ejabberd Notes

Published on 2023-08-30 by @danja

danbri mentioned XMPP (for ChatGPT) yesterday, it appears I have ejabberd installed. Is it running?

Browser-based client :

https://conversejs.org/docs/html/quickstart.html

Pro-tip, if you just want to quickly test things locally, you can run make serve inside a checkout of the Converse repo. Converse is then hosted at http://localhost:8000

• git clone https://github.com/conversejs/converse.js.git
• cd converse.js
• make serve (it does an npm install of stuff)

} from '../../../node_modules/lit/html.js'; // } from './html.js'; danny

cp node_modules/lit/html.js src/headless/utils/

grr, hateful thing, given up.

• yes | rm -r converse.js

Installed gajim (via synaptic) instead

no immediate joy (where to cofig servers?)

Installed pidgin

isn't connecting - the Enabled box for the account unchecks itself

• systemctl restart ejabberd
• systemctl status ejabberd

looks like the install is old, I think done from .deb So,

• wget https://github.com/processone/ejabberd/releases/download/23.04/ejabberd_23.04-1_amd64.deb
• dpkg -i ejabberd_23.04-1_amd64.deb

Unpacking ejabberd (23.04-1) over (21.12-1) ...
...
Could not execute systemctl:  at /usr/bin/deb-systemd-invoke line 142.

Oops!

• systemctl stop ejabberd
• systemctl start ejabberd
• systemctl status ejabberd

Grrr, Cannot ping watchdog again.

Yay!

From pidgin :

Host Unknown

Port problem? Whatever, enough of that for now.

Hah! The second I returned to Lemmy setup, I saw mynotes from when I installed ejabberd last time :
