsewhere to be backed up.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I take weekly backups of the Nextcloud data folder with cron:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					00 12 * * 1 rdiff-backup /var/www/nextcloud/data/tanner/files /mnt/backup/local/nextcloud/
 | 
				
			||||||
 | 
					30 12 * * 1 rdiff-backup --remove-older-than 12B --force /mnt/backup/local/nextcloud/
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### Gitea
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I self-host a Gitea instance to store all my git repositories for code-based
 | 
				
			||||||
 | 
					projects. My home folder is also a git repo so I can easily sync my config files
 | 
				
			||||||
 | 
					and password database between servers and machines.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I take weekly backups of the Gitea data folder with cron:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					00 12 * * 1 date -Iseconds > /home/gitea/gitea/data/backup_check.txt
 | 
				
			||||||
 | 
					10 12 * * 1 rdiff-backup --exclude **data/indexers --exclude **data/sessions /home/gitea/gitea/data /mnt/backup/local/gitea/
 | 
				
			||||||
 | 
					35 12 * * 1 rdiff-backup --remove-older-than 12B --force /mnt/backup/local/gitea/
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### Telegram
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Telegram Messenger is my main app for communication. My parents, most of my
 | 
				
			||||||
 | 
					friends, and friend groups are on there so I don't want to lose those messages
 | 
				
			||||||
 | 
					in case Telegram disappears or my account gets banned.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					<span class="aside">Saves the messages to a sqlite db</span>
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Telegram includes a data export feature, but it can't be automated. Instead I
 | 
				
			||||||
 | 
					run the deprecated software
 | 
				
			||||||
 | 
					[telegram-export](https://github.com/expectocode/telegram-export) hourly with
 | 
				
			||||||
 | 
					cron:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					0 * * * * bash -c 'timeout 50m /home/tanner/opt/telegram-export/env/bin/python -m telegram_export' > /var/log/telegramexport.log 2>&1
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					It likes to hang, so `timeout` kills it if it's still running after 50 minutes.
 | 
				
			||||||
 | 
					Hasn't corrupted the database yet.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### Phone
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					[Signal
 | 
				
			||||||
 | 
					Messenger](https://play.google.com/store/apps/details?id=org.thoughtcrime.securesms&hl=en_CA&gl=US)
 | 
				
			||||||
 | 
					automatically exports a copy of my text messages database, and
 | 
				
			||||||
 | 
					[Aegis](https://play.google.com/store/apps/details?id=com.beemdevelopment.aegis&hl=en_CA&gl=US)
 | 
				
			||||||
 | 
					allows me to export an encrypted JSON file of my two-factor authentication
 | 
				
			||||||
 | 
					codes.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I mount my phone's internal storage as a file system on my desktop using
 | 
				
			||||||
 | 
					[adbfs-rootless](https://github.com/spion/adbfs-rootless). I then rsync the
 | 
				
			||||||
 | 
					files over to my media server:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ ./adbfs ~/mntphone 
 | 
				
			||||||
 | 
					$ time rsync -Wav \
 | 
				
			||||||
 | 
					  --exclude '*cache' --exclude nobackup \
 | 
				
			||||||
 | 
					  --exclude '*thumb*' --exclude 'Telegram *' \
 | 
				
			||||||
 | 
					  --exclude 'collection.media' \
 | 
				
			||||||
 | 
					  --exclude 'org.thunderdog.challegram' \
 | 
				
			||||||
 | 
					  --exclude '.trashed-*' --exclude '.pending-*' \
 | 
				
			||||||
 | 
					  ~/mntphone/storage/emulated/0/ \
 | 
				
			||||||
 | 
					  localmediaserver:/mnt/backup/files/phone/
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Unfortunately this is a manual process because I need to plug my phone in each
 | 
				
			||||||
 | 
					time. Ideally it would happen automatically while I'm asleep and the phone is
 | 
				
			||||||
 | 
					charging.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### Miscellaneous Files
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					The directory `/backup/files` is a repository for any kind of files I want to
 | 
				
			||||||
 | 
					keep forever. My phone data, old archives, computer files, Minecraft worlds,
 | 
				
			||||||
 | 
					files from previous jobs, and so on.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					All the files will be included in the 1 TB hard drive backup rotations.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### Web Services
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Web services that I run like [txt.t0.vc](https://txt.t0.vc) and
 | 
				
			||||||
 | 
					[QotNews](https://news.t0.vc) are backed up daily, weekly, and monthly depending
 | 
				
