NZBGet

NZBGet is an Usenet-client written in C++ and designed with performance in mind to achieve maximum download speed by using very little system resources.

Installation

Install the nzbget package and the optional nzbget-systemd^AUR that provides a nzbget systemd service. Alternatively, install the development version from the Arch User Repository (nzbget-git^AUR), which also includes the systemd service.

Configuring NZBGet

Copy the template configuration file to a custom directory:

# cp /usr/share/nzbget/nzbget.conf /var/lib/nzbget/.nzbget

Update the configuration before starting NZBGet:

/var/lib/nzbget/.nzbget

..
WebDir=/usr/share/nzbget/webui
ScriptDir=/usr/share/nzbget/scripts
LockFile=/var/lib/nzbget/nzbget.lock
ConfigTemplate=/usr/share/nzbget/nzbget.conf
DaemonUsername=nzbget
..

Make sure the permissions are set correctly:

# chown -R nzbget:nzbget /var/lib/nzbget
# chmod -R 750 /var/lib/nzbget

Starting NZBGet

Note: The official nzbget package does not provide a systemd service file. You will have to start NZBGet manually instead.

Running as root in console-mode:
```
# nzbget -c /var/lib/nzbget/.nzbget -s
```

Running as root in daemon-mode:
```
# nzbget -c /var/lib/nzbget/.nzbget -D
```

NZBGet should now be accessible on http://localhost:6789.

Running NZBGet under a different user

Note: nzbget-systemd^AUR and nzbget-git^AUR already provide the nzbget user and user group.

See system user for an example and reasons why it may be useful.

After adding a system user, update the main configuration file using the webinterface or by manually editing /var/lib/nzbget/.nzbget:

/var/lib/nzbget/.nzbget

..
DaemonUsername=nzbget # system user
MainDir=/home/myuser/Downloads/NZBGet
UMask=0002 # 775 for dirs - 664 for files

Create and set permissions for the desired directories:

# mkdir /home/myuser/Downloads/NZBGet
# chown -R nzbget:nzbget /home/myuser/Downloads/NZBGet
# chmod 775 /home/myuser/Downloads/NZBGet

The will be accessible for the user nzbget and for the nzbget group. Making the target directory world read/writable is highly discouraged (i.e. do not chmod the directory to 777). Instead, give individual users/groups appropriate permissions to the appropriate directories (e.g. by adding 'yourself' to the nzbget group).

Starting NZBGet as user nzbget in daemon-mode, or start NZBGet by using the if installed with the instead:

$ sudo -u nzbget /usr/bin/nzbget -c /var/lib/nzbget/.nzbget -D

Troubleshooting

Default NZBGet credentials

The default credentials for NZBGet are nzbget as user and as password. For security reasons it is recommended to change the default credentials.

NZBGet crashes on start

This may happen when the user edited the NZBGet configuration by the Web-interface (located at http://localhost:6789), corrupting the configuration-file. Clean-up the configuration-file and restart the server/daemon again.

Alternative systemd service

The following provides an alternative solution for (re)starting NZBGet when using systemd:

/usr/lib/systemd/system/nzbget.service

gollark: So is mine!

gollark: The MOV instruction could take multiple output specifiers.

gollark: osmarksISA-2028™ had a similar feature, but nobody used it.

gollark: I don't know if it's useful to write to multiple registers at once, but it's cool.

gollark: Cool idea.
