update-plex-ipv6-access-url

DynDNS-like tool for keeping your Plex IPv6 custom access URL up to date, automating the IPv6 workaround for Plex as described on Reddit.

Features

• determine IPv6 address for a specified interface
• update Plex settings with plex.direct-domain using current IPv6 address

Command line arguments

If any required command line argument is omitted, the tool will prompt you to provide input at runtime.

Name	Description	Required	Options	Default
address	Plex server's address in format http[s]://host:port	Yes
interface	Name of network interface to use for IPv6 access	Yes
token	Plex access token (X-Plex-Token) How to find	If config is not given
config	Path to Plex config (Preferences.xml) How to find	No
use	Which IPv6 address(es) to use if multiple are found on the interface	No	first last all	first
capitalization	Capitalization to use for dashed IPv6 address in Plex custom access URL	No	upper lower	lower

Usage

A simple example: You are running Plex on an Ubuntu server and set Plex up to listen on the ens18 interface. Your Plex library resides in the default location, which is /var/lib/plexmediaserver/Library/Application Support/Plex Media Server. Assuming you are currently in the directory you placed the script in, you would run the script like so:

./update-plex-ipv6-access-url -address http://localhost:32400 -interface ens18 -config "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Preferences.xml"

Plex does not store the config on disk on all platforms. On those platforms, you need to manually specify an access token, as it cannot be read from Preferences.xml.

.\update-plex-ipv6-access-url.exe -address http://localhost:32400 -interface Ethernet -token your-X-Plex-Token

To automate the process, create a cronjob or other type of scheduled task in order to run the script regularly.

For testing or one-time use, you can also run the tool without any command line arguments and provide required input at runtime.

$ ./update-plex-ipv6-access-url
Enter the Plex server's address in format 'http[s]://host:port': http://localhost:32400
Enter the name of network interface to use for IPv6 access: eth0
Enter a Plex access token (X-Plex-Token): your-X-Plex-Token