			||||||
 | 
					on how frequently the data changes.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I run `rdiff-backup` on the remote server with cron:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					00 14 * * * date -Iseconds > /home/tanner/tbot/t0txt/data/backup_check.txt                                                  
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					04 14 * * * rdiff-backup /home/tanner/tbot/t0txt/data tbotbak@remotebackup::/mnt/backup/remote/tbotbak/daily/t0txt/
 | 
				
			||||||
 | 
					14 14 * * * rdiff-backup --remove-older-than 12B --force tbotbak@remotebackup::/mnt/backup/remote/tbotbak/daily/t0txt/
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					24 14 * * 1 rdiff-backup /home/tanner/tbot/t0txt/data tbotbak@remotebackup::/mnt/backup/remote/tbotbak/weekly/t0txt/
 | 
				
			||||||
 | 
					34 14 * * 1 rdiff-backup --remove-older-than 12B --force tbotbak@remotebackup::/mnt/backup/remote/tbotbak/weekly/t0txt/
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					44 14 1 * * rdiff-backup /home/tanner/tbot/t0txt/data tbotbak@remotebackup::/mnt/backup/remote/tbotbak/monthly/t0txt/
 | 
				
			||||||
 | 
					55 14 1 * * rdiff-backup --remove-older-than 12B --force tbotbak@remotebackup::/mnt/backup/remote/tbotbak/monthly/t0txt/
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					The `tbotbak` user has write access to the `/mnt/backup/remote/tbotbak`
 | 
				
			||||||
 | 
					directory only. It has its own passwordless SSH key that's only permitted to run
 | 
				
			||||||
 | 
					the `rdiff-backup --server` command for security.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### Protospace
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I run a lot of services for [Protospace](https://protospace.ca/), my city's
 | 
				
			||||||
 | 
					makerspace.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					The member portal I wrote called [Spaceport](https://my.protospace.ca/) creates
 | 
				
			||||||
 | 
					an archive I download daily:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					40 10 * * * wget --content-disposition \
 | 
				
			||||||
 | 
					  --header="Authorization: secretkeygoeshere" \
 | 
				
			||||||
 | 
					  --directory-prefix /mnt/backup/remote/portalbak/ \
 | 
				
			||||||
 | 
					  --no-verbose --append-output=/var/log/portalbackup.log \
 | 
				
			||||||
 | 
					  https://api.my.protospace.ca/backup/
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					The website and [wiki](https://wiki.protospace.ca) that I sysadmin get
 | 
				
			||||||
 | 
					backed up weekly:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					0 12 * * 1 mysqldump --all-databases > /var/www/dump.sql
 | 
				
			||||||
 | 
					15 12 * * 1 date -Iseconds > /var/www/backup_check.txt
 | 
				
			||||||
 | 
					20 12 * * 1 rdiff-backup /var/www pshostbak@remotebackup::/mnt/backup/remote/pshostbak/weekly/www/
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					The Protospace [Minecraft
 | 
				
			||||||
 | 
					server](http://games.protospace.ca:8123/?worldname=world&mapname=flat&zoom=3&x=74&y=64&z=354)
 | 
				
			||||||
 | 
					I run gets backed up daily:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					00 15 * * * date -Iseconds > /home/tanner/minecraft/backup_check.txt
 | 
				
			||||||
 | 
					00 15 * * * rdiff-backup --exclude **CoreProtect --exclude **dynmap /home/tanner/minecraft psminebak@remotebackup::/mnt/backup/remote/psminebak/
 | 
				
			||||||
 | 
					30 15 * * * rdiff-backup --remove-older-than 12B --force psminebak@remotebackup::/mnt/backup/remote/psminebak/
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I also back up our Google Drive with rclone:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					45 12 * * 1  rclone copy -v protospace: /mnt/backup/files/protospace/google-drive/
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## Backup Copies
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					My backup folder `/mnt/backup` now looks like this:
 | 
				
			||||||
 |

					This directory tree is the master backup and I make a copy of the entire tree
 | 
				
			||||||
 | 
					every Saturday to a hard drive.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					The directory is copied over with the following script:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```text
 | 
				
			||||||
 | 
					#!/bin/bash
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					cryptsetup luksOpen /dev/sdf external
 | 
				
			||||||
 | 
					mount /dev/mapper/external /mnt/external
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					time rsync -av --delete /mnt/backup/local/ /mnt/external/backup/local/
 | 
				
			||||||
 | 
					time rsync -av --delete /mnt/backup/remote/ /mnt/external/backup/remote/
 | 
				
			||||||
 | 
					time rdiff-backup --force -v5 /mnt/backup/files/ /mnt/external/backup/files/
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					python3 /home/tanner/scripts/checkbackup.py
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					umount /mnt/external
 | 
				
