8 | ## 1. Summary | |
9 | ||
10 | Syncthing is a decentralized file-synchronization program that permits | |
11 | sharing of files over the Internet with computers that have been | |
12 | configured to trust one another. | |
13 | ||
14 | ## 2. Instructions | |
15 | ||
16 | The following are instructions for installing Syncthing onto a GNU/Linux Debian 10 machine. | |
17 | ||
18 | ### 2.1. Install `syncthing` via `apt-get` | |
19 | ||
20 | Update the local repository package lists with `$ sudo apt-get update`. | |
21 | ||
22 | Install the `syncthing` package with `$ sudo apt-get install syncthing`. | |
23 | ||
24 | Note: As of 2020-04-27, Debian 10 Buster uses Syncthing version `1.0.0`. | |
25 | ||
26 | ### 2.2. Enable automatic startup via `systemd` service. | |
27 | ||
28 | Syncthing can be started automatically via `systemd` as a system | |
29 | service upon boot or a user service upon login. If `syncthing` was | |
30 | installed from the Debian 10 repository (ex: via `apt-get`), then the | |
31 | necessary service files (ex: `syncthing@.service` ) should already be | |
32 | installed. If not, see the detailed autostart instructions for where | |
33 | to download a copy of the service | |
34 | files.<sup>[[1]](#syncthing_20200331_autostart)</sup> | |
35 | ||
36 | #### 2.2.a. Enable automatic startup via `systemd` upon boot (system service). | |
37 | ||
38 | For a system service, identify the user under which to run | |
39 | `syncthing`. Even though `syncthing` will be run upon startup (without | |
40 | needing a user to login first), files cannot be created or modified by | |
41 | `syncthing` with permissions of a specified user. In this example, | |
42 | `baltakatei` will be the user. This means an appropriate directory for | |
43 | a `syncthing` shared folder would be `/home/baltakatei/Sync/`. | |
44 | ||
45 | Alternatively, if `syncthing` were running as a headless server where | |
46 | no user is expected to directly modify files in the server's file | |
47 | system, then a dedicated dummy user named `syncthing-user` might be | |
48 | appropriate. | |
49 | ||
50 | The commands to create a `systemd` system service under user | |
51 | `baltakatei` are: | |
52 | ||
53 | $ sudo systemctl enable syncthing@baltakatei.service | |
71687450 | 54 | $ sudo systemctl start syncthing@baltakatei.service |
55 | ||
56 | The following notifications may appear while running these commands: | |
57 | ||
58 | $ systemctl enable syncthing@baltakatei.service | |
59 | Created symlink /etc/systemd/system/multi-user.target.wants/syncthing@baltakatei.service → /lib/systemd/system/syncthing@.service. | |

60 | |
61 | The status of the new system service can be verified via: | |
62 | ||
63 | $ systemctl status syncthing@baltakatei.service | |
64 | ||
71687450 | 65 | The resulting status data will resemble: |
66 | ||
67 | $ systemctl status syncthing@baltakatei.service | |

78 | #### 2.2.b. Enable automatic startup via `systemd` upon login (user service). |
79 | ||
80 | For a user service, identify which user under which to run | |
81 | `syncthing`. In this example, `baltakatei` will be the user. This | |
82 | means an appropriate directory for a `syncthing` shared folder would | |
83 | be `/home/baltakatei/Sync/`. | |
84 | ||
85 | The commands to create a `systemd` user service under user | |
86 | `baltakatei` are: | |
87 | ||
88 | $ systemctl --user enable syncthing.service | |
89 | $ systemctl --user start syncthing.service | |
90 | ||
91 | The status of the new user service can be verified via: | |
92 | ||
93 | $ systemctl --user status syncthing.service | |
