Setup script

You can hard code the server URL, federation port and access token for faster use, it will prompt you for these values if you don't.

Your access token can be found in Element > Settings > Help & About, your user account must first be upgraded to a server admin.

Upgrade user to 'server admin'

https://github.com/matrix-org/synapse/tree/master/docs/admin_api

“So first connect to the correct db and then run the UPDATE users...”

$ sudo -i -u postgres

$ psql synapse

synapse=# UPDATE users SET admin=1 WHERE name='@PC-Admin:perthchat.org';

UPDATE 1

synapse=#

‘-’ sign instead of ‘=’ means:

It means you didn't type a complete SQL query yet.

You need a semicolon to terminate the command.

Make sure /_synapse/ is mapped

A few of the commands will not work unless /_synapse/ is mapped to port 8008. Here is a example for nginx:

    location /_matrix {
        proxy_pass http://127.0.0.1:8008;
        proxy_set_header X-Forwarded-For $remote_addr;
    }

    location /_synapse {
        proxy_pass http://127.0.0.1:8008;
        proxy_set_header X-Forwarded-For $remote_addr;
    }

You can also run the script locally on your server if you do not wish to map /_synapse/.

rdlist Functionality

'rdlist' is a comprehensive list of child abuse related rooms on Matrix, it's a safety initiative led by the Legion of Janitors.

This script can automatically load and block/purge abusive rooms from rdlist, making it very easy for inexperienced administrators to block this harmful content.

To get started, reach out to @jon:glowers.club and ask for permission to access this repository: https://code.glowers.club/loj/rdlist

Once you have read access, simply run this moderation script like so:

$ python3 modtool.py 

Please select one of the following options:
...
#### rdlist ####
30) Block all rooms with specific rdlist tags.
('q' or 'e') Exit.