			||||||
 | 
					cryptsetup luksClose external
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I wrote a Python script `checkbackup.py` that goes through each backup and
 | 
				
			||||||
 | 
					compares the timestamp in `backup_check.txt` files to the current time. This
 | 
				
			||||||
 | 
					makes sure that the cron ran, backups were taken, and transferred over
 | 
				
			||||||
 | 
					correctly.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## Rotating Hard Drives
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I rotate through 2.5" 1 TB hard drives each Saturday when I do a backup. They
 | 
				
			||||||
 | 
					are quite cheap at [$65 CAD](https://www.memoryexpress.com/Products/MX65194)
 | 
				
			||||||
 | 
					each so I can have a bunch floating around.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I keep one connected to the server, one in my bag, one offsite, one at my
 | 
				
			||||||
 | 
					mother's house, and one at my dad's house. Every Saturday I run the script above
 | 
				
			||||||
 | 
					to take a copy and then swap the drive with the one in my bag. It then gets
 | 
				
			||||||
 | 
					<span class="aside">I go back home about twice per year</span>
 | 
				
			||||||
 | 
					swapped when I visit my offsite location. Same for when I visit my parents. This
 | 
				
			||||||
 | 
					means that all hard drives eventually get rotated through with new data and
 | 
				
			||||||
 | 
					don't sit too long unpowered.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					The drives are all encrypted with full-disk LUKS encryption using a password I'm
 | 
				
			||||||
 | 
					unlikely to forget.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I run the check-summing `btrfs` file system on them in RAID-1 to protect against
 | 
				
			||||||
 | 
					bitrot. This means I can only use 0.5 TB of storage for my backups, but the data
 | 
				
			||||||
 | 
					is stored redundantly.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Here's how I set up new hard drives to do this:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ sudo cryptsetup luksOpen /dev/sdf external
 | 
				
			||||||
 | 
					$ sudo mkfs.btrfs -f -m dup -d dup /dev/mapper/external
 | 
				
			||||||
 | 
					$ sudo mount /dev/mapper/external /mnt/external/
 | 
				
			||||||
 | 
					$ sudo mkdir /mnt/external/backup
 | 
				
			||||||
 | 
					$ sudo chown -R tanner:tanner /mnt/external/backup
 | 
				
			||||||
 | 
					$ sudo umount /mnt/external
 | 
				
			||||||
 | 
					$ sudo cryptsetup luksClose external
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## Future Improvements
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I'm working on a system to automatically back up all my home directories to my
 | 
				
			||||||
 | 
					media server. I need this to grab Bash histories and code that's
 | 
				
			||||||
 | 
					work-in-progress. I've been burned by not having this once when a server died.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I'd like to automate backing up my phone by connecting it to a Raspberry Pi when
 | 
				
			||||||
 | 
					I go to sleep.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I need to get better at fully testing my backups by restoring them on a blank
 | 
				
			||||||
 | 
					machine.

					Title: Bypassing ISP Blocked Ports
 | 
				
			||||||
 | 
					Date: 2021-04-10
 | 
				
			||||||
 | 
					Category: Writing
 | 
				
			||||||
 | 
					Summary: Bypass ISP blocked ports using VPN port forwarding for public access.
 | 
				
			||||||
 | 
					Wide: true
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					[TOC]
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					My residential ISP blocks inbound traffic to common ports like 22, 80, and 443.
 | 
				
			||||||
 | 
					I use an OpenVPN tunnel to forward these ports so that I can self-host a
 | 
				
			||||||
 | 
					public media server. It does __not__ require users to be on the VPN.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					This article explains how I set it up and is targeted towards Linux sysadmins.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## Overview
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I have a cheap $5 per month virtual server with [Digital
 | 
				
			||||||
 | 
					Ocean](https://digitalocean.com) that runs Debian GNU/Linux 10. An OpenVPN
 | 
				
			||||||
 | 
					server is running on this virtual server.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					My media server at home has an OpenVPN client connected to the server and is
 | 
				
			||||||
 | 
					assigned a static IP on the VPN network.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					The virtual server has routing enabled and forwards inbound traffic __from the
 | 
				
			||||||
 | 
					internet__ to my media server at home. This allows me to have external HTTP and SSH
 | 
				
			||||||
 | 
					access.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## Server Setup
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Spin up a Debian 10 virtual server on your favourite hosting provider and set
 | 
				
			||||||
 | 
					your user up as you would normally. You should probably harden this server.
 | 
				
			||||||
 | 
					Assign a subdomain to it like `vpn.example.com`.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Install the following requirements:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ sudo apt update
 | 
				
