We are currently setting up a test server for Matrix. We use Synapse. If everything goes well, we will set up a production Matrix server.

We are currently running Matrix on a Proxmox LXE container on citric-acid. Ask Siracha for the credentials to access Proxmox and the VM.

We are using NixOS, so the config to setup both Synapse and PostgreSQL is hosted at https://git.csclub.uwaterloo.ca/k95ma/matrix-nixos/.

The reverse proxy, Caddy is configured on citric-acid.

We are currently running mautrix-discord. Bridge to IRC via heisenbridge may be added in the future.

Create the Matrix channel to bridge to
Invite @beefbot:csclub.uwaterloo.ca and @discordbot:csclub.uwaterloo.ca to the channel
Invite the Discord bot to the bridged server using {{{1}}}. client_id is found by logging in to the CSC Exec account on Discord and going to developer portal to find the ID of the Matrix Bridge bot.
Login to User beefbot (ask syscom for password) on our matrix instance (when we eventually disable password login, you will need to edit the nix config to re-enable it)
Inside the matrix channel, send, !discord bridge <channel ID> (the channel ID on Discord, the Discord bot must be able to see that channel)
Create a Discord Webhook URL for that channel on Discord's side, and then DM the discord bot with !discord set-relay !26DmcJd3cQ...:csclub.uwaterloo.ca --url https://discord.com/... with the first argument replaced by the actual room identifier and the second parameter the webhook URL.