			||||||
 | 
					$ sudo apt install openvpn ufw
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### OpenVPN Server
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					These steps roughly follow [this
 | 
				
			||||||
 | 
					guide](https://wiki.debian.org/OpenVPN#TLS-enabled_VPN).
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Generate TLS certificates and keys:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ cd /etc/openvpn
 | 
				
			||||||
 | 
					$ sudo openvpn --genkey --secret static.key
 | 
				
			||||||
 | 
					$ sudo make-cadir easy-rsa/
 | 
				
			||||||
 | 
					$ sudo chown -R tanner:tanner easy-rsa/
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Replace `tanner` with your own username, this is temporary.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					<span class="aside">The `.rnd` file prevents a warning</span>
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ cd easy-rsa/
 | 
				
			||||||
 | 
					$ ./easyrsa init-pki
 | 
				
			||||||
 | 
					$ head /dev/urandom > pki/.rnd
 | 
				
			||||||
 | 
					$ ./easyrsa build-ca
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Enter a password you won't forget in case you want to add another client later.
 | 
				
			||||||
 | 
					The Common Name you choose is not important.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Generate Diffie–Hellman params:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ ./easyrsa gen-dh
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Generate a server cert:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ ./easyrsa build-server-full server nopass
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Generate a client cert:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ ./easyrsa build-client-full mediaserver nopass
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					We make a `mediaserver` client because we want to assign a static IP to it. You
 | 
				
			||||||
 | 
					need to make a different one for each client you want with a static IP.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Also, if you want generic clients that all get dynamic IPs for use on your
 | 
				
			||||||
 | 
					laptop, phone, etc. to protect you from public WiFi, create only a single extra one:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ ./easyrsa build-client-full client nopass  # optional
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Leave off `nopass` if you want to password protect the config file keys when you
 | 
				
			||||||
 | 
					set up a new client.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Create the server config file `/etc/openvpn/server.conf`:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					<span class="aside">Can't use port 443 here since it'll be forwarded</span>
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					port 1194
 | 
				
			||||||
 | 
					proto udp
 | 
				
			||||||
 | 
					dev tun

			||||||
 | 
					topology subnet
 | 
				
			||||||
 | 
					ca /etc/openvpn/easy-rsa/pki/ca.crt
 | 
				
			||||||
 | 
					cert /etc/openvpn/easy-rsa/pki/issued/server.crt
 | 
				
			||||||
 | 
					key /etc/openvpn/easy-rsa/pki/private/server.key
 | 
				
			||||||
 | 
					dh /etc/openvpn/easy-rsa/pki/dh.pem
 | 
				
			||||||
 | 
					tls-auth /etc/openvpn/static.key 0
 | 
				
			||||||
 | 
					client-config-dir /etc/openvpn/ccd
 | 
				
			||||||
 |

					client-to-client

			||||||
 | 
					duplicate-cn
 | 
				
			||||||
 | 
					keepalive 10 120
 | 
				
			||||||
 | 
					cipher AES-256-GCM
 | 
				
			||||||
 | 
					auth SHA256
 | 
				
			||||||
 | 
					comp-lzo
 | 
				
			||||||
 | 
					max-clients 10
 | 
				
			||||||
 | 
					user nobody
 | 
				
			||||||
 | 
					group nogroup
 | 
				
			||||||
 | 
					persist-key
 | 
				
			||||||
 | 
					persist-tun
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Assign a static IP + chmod:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ cd /etc/openvpn
 | 
				
			||||||
 | 
					$ sudo chown -R root:root easy-rsa/
 | 
				
			||||||
 | 
					$ sudo mkdir ccd
 | 
				
			||||||
 | 
					$ sudo touch ccd/mediaserver
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Replace `mediaserver` with whatever client name you used above. Edit it like so:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					<span class="aside">Your home server will be `10.8.0.100`</span>
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					ifconfig-push 10.8.0.100 255.255.255.0
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Test your config by running:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ sudo openvpn --config /etc/openvpn/server.conf
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					If you run `ip addr` in another terminal, you should see an entry like this:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					5: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> stuff
 | 
				
			||||||
 | 
					    link/none 
 | 
				
			||||||
 | 
					    inet 10.8.0.1/24 brd 10.8.0.255 scope global tun0
 | 
				
			||||||
 | 
					       valid_lft forever preferred_lft forever
 | 
				
			||||||
 | 
					    inet6 fe80::d9fc:b2f9:34e6:5ed2/64 scope link stable-privacy 
 | 
				
			||||||
 | 
					       valid_lft forever preferred_lft forever
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### systemd
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					If it works fine, persist OpenVPN with systemd:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ sudo systemctl enable openvpn@server
 | 
				
			||||||
 | 
					$ sudo systemctl start openvpn@server
 | 
				
			||||||
 | 
					$ sudo systemctl daemon-reload
 | 
				
			||||||
 | 
					$ sudo service openvpn restart
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Test it works by rebooting:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ sudo reboot
 | 
				
			||||||
 | 
					$ ssh vpn.example.com
 | 
				
			||||||
 | 
					$ ip addr
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### Port Forwarding
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					I use `ufw` to handle the iptables rules because I use it anyway as a firewall
 | 
				
			||||||
 | 
					when I harden my servers.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Enable routing:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ sudo sysctl net.ipv4.ip_forward=1
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Edit `/etc/sysctl.conf` to set:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					net.ipv4.ip_forward=1
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Edit `/etc/default/ufw` to set:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					DEFAULT_FORWARD_POLICY="ACCEPT"
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Add this to the top of `/etc/ufw/before.rules`:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					*nat
 | 
				
			||||||
 | 
					:POSTROUTING ACCEPT [0:0]
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					# ssh port forwarding
 | 
				
			||||||
 | 
					-A PREROUTING -d 123.123.123.123 -p tcp --dport 2222 -j DNAT --to-dest 10.8.0.100:2222
 | 
				
			||||||
 | 
					-A POSTROUTING -d 10.8.0.100 -p tcp --dport 2222 -j SNAT --to-source 10.8.0.1
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					# Allow traffic from OpenVPN client to eth0
 | 
				
			||||||
 | 
					-A POSTROUTING -s 10.8.0.0/8 -o eth0 -j MASQUERADE
 | 
				
			||||||
 | 
					COMMIT
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Replace `123.123.123.123` with your VPN server's external IP address and `eth0`
 | 
				
			||||||
 | 
					with the external interface.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					This will forward TCP traffic on port 2222 to your home server. If you want to use
 | 
				
			||||||
 | 
					port 22, then you need to set the VPN SSH server to something else.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					A full example of `/etc/ufw/before.rules` with other ports included can be found
 | 
				
			||||||
 | 
					here:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					[https://txt.t0.vc/URUG](https://txt.t0.vc/URUG)
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Apply the changes to `ufw`:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ sudo ufw disable && sudo ufw enable
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## Client Setup
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Switch to your home server or client machine.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Install OpenVPN:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ sudo apt update
 | 
				
			||||||
 | 
					$ sudo apt install openvpn
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### Client Configs
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					For static IP clients (like your home server), create the config file `/etc/openvpn/client.conf`:
 |

 | 
				
			||||||
 | 
					### systemd
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					If it works fine, persist OpenVPN with systemd:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					$ sudo chown root:root /etc/openvpn/client.conf
 | 
				
			||||||
 | 
					$ sudo chmod 600 /etc/openvpn/client.conf
 | 
				
			||||||
 | 
					$ sudo systemctl enable openvpn@client
 | 
				
			||||||
 | 
					$ sudo systemctl start openvpn@client
 | 
				
			||||||
 | 
					$ sudo systemctl daemon-reload
 | 
				
			||||||
 | 
					$ sudo service openvpn restart
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					### Client Apps
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					On Android I use "OpenVPN for Android" and on Linux I use the
 | 
				
			||||||
 | 
					`network-manager-openvpn-gnome` Debian package.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					To add your VPN on Gnome, open VPN settings, import file, and select
 | 
				
			||||||
 | 
					`client.ovpn`. If the private key is missing, select it from
 | 
				
			||||||
 | 
					`~/.cert/nm-openvpn/`.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					## Closing Thoughts
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					You should now be fine to access your home server from over the internet.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					To forward additional ports, just edit the `/etc/ufw/before.rules` file like
 | 
				
			||||||
 | 
					above.
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					You can now point a domain to your virtual server's IP and use that to connect
 | 
				
			||||||
 | 
					to your home server. Use a CNAME to make it easy to change later:
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					NAME                    TYPE   VALUE
 | 
				
			||||||
 | 
					--------------------------------------------------
 | 
				
			||||||
 | 
					vpn.example.com.        A      123.123.123.123
 | 
				
			||||||
 | 
					myserver.example.com.   CNAME  vpn.example.com.
 | 
				
			||||||
 | 
					```
 | 
				
			||||||
 | 
					
 | 
				
			||||||
 | 
					Finally, make sure any server programs are listening / bound to `10.8.0.100` or
 | 
				
			||||||
 | 
					`0.0.0.0` so that they can get traffic from that interface.
